Tested All Continuity on All Parts Dryer Still Wont Heat

I've been doctoring appliances and electronics for a number of years. I'm here to share the knowledge and experience I've collected.

There are a number of possible causes of this problem.

Dryer Not Heating?

So, your clothes dryer won't produce heat? There are a number of possible causes of this problem. The first thing we must determine is the type of dryer you have. There are only two types: gas or electric.

Warning: Before You Begin

Before attempting to repair any appliance:

1. Turn off (unplug or kill the circuit to) electrical power.
2. Shut off gas supply (if applicable).

Caution! Shut off all the power before you begin!

Step 1: Check the Power

If your dryer is electric, meaning it uses electricity instead of flame to produce heat, step one is to verify that the breaker to the dryer's electrical circuit is fully on. Since electric dryers require 240 volts to run, their circuit is run through a dual breaker switch. Sometimes only half of the breaker switch will be off, or will have failed, which may result in a supply of only enough power to make your dryer tumble but not enough for it to produce heat. Pop the breaker to your dryer off and on again and then see if the dryer will now produce heat. If it does, then have the breaker replaced. If it doesn't, you can verify that the dryer outlet is fully powered by testing it with a voltmeter. If the electric outlet is fully powered, then the problem definitely rests within the dryer.

If your dryer runs on gas, we will assume there are no kinks or stoppages in the line and the problem is in the dryer itself, although if you follow all the rest of the steps and still can't find the solution, you might investigate this as a source of the problem.

Continuity tester.

Step 2: Check the Dryer's Internal Workings

Let's next deal with the failure common to both types (gas and electric dryers). You will need a continuity tester for this process. Here are directions for how to use a continuity tester.

After you have disconnected the power or shut off the gas, you will want to access the internal workings of your dryer. Directions for achieving access, specific to your brand, can be found in your owner's manual. If you don't have one, you might try Google or searching YouTube to see if anyone has uploaded instructions for your particular make or model.

Most dryers have a thermal fuse located in the exhaust path. Depending on your dryer, the fuse will be found toward the front or the rear of your unit. Generally, if there is a removable back on the dryer, then that is where you will find the fuse.

The most commons thermal fuses you might find are shown in the illustration below. They are each roughly 1" in size. You will notice that the contact points are easily spotted for a continuity test.

In older units and in some electrically heated units, at various points along the heater assembly, you will find a series of thermal fuses that look like small tin cans. These will also need to be continuity tested before you can rule out thermal fuses as your problem.

If any of the thermal fuses fail the continuity test, then it needs to be replaced.

Your thermal fuse might look like this.

Step 3: Check the Heating Element (Electric Dryer)

After making sure your thermal fuse(s) is/are good, it is time to move on to the next most likely possibility: the heating element. This element is comprised of metal coils supported on a framework with two contact points where wires are connected to the rest of the dryer. A break in this coil will stop the dryer from being able to create heat. Test the two contacts for continuity with a continuity tester. If they fail, then you need a new heating element.

If both the thermal fuse and the element show continuity, it is time to call a professional to service your electric dryer.

Typical dryer heat element.

Step 3: Check the Burner Assembly (Gas Dryer)

Gas dryers use a burner system to create heat. This system has a number of parts that tend to fail over time: Some you can test but some you must simply read the signs and make a good guess to replace or not to replace the part.

Not all of these parts can be tested with a simple continuity tester. An ohm meter is now required to find your problem part.

The parts prone to failure in your burner assembly are:

• Igniter
• Coils
• Flame sensor

A burner operates in a fairly simple way. Once the motor is turning, centrifugal force closes the motor switch, allowing the electricity to reach the flame sensor. The flame sensor allows the electricity to reach the igniter, allowing it to heat up to a temperature high enough to ignite natural gas. Once the igniter is hot enough, the flame sensor breaks the igniter circuit, allowing the electricity to run through the coils that open the gas valve. Gas then flows out past the igniter and catches fire. The heat is drawn into the airflow within the dryer.

