The Defrost Thermostat is an OEM part for Whirlpool refrigerators. This thermostat monitors the temperature of the evaporator coil and activates the defrost heater to melt any frost that has accumulated. This process ensures efficient cooling and prevents ice build-up in the freezer.
You should replace the defrost thermostat if it becomes faulty or damaged. Causes of a bad defrost thermostat can include regular wear and tear, electrical issues, or exposure to extreme temperatures that can lead to malfunctioning.
Symptoms of a bad defrost thermostat include:
- Frost build-up in the freezer
- The refrigerator running constantly or not cooling properly
- Water leaks inside the refrigerator
- The defrost heater not activating
This OEM part is also compatible with Maytag, KitchenAid, Jenn-Air, Amana, Magic Chef, Admiral, Norge, Roper, and Kenmore models.
