Question:

My dryer is having trouble heating up, or heating at all. Based on what your site is saying it may be the thermostat with the thermal fuse. Does that sound right, and is this what I need to make the repair?

Question:

I am getting no heat but i have continuity and the heating coils have voltage.

Micha
Answer:

Hi Micha, we recommend first disconnecting the wires to the heater and checking them for 240 volts across both. If you do not have the 240, you need to find where you are losing the rest. I hope this helps.

Question:

What is wiring order for this repair?

Jonathan
Answer:

Hello Jonathan, the order of the wiring from your motor should go to the heater, then to the thermal cut off, and from there to the high limit, and then to the timer. Please let us know if you have any further questions.

Question:

Dryer runs, but no heat have tested everything? I am getting 240 at back of machine but only about 5-8 at wires going into heater coil. Any ideas? All other components have continuity. Am i testing correctly for voltage to heater coil?

David for model number AED4475TQ1
Answer:

Hello David, thank you for contacting us. It may not be the heating element. There is a High-Limit Thermostat and an Operating Thermostat. If either of these are faulty they can cause the heating element to not heat up. They can be tested as well with a multimeter. Hope this helps!

Question:

My dryer won't dry clothes, and it runs continually, i am wondering if it would be a thermostat or the heating element? How would i go about diagnosing the problem? Thank you!

Wacey for model number Kenmore model # 11096561230
Answer:

Hello Wacey, that is a great question. It is possible that it would be on of the thermostats, you can test these with a multi-meter, as well as the heating element to determine which is at fault. Hope this help!

Question:

Hello. For the past two weeks when running my dryer it shuts off after 5 mins. As of 08-21-17 it will not turning on at all. Could this part fix this issue? Thank you in advance.

Dion for model number GEQ8858EQ0
Answer:

Hi Dion, Thank you for the great question. The first part we suggest you replace is the Thermal Fuse. This thermal fuse is designed for use in dryers. It is a safety mechanism that stops the flow of electricity to the heating element when a dryer overheats. When this fuse is faulty, your dryer will not start or it will not heat properly and shuts off to soon. This is a one-time fuse, meaning it cannot be re-set, It must be replaced. Hope this helps!

Question:

The dryer shuts off by itself at various times. Sometimes it will go the whole cycle, but most often will shut down with in a few minutes. It will shut down in any cycle, (heat or no heat, time dry or automatic). When restarted it may run the whole cycle even if it where immediately restarted. It's more likely to shut down early with a load than when empty and the motor appears to work perfectly (no detectable draw on motor and it runs smoothly). Is it possible the door switch could malfunction like this?

Walt for model number WED4800BQ1
Answer:

Hi Walt, Thank you for your inquiry. If your dryer is shutting off just shortly after it is turned on the parts you will need to look at are the thermal fuse, the drive motor, the timer, the door switch, the door strike and the door catch. I hope this helps. Thank you and have a great day!

Question:

Dryer produces no heat on the low setting. High settings seem ok. Are there separate coils in the heating element for the low setting? On low, none of the elements heat up. On high, some do.

Steve for model number RED4440VQ1
Answer:

Hello Steve, thank you for contacting us. These could be caused from a faulty thermostat or heating element. You can test these parts with a multi-meter to determine which is at fault. Hope this helps!

Question:

The clip at the end of the heating coil that goes through the ceramic insert that attaches to the heat thermostat 105/3086 on the bottom of the heat box has burned and broken off need to replace the clip that goes through the ceramic part that is crimped onto the end of heating coil. Also why would this clip look like its been welded and disintegrated off

Rick Grenier for model number 11066862501
Answer:

Hi Rick, Thank you for the question, the clip is not sold separately from the heating element so the heating element will need to be replaced. I can not say why the clip become defective and burnt off or looks welded , it could have been a defect in the clip. Hope this helps!

Question:

No matter what temperature selection i put on the temp control it always puts out maximum heat. Readings on w/blu and w/pur contacts change from infinite, 0.3, 1.3k, 2.5k and infinite ohms when cycling through the settings from air only to high heavy respectively.

Tony for model number WED5300VW0 clothes dryer
Answer:

Hello Tony, thank you for contacting us. The heating element would be more common for over heating. If the element is partially shorted out, it may produce heat continuously, even if the dryer has reached the proper temperature. When this happens, the dryer gets too hot. To determine if the heating element is at fault, use a multimeter to test each terminal for continuity to the case. If the heating element has continuity to the case, it is shorted out. Hope this helps!

Question:

Iv been working on this two times,, first , the dryer didn't have heat, i checked the e!Cement, yep it was broke, put a new one in, worked for a week, then the dryer stopped running, the thermal fuse broke, replaced it, but,,, now i find the heat is extremely hot, from all three settings, cool to hot, is it the reostat switch temp switch, or the extreme temp switch, or others ,, i don't want to have to replace any thing iv already done,,,, the exhaust tubes are cleaned, and work fine,, thanks for info!!!

Steve for model number TEDS840PQ
Answer:

Hi Steve, Thank you for your inquiry. The majority of the time the part to replace if the dryer is too hot is the internal bias thermostat, part number PS11741405. The second most common part to fix the issue is the thermal cut-off kit, part number PS334299. I would check both parts with a multimeter to verify which one is causing the issue. I hope this helps. Thank you and have a great day!

Question:

When reconnecting the wires to the cutoff part on the heating element as well as adjacent parts does it matter which terminal the 2 wires going to each part are connected to?

