Thermostat, Internal-Bias

Product Description

Thermostat, Internal-Bias Specifications

  • The internal-bias thermistor prevents the dryer from overheating by monitoring and controlling the temperature of the inside of the dryer drum. A thermistor is a resistance thermometer. The thermistor resistance decreases as the dryer temperature increases. Once the resistance is at the maximum, the control panel will shut off the heat. Once the temperature decreases and the resistance increases, that will allow the control panel to turn on the heat to begin another heat cycle, keeping the temperature inside the dryer relatively constant for effective drying.

What does this part do:

The internal-bias thermistor allows the dryer to heat while preventing it from overheating by monitoring and controlling the temperature of the inside of the dryer drum. A thermistor is a resistance thermometer. The thermistor resistance decreases as the dryer temperature increases. Once the resistance is at the dryer maximum, the control panel will shut off the heat. Once the temperature decreases and the resistance increases, the control panel will turn on the heat to begin another heat cycle, keeping the temperature inside the dryer relatively constant for effective drying.

Why does this part break:

Thermistors are prone to wear and malfunction with normal dryer use, over time.

What happens when this part breaks:

If your thermistor is defective, drying time could be prolonged or you could get a fault code. You could also notice your dryer overheating. Although it is a common mistake, a defective thermistor is not responsible for a dryer not heating.

Attaches to:

It is located on the blower housing, next to the thermal fuse.

Replace part if:

You can test the outlet thermistor on a multimeter, it should read 10Kohms (10,000 ohms) of resistance at room temperature. It can tolerate 10% fluctuation. If your reading indicates the part is defective, it will need to be replaced.

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.
