Possible Causes
How to Fix / Troubleshooting
Safety: Unplug the refrigerator before accessing the freezer evaporator and electrical components.
- Inspect evaporator: Remove the freezer rear panel and check for heavy frost buildup.
- Visual check of heater: The defrost heater is typically a glass or metal tube at the bottom of the evaporator. Look for burn marks or breaks.
- Check wiring: Inspect the heater wiring and connectors for signs of overheating or disconnection.
Testing the heater and defrost circuit requires a multimeter. If the heater is open (no continuity), replace it. If the heater tests good, the main control board may not be energizing the heater and may need replacement.
