Possible Causes
Open door frame heater element, Loose heater wiring, Faulty main control board heater control
How to Fix / Troubleshooting
Safety first: Unplug the freezer. Door frame heaters can be embedded and not directly visible.
Steps:
- Inspect the door frame and gasket area for excessive condensation or frost.
- Access the wiring harness for the door frame heater (often routed through the cabinet near the hinge area).
- Check connectors for looseness or corrosion; reseat as needed.
- Test the heater circuit for continuity with a multimeter; an open circuit indicates a failed heater.
- If the heater is open, the door frame heater assembly or door harness must be replaced (this may require door replacement on some Ocean models).
- If the heater is good but not powered, the main control board may be defective.