Internal workings of a gas dryer: burner assembly.

Troubleshooting Gas Dryers

Observation is key to troubleshooting a gas dryer. Does your dryer get hot at the beginning of the run but finish cold? Does it never heat at all? Do you hear a chattering sound at times?

If your dryer is hot at the beginning of the run but finishes cold, then it is likely you have bad coils. As coils age, they lose the ability to hold the gas valves open. Sometimes this will cause the valves to open and shut rapidly, resulting in a chattering sound. Unfortunately, you can't test the coils to verify the failure, so replacing them is a decision you make based on the above observations.

If the dryer never heats, then there are more items to check and test. The first item is the igniter. There is a Molex (clear plastic) connector attaching the igniter to the burner circuit: Disconnect this and place your ohm meter probes onto the two contacts on the igniter side of the connector. The meter should read under 100 ohms of resistance. Any reading above this value means that the igniter needs replacing.

If the igniter passes your test, then you need to test continuity on the flame sensor. You should have continuity between the two contacts. If not, then you need to replace the flame sensor.

If all of the above pass their tests, you need to make certain that there isn't a build-up of dryer lint around the burner. Sometimes, lint will impede the gas flow, preventing the unit from igniting.

If none of these things help, then it is time to call in a professional.

I have a,whrpool lp gas dryer the igniter come on the flame starts and burns, but is only about 2-3 inches long. I watch other gas dryers and the flame look large enough to fill the burner tube, any ideas?

I checked gas flow, replaced the coils and the igniter?

Phil on November 28, 2017:

I have a whirlpool gas dryer..it runs but does not heat. I looked and there is now glow. Would this be a good possibility of thermal valve?

Sheree Rowse on June 17, 2017:

They put new element in moms dryer worked3 days and now no heat?

jenn on April 16, 2017:

I replaced my heating element, thermostat and thermal fuse all at the same time, i was able to do 2 small loads of laundry before it stopped heating again. Checked all parts for continuity again and the thermal was open.so it blew out only after drying 2 loads of laundry???.... I just bought all 3 of these parts and put them in right before i done the 2 small loads of laundry... Why did it blow already? Lint is clean and electricity is fine to the plug in the wall. Electrical panal is fine...

John J Hoban on March 06, 2017:

replaced coils, ignitor and fuse still won't heat whirlpool dryer

Vinny on September 19, 2016:

Hi guys I have a Kenmore gas dryer from Sears. I remember once when a load finish drying as I was taking her clothes out and the machine was not running I spun the drum and I heard something click and since then the dryer is not heating whenever I cycle it for a dry model # 11070172002. Thank you in advance your output really appreciate it.

Robert s on September 14, 2015:

I have replaced fuse igniter and now gas coils. Still can't get get dryer to heat up. Can you help me with this?

Nelson on June 13, 2014:

This site has a lot of great info but I don't know if the Appliance Doc ever made it back to health. Sad

Steve on February 23, 2014:

I have an older model GE gas dryer. The heat comes on for one or two times and then runs cold the remainder of the dryer cycle. Sounds like the coils based on my research but I checked the coils with an ohm meter and they seemed to be ok. Any ides?

roberto on February 07, 2014:

I have a GE GAS Dryer Model DCVH680GJ2WW bouth 5/7/2010 and it does not have heat, my Igniter reads 185 ohms, I read above that it should be less than 100 ohm, I measure an Inlet control thermostat # 507, and a thermistor #240 and both shows open, I order a new parts and both shows open too, all the other parts in the dryer thermostat and thermistor reads OK, is the Igniter 185 ohms bad, and the thermostat and thermistor both open bad too.

Please help

Kerry Allen from SE Texas on November 17, 2013:

Hey Doc

I just purchased a gas GE Dryer used and everything works except there is no heat. In reading your article, you have a reference to figure 3 but I can't find it...

