How to Fix / Troubleshooting
Safety first: Unplug the unit before defrosting. Do not use sharp tools to remove ice.
Steps to address frost buildup:
- 1. Manual defrost: Turn off and unplug the cooler. Open the door and allow all ice to melt. Use towels to absorb water.
- 2. Check door gasket: Inspect for gaps or tears. Close the door on a sheet of paper; if it pulls out easily, the gasket may need adjustment or replacement.
- 3. Inspect defrost components (if auto-defrost): Remove the interior rear panel and check the defrost heater and sensor. Test for continuity and replace any failed parts.
- 4. Verify sensor placement: Ensure the defrost thermistor is properly clipped to the evaporator coil where designed.
- 5. Reassemble and monitor: After repairs, reassemble and monitor for several days. Frost should form lightly and melt during defrost cycles, not accumulate heavily.
