CRITICAL SAFETY WARNING: Unplug refrigerator before servicing. Defrost heaters are high voltage (120V).

  1. Unplug refrigerator and move it away from the wall.
  2. Remove freezer shelves, baskets, and back panel to access the evaporator coils.
  3. Locate the defrost heater at the base or wrapped around the evaporator.
  4. Disconnect wiring harness from heater terminals (note locations or take a photo).
  5. Remove mounting screws or clips securing heater to evaporator.
  6. Carefully remove old heater (avoid damaging coils or insulation).
  7. Position new heater in the same orientation and secure with mounting hardware.
  8. Reconnect wiring harness to correct terminals.
  9. Reinstall evaporator cover, shelves, and baskets.
  10. Plug in refrigerator and monitor operation—allow 24 hours for normal cooling and defrost cycles.

Safety Notes: If heater fails repeatedly, check defrost thermostat and control board for faults. Clean any ice buildup before reassembly.

  1. Test old heater for continuity (expect 20–80Ω); infinite = open circuit.
  2. Replace defrost thermostat with heater if it’s clipped to the same location.
  3. Inspect wiring for heat damage or corrosion—repair as needed.
  4. If ice returns quickly after replacement, check defrost timer or control board.
  5. Clean evaporator drain to prevent water pooling after defrost.
  6. Use only OEM heaters—aftermarket may not match wattage or fit.
  7. Document installation for warranty and service records.
  8. If evaporator cover is hard to reinstall, don’t force—check for ice or misaligned wiring.
  9. Allow 24 hours for refrigerator to stabilize after repair.
  10. If freezer temperature rises after install, verify heater operation with amp clamp or cycle test.
  11. Monitor for leaks—ensure drain pan is clear and in place.
