Refrigerator Defrost Thermostat

Frigidaire offers a range of products, including those under the Frigidaire and Electrolux brands. They also manufacture items for Sears-Kenmore. This defrost thermostat is an original equipment manufacturer (OEM) replacement part designed for Frigidaire refrigerators and freezers. Its primary function is to prevent the defrost heater from overheating, thereby protecting the evaporator.

To troubleshoot, use a multi-meter to check the thermostat. It should show closed continuity when the freezer temperature is around 15 degrees Fahrenheit. If it shows open continuity, replacement is necessary.

Common issues this part addresses include:
- Freezer not defrosting
- Refrigerator being too warm
- Freezer section being too warm