Am I just not seeing it?

garett on November 11, 2013:

My kenmore gas dryer works it spins but no heat. If changed the coils and still no heat. We watched the ignitor it glows up and seems like it wants to ignite but the glow disappears. Like its not getting any gas to ignite. Could it be the gas valve on the machine? When it starts up it sounds normal but then after couple seconds it starts making a funny buzzing noise. Then it will go away and come back..while that noise is happening the ignitor repeats itself to try to ignite.

bart clovis on November 09, 2013:

ive replaced the heating coil in my older whirlpool dryer and it tumbles but does not get warm

Paul on October 16, 2013:

Whirlpool CGM2941TQ1

The dryers gas valve mysteriously self ignites. No coins no manual reset, just cycles on and off like it was normally running. The drum does not turn when this is happening.

Please help! Thank you for your input. Paul

chris carney on March 24, 2013:

my dryer spins and the heating element tested ok and the thermal fuse tested ok but it still wont heat. the vent isn't clogged either. it did work last night but only one load. Help?

jostler2013 on February 06, 2013:

Thanks for the help, I've had some of my own troubles with dryers. Some of the biggest problems I have is that the heating element will go out. I like to do most of my own repairs but sometimes I just don't have time. If you are ever in need of an appliance repair in naples, you'll have to check out these guys http://www.alwaysspeedyapplianceservice.com, they've always seemed to be a great alternative for when I can't fix it myself.

james on December 17, 2012:

my dryer will not haet up

Cliff on July 13, 2012:

My Performa dryer (by Maytag) would fire the first time, but that was it. Timer wouldn't move (apparently it only moves when the flame is on). I checked the coils with a meter, and they measured spot-on (see above). Still, I saw other people had the same issues, had good readings, and still replaced the coils. I found a set for less than $8.00, including shipping, so there was little risk in replacing them. Once replaced, the dryer is working fine, and the timer operates correctly as well. So my story is basically that the coils were weak and failing, even though when I'd checked them with an ohm meter they appeared to be fine. If your dryer does fire, but only once, or intermittently, try replacing the coils... It can't be the thermal fuse or sensors if the gas still comes on at all. It likely isn't the ignitor if you get a good, bright glow. Replace the coils - worked for me.

Claire on June 10, 2012:

I have a gas dryer won't heat as of yesterday afternoon. It does turn on. We had power out in a few outlets in the house one on the same wall (opposite side) of the dryer. I think somehow the pilot went out? Any suggestions?

Thanks!

patfussy on May 26, 2012:

I have an admiral electric dryer,it died on me and through different channels figured out it was a bad thermal fuse. I replaced it and the dryer is running again...only now it won't heat up. Any help would be greatly appreciated.

Alex on May 14, 2012:

Not getting igniter glow on a (Whirlpool) 80-series Kenmore gas dryer. Checked thermal fuse first, resistance is near zero. Checked igniter, looks good and resistance is 76 ohms. Suggestions on what to look for next? Thanks for your help.

Tim on April 17, 2012:

On an electric dryer should you see sometimes see a glowing or light at the bottom of the dryer? We had ours out from the wall after we had cleaning out lint from the duct. Also should the back where it sticks out on the left side feel really hot?

Thanks for any help.

Gman on April 15, 2012:

I have a whirlpool electric dryer that wont heat , I have replace the thermal fuse , heating element and the piece that goes into the heating element and still does not get hot . Flip the switch on the fuse box , is there anything else that I need to do .

Dot on March 29, 2012:

I have a kenmore 90 series and it runs but does not get hot...we do not see any flame when turned on

Mike N on March 28, 2012:

Read previous blogs (thanks) approx 2 years ago replaced 2 bad gas valve relays to solve dryer heat on /off problem & replaced ignitor for good measure. Now ignitor does not glow when dryer is running, measured 75 ohms & inspected ignitor which still looks new. Tested flame sensor, 0 ohms & checked relays which checked OK. Drum rotates and no obstructions in vent or dryer. What next?

Lori on March 24, 2012:

I can see a coil light up but no flame. Any suggestions? Gas Dryer.

