GE WR50X55 Refrigerator Defrost Thermostat (55°F)

Restore reliable cooling performance and prevent destructive ice buildup with precise defrost cycle temperature control.

The defrost thermostat is a key safety and regulation component that ensures your refrigerator’s evaporator coils do not overheat during the defrost cycle while also preventing excessive frost buildup. When this part fails, ice can accumulate into solid blocks that restrict airflow, causing the fresh food section to warm while the freezer struggles to maintain proper temperature. Replacing it restores proper cycling between cooling and defrost modes, helping your appliance run efficiently again. Installation is typically straightforward—simply clip the thermostat onto the evaporator coil tubing and reconnect the two wire leads exactly as the original part was installed.
