Product Description

The internal-bias thermostat, also know as a thermistor, is used to prevent the dryer from overheating. It does this by monitoring and controlling the temperature of the inside of the dryer drum. If your dryer is overheating, not drying your clothes properly, or is not providing enough heat, there could be an issue with the thermostat. You can test the part by using a multimeter, which should read 10,000 ohms of resistance at room temperature, give or take a 10 percent fluctuation. If your reading is not in that range, the thermistor will need to be replaced. Replacing this part is a simple repair, but to access it you will need to lift the main top on your dryer, and remove both the front panel and the bulkhead. The part is found next to the thermal fuse, on the blower housing. Be sure to disconnect the power supply to your dryer before beginning this repair. This is a genuine OEM thermistor, made of white plastic and is sold individually.

I need to replace the Thermo Stat on my Maytag Dryer and looking over the internet I saw video for disassembly of the front of the dryer and a different one showing installation on the back of the unit. Can you tell which is the right one? Thanks

The dryer does not work when set on normal setting. It shuts off before the run time is complete and the clothes are not dry. It does not have this problem when using any other settings. What part do I need to fix this?
For model number Medb835dw3
Fix.com logo
Hello Faith, thank you for reaching out. According to our research, the issue seems to be with the Moisture Sensor and you may need to replace it, the part number is FIX12348005. It monitors the clothing's moisture level and sends a signal to the control board when the clothes are dry. If that does not help, we would suggest checking the Thermostat, part number FIX11746740. We hope this sorts out your problem!

My dryer would turn on and once I would hit start, it would immediately turn off. Now it won’t turn on at all. I’ve replaced the internal-bias thermostat and it still will not turn on. I’ve also turned of the breaker to make sure that wasn’t off.
For model number WED8500DW4

Hello Ginger, thank you for contacting us. A blown thermal fuse does not allow the dryer to start its operation. Use a multimeter to check if the thermal fuse has continuity. If the thermal fuse, part number FIX11766766, does not have continuity replace it. We hope this helps.

Dryer would run, but not heat
Needed it running quick, so no diagnostics. Ordered one of everything that could fix problem (plus a new door catch). Tipped it onto it's back & popped the bottom cover off. Element, thermal cutoff, thermistor, and fuse. were right in front and held by 2 screws each (don't drop them, don't ask). A little bit tight inside, but no big issu e. vacuumed the inside, replaced everything (it was the Heating Element, by the way), slapped the cover on, and put it back in its spot. works like it was new. Yes, I unplugged it first. Remember! Safety Third!

the dryer got to hot.
dryer got to hot and shut off with an Error message "E1". Found this site after many. Better explanations and half the price for the part verses Sears. I had watched Sears Tech. Tear down the machine before so i had a pretty good idea how to do it. Takes two people, just for that extra hand to hold things. The Electrical connection clips were kind of tricky to undo. So far so good. Good luck.

dryer blow fuse, was running hot
replaced the above items, dryer worked but did not solve the problem of running hot on all settings, replaced the temp gauge, did not solve the problem. Realized it was probably the electronic control assy. Decided to replace the dryer given this one's age and the ability to get a new one for about $400. Parts sent were correct. I sho uld have checked the continuity of the parts prior to buying the new ones. Probably only needed a fuse.

inconsistant drying.
There are two sensors located on the top of the blower housing. The one with an ohm reading or no reading is the thermistor. Simply replace it.

Would not dry clothes completely in any setting.
As this site recommends the parts that would be needed to fix the problem, it recommends the most likely to the least likely. Of course I bought the least likely and proceeded to buy all parts up the the most likely. All though I only spent about $100.00 total, it was the most likely that fixed the problem. The fixes were fairly easy to do and were all made from the front side of the unit. Not much space to work in but made all the fixes with out issues. Unit seems to be running well. Glad I did it myself, would do it again!

Error code E -1, Dryer would stop after 2 minutes.
Unplug. Removed the lower front panel. Locate identical part inside of Dryer. Used correct socket to break free the two screws. Removed the old Thermistor. Removed wires from old part replaced wires. Replace with new Thermistor, install two screws. Re install front panel. Plug in Dryer. Saved several hundred dollars as Dryer works great o nce again! Thanks, it took me longer to research the cause than to replace the part!
