This hi-limit thermostat acts as a safety mechanism that keeps the dryer from overheating. With this thermostat, a dryer's heating element will cut out if the internal temperature reaches 225 degrees Fahrenheit. The element will kick back in when the temperature drops to 185 degrees Fahrenheit - the differential of 40 degrees.

Dryer would not stay running
Using instructions from your website, I was able to remove access covers from my driver & find the pieces that needed to be replaced. It was a simple repair job & now my dryer is working properly again.
After taken apart to replace high limit thermostat fuse and limit thermostat took about 5 minutes. Also our dryer always ran very hot no matter what setting it was on. Replaced idler pulley wheel also because seemed not to rotate very well. Put all back together and worked perfect. Ran and does not overheat now.
I dismantled the dryer and replaced the thermostat and the heating element. The online videos are excellent. Thanks

Excessively long time to dry clothes
Removed lower panel 2 screws, removed blower vent housing 3 screws,reached in to lower left back wall and removed 2 screws and removed the heating element,wires were long enough to reach the front. Replaced thermostat and element and re installed.The vent was loaded with lint .The dryer works like new. Really easy
My problem was that my AMANA dryer would not heat. The site suggested testing the two thermostats so I opened the dryer but didn’t follow the instructions in the video tutorial on the site since my AMANA is different. I used a nut driver and needle-nosed pliers for the whole job. Here’s what I did:
1. Unplugged the dryer.
... Read more 2. Disconnected the exhaust pipe at the dryer.
3. Pulled dryer away from back wall about two feet.
4. Removed the two bottom panel screws (floor level) and removed panel.
5. Removed the two door panel screws and removed door panel by pulling out at the bottom until the two spring clips released from the top panel.
6. Noted the colors of the wires going to the door switch and removed (green, black and white from left to right).
7. Noted the colors of the wires going to the lamp and removed (bottom - black and top - red.)
8. Removed the two top panel screws, lifted up the top panel and leaned it against a support.
9. Removed the four bulkhead screws and carefully lifted up and removed the bulkhead being sure to support the drum. Took note of the belt path around the motor and idler pulleys.
10. Reached under the drum and took the belt off the idler pulley and motor drive pulley.
11. Used the belt to lift and remove the drum through the front opening.
I noticed that the internal vent pipe had become disconnected (which probably caused internal overheating) so I fixed that.
I then removed the wires to the thermostats and tested both for continuity. The limit thermostat was bad. I also saw that the belt was becoming cracked. I ordered a new limit thermostat and belt.
Installation of the new parts was a snap. I removed the old thermostat with the nut driver and replaced with the new one and pushed the wire connectors back on. Replacing the belt was a little trickier but not a problem. (Be sure to route the new belt correctly as noted on Step 9 and place ribbed surface next to drum.)
I closed up the dryer by reversing the opening steps.
The video on the web-site was very helpful in showing how to take it apart. First we remove the power plug from the wall outlet. Then we used flat scrapper to push the top two hidden clips to release the Dryer's top. We used the nut driver to unscrew the two screws that held the front panel. We carefully remove the wires that were connec
... Read moreted to switch sensor for the door, and the lights. Next step was to unscrew couple more screws that held the front piece from the main fan housing. At the bottom locate the tensioner of the belt. Release it. Remove the dryer drum with the belt. We took the opportunity to clean off the lint that was all over on the bottom of the dryer. We then could reach the bottom left back of the dryer to unscrew the screws that held the heater unit. Before that we unscrew and release the wires for the Thermal fuse and the limit thermostat which are all located on the heating unit. Then we replace with new pieces. Upon removal of the heating unit we noticed the broken heating element. Next was to place the drum back in. We made sure that the drum lined up with the rear support piece then the front. We rotated the drum just to make sure that it was sitting correctly. Then we screwed the front housing unit. Then we put the front panel back on the hooks at the bottom. That help to line up the front panel with the main chasis. We connected all the connectors to the right terminals. Last was to set the top down on to the chasis. We checked that the duct in the rear is not obstucted. Lastly was plugging in the power cord and testing the dryer. It is working again. Thanks to Part Select's video and parts. Total time was just over half an hour.
Easy, but the directional video on the website wasnt for the dryer my daughter had. Didnt have to take all apart as directed. Should have only taken the lower cover off the front of the dryer. But, got the chance to really vacuum & clean out all the extra build up of lint that was a Major fire hazard. Turned out good in the end, Dryer he

not sure if it was the fuse or the limit thermostat because for $15 I re[laced both, just in case. quick and easy and the online video was awesome. it took longer to fit it back together than it took to take it apart and replace the componants.