DAR on March 20, 2012:

my dryer works and then shot off by it self we have to wait until cools off.likes over heats....help me please.

frieda on March 16, 2012:

i have replaced the heating element the thermal fuse checked the breaker its good and the dryer still has no heat so what else could it be

wallytiger on March 11, 2012:

To follow up on my Amana dryer: apparently replacing the thermal fuse alone did not do the trick. I had to change the thermostat too. Once both were changed, my dryer has been working since.

Jim on March 09, 2012:

I have a Kenmore Ultra Fabric Care 27" gas dryer. I get no heat although the dryer works fine otherwise. I have already replaced the thermostat and tested the Igniter, which got 69.5 ohm. I also tested the flame sensor and thermal fuse and have continuity on both. I'm at a loss where to go from here. I also had the temperature control switch off, but could not tell if it was bad and couldn't locate a replacement. I have the dryer pulled apart, any help would be appreciated.

Bo on March 07, 2012:

Great path to diagnosis - thanks for laying it out for me! I took the fuse off today - and I'm getting a new one this weekend. I hope it works - but even if it doesn't, you really laid out the options perfectly. THANKS FOR THE HUB PAGE!

wallytiger on February 21, 2012:

I have an electric Amana dle330raw dryer that a wire to the thermo fuse cutof blew. The thermo fuse cutof works but test shows the thermo fuse itself is bad. i replace the thermo fuse and the dryer worked for a day and the same wire going to the thermo fuse cut of blew again

jkunkels@aol.com on February 19, 2012:

bypassed the thermal fuse and was working fine so ordered a new one. In the mean time I moved it while it was running and the bypass shorted out, and now is not working again. What to check next.

ale on February 08, 2012:

my dryer does heat up after 6 hrs running and it takes like 4 hrs to dry my cloths what could be wrong?

Enzo Piccinini on January 31, 2012:

@ thebombsteak

1) replaced the glow igniter - STILL NO GLOW

2) replaced thermal fuse - STILL NO GLOW

3) replaced coils - STILL NO GLOW

----Try testing the flame sensor, one of the more common part to go out.

Penny on January 21, 2012:

After changing the solenoids, the problem persisted. The gas would light for about ten seconds and then shut off pretty much for good. My wife pointed out that there's was no lint in the filter. So I started thinking "clog" somewhere inside the dryer. Only after tearing the thing apart front and back did I think to look INSIDE the dryer. Eight softener sheets were fused to the exhaust outlet! Ho ho! That was easy!

Jess brewer on January 21, 2012:

Our dryer won't light up or put out heat would that be the heating element or something wrong with our breaker. It worked with a large load of clothes in it last night but I places a smaller load in it today an it won't heat. The dryer kept blowing the breaker last night could that have something to do with why it won't work now?

charles new york on January 12, 2012:

i have a whirlpool gas dryer stopped drying i changed the ignitor still no heat PLEASE HELP

al on December 20, 2011:

I have a Maytag dryer I change coils and thermostat. Before the igniter wasn't working. and that problem solved but right now "when I shut the door and start, there is no heat. the igniter comes on but the pilot light doesn't turn on, but when the door is open and press the door switch to make it start, the pilot works and the dryer is working fine. I was thinking it's an air circulation problem maybe the air goes to the pilot and blowing straight to the pilot. I tried to find the problem but can't trace any. Any Ideas.

Joe on December 12, 2011:

I have a strange one. Am renting the house, so when not heat, the owner replaced it. About 10 days later, no heat again, with a NEW dryer. The ignitor glows but shuts of in about 10 seconds. Therefore the problem is outside the dryer, right?!!?

I can see gas supply valve is open, and electrical is good (drum spins, ignitor glows) but no heat. Wondered if it was able to detect jammed exhaust pipe (ours goes to rooftop) so I removed the vent pipe and IT WORKED... ignitor, fire, heat, and dry clothes. But only once. Now with vent pipe removed we get no heat still. Suspect gas now?

