Our dryer won't heat. We think it might be part 42 that is the issue, since every thing else is normal. What should the resistance be on the internal bias thermostat? We have 11.4 kilohms.
For model number MEDX500XW0
Hi Grace, Thank you for your inquiry. The reading for the internal bias thermostat should read zero. If it is not zero then you will have to replace the thermostat. I hope this helps. Thank you and have a great day!

Timing is off will dry for 10 min then jump to 48 min does not turn off
For model number Wed6600vwd
Hi Joan, Thank you for the question. This sounds like an issue with the control board, PartSelect Number: PS11748076. The timer is built into the board so the board will need to be replaced. Hope this helps!

I have a Maytag dryer model mgdx600xw0, i have no heat. I replaced the igniter assembly and sensor pt# wp338906. I still have no heat. Can you help me?
For model number MGDX600XW0
Hi Rick, Thank you for the question.Sounds like the 'M' Series New Style Coil Kit, PartSelect Number PS334310 needs to be replaced.When the igniter reaches a high enough temperature, these coils work together to let the gas enter the dryer. The coils open the gas valve; if the valve does not open the heating element will not ignite. Hope this helps!

Hello, with the timer set on towels the unit has started to add time to this default setting. Other settings the timer works correctly. Thank you
For model number WED7600XW0
Hi Art, Thank you for your inquiry. That is a fairly tricky issue unfortunately. I would suggest testing your control board, this part, and your sensor as well. It could be that any one of these parts is causing that issue. I have listed those parts in two links below for you. If you find that they are all working fine, you might have to contact a repair technician to come and service your appliance. Good luck with your repair.

Dryer overheated, blew out thermal fuse
I started to repair this and got busy and ended up calling a repair service -- that was the first time. They repaired it for over $200 and said the cause was bad venting. I fixed the vent before using the fixed dryer but it blew again. So I ordered these parts and replaced them myself for a lot of savings. However, the dryer still overheated. Through lots of testing I found the root cause the repairman missed: The heating element had gotten so hot that the assembly holding it warped, hitting the element and shorting it. So a new element is on order. I still needed the parts I ordered here but the overall repair ended up more complicated and expensive. I was disappointed a paid repair person left without further diagnosis. If he had unplugged the vent and checked the heat on the exhaust vent (as I ended up doing) it would have been obvious more than a new thermal fuse/thermistor was necessary. Instead I wasted over $200 on his visit. So my advice is if you're at all handy, repair this yourself. The dryer has a service manual inside the front toe board that walks you through most diagnostics and tests. However, it took a little more than that for me to discover the heating element problem. This was a very dangerous situation that could have easily led to a fire, yet not found by a trained technician!

Dryer shuts off on any cycle except "air only"
I read in the forums that thermistor replacement fixed this issue 56% of the time. I replaced the thermistor and then ran three loads of clothes through a one-hour dring cycle at the highest temperature and the dryer did not shut off.

Dryer turns off after 1-2 minutes
I tried to follow directions followed by others on this site after diagnosing the problem via suggestions provided by users. I have a Whirlpool Duet dryer from 2002. We've had problems since moving about 3 years ago. I removed the front panel (lower) by unscrewing the two bottom screws (1/4" sheet metal screws). Then I took out the lint screen and the metal tube/contraption immediately beneath to get access to the area where thermistor is located. See the drawing/chart to help you locate this. It's really easier than it seems. Make sure you have the chart/drawing for your model - it makes difference! The thermistor came out pretty easily with a nutdriver that has a swivel offset shaft. Ask your hardware store tool dept. about that one. Put everything back in reverse order of course and test either with/without the front panel re-attached. In my case it fixed at least part of the problem. I was able to get clothes almost dry with most settings but I have yet to install the moisture sensor to see if that helps in addition to the internal-bias thermistor. I am the kind of person that does one thing at a time so at least I now know the thermistor was bad. Good luck and hang in there with your own repair. It's a lot cheaper even if it takes you longer to do than a pro.

When using the dryer the cycle would stop and display E1 as the reason
Unscrewed the bottom panelof the dryer and located the thermistor through the schematic for my machine. Removed the old one and put the new one in the same way. No more E1 problems and all cycles now complete themselves.

Switch broke and would not light the refrig compart
The repair descripition was accurate. The difficult part was getting the old switch out. It has a release clip that is hard to reach. It took several tries and a bit of force to get the old part to release from the cabinet.

In stalling the new part was easer that the instructions explaned. There was no need to split the original plug. I unplugged the old switch, plugged in the new and snapped it into place. 30 seconds after I started the reinstall it was in the cabinet and working

Dryer would shut off mid way through cycle and give an E1 error code
After turning off the power to the dryer I removed two screws to the bottom front panel and droped it out of the way. I remved three screws hloding the lint screen in place just for better axcess to the element. I then removed the two wires attached to the element and then the two screws holding the element in place. I put everything back together in reverse. I also took the time to clean any dust and lint out.
