Jenn-Air Defrost Thermostat

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.

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 !