HarryJ on November 15, 2011:

I have a Whirlpool Electric Dryer Model # LEC 8858EZO for a few years. No problems so far and today I find that the clothes when dried are not warm. Looks like the heater is no working. Any guidance/suggestions/recommendations please would be appreciated. I am unemployed and cannot afford to buy a new one. If I can repair it myself, that would help me. Thanking you in advance. HarryJ

Mike on November 04, 2011:

Greg, I had the same problem, it ended up being a thermistor located on the blower of my kenmore elite dryer.

Billgator on November 04, 2011:

I replaced my solenoid coils and now my gas dryer functions properly. See my above post for the symptoms.

Rey on November 04, 2011:

Hi Justin, Im not the DOC or a pro but the first thing i always check is the Thermal fuse (most common prob i come across) if circuit is open replace...

justin on November 03, 2011:

i have a whirlpool gas dryer and i have NO heat at all,ive changed the •Igniter

•Coils

•Flame sensor

what else could possibly be wrong im not very handy but i cant afford to replace the dryer what else can i do?Please help thanks

Billgator on October 31, 2011:

I have a Whirlpool gas dryer model LGQ8858HZ0. My dryer starts up and runs with flame for 4-5 minutes. The flame then cuts out and the dryer will every few minutes try to reignite. Nice glow from the ignitor but no ignition. There is also a funny sound preceeding the ignitor glow which sounds like a penney sliding around in the drum. Not banging around but sliding. If you let the dryer cool down it will reignite but then kill the flame after 4-5 minutes.

greg douthit on October 30, 2011:

Have Whirlpool elec dryer. replaced both fuses and coil. Worked for a couple of days now back to no heat.

aa8rv on October 30, 2011:

Hi,

I'm suspecting a bad thermal fuse on my Kenmore 27 inch electric dryer as the reason why it runs but does not dry. Where can I get this thermal fuse for my particular model? And more importantly, I got confused on the wiring points to the three separate units that are on the heating element vent including the thermal fuse(in other words, which wires go to each fuse) I see that the wire prongs are different in size on some wires and that helps.

Thanks

linda on October 26, 2011:

my dryer wont heat up

Tim on October 05, 2011:

When I start the dryer it turns on then there is a loud click and I can see the burner light with a large flame. A short time later it goes out and stays out. No smell of gas just wont re-light. Afetr a few trys...its repeats....on, click, flame....out. Please help! Thanks, Tim. tbusb@comcast.net

crystel rodriguez on September 26, 2011:

hi!i have a kenmore electric dryer,it doesn't make heat and the timer knob don't rotate. what could it be.

Jemma on September 18, 2011:

Thanks for the help. Also Jenni I am going to have to agree with things going out faster because they are cheaply made now. My parents have the same one they had when I grew up. :3

Dolly on September 01, 2011:

We bought a dryer at a moving sale and it is farely new. The dryer was in working condition when we got it and we did see it run and it did put out heat, we loaded it up and brought it home and now won't heat. It tumbles and works like that, but no heat at all. It is a GE dryer and the model # is DBSR453EB3WW.

Jenni012578 on August 27, 2011:

Is the heat going out common, my dryer is only 6 years old. I remember my mom having her dryer 30 before she had problems LOL I will have my husband try these things first. Thanks for trying to help us save a few bucks. Vacation is comimg quick :)

Rick Spero on July 31, 2011:

My dryer stoppped heating and I found your website. I saw your troubleshooting steps from 2 years ago and tracked the problem down to a bad thermal fuse. Thanks so much for your advice!!!!

