GE Refrigerator Defrost Heater Parts — Models & Compatibility

If your GE side-by-side is building up frost in the freezer section or you're seeing ice forming on the back wall, there's a good chance the defrost heater assembly has failed. This hub covers the WR51X10055 defrost heater and bracket assembly — the most common replacement for GE, Hotpoint, and Kenmore models in the GSS25, GSH25, and GSL25 series. This part replaces several older versions including WR51X10030 and AP3183311.

Is This the Right Part for Your Model?

Check your refrigerator's model number against the compatibility list below. You'll find the model tag inside the fresh food section, usually on the left or right wall near the top. GE side-by-side models from the mid-2000s through early 2010s commonly use this defrost heater assembly. The WR51X10055 includes both the heating element and mounting bracket, so you're getting everything needed for a complete repair.

About This Replacement Part

The defrost heater assembly sits beneath the evaporator coils in your freezer. During each defrost cycle (typically every 8-10 hours), this heater turns on for about 20 minutes to melt any frost buildup on the coils. When it fails, frost accumulates and blocks airflow — your freezer gets too cold while the fresh food section doesn't get cold enough. The WR51X10055 is a direct OEM-equivalent replacement that includes the aluminum mounting bracket pre-attached to the heater element. This assembly is designed for GE side-by-side models with bottom-mounted evaporators, particularly the 25 cubic foot capacity units. Installation requires removing the freezer's back panel to access the evaporator compartment.

What You Need to Know Before Ordering

This assembly comes as one complete unit with the bracket already attached — you don't need to transfer your old bracket. The heater element is the glass-tube type with wire terminals at each end. Make sure you're seeing actual frost buildup in the freezer before replacing this part. If your refrigerator isn't cooling at all, the problem might be the defrost timer, defrost thermostat, or even the compressor instead. The defrost heater specifically addresses frost accumulation issues.
