Description
Product Description
Ensure reliable defrost operation in your refrigerator with the GE WR50X122 Defrost Thermostat. This bi-metal thermostat is designed to monitor the evaporator’s temperature during a defrost cycle—cutting power when the coil reaches about 60°F to prevent overheating, and re-allowing operation once the coil has cooled.

Because defrost system components vary by model, liner type, refrigerant and age, please check with your maintenance technician prior to ordering to confirm compatibility with your specific appliance model and assembly.
Features & Benefits
-
OEM-manufactured spec: Genuine GE part ensures correct fit and spec compliance. PartSelect
-
Critical defrost safety: Helps ensure the defrost heater shuts off at the correct temperature, preventing coil over-heating or incomplete defrost. geapplianceparts.com+1
-
Simple two-wire installation: Streamlined replacement compared to full assemblies—ideal when the thermostat is the failing component in the defrost system. mccombssupply.com
-
Repair cost-effective: Replacing a malfunctioning thermostat is often far less expensive than full board/evaporator replacements when defrost failure is the root cause.
Common Symptoms That Indicate Replacement Is Needed
-
Freezer shows heavy frost/ice accumulation on the evaporator coil behind the liner, despite compressor & fan working. PartSelect+1
-
Fresh-food compartment running warm, freezer struggling to reach temperature, or fridge runs continuously without cooling effectively. PartSelect
-
Defrost heater runs continuously because thermostat does not open; or heater never comes on because thermostat fails to close.
-
You’ve replaced the heater and timer but still have frost build-up—thermostat may still be the culprit.
-
Freezer section too cold while fridge section is warm (imbalance indicating defrost system not cycling). PartSelect

Compatibility Notes
-
Confirm the thermostat’s clip size (typically for 5/16″ tubing) and mounting location match your appliance. mccombssupply.com
-
Even if the thermostat is replaced, if your defrost system has other faults (heater, timer, board, evaporator fan), the issue may persist—have a technician check the full system.
-
Disconnect power before working on defrost components to avoid electrical or refrigerant hazards.
-
While relatively simple to install, improper placement (wrong mounting, loose connection) may cause premature failure or improper defrosting.
