A cycling thermostat is in tune with the temperature of your dryer and regulates it in order to maintain a certain temperature. This thermostat reaches a temperature of 155 degrees and will then turn off and then on again once it has dropped by 25 degrees. If your dryer is not giving off enough heat, is over-heating, is not turning on, or is having issues with the timer functionality, this could indicate an issue with the thermostat. The installation of the cycling thermostat is simple and the only tool required is a 1/4 inch nut driver (and gloves for safety).

This part works with the following brands: Whirlpool, Kenmore, Maytag, KitchenAid, Roper, Estate, Crosley, Inglis, Amana, Admiral, Magic Chef, Jenn-Air.

Question:

I’m not sure how often this happens because it hasn’t happened to me or anyone I know before. But our dryer seems to be getting too hot during cycles. The clothes are way too hot when they come out, even on the lower settings. The heater element is still cycling on and off though which is think is normal. I’ve already checked the flow and the vents and everything seems to be square there. What would you recommend I check next. Do you think it’s the thermostat?

Kealan
Answer:

Hi Kealan, we recommend trying to dry a load with the vent unhooked from your dryer. If you are still experiencing these symptoms you could have a faulty dryer cycling thermostat WP3387134. I hope this helps!

Question:

My dryer is turning on and “working” but it is not heating properly. It is a gas dryer and it doesn’t seem to have a problem igniting. What should I check?

Leo
Answer:

Hi Leo, we recommend testing the coils 279834 to see if they are faulty. You can test them using a multi-meter tool. Please let us know if you have any further questions.

Question:

My dryer is taking too long to dry the clothes in it and I am not over filling it. My friend suggested a blockage but we already checked for that. We also tried using the different settings and the only one that seems to be buggy and not working is the highest setting. So do you have any suggestions of parts to check or tests to try to fix this.

Dylan
Answer:

Hi Dylan, we recommend testing the temperature coming from the dryer when on high heat, which should be about 110 (low end) to 160 (high end) degrees. If your dryer is cycling before it hits the 150 degrees, you most likely have a faulty cycling thermostat. This can be tested with a multi-meter with temperature. Best of luck with this repair!

Question:

Is there a way to test the thermal interna bias switch to be sure it is the problem

Jerry for model number Ler7646ez2
Answer:

Hello Jerry, thank you for contacting us. With a multimeter you can test the two large terminals on the thermostat, they should read closed for continuity and the two small ones should show an ohms resistance value. We hope this helps and good luck with the repair!

Question:

None of the components are testing bad. ? The thermal fuse, the high temp sensors, start switch, door switch, all are showing continuity or resistance. The heating element is good. I have only 2 choices left. The timer or the motor. The motor is last as it is hard to get to. The problems began when the timed dry cycle quit heating as it ran. So i used the auto-sense cycle and it worked great. Problem solved for 6 months. Yesterday i put the clothes in and set the timer and pushed start. Nothing! No hum, no buzz, nothing. Not on any cycle. Both parts left are expensive. So, is there a go, no go test for the motor? Would you be inclined to suspect the timer? How can i be sure it is one or the other? Thank you for the help.

Danny for model number EED4400WQ0
Answer:

Hello Danny, thank you for contacting us. It does not sound like an issue with the motor. It sounds like it would be the timer. The dryer timer is used to control the unit's cycles by regulating the length of time that power is directed to each setting. If it becomes faulty it could cause nothing to happen when you start a cycle or only work on certain cycles. Hope this helps!

Question:

I have a KitchenAid dryer that has stopped heating. I have checked thermal fuse and it shows conductivity. I checked the thermostat with a multi meter and the two red wires(large post) show conductivity but the two purple wires(small post) do not show any conductivity. This was done with the power cord unplugged. Are both the large and small post suppose to show conductivity?

paul for model number KEYE760WWH1
Answer:

Hi Paul, Thank you for the question.The two large terminals on the thermostat should read closed for continuity and the two small ones should show an ohms resistance value. We hope this helps and good luck with the repair!