Don
Answer:

Hi Don, Thank you for your inquiry. Yes, I believe that it does matter. For the thermostat that is at the bottom near the heating element prongs, the jumper wire is supposed to connect to the left hand side element prong and the bottom prong of the thermostat. For the thermal fuse, you should have two wires separated by a strap that holds the whole harness together. The top wire should snap into the top prong of the fuse, and the wire underneath the strap snaps into the bottom prong of your fuse. I hope that helps. Good luck with your repair.

Dryer wouldn't heat

I shorted the thermal cutout after removing the back.
I then ordered the thermal Cut-Off Kit from PartSelect.
While this was not my first order from them, I was still impressed with the ease and by how soon I received the part without any hassles or glitches. PartSelect will be my primary parts supplier from now on.

The dryer wouldn't heat at all.

I read troubleshooting tips from other users of this website. This website had all the information I needed to accomplish the repair.

I unplugged the dryer, then tipped it onto its front. I then used a nut driver to remove the dryer backing. After removing the dryer backing, I used the same nut driver to remove the heating element cover since it was the part I initially suspected. The same size nut driver worked on all the parts.

Per recommendations I read on the site, the first thing I did was a continuity check on the heating element. It was good. After reviewing some input from this site, the next best step seemed to be replacing the Cycling Thermostat. I ordered and installed it, but it didn't fix the problem. The cool thing? PartSelect.com got me the part within a couple of days. So, I came back to PartsSelect.com and ordered the next two cheapest parts (ordered two parts at once to save on shipping and handling). The parts came within 4 days. I used the Thermal Cut-Off Kit in its entirety and the problem was fixed! THANK YOU PARTSSELECT.

Here's an impact statement: The day after the dryer had stopped working, I called a repair shop. They told me that if they came out that day, the cost would be $85, plus parts, plus labor. I figured that would run around $140 - $150. Total for PartSelect.com? Around $60 (including shipping and handling) -- and I didn't even use all the parts I ordered.

Dryer not heating, but motor running

I first unplugged the dryer and pulled it away from the wall. I had to remove the vent tubing to gain access to the rear of the unit, then removed the screws on the back panel of the dryer. I took off the panel and noticed that lint that had gathered over the years around the back of the dryer. I vacuumed it clean then proceeded to problem solve. I noticed four easily identifiable areas, the thermal cut-off switch and thermostat located by the heating coil and the thermostat and fuse near the venting area. I first checked the fuse with a ohm meter, it was okay. I removed each component one at a time and created a bypass with a alligator clip wire. Plugged the dryer back in to determine if heat was produced while testing each area one at a time. I determined that heat was produced after bypassing the thermal cut-off switch. I then ordered the thermal cut-off switch kit (arrived within 3 days) and installed it within 20 minutes. The longest time spent was trouble shooting, the removal and installation was very easy. By the way, I did use the ohm meter to check the resistance across the thermostats as indicated in previous postings, but I found the results and technique to be more confusing. A bypass worked the best for me and much more reliable. The heat started immediately. I highly recommend downloading the schematics of your unit for part number and location identification.

No heat in the dryer

Initially I incorrectly diagnosed the problem... Make sure to test the continuity in all thermostats and heating element to identify which part is not working. Easiest way is to use a meter with an audible ohm continuity setting. Test the continuity on all thermostats/fuses, and element. If there is no continuity chances are that is it.
Good luck!

Would not start

The repair itself was easy however testing the components was not easy. I first just guessed and replaced the start switch. when that did not work I did some more research and bought a multimeter. I did not buy a meter that tested for continuity so I did more research and found that if I set it on ohms and if the meter went to 0 the component is good if it went to anything else the component is bad. Any way I bought the thermal fuse and the thermostat kit. the part for the fuse was correct but only 1 thermostat in the kit I bought was correct. as soon as I put the fuse in the dryer immiediately started.I know it is reccommended to replace the thermostat too even if it reads good because it could be going bad but I left the old one in because even after opening the door with the timer on the heating element would stay on with the new thermostat so I was aprehensive about leaving the new one in and took it out and put the old one back. well two days later the dryer would not start again. I have tested all of the thermostats and they are all good except the one so I replaced it with one I got in the kit and had to order a new thermal fuse. I am hopping that I will get it right this time. I am into this repair about 80 dollars 1 new start switch I did not need 10$. the thermostat kit 20$ and I only used 1 out of the 2 because the second one is not compatible. 2 thermal fuses now 20$ A multimeter 20$. plus shipping costs. I still feel like I have saved 75 to 100 dollars and now I know more about how to repair a dryer. I think that once I get the new fuse It will start. I hope this helps all of those out there trying to save a dollar. I recommend buying a multimeter that tests for continuity so that you can test all of the components with ease. It is hard to be sure about what you are testing and trust what yourself after reading the information on line. If I had to do this over again I would have just bought the 1 thermostat I needed and the fuse and trusted that I really needed to replace that stat because putting that dryer vent back on is going to worse than the repair. Good luck to all.

No heat to dryer

PartSelect website was hugely helpful. The diagram of the dryer was great. I determined my thermal cut-off switch was bad. The part was ordered and arrived in a couple days. It was very easy to change. If your thermal cut off is tripped, don't forget to clean your entire duct work, it is most likely blocked or restricted.

My original problem was due to a blocked/ broken vent tube, which lead to the failure of the thermal cutoff switch.
