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 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!

Timer won't advance for auto-sensing cycles. Low Heat.
First I unplugged the dryer from the wall outlet. Then, removed the access panel in the lower front (held on by 2 screws near the floor). Then, I removed the black plastic air duct (held by 3 screws) in front of the blower. Then, with a Sharpie marker, next to each wire terminal lug, I labeled on the chassis the COLOR of each wire where it plugs on to a terminal lug (for proper wiring re-assembly later). Then, thru the lower front, I reached into the lower left rear of the dryer to remove the heating element assembly from its metal duct (held by 3 or 4 screws) - it slides down a bit, then it is easily removable. I layed the element on the floor in front of the dryer - all wiring still intact. Then, using the NEW HEATING ELEMENT and SENSORS ordered, I assembled them to match the original, re-using screws off of the old unit - and moving the wiring one-by-one from the original to the new assembly. I then installed the new heating element assembly into the duct at the lower rear of the dryer. I then replaced the 2 sensors on the front metal panel of blower housing, with new parts from my order, re-using the original wiring and screws. Then I re-installed the black plastic duct onto the front of the blower. Then, on the top of the dryer, I dissassembled the control panel from the rear, by removing 5 screws. I then found the resistor mounted on the back of the timer, and replaced it with the new one. Since the new resistor did not come with terminal lugs crimped on its wires, I had to cut the terminal lugs off of the original resistor and solder them onto the new resistor. I then reassembled the control panel. I then plugged the dryer back into the wall outlet and did a test run with no clothes. IT WORKED !! Then I reinstalled the lower front access panel and ran the dryer with wet clothes. IT WORKED !!
Replaced heating element, which had a fuse and high limit thermostat attached to it. Remove 2 screws to pull the bottom cover plate on the dryer, remove 3 screws to pull the blower inlet shroud and then remove 2 screws to pull the heating element off the air inlet duct at the back of the dryer. Remove 2 screws each for the thermostat and fuse. Installed the new devices back onto the new heating element. Power leads to the element are long so you can pull the whole thing out very easily. Couldn't have been any easier to fix.
removed front cover and top took drum out remove heating unit replced limit switch and fuse reinstalled installed new idler put new belt around drum installed drum replaced glides put top back on and front cover . then replaced boosting heater witch is on the blower also cycling thermostat
This dryer required complete take apart to get to heating element, including removal of drum. Multimeter indicated thermal fuse blown. I replaced it and it blew again. I replaced fuse(again), heating element, limit thermostat, and cycling thermostat to eliminate all potential causes. Dryer works like new. Cycling thermostat had been bad for years, but I never knew it, just had to run dryer two cycles all the time.
I opened the front panel and removed the heating element from the rear of the dryer by removing the two screws that held it in place, and slid the element out. using a mulitester I checked the High limit Fuse and it was not working.I ordered the part and replaced it. Everything worked great for two days and the dryer stopped heating again. My brother asked if I had replaced the thermostat because something burned out the fuse. He was right. I ordered both parts and replaced them. Every thing is working just fine. Save some money and time by replacing both parts at the same time.
Remove 2 screws on the front panel at the bottom of the dryer & remove front panel. Remove the black plastic "duct" from blower to lint filter by removing 3 screws. Heating element is on the back wall of the dryer in the lower left corner. 2 screws hold the heating element to the dryer wall. Remove these 2 screws. Might be a little tight to get back there. Try to be more patient than me. :) The wires on the heating element are plenty long enough to bring to the front & outside of the dryer. Remove screws holding thermostat & fuse to heating element. I wasn't sure if I needed a new thermostat or not, but it wasn't expensive so I went ahead & decided to put a new thermostat on the new heating element. I re-used the fuse from the old element, but they're not expensive either. Just notice how rthe thermostat and fuse are oriented on the old element & put them on the new element in the same orientation. I had to use pliers to get the wires off the old element's terminals. They were a little tricky to get off, but my dryer is over 10 years old. They've been on there a while. Just move 1 wire from old element to new element at a time. That way you don't have as much of a chance hooking up the wires wrong. Put new element in & everything back together. I vacuumed out the lint in the bottom of the dryer. I ran the dryer for over 30 minutes with no clothes in it to break the new heating element in. You're good to go! You CAN do this yourself. It's not a hard repair to do. Don't buy a new dryer or pay an appliance repair guy! Thanks to PartSelect for quick delivery & posting these instructions from other people!!
removed lower front panel, two screws on bottom edge. Limit thermostat located on lower portion of vertical panel at rear of dryer. I was able to detach the two wires and removed the two thermostate retention screws with a nut driver. Since I could only operate with one hand, I taped the new thermostat in place lining up the screw holes in order to replace the two hex screws. reattached the two wires and front panel.

Dryer would not heat
First I turned off the circuit breaker, then removed the two screws that hold the front lower panel in place. Once open I removed the 2 screws that held the element in place. (Far back left side) I then pulled the element out leaving all wires connected. Wires are long enough to extend out to the floor in front of the dryer. I simply exchanged the wires one at a time to the new element so no mistakes could be made. Reinstall, reset the breaker, and Instant HEAT. Repaired for under $40.00