Linda on July 27, 2011:

Being a recent widow, I had no idea why the dryer would run but didn't have any heat, or how to fix it. After reading the article I turned the circuit breaker on and off a few times, and it worked! Thank you

mary Smith on July 14, 2011:

go out side and run a wet and dry vac in the lent trap outside and suck up all the water then your dryer will work I had to do that the other day now mr dryer dried my clothes real fast.

mike on July 10, 2011:

I have replaced the coils on my maytag dryer. I checked the ignitor and it is getting continuity but it is not glowing. Is my problem with the thermal fuse(dryer runs but not heating)or is my problem the ignitor?Thank you for your answer! mleh1228@aol.com

Tim S on July 04, 2011:

I have a gas maytag dryer and it is about 10 yrs old. I unplugged the unit and checked all the fuses. All have continunity except the heat sensor. My problem is that the igniter does not get hot because it is only getting 28 volts to it, so it will not trigger the heat sensor which tells the gas valve to open. Why am I only getting 28 volts to the igniter?

mtleggat on July 01, 2011:

I have an electric whirlpool dryer and the heat doesn't work and neither does the timer (on both auto and manual). I tested the thermal fuse and it has good continuity....any suggestions?

margie100 on June 04, 2011:

the dryer wont heat.I do believe it mite be the volts cause this is the 3-4th dryer I've been thru the first 3 wre used but this one is new so do you think it could be the voltage?that dsoes entail checking the breaker rite or is the breaker on the dryer?Please answer soon thanks

caleb on June 02, 2011:

Whirlpool gas dryer. Igniter heats up for a few seconds then goes out. Replaced coils. Same thing. What is the next step?

Lightnin Jones on March 08, 2011:

I have a GE DDG7985SBLWW gas dryer that isn't heating. Drilled a hole low in the burner side of cabinet to view "the glow" - no glow. Then I ran continuety tests on all electical "doo dads" I could see and find. It all tested ok on ohm meter - 3 thermostats, igniter, both coils, heat/flame sensor, and belt tensioner switch - all beeped on my tests. But upon my checking voltage at the connector to the igniter, expecting 110/115v I had no voltage at all. Thought maybe because the motor/belt switch was "open" from the belt being off, voltaged was cutoff from motor to the heating circuit. Leaning towards reported difficulty in obtaining accurate coil readings, I went and bought new coils and just to be sure, I thought, a new round igniter. Reassembled and tried it - still nothing . Motor runs fine, but still no glow, no ignition of gas, and upon rechecking, no voltage at the igniter connector. Schematic indicates under these conditions to test and confirm function at flame "detector", Timer TA TB, Heat Switch (? one of the 3 "stats" at back of heating chamber up on duct leading to disperser, that I checked and were ok?), Motor Switch 1&2 (only one I see is Belt SW)and last but not least - thermostats. I even checked the "EOS" next to the timer and no current or beep. I didn't really understand the TA TB part, can't say on success or not. there is a little gizmo wedged on the motor winding itself with red wire ,looks like, leading into winding. All ducting is spotless, vent is way free. I ws thinking about buying the flame detector just becuz, but have reservations about the lack of voltage at that igniter connector. Any thoughts? Thanks in advance.

David on March 03, 2011:

I have a Kenmore gas dryer and have no heat. I first changed the ignitor and then the radiant sensor. Both have not helped and seems like no electric is getting to ignitor, since it's not lighting. What do you think is issue? What regulates electric to the ignitor? Is there a fuse or switch issue?

Tami on February 16, 2011:

My fridgedair gas dryer gets warm but not hot. When I start the dryer it turns on then there is a loud click and I can see the burner light very brightly. After a few seconds the glow dyes down and there is a slight glow but not very bright, then it goes out. It does however seem to cycle, relighting and the same thing occures. The dryer does seem to be blowing luke warm air but does not get HOT. I thought it was the ignighter but now I see that it is lighting. It seems it will not hold its initial heat. I cleaned it very well, with no success. It is not real old but has seem alot of use. Everything else seem to be in tip top condition but with very little heat. Can you help me trouble shoot this problem. I am very mechnically inclined, but as the parts are not cheap I don't want to over shoot the problem

kelvingriffith on February 13, 2011:

kenmore dryer-gas.problem I thought was an electric ignitor. I replced it it didn't glow. now I wondering is could it be the flame sensor? is it the part that set on tin housing,square piece with the word them-o-disc?

