WG03F00771 - Genuine OEM GE Refrigerator Defrost Heater Assembly

WG03F00771 – Genuine OEM GE Refrigerator Defrost Heater Assembly

The WG03F00771 Genuine OEM GE Refrigerator Defrost Heater Assembly is an original manufacturer heating component designed for select GE refrigerators and compatible brands. This OEM defrost heater is engineered to melt frost buildup on the evaporator coil during the automatic defrost cycle, ensuring consistent cooling performance and preventing ice blockages. Available from Appliance Kingdom, this part ships across Canada with fast and reliable delivery for homeowners, landlords, and appliance repair technicians.

This component is critical for maintaining proper airflow and temperature stability inside the refrigerator. When frost builds up on the evaporator coils, cooling efficiency drops significantly. Replacing a faulty defrost heater restores proper defrost operation and helps bring the appliance back to normal cooling performance.

Function & Importance of the Defrost Heater Assembly

The defrost heater assembly is responsible for melting accumulated frost and ice from the evaporator coil during scheduled defrost cycles. In GE refrigerators, this process is essential because frost buildup can block airflow between the freezer and refrigerator compartments.

OEM-quality construction matters because the heater must deliver precise heat output without damaging surrounding components or disrupting the refrigerator’s defrost cycle logic. A genuine OEM part ensures correct resistance, safe operation, and long-term reliability under repeated thermal cycling.

When this part fails, frost is no longer removed efficiently, leading to restricted airflow and cooling imbalance throughout the appliance.

Common Symptoms of a Faulty Defrost Heater Assembly

A failing WG03F00771 defrost heater may cause:

• Excessive frost or ice buildup on evaporator coils
• Refrigerator or freezer not cooling properly
• Refrigerator section too warm while freezer may still run
• Airflow blockage inside freezer compartment
• Compressor running longer than usual
• Weak or inconsistent cooling performance
• Ice buildup recurring shortly after manual defrost
• Refrigerator struggling to maintain set temperatures

If these symptoms are present and other defrost components (thermostat, sensors, control board) are functioning correctly, replacing the defrost heater often resolves the issue.
