Questions & Answers

For Whirlpool Dryer Thermistor (Part Number: OEM18022842)

Safraz Y for Model Number maytag gas dryer modle #mdg4806aww

My dryer was taking very long to heat up, so i open the unit up and started checking all the fuses and sensors etc. I replace the gas valve coils and it heated up right away. But I got no continunity on the thermistor, so I order a new one part# 31001590. When I got it I check it but got no continunity also on the new one. Do I need to add heat with a blow dryer and then check it for continunity or did I get a new bad thermistor? Is a no or a nc part and what does the part really does? pls help

Safraz, This is a thermistor that you will check resistance on. You should have approximately 10,000 ohms resistance and is used in conjunction with sensor bars.

John If you are getting no continuity through the thermistor this means that it is bad and needs to be replaced.

Hello Froggy, The thermal fuse should always read as a closed circuit. If it is open then it is bad.

Hello Bobby! Check your venting system and make sure it is not clogged. Try doing a load without the vent hooked up and see if the same issue occurs. It could be due to the thermistor or the element, however, before changing any parts we would recommend testing the unit without the vent. Hope this helps.