Johnnie on February 13, 2011:

Same as above, I have an electric dryer which will heat up for 1 minute then shuts off for one minute all though out the cycle. I've changed all 3 Thermal Fuses. Your help is welcomed. Thanks

joe on January 28, 2011:

i have a GE 2 cycle electric dryer model #DDE5100RALWH with the same problem as sams above, the tumbler comes on with the heating element but the heating element shuts off after about 15-60 seconds... n e suggestions Aplliance Doc!?!?

Sam on January 22, 2011:

electric dryer heating element heats up (glows) for about a minute then shuts off. Motor running and air coming from exhaust. Should I replace the thermostat

KirkNY on January 18, 2011:

I have a Maytag LSG7806AAE stacked gas dryer that has completely dumbfounded me. I consider myself a pretty competent DIYer and can't figure out this issue and hoping you may be able to provide some insight. When I start the dryer the ignitor heats up, the coils release the gas valve and the flame starts. The ignitor then turns off and the flame continues until the ignitor is no longer glowing. Once this happens the coils click and shut off the gas valve. This happens throughout the entire drying cycle and results in very little heat to the clothes. I have replaced the coils as that was an immediate concern of another person I reached out to for help but that did not change anything. I have checked and confirmed continuity with the thermal fuse, the gas cycling thermostat's outer two contacts, the cycling thermostat, as well as the thermal sensor. At this point I think I've eliminated all potential issues - any I'm missing? Please help!!!!

Lisa on January 17, 2011:

sorry didn't mention, gas dryer thx

Lisa on January 17, 2011:

Whirlpool LGR663 series, not heating, ignitor lights, flames for 30 seconds then click and off, ironic as was repeating this process till i replaced the hilimit thermostat,now no repeat just goes out, I have replaced the coils, the ignitor, both thermostats, appliance parts store told me that the it was not the flame sensor that those never are really the cause, help, I am out of parts and patience. thanks

Rebecca on January 15, 2011:

We have an electric kenmore dryer, it tumbles fine but no heat we have changed the breaker (thing in the box in the basement), the heating element in the dryer and those can looking fuses and still no heat. What we we missing?

thebombsteak on January 14, 2011:

Hi there,

Hoping you can help!

i have a Kenmore 70 series gas with NO glow from the glow igniter, so I:

1) replaced the glow igniter - STILL NO GLOW

2) replaced thermal fuse - STILL NO GLOW

3) replaced coils - STILL NO GLOW

can you PLEASE let me know what direction i should be looking now? Thank you!

Kevin on January 13, 2011:

Hi there,

Hoping you can help!

i have a Kenmore 70 series gas with NO glow from the glow igniter, so I:

1) replaced the glow igniter - STILL NO GLOW

2) replaced thermal fuse - STILL NO GLOW

3) replaced coils - STILL NO GLOW

can you PLEASE let me know what direction i should be looking now? Thank you!

I followed your instructions and found my igniter to be bad (cracked no reading). I replaced it and I'm back in business. Thank You Very Much and Merry Christmas> : )

I've cleaned out the lint throughout the dryer and vent, but when I have the vent pipe connected the dryer will heat, then shut off after about 10-15 seconds. If I disconnect the vent, the gas flame stays lit. Is this indicative of a faulty coil? I've swapped the thermister.

Where do I find the heating element in a whirlpool dryer

My dryer is working but, there's no heat coming from it, therefore my clothes won't dry. I'm totally clueless of what to do because I have no knowledge of machines. HELP!

I've determined with my electric dryer that my outlet is bad. It tests for 110 v on each side, but I don't get a 240 v reading... which is why it is running, but no heat. What now? Do I need new breakers or an electrician to rewire a whole new outlet?

I have a Whirlpool gas dryer. There was no heat so I determined I needed a flame sensor. I've replaced this and it heats up for about 10 min and then the light goes out and no more heat. I've cleared all lint....can't figure out why it will heat for 10 min and then the pilot goes out? Suggestions?

Thanks so much for laying this out. After reading this I was able to solve the problem in no time.

