Customer Questions and Answers for Defrost Thermostat by Frigidaire

The Defrost Thermostat is an OEM part for Frigidaire refrigerators and freezers. This part senses the temperature of the evaporator coil and triggers the defrost heater to melt away any accumulated frost. This process ensures that air can flow freely over the coils, keeping the refrigerator or freezer at the correct temperature and preventing overcooling or temperature fluctuations that can spoil food.

Causes of a bad defrost thermostat can include a failure to open or close properly, leading to an overaccumulation of frost on the evaporator coils, or physical damage that prevents it from sensing the correct temperature. 

Symptoms of a bad Defrost Thermostat include:

• Frost build-up in the freezer compartment
• The refrigerator or freezer is too warm
• The compressor running longer than usual
• Fresh food compartment becoming too warm

This OEM Frigidaire part is also compatible with Electrolux, Gibson, Kelvinator and some Kenmore models.
