Frigidaire Defrost Thermostat 5303918202 OEM Part

Frigidaire produces a variety of products, including those under both its own name and the Electrolux brand, and also manufactures for Sears-Kenmore. This defrost thermostat serves as an original equipment manufacturer (OEM) replacement part specifically for Frigidaire refrigerators and freezers. Its main role is to prevent the defrost heater from overheating, which protects the evaporator.

To diagnose potential issues with this part, a multi-meter can be used to test its functionality. The thermostat should display closed continuity when the freezer temperature reaches approximately 15 degrees Fahrenheit. If open continuity is detected, replacing the thermostat is required.

This component commonly resolves problems such as:
- Freezer failing to defrost
- Excessive warmth inside the refrigerator
- Unusually high temperatures in the freezer section