My 8 year old gas Maytag dryer quit drying. I took the front cover off to see if the igniter was working. It was. The gas came on fine and it heated. I cleaned all the lint out and vaccumed inside the motor area and then vaccumed the vent duct. I put it back together, put my clothes in and it didn't heat again. I repeated the entire process again and again, it ignited fine while I had the front cover off. I even disconnected it from the vent duct just to see if it wasn't venting and tested it many times. Every time, it ignited just fine. It seems to not heat when the front cover is on and it has clothes in it. Any ideas?

I have a Maytag dryer (MDG308DAWW). The dial was not advancing in "auto" dry mode. It would advance in timer mode..but clothes were not drying. It would heat for about 4-5 mins, and thats it. I took the front off the dryer(leaving the door switch wires connected), and watched the burner. It would light the first two times but not the 3rd, 4th, 5th, etc...times. After reading these posts (and conformation from my local appliance store)...I replaced the gas coils. Perfect! My dryer works now. Thank you Appliance Doc! For $30 I have a dryer that works like brand new...it could've been at least 5 times that amount if a service tech made a visit. Hope this helps some of you out.

Hello. I have an admiral gas dryer that heats up for awhile and then cools off and more often than not doesn't finish cycle, just keeps running. Timer makes a constant noise in the 30min time mode, which I don't ever use til recently. Is this a bad timer or cause by bad coils. I have tried to clean out all dust/lint thouroughly. Thanks for your help!

Hi

I am checking the thermostats in my Alliance Gas Dryer but one has 6 connections (511957) how can I test this? Also I have only found one other thermostat on the burner housing, it tests fine, are there any more I could be missing? I tested the igniter it was fine, then dropped it and it broke:) Symptoms are that it spins but igniter doesn't warm up, so assume thermo failure?

Thanks in advance!

Ben L on September 19, 2010:

Thanks so much for the helpful troubleshooting. I followed the suggestions in the Maytag repair instructions(Modern gas dryer) and ended up buying a control board($200) when after following your guide, found out it was the ignitor.(500,000 Ohm resistance) The guide had me only checking the thermister, thermal fuse, valve resistance etc...NOT the ignitor resistance! Unfortunately, I cant return the board, but have learned a great deal in the process. I'll come here first next time!

Hello,

I have a Whirlpool gas dryer. No heat! I looked into the portal and restarted the unit and the glow igniter does not come on. Took it to a parts guy and he tested it at 55 ohms and said it is good. I took the 2 thermal fuses off of the back and the one thin white fuse as well off and will be taking it in for testing as well. My question is ....if any one of these fuses are shot will it prevent the igniter from glowing? I assumed that they detect heat not sure if they "communicate" with the igniter itself. Also is it normal for the 2 thermal fuses to rattle when shaken? Sounds like something loose in the disc part of the fuses. I know...silly question!

The flame sensor connection is broken. No heat, so why...

Why would you need to disconnect the gas line on a gas dryer if the dryer in not plugged in for power?

Jennifer on September 04, 2010:

Whirlpool gas dryer, push start button dryer comes on and drum spins, glow, gas comes on, starts to heat and after then the gas goes on and off like it should but does not stay on long enough to heat and then starts to make a clicking noise when trying to heat. Took dryer apart many many times. Please help.

Kenmore gas dryer stars,glows,blue flame visible and runs for 3-4mins then falme shuts off no heat. After it cools it will do the same thing. Is this a thermostat problem?

i have a kenmore gas dryer that isn't heating up and the timer isn't going off either it just keeps running? i changed the ignitor with no luck, what's next the flame sensor???

Ron on July 08, 2010:

I have a Kenmore Elite Dryer that is about 4 years old. My wife claims that when she turned the dryer on, it made a popping sound.

She went to check the breaker and sure enough, it was trippped.

She flipped the switch back to on and turned the dryer on.

It runs but has no heat.

I've had the fuses/coils checked and they are good.

I will be checking the voltage next.

any other ideas on what the cause might be??
