--------- Before you get started UNPLUG the dryer ---------
I use a 1/4” nut driver to remove 4 bolt-head screws just above my drawer pedestal. If you don’t have the pedestal these will be a little tougher to get at. Some dryer models may only have 2 bolt-head screws holding the front cover in place.
Inside we have easy access to the gas solenoids, but I suspect that mine are ok (even though I ordered a replacement set just in case). To get easier access to the Thermal Fuse and Thermistor, I remove the metal lint trap (4 more 1/4” bolt-head screws).
Before removing the wires to the Thermal Fuse and Thermistor, I label the wires, and then gently pull the connectors until they release. These were very tight fitting, be careful not to force or break them to get them off. The Thermal Fuse is attached with a single 1/4” bolt-head screw, because of limited space I use a 1/4” box-end wrench to remove this and the two screws holding the Thermistor.
Next step is to test these parts on the bench with our multimeter.
The Thermal Fuse can be tested with continuity, our old fuse is certainly bad. This part at time of repair cost me $5.19 on Amazon!
The Thermistor is tested with ohm resistance, and our old one looked to be nearly the same reading as the new one I ordered. As a precaution we’ll drop the new one in while we’re here. At time of repair this was $7.97 on Amazon.
The likely cause of my Thermal Fuse failure is build-up in the dryer vent line, so I did a thorough vacuuming of the lint trap and vent pipe and will be replacing my flexible vent line this weekend with a rigid metal vent pipe.
Before putting everything back together, I also replaced the foam gasket around the fan on the lint trap. Mine had partially disintegrated and was allowing lint into the dryer interior (not good).

Thank You! I'm a 65 year old woman and I was able to follow your super clear and easy to follow instructions to fix my 17 year old dryer. Only difference was that I had no problem getting the gasket to stick. Woo hooo!!!!
So awesome, we’ll done!
I also have a 17 yo dryer. Hoping to fix it this week!
Awesome instructional video Matt. A gift to the world! Thanks! Got my kid to watch and do the steps! A teachable moment!
Matt, Thanks a Ton for making this detailed video! I had no idea how to test the continuity and resistance, but from watching what you did, i was able to check the parts on my dryer. You're amazing!
Glad it was helpful! hope you got it fixed and saved some money!
Thaks Matt! Very nice video and part/tool links! And you are correct, getting those two terminals off of my thermal fuse was hard!!! I kept thinking there may be a locking clip -but no, just need to carefully pry off with a flathead screwdriver.
Just fixed my duet dryer following your instructions Matt, it worked great! Thank you for your outstanding video class! 👌👍
Fantastic, always happy to hear I helped someone save some money! Well done!
Just saved me about $250 dollars, thank you sir for the precise instructions.
Always happy to hear someone saved money! Well done 👍🏼
Matt, thank you very much for your instructions and beautiful jobs. Best wishes!
Good luck with your project.
OMG, these instructions couldn't have been better! I ordered the parts from Amazon, got them and spent about 1 1/2 hour installing! It really worked! (And I'm challenged with this stuff). I didn't lose a screw, Took these parts out, Put the new ones in and it started right up! Thanks, Thanks, Thanks!
Well done Bill! Glad it was helpful :)
Thanks! Same thing happened to my Whirlpool Duet! Fixed it good.
Well done!
Thank you sợ much for your video and times
This video was perfect the best one on all of RUclips
Thanks for doing this video and posting it's save me lots of dollars.
Thank you so much for the detailed instructions. This is the third time I've repaired our dryer with your help through your videos. The first two were F01 errors - those were fun opportunities to practice soldering skills). This time the dryer wasn't heating. Watched your video and I promptly ordered the parts via the links you shared. When they arrived I thought that maybe I should have checked a manual for the dryer model I own just to confirm that I had the correct parts. Your dryer in the video looked like an exact match to mine, but what if it wasn't. Interestingly the manual I found online had a very different looking thermal fuse. I worried that I had the wrong part, but before returning it to order the part shown in the manual, I thought I should open up the dryer to double check. Sure enough, the parts in your link were exactly what was needed. Dryer's working again and we saved time and $$$. Thanks so much!
Karean, nice job. Check that your vent pipe is clean and not clogged. Often as these build up with lint the dryer will get hotter than it should which causes the fuse to blow as a safety measure.
@@MattsGarageMiscDIY Yup. It seemed to work great then shut off again. Cold damp clothes at the end of the cycle. {{grrr}} Took the machine apart again to check the solenoids with a multimeter - both good. Then pulled the maching out to check the vent hose. That was embarrassing. Bought a new hose, cleaned out the vent outlet in the wall, and tried it again. This time I realized that the flame after the first repair was orange. After cleaning and replacing the vent hose, the flame was blue. First load worked great. Second one .... @#%^ Should I check the thermal fuse again?