Question:

My dryer is taking forever to dry, usually 80-90 minutes for a regular size load. It seems to get hot, but I'm not sure if it is shutting off too soon. I replaced the internal bias thermostat, but it's still not drying properly. I have also checked for blockages and cleaned the back of the dryer and the vent system as well. What part would likely need to be replaced next? Thanks!

Brandy for model number WED5100VQ1
Answer:

Hi Brandy, Thank you for the question. If the appliance is still getting heat but not drying in the proper amount of time you might not be getting enough heat. I suggest testing the element with a multi meter. PartSelect Number PS334313. The element should test between 9-12 ohms. If the you do not get the reading between 9-12 ohms then you have a defective element.If you check for continuity the meter will beep, if you do not get a beep then the element is defective. Hope this helps!

Question:

My dryer doesn't heat up. I replace the thermal fuse and it still doesn't get hot. So what is the problem?

Rene for model number LGR4634EQ3
Answer:

Hi Rene, Thank you for your question. There are a couple of parts that could cause the issue. I would suggest checking your m series coils, thermostats, radiant flame sensor, and your igniter. You can test all of those parts with a multimeter. I hope that helps. Good luck with your repair.

Question:

My dryer cycles between 120 and 160f no matter what the temperature selection (high, medium or low). If I stick wires into the back of the temperature switch connector (contact with the only 2 wires violet and blue going to the switch) I measure 0.0 ohms for low, 6,200 ohms for medium (same resistance as the resistor jumped in), and infinite resistance for high heat. The wiring diagram says the resistance should be 10 ohms Max for low heat and 10,000 ohms min for high, so I think it is working. The internal bias thermostat reads 0 ohms across the big leads and 7,100 ohms across the small, which I believe indicate it is fine. What should I do now?

Roger for model number WED4800XQ1
Answer:

Hi Roger, Thank you for the question, I suggest checking the Thermal Cut-Off Kit,PartSelect Number PS334299.This dryer thermal cut-off kit includes one high-limit thermostat with a limit of 250 degrees Fahrenheit, and one thermal cut-off fuse (309 degrees).The thermal cut off turns off the heating component when the dryer overheats, ensuring there is a consistent level of heat at all times. Hope this helps!

Question:

This dryer works the whole cycle, but still the cloths are wet and cold. No heat. One time this had happened I had replaced fuse.

Abe for model number WED5530SQ0
Answer:

Hi Abe, Thank you for the question. Sounds like you need to replace the Thermal Fuse.When this fuse is faulty, your dryer will not start or it will not heat properly. This is a one-time fuse, meaning it cannot be re-set. It must be replaced when there is no longer continuity between the terminals. Hope this helps!

Question:

Dryer stopped working. I replaced the thermal fuse. Dryer worked fine one time and stopped working again. I replaced the thermal fuse again and vacuumed the duct work inside the dryer and dryer pipe leading outside. Pipe is solid not Flex pipe. Again after one load the fuse blew. Could this be the heat sensor unit?

Jim Heinold for model number keys677ezo
Answer:

Hi Jim, Thank you for your inquiry. If your dryer is constantly blowing fuses, it sounds like an issue with a circuit breaker on your electrical box and you may have to have an electrician examine it. I hope this helps. Thank you and have a great day!

Karen for model number RED4440VQ1
Answer:

Hi Karen, Thank you for the question, This dryer timer is used to control the unit's cycles by regulating the length of time that power is directed to each setting. You will need to use a multi meter if you wish to test the timer. Hope this helps!

Question:

How do you check the timer switch,everything else checked out good. My dryer will not start.

Karen for model number RED4440VQ1
Answer:

Hello Karen, thank you for contacting us. If the dryer will not start and nothing works the most common part for that would be the thermal fuse PS11741460. 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. This is a one-time fuse, meaning it cannot be re-set. It must be replaced when there is no longer continuity between the terminals. Hope this helps!

