GE WR50X10068 Refrigerator Defrost Thermostat Replacement

The GE WR50X10068 is a defrost thermostat designed for use in compatible General Electric refrigerators. This small but critical component sits near the evaporator coils and monitors their temperature. When the coils get cold enough to accumulate frost during normal operation, the thermostat triggers the defrost heater to warm the coils and melt the ice. Once the coils reach a set temperature, it shuts the heater off again. This cycle keeps the evaporator running efficiently and prevents the ice buildup that leads to poor cooling, unusual noises, or water leaks inside the unit.

When a defrost thermostat fails, the symptoms are hard to miss: heavy frost coating the freezer walls, the refrigerator section warming up, or the unit running constantly as it struggles to maintain temperature. Replacing the WR50X10068 is a common DIY repair that typically involves removing the evaporator cover panel inside the freezer, disconnecting the faulty thermostat from its wiring harness, and clipping the new one into place. The entire job usually takes under an hour for someone comfortable working on appliances, and it can save significant money compared to scheduling a technician visit for what amounts to a simple part swap.