@@kareanwrightson3864 If you have a multimeter you can quickly check the thermal fuse for continuity. Recently I had to swap the solenoids on my dryer. They'd work when cold, but after one or two cycles (10 minutes into drying the dryer would no longer light). The igniter would glow nice and bright but the gas valves wouldn't open... ruclips.net/video/dyKubdUM-RI/видео.html
@@MattsGarageMiscDIY just a quick update with thanks, again. I ran out of time to devote to continued attention to the dryer repair so I called a local, highly-regarded, repairman to come check it out. He said everything I'd done to that point was great. I just missed cleaning the exterior vent exit and the cage that surrounds it. He said I did everything that he would have checked or done in the process of figuring out where the problem might be. Deduced that the only thing it could be at that point was the gas valve. He replaced that and it's working great. While he was there he also gave me some diy tips for the washer, opened it up, and showed me a couple of things to maintain and watch for. Thanks, again, for your terrific videos and instructions!
Thanks so much saved me a new washer!
Glad it was helpful! :)
Thanks for posting.....saved me a service call and likely a couple hundred $$$.
Glad it helped.
Ours turns in by the element never turns on. Installed all new parte.
Great video
Can the igniter flame cut on & off and it still be the thermal fuse that is bad and not the coils??
My coils are testing good.
With my bad thermal fuse my dryer was not igniting at all. Now it cycles heat on and off as needed depending on the heat setting.
What size are the little bolts to take cover off? 1/4?
Thx 🙏🏾 !!!
Glad it was helpful.
Great video. How did you remove the wiring from the thermal fuse as for being tough to removed.
It should wiggle free, but take your time, you don’t want to pull one of the wires out of the connector. I was gripping the connector, do not pull on the wire. Good luck!
hello I have been given a whirlpool dryer and where I live there is no gas in the laundry room and I have tried drying but it does not heat gas is required
Hey man mine is newer one~ish and looks like yours but is in like a sea foam green color. I replaced both the thermal fuse and the other piece you installed but it still doesn't produce heat. Do you know what might be the cause?
Another fairly common culprit may be the gas solenoids. they are also inexpensive and easy to reach on most models. There are some good RUclips videos that demo how to test yours for proper resistance. Best of luck, you’ll get it!
Fuses series are devices so it doesnt matter which wire is right or left, whats more important is that you label wich fuse they belong to
This is true, as I take things apart that I have never fixed before, I like to label so that I can put it back exactly how it was.
Matt thank you!
My igniter works and the flame turns on, but I have to cycle my clothes 2-3 times for them to dry ! Any ideas ?
I have the same dryer as the one in this video also!
Ben, I wonder if yours is doing what mine was in my other video. When cold (not having run in a while, it would light and cycle heat a few times, and then mid cycle it would stop lighting (it would glow bright to ignite, but no gas to actually fire). You'd need to remove the bottom cover and watch it to see if this happens. Check this video: ruclips.net/video/dyKubdUM-RI/видео.html
Good luck!
Do you have a recommendation on process for this model, but electric? Is the fuse different?
Mickey, I don’t have any direct experience with the electric version. So sorry.
Where do you get the thermafuse? And other part? Would lowes have it. Or I need to order online
Clarissa, I bought the parts from Amazon, links are in the video description.
i have the same exact driyer but mine is electric. will this parts work for it ?
I don’t have any experience with an electric version, but imagine it might also have a fuse. Pretty easy to open up and have a quick look around. If you have a multimeter you can remove and test parts. Best of luck!
@@MattsGarageMiscDIY thanks a lot for your reply !👍
Is it normal for flame to go on and off ever other min got the same dryer ??
C Ray, my understanding is that it is normal for the flame to cycle on and off, and it’s dependent on how high you set the heat. On a lower temp it will not stay lit as long and then only relight as needed to maintain the heat setting.
Hi, I see that you unplugged the dryer, but what about gas? Where do I shut off the gas?
Joanne, behind the dryer in addition to the electrical cord, you should have the vent line that exits the home, and a smaller flexible gas line connected, often with a yellow colored valve handle that you can turn to shut off the gas. Hope that helps.
Can i blown thermal fuse cause it to spark and trip breaker when pushing start button
Kim, the thermal fuse will blow if the dryer is getting dangerously hot (to prevent fires). This wouldn’t happen at initial start-up. Usually it’s a symptom of the lint vent being clogged up and not flowing enough air to keep things within the safe heat range. The fuse is easy to test, and cheap to replace if yours is bad. Good luck with your dryer repair!
Thank you for these instructions, but my gas Whirlpool duet dryer has a similar problem that these instructions didn't help resolve. I appreciate any further tips! I did replace the thermal switch and thermistor, but my problem recurred. Here's what happens: my dryer is idle for at least half an hour. Then I put a wet load in and start it. The gas will ignite and run for about 2-3 minutes as normal. Then a high pitch sound starts coming from the bottom. About a minute later the flame extinguishes and shortly after the high pitch sound stops. The drum keeps turning and I can see the igniter glowing on and off every minute trying to reignite the flame, but the flame never ignites. Keeps doing this until I cancel the cycle.