Dryer will turn on start to warm up run for about 20 to 30 seconds then shut off. It will start up again when you push the button and run again then shut off a little faster. I ordered two parts a high limit thermal fuse and a limit thermostat hoping this will fix the problem.
For model number MDE4658AYW
Hi Stephen,
Thank you for your inquiry. where the dryer is shutting off too soon, there are a few parts that you will need to check. The high limit thermal fuse and the high limit thermostat are 2 of the parts that fix the issue and the fuse is the part fixes the issue the majority of the time. If these 2 parts do not work There are some other parts that you will also need to check. You will need to check the motor assembly, the door catch kit, the electronic control board, the cycling thermostat, the door switch kit, the temperature control thermistor, the drum support roller and the belt. I hope this helps. Thank you and have a great day!

My dryer does not heat up. I set it for 90 minutes and when it stopped, the clothes were still wet and the dryer was cold.
For model number LE4207W2
Hello Judy, Thank you for your inquiry.We would recommend checking the following parts to fix your issue: 'M' Series new style coil kit, high limit thermal fuse, limit thermostat, the heating element and the cycling thermostat. You can test the parts with a multimeter. If you are unfamiliar with how a multimeter functions, there are YouTube videos available to assist you. Hope this helps!

The dryer will not start. It makes a buzzing noise when the start button is pushed. The motor starts to rotate, but it will not start. I have replaced the drum rollers, idler, and drum belt a couple of months ago and it has been working fine until now. Can you help?
For model number LEA50AW
Hello Gary,
Thanks for your question. This could be an issue with the door switch, limit thermostat, or the thermal fuse. You may wish to test them with a multimeter for electrical continuity, and replace them if they show no continuity. You may also wish to examine the door catch for any signs of wear and tear.
I hope this helps.
I asked about a wire that was burned off it’s connection but i did not get the right answer. This wire is just below the limit thermostat and it is a black wire which traces back to the motor harness. It apparently was burned off its connection and i would like to know what would cause this to burn off?
For model number Mde3757ayw
Hello Tim, thank you for your question. The most common cause of a wire burning up is the wire and/or connector starts to oxidize/corrode and becomes a resistor rather than just passing current. Try trimming the wire back to where there's clean wire and install a new terminal spade connector. I hope this helps!

I recently replace the motor the tension pulley the belt and door switch. My dryer turns and heats up but shuts off after about 30 minutes and then there is a waiting period before it is able to be turned back on. Usually 30-40 minutes before it is able to turn back on. It worked fine before I replaced the motor except for the pulley had worn out that is attached to the motor and would turn the drum any longer. I have taken apart and put back together multiple times with no change. Please help
For model number Maytag mde3706ayw
Hi Zachary, thank you for reaching out. It sounds like the motor is overheating. If it is covered with lint, it can overheat. The issue is probably due to the lint buildup on the lint filter; there can be an invisible film, maybe from the softener, that is blocking airflow. Scrub the vent with hot water and dish soap, rinse well, and then it will work. We hope this helps.

My Amana dryer shuts off too soon. When it does it is half way thru the drying cycle. I cannot start it again without waiting. (cool down?) I have cleaned the venting and I have also replaced the high limit thermostat and also the cycling thermostat. After waiting awhile I can restart the unit.
For model number NDE7800AYW
Hi Paul, Thank you for the question. I suggest testing or replacing the Limit Thermostat, PartSelect Number PS11748479.This limit thermostat acts as a safety mechanism that keeps the dryer from overheating. With this thermostat, a dryer's heating element will cut out if the internal temperature reaches 225 degrees Fahrenheit. The element will kick back in when the temperature drops to 185 degrees Fahrenheit - the differential of 40 degrees.Hope this helps!
