This dryer thermistor is a genuine replacement component designed to monitor and regulate internal temperature in Whirlpool dryers. Mounted on the blower housing, it plays a critical role in controlling the heating element by adjusting resistance as temperatures rise, signaling the control board to maintain safe and efficient drying conditions. A malfunctioning thermistor can result in symptoms such as no heat, overheating, premature cycle termination, or failure to start. It may also trigger fault codes like F-22, F-23, E1, or E2. Replacing the thermistor restores proper temperature regulation, protects the appliance from damage, and improves drying performance. Installation should be performed with the dryer unplugged and may require basic tools.

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 ove

rheated. 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!
