Question:

Dryer is turning off prematurely. I input my model number into the website to see what might be the problem and it looked like it could be the cycling thermostat (thermostat internal bias part # wp3387134) . However, i do not see that part in my dryer. Instead, i see the high limit thermostat and fuse cut-off. Is there a cycling thermostat and a high limit thermostat in this unit, and if so, where exactly is the cycling thermostat located?

David for model number 110.67902791
Answer:

Hi David, Thank you for the question. The cycling thermostat is attached to the blower housing. Hope this helps!

Question:

I found the cycling thermostat on the blower housing just where you said it would be. However, even after removing the lint trap and lint trap housing, the cycling thermostat is pretty tightly pinned between the blower housing and the upper drum. Do i have to remove the blower housing just to get to the cycling thermostat? If so, i may have to turn this over to a professional.

Answer:

Hi David, Thank you for your question. You usually do not have to. We do have an installation video for this kit: https://youtu.be/scgftb8_06c . If you need to remove the blower however, you may have to contact a technician to help you. I hope that helps. Good luck with your repair.

Question:

I have a Kenmore dryer and the heating element would stay on even after the dryer shut off and now it doesnt heat at all. Could it need a heating element and thermostat? Im not sure if i want to tackle the job or not but i love this dryer. Thank you! Diane

Diane
Answer:

Hello Diane, thank you for contacting us. This could be from a bad heating element, if it has shorted out it could keep creating heat. You can inspect the element to see if it is broken and welded to the housing/ground. Good luck with the repair!

Question:

Mr Whirlpool electric dryer clothes coming out are extremely hot where they are burning me when i take them out of the dryer. I am confused on which part i may need. One part includes the thermal cut off kit that includes both of these 2 parts a 250 degree high limit thermostat and a thermal cut off fuse limit 360 degrees. The other part i am thinking i may need is the cycling thermostat limit 135/155. If you can lead me in the right direction, i would appreciate it.

David for model number LE5600XSW0
Answer:

Hi David, Thank you for your question. I would actually suggest testing all of your thermostats with a multimeter to see if they are all working correctly. I hope that helps. Good luck with your repair.

Dryer wouldn't heat.

I removed the back panel and tested the Thermal Fuse, the Thermostat and the Heating Element with a meter. The Thermal Fuse gave a bad reading. I proceeded to clean the dryer and lint pipe of all lent. I installed the new Thermal Fuse and put the back panel back on the dryer. The dryer worked for two loads of clothes and the Thermal Fuse blow again. I'm now at the end of my rope. I don't know what else to check and I can't continue to buy parts for only two loads. I guess I will have to invest in a new dryer.

First taking too long to dry, then no heat at all.

Unplug the machine. Take off back panel and remove heater assembly. Since I was already into the heating system, I replaced the heating element as well ($30). I replaced the old thermal cut off and overtemp, put the wires back on the connectors, reassembled, and the dryer works like it did when brand new! Within 30 minutes the repair was completed. Still saving for a new front loader washer/dryer, so the repair will hold us until we have enough to buy new. Alos, helped us to need to dry clothes on a clothes rack in the house. Good practice and lesson for the entire family!

Gas flame would shut off after + or - two minutes

the igniter worked so replaced the two coils on the burner, did not help, read the diagram that came with the machine and replace the high limit cut out. that did it, however the mounting bracket needed to be modified by grinding a tab off, so that the cut off switch would fit in to the bracket.

Dryer ran but without heat.

Turned off my circuit breaker first. Removed back panel with a 1/4 nut driver. Replaced the dryer fuse first. Very easy but did not fix the problem. Watched how to videos to narrow down the parts I might need. Purchased the thermal cut off kit. Installed the High limit thermostat first. Tested the dryer, no dice. Finally installed the Thermal cutoff. BAM!! I have heat. Since this is an older dryer I did need to use some WD40 to loosen some of the connections. Total cost of parts including tax and quick delivery was $48.30. Fantastic. My old man told me it was unfixable. He was wrong. I WIN. This site is a great teaching site. Thank you!

Dryer ran good but would not heat.

The big problem I had with this project is having the parts delivered after they were shipped from seller.Cut power off. Removed the rear access panel. Labeled wires for proper replacement. Removed wires from Thermal cut off fuses. Removed the lint screen. Removed 2 retaining screws from lint track. Raised top cover. Removed retaining bracket screw. Removed Heating Element Box. Removed one screw from bottom of heating element. Removed defective heating element. Installed new heating element using one screw on the bottom. Located element box back in position. Attached retaining bracket and screw in the top of element box. Closed top cover. Replaced lint track retaining screws. Reconnected all wires in proper locations. Replaced rear access screws. Return power to dryer. Turned dryer on and it instantly started blowing hot air out of the exhaust. Dryer is in service as of this time.

Dryer blew cold air

After removing the exhaust pipe and clamp, I unscrewed the back panel with a 1/4 inch drive socket set. That exposed the wires and the wiring skematic. I used a multimeter to track the power to the element and found that no power was reaching the element. I then unplogged the unit removing all power and tested the resistance on each thermal fuse. The lower fuse had no resistance and the upper fuse did. I then disconnected the upper fuse, used a jumper wire the connect both wires together to bi-passed the fuse. I reconnected the power and turned on the dryer. The dryer element worked, confirming my suspicions of the bad fuse. Once I ordered the fuse and only paid for regular delivery I had the fuse with 24 hours and dryer back together within very little time. It took me more time to clean up the lint dust then it did to fix the problem.

The dryer would not heat up.

Tested the two thermostats, thermal fuse and the hi limit cut off for conductivity. The hi limit tested open. The others tested closed. Replaced the hi limit. Cleaned lint from the lint duct assembly after removing the two hex head screws that hold the assembly to the blower housing. The lint was packed in there solid. Cleaned up all around. Reassembled everything. Looks and works like brand new. Access was completely from the front panel. CAUTION: The rear panel is spot welded on although it has eight or nine hex head screws also, and when you remove them, the holes don't line up for replacing them. Took a lot of head scratching and time to get things lined up so the screws would go back in again. Don't try to remove the rear panel like the video shows.