If I try to re-run it within 5 or 10 minutes, the igniter glows on but the flame never ignites. The drum runs without a flame. I have to let it sit still for at least 30 minutes to get it to re-ignite like before and only for just 2-3 minutes as mentioned, then a high pitch sound, etc..
Does anyone know what could be causing this? It is behaving like this with the older and the newer thermal fuse and thermistor. Thank you!
Check out my other video where something similar happened with my dryer. In my case, the Gas Valve Solenoid Coils needed to be replaced. Easy fix, inexpensive, hope this helps! These over time stop working when they get warm, which is why when cold it will work for a light, and then during the cycle they stop working as they get warm. ruclips.net/video/dyKubdUM-RI/видео.html
@@MattsGarageMiscDIY thank you very much! Yes, that turned out to be my problem too. I just installed a new set of coils and the dryer worked like a charm. Thanks again for this tip!
Matt i have a question, like an idiot I broke my multimeter as I was grabbing it to check the thermostats so as of now I just bought some parts that I'm guessing is broken so my question is this. When the dryer is on I see no glow or ignition, do these pieces effect that or should I have bought the solenoids instead? FYI im still waiting on the new thermostats to come in so everything is still original
A couple years back my sister who has the exact same dryer as mine had the no heat issue. In her case it proved to be the solenoids. When my dryer stoped heating I was pretty sure it’d be the same thing so I ordered solenoids, but added the thermal fuse and thermistor because the parts are cheap and I figured if I’m in there I’ll check or replace it all. As it turned out MY only real issue was the thermal fuse which likely failed due to my partially clogged vent pipe. Now I have solenoids on hand for when that day comes.. Good luck with your fix.
There are other potential causes, bad igniter, even a bad dryer door switch could cause problems, but the fuse, thermistor and solenoids are worth a go.
Vic, sorry forgot to mention that my dryer was also not igniting like yours. In my video the bad fuse WAS the fix, but there are as mentioned other possible weak links in the chain.
How come everyone else’s dryer they can find the thermal fuse so easily as almost as if it were in plain site. I’m tryna find the thermal fuse in my dryer and that crap is nowhere to b found. I’m getting really pissed off about it
I replaced both of these parts but no luck. I have ignition but no flame. Ignitor starts to heat up then fades away and stop. I never get any flame. I tested the coil solenoid and I have continuity on both solenoids. Any suggestions? Thanks in advance!
I believe the coils need to be tested for resistance, I had to change my coils fairly recently and also posted a video, it’s also an easy swap and the parts are cheap. Good luck.
@MattsGarageMiscDIY checked for resistance and they have resistance. I ordered more and will be installing them today. Any other possibilities? Thanks for the reply!
@@CustomMercuryCougar I hope those new solenoid coils worked for you, less likes culprits could be the actual gas valve, or the igniter.
It ended up being the coils! Thank goodness. Was running out of options there. Happy wife, time to crack open a beer! Thanks for your help
@@CustomMercuryCougar awesome, well done, beer well deserved :)
if you have gas stove and/or a/c furnace..etc in your home be sure you have working carbon monoxide detectors and of course smoke detectors too
I did change the fuse however it didn't fire up. What else can it be?
Elizabeth, was the old fuse bad? Another fairly common issue with no heat can be the gas solenoids. Test yours before replacing them. There are some good RUclips videos that demo how to test yours for proper resistance. They are also inexpensive and easy to reach on most models. Best of luck!
@@MattsGarageMiscDIY usually the thermal fuse fixes the problem But not this time my electric dryer didn't fire up. So I am guessing at this point it could be the heating element 🤔. What size nut driver should I use to remove the heating element
Elizabeth, sorry I’ve only worked on Gas Dryers, never an electric model. Are there no good videos? I have no idea on the nut size for the heating element. Best of luck, maybe you can capture some video and share with others that have the same issue on their electric dryer!
*****HELP*****
I just changed the Thermal Fuse and ran into the same issue getting the leads off the old thermal fuse. The right one I felt didn't click on the new thermal fuse as well as it was on the old fuse. Anyway I buttoned everything up and started the dryer and now I'm getting Error Code L2 (mine is not gas btw) which I wasn't getting previous to this project. I didn't wait to see if the dryer got hot or not. I turned it off, unplugged it and came here to the comment section. Btw I did check my electrical panel and I didn't blow a breaker.
How did you remove the connectors on the thermal fuse??
Gripping the connector only and gently rocked them a little while pulling. You do want to be careful not to rip a wire out of the connector (by simply pulling on the wire)
@@MattsGarageMiscDIY THANK YOU!!! It was sooo stressful trying .. I thought I’d break it lol.. but this video saved me a few hundred dollars!!! Again.. THANK YOU FOR THIS VIDEO!!
Wait wait wait…why is that dryer plugged in to an outlet that isn’t made for appliances? Very dangerous.
I think you may be suggesting I install a GFCI outlet which is not a bad idea.
gas dryer only requires 120v to operate, not a 240v plug like an electric dryer or stove
Hope that 110v plug wasn’t your dryer plug. 🤦♂️
