Product Description
Restore proper defrost performance and protect your refrigerator from frost buildup with the genuine OEM kit model WR50X50 from GE. This kit includes a defrost thermostat that is rated to trip out at approximately 50 °F and reset when temperature drops to around 30 °F, plus interchangeable brackets and crimp-style connector wires for installation. grainger.com+3PartSelect+3Midwest Appliance Parts Co, Inc.+3
Because defrost systems vary with liner style, refrigerant type and model year, please check with your maintenance technician prior to ordering to verify compatibility and correct part for your specific appliance.
Features & Benefits
-
OEM quality fit: Genuine GE replacement ensures the thermostat meets original specifications for reliability and fit. GE Appliance Parts+1
-
Critical defrost control: Helps the refrigerator’s defrost cycle function correctly—when the thermostat fails, frost can accumulate on the evaporator coil, reducing cooling efficiency. PartSelect
-
Includes installation hardware: Brackets and connectors included simplify installation and reduce need to source additional parts. PartSelect
-
Cost-effective maintenance solution: Replacing a failing defrost thermostat is much more economical than replacing large components or dealing with long-term performance degradation.
Common Symptoms That Indicate Replacement Is Needed
-
Frost or ice buildup visible on or around the evaporator coil (behind the freezer wall panel)
-
Freezer runs colder than normal while fresh-food side runs warm, or significant temperature imbalance
-
Refrigerator/freezer runs continuously (compressor stays on long) with increased power draw
-
Ice forming in the freezer drain pan or water not draining properly (frost blocking drain)
-
Items in the freezer feel frosty or freezer compartment seems colder than before but doesn’t hold properly
-
Thermostat test (by technician) shows that the defrost thermostat does not open at ~50 °F or fails to close when the coil is warm
If you’re seeing one or more of these signs, a kit such as WR50X50 may restore correct defrost function—however, installation should follow technician verification of fit and system health.

Compatibility Notes
-
Verify that your refrigerator’s defrost thermostat is located at the correct position (usually clipped to the evaporator coil or nearby) and that its specifications (trip temperature, mounting bracket style) align with WR50X50. PartSelect+1
-
Because the defrost cycle depends on other components (heater, timer/control board, drain system), replacing this thermostat alone may not fix symptoms if the root cause is elsewhere—have your technician check the full defrost system.
-
Ensure that any wiring harnesses, mounting brackets, or clip connections from the original are compatible with the new kit; while hardware is included, some models may require adaptation.
-
Since this part is quite low cost, but the wrong fit will result in repeat service, technician verification prior to ordering is strongly recommended.
