Customer Questions and Answers for Thermistor by Whirlpool

4.89 (64)
By: Whirlpool
Part Number: OEM18040551
Manufacturer Part Number: WP8577274

The Thermistor is an OEM part for Whirlpool brand dryers. It is a temperature-sensing resistor that monitors air temperature changes during the drying cycle. The thermistor provides feedback to the control board on heating element performance and internal air condition. 

Symptoms of a failed thermistor include:

  • Inaccurate temperature readings and selections  
  • Improper or incomplete drying
  • Safety issues from overheating due to lack of feedback
  • Error codes displayed on the control panel

Causes can be related to normal wear and environmental exposure over time. Failure prevents the dryer from achieving optimal drying conditions.

This OEM Whirlpool part can also be used on Maytag, KitchenAid, Jenn-Air, Amana, Magic Chef, Admiral, Norge, Roper, and Kenmore/Sears brand appliances.

For Whirlpool Thermistor (Part Number: OEM18040551)

Joy for Model Number gew9200lw0 (Whirlpool Duet Dryer)

I replaced the heating element after testing. Dryer is heating but turns off/ends cycle resulting in wet clothing. Later on the dryer was stuck on sensing and wasn't working and I found out the thermal fuse blew so I replaced that. I cleaned out the lint screen, venting hose, inside the dryer as best I could. Now, I'm wondering if I should test/replace the Thermistor or the High Limit thermostat? I'm nervous that the motor is dying. I don't want to use several cycles to dry with few articles of clothing and make matters worse.

Answer

HI Joy. Thank you for all the information. The blower housing has a thermistor that senses the temperature to the control board. This is the part #WP8577274. Double check the outside vent cap/ hood assembly while you are at it to make sure the vent cap operates normally. Turn off the breaker,unplug the unit. make sure your dryer cord screws are tight on the terminal block. Thank you.