Question:

My dryer would get too hot and overheat. I would need to turn it off to cool down and restart. We replaced the thermostat, and internal-bias and thermal cut-off kit(but my husband did not use the new red wire in the kit) dryer worked fine for a few minutes with heat and now no heat at all. Suggestions? Thanks

Tracie for model number LTE6234DQ0
Answer:

Hi Tracie, Thank you for your inquiry. If your husband did not use the red wire in the thermal cut-off kit, that may be causing the issue. I would also check the heater to see if that is working correctly as well. I hope this helps. Thank you and have a great day!

The dryer stopped heating

Accessed and removed the rear panel. I replaced the three electrical components with a nut driver and reattached the rear panel. The fix worked, so I have not yet replaced the gas coil sensors at the front of the dryer. The dryer is 19 years old, so the electrical connectors were pretty tight. I used needle nose pliers to pull the connectors free and prevent any damage to the wires. Good Luck.

Dryer would leave clothes damp

First, I unplugged the dyer and then I removed all of the screws for the panel that covers the rear of the dryer. This exposed the cycling thermostat's location. I then removed the wires, one at a time so I would be able to put them back on in the same place. Then I removed the one screw using a nut driver and then put the new cycling thermostat in place. It was pretty easy.

The dryer would not turn on and the autodry feature quit working.

First I removed the back of the dryer. Then I used a multimeter to check the thermostsats and the one time use fuse. I found that the fuse had burnt out and one of the thermostats ha checked bad. I changed the fuse by removeing the one screw and lifting the fuse out. Replaced the fuse and reinstalled. I also made sure that the fan for the dyer and the lint trap area were clean. I also changed both of the thermostats while I had the dryer apart. Reassembled the dryer. Everything worked. NICE! No repair bills or buying a new unit.

Clothes took way too long to dry (1-3 hours)

The first thing I did was google "whirlpool dryer repair drying takes too long" to determine all of the possible parts I needed to order (the result was 3 possible parts, a heating element and two different thermostats). I then went to www.partselect.com (I'm a repeat customer) and searched the parts using the dryer model number listed just inside the door. I then printed the dryer model diagram off of the www.partselect.com website to determine the location of all the parts and how to replace them. Our first purchase was the new heating element from the www.partselect.com website, received it in just a couple of days and replaced it, but that did not fix the problem. We then ordered the two thermostats, again received them in 2-3 days, replaced them, and were drying clothes in <30 min. in no time! All we had to do was unplug the dryer, disconnect the vent hose, take the back off, unscrew each thermostat, disconnect the wires, install the new thermostats, reconnect the wires, screw the thermostats back in place, replace the back cover, reconnect the vent hose and plug the dryer back in. It took <15 min. for the complete repair! Thanks, www.partselect.com! I will continue to be a repeat customer!!!!!

Customer: STEVE from JACKSONVILLE, FL

Dryer would not start. However, there was a humming throughout while plugged in.

Very easy to access all 3 parts. Was using YouTube in conjunction with video installation. Bypassed door ajar switch which is readily available via video online.. You do need to cut wires near switch end but does not affect the other side that plugs into factory connector. I figured if it works I'll just order a new one. However, it was fine. Very simple to test almost all other parts if you have a volt meter to check resistance. There was too many prongs to test pushbutton start switch so I ordered one and a thermostat. Parts arrived in a few days. I also ordered a new door ajar switch incase one of the other reasonably priced parts fixed it. I first replaced the push start switch which was very easy. It did not fix my issue. So I than replaced the thermostat. Even though it was very uncommon to fail according to the %of people having that as a cure, it fixed mine. So since the start switch was not returnable because I opened bag and installed it, I left it in and saved the old one. Since it was fixed I went ahead and replaced the door ajar switch instead of leaving it Bypassed. All in all...took no more than 1 1/2 hours and that includes testing everything opening up everything and putting everything back together. Very easy.
