Refrigerator Defrost Heaters

Keep your refrigerator and freezer operating efficiently by replacing a faulty defrost heating element. During the automatic defrost cycle, the defrost heater melts frost and ice accumulation off the evaporator coils, preventing airflow blockages, excessive warm temperatures, and frost buildup inside the cabinet. Whether your unit utilizes a traditional Calrod heater, a glass radiant heating element, or a complete defrost heater kit, selecting a model-compatible replacement restores proper cooling performance.

We supply exact fit and high-quality replacement defrost heaters for leading major appliance brands, including Whirlpool, GE, Frigidaire, Electrolux, Samsung, Kenmore, Maytag, KitchenAid, Amana, and Bosch.

Signs Your Refrigerator Defrost Heater Needs Replacement

  • Excess Frost on Freezer Back Wall: Heavy frost or solid ice buildup behind the rear freezer panel blocks cold airflow to the fresh food section.

  • Fresh Food Compartment Is Too Warm: Evaporator coils choked with frost restrict air circulation, causing temperatures to rise in the refrigerator section while the freezer remains cold.

  • Long Compressor Run Times: The unit runs continuously trying to reach set temperatures due to restricted airflow.

  • No Heat During Manual Defrost Test: Testing continuity with a multimeter shows an open circuit (no continuity) across the heater terminals.


How to Select the Right Defrost Heater

  1. Locate Your Appliance Model Number: Refrigerator defrost heaters vary in shape, length, wattage, terminal design, and voltage (120V vs 220V). Always check the model sticker inside your refrigerator frame to ensure exact fitment.

  2. Match OEM Part Numbers: Cross-reference your original manufacturer part number (e.g., WR51X10055, 242044008, W10495967, DA47-00244U, WP67002135) with our product catalog.

  3. Verify Dimensions & Terminal Connections: Compare overall heater length, tube diameter, glass sheath type, and wire terminal harness connection before ordering.
