Description
Product Description
Ensure your refrigerator’s defrost cycle functions properly with the genuine OEM GE WR51X10029 Defrost Heater Assembly. This part is built to GE’s original specification and is designed to replace malfunctioning or failed defrost heater assemblies that allow ice and frost to build up on the evaporator coil, compromising cooling performance. geapplianceparts.com
Because defrost systems differ by model, refrigerant type, liner style and year, please check with your maintenance technician prior to ordering to confirm compatibility with your appliance model and full component configuration.
Replacing the heater assembly can restore efficient cooling, reduce compressor run-time, eliminate frost accumulation and extend appliance life.
Features & Benefits
-
OEM quality fit — Genuine GE part ensures correct specifications and fit for models listing WR51X10029. geappliances.com+1

-
Reduces service visits & failures — Installing the correct heater assembly means fewer trips, less downtime, better performance.
-
Cost-effective repair — Rather than replacing the entire refrigeration system, a new heater assembly corrects a common failure point.
-
One-year limited warranty — The OEM listing from GE includes warranty protection. geapplianceparts.com
Common Symptoms That Indicate Replacement Is Needed
-
Ice or frost build-up visible on the evaporator coil behind the freezer wall. geapplianceparts.com
-
Refrigerator or freezer runs continuously or longer than normal and fails to maintain proper cold temperatures.
-
Freezer feels cold but fresh-food compartment is warm (often a defrost cycle failure symptom).
-
Water pooling in the freezer or refrigerator because the defrost melt water is not draining.
-
You hear the defrost heater being powered (click or relay) but no heat generates — often the assembly has failed.
Compatible Models (Partial List)
This heater assembly fits many GE, Hotpoint, Kenmore and affiliated refrigerators that list WR51X10029 in their parts breakdown. Example model families:

Compatibility Notes
-
Confirm that your model uses a defrost heater harness/assembly of the same shape/length and connection style as WR51X10029.
-
The defrost system includes heater, thermostat, drain, timer or control board—replacing the heater alone may not resolve issues if other components are faulty.
-
Always disconnect power before servicing defrost components to avoid electrical hazard.
-
Some newer models use different refrigerants (R600a, etc) or different heater designs—ensure your technician verifies fit.
-
While this part addresses defrost heater failures, it will not correct cooling problems caused by compressor failure, refrigerant leak or airflow restriction.
