The internal-bias thermistor (Thermistor, Dryer Thermister, Dryer Thermistor) prevents the dryer from overheating by monitoring and controlling the temperature of the inside of the dryer drum. It is located on the blower housing, next to the thermal fuse. If your thermistor is defective, drying time could be prolonged or you could get a fault code. You could also notice your dryer overheating. 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. This model is white plastic. It is sold individually.

Customer Repair Stories
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.

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.
