Thermador Defrost Thermostat
Genuine Whirlpool part
By: Whirlpool
Part Number: WPW10225581

The Defrost Thermostat is an OEM part for Whirlpool refrigerators. It is responsible for monitoring the temperature of the evaporator coils. When the coils reach a certain temperature, the thermostat signals the defrost heater to turn on and melt any ice or frost buildup. This ensures proper airflow and prevents excessive ice formation.

Causes of a bad defrost thermostat can be attributed to normal wear and tear over time or electrical malfunctions.  

Symptoms of a bad defrost thermostat include:

  • Excessive ice buildup in the freezer section.
  • Inadequate cooling in the refrigerator compartment.
  • Frost or ice accumulating on the evaporator coils.

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

This part fixes the following symptoms
  • Frost buildup
  • Freezer not defrosting
  • Freezer section too warm
  • Fridge too warm

Do-It-Yourself Stories from Customers like You Fridge side wasn't staying cold massive ice build up in freezer ice blockage in fan duct   Christopher M. • Yorba Linda , CA • December 15, 2014

Condenser was encased in solid block of ice due to automatic defrost not working. Replaced thermostat and ADC control board. Working fine now. Most tedious part was using a heat gun to melt all the ice off the condenser coils. You will need a couple small wire nuts to splice the new thermostat into the existing harness (they are not included). Service tech wanted over $400 to repair, fixed it myself for half that. Thanks !
