WR50X55 - GE Refrigerator Defrost Thermostat

The Defrost Thermostat (WR50X55) is a genuine part designed by GE specifically for their refrigerators. This part, sometimes referred to as a defrost bi-metal thermostat, is a critical component in the defrost system of your refrigerator. It operates by sensing the temperature of the evaporator coils, and when the temperature drops to a certain point, it triggers the defrost heater to melt any frost that has accumulated on the coils.

The location and function of this part may vary slightly based on your refrigerator's model. It's important to note that if this part is not functioning correctly, it can lead to several symptoms. These may include the refrigerator not cooling properly, frost build-up in the freezer, or the freezer section becoming too warm.

If your refrigerator exhibits any of these symptoms, replacing the defrost thermostat (WR50X55) may be necessary to resolve these issues. As always, it's recommended to check the model number of your appliance to ensure compatibility with this part before purchasing.
