How to Fix / Troubleshooting
Safety: Unplug the unit before defrosting or accessing the evaporator. Do not use sharp tools to remove ice.
Steps to address frost:
- Manual defrost: Remove all bottles, unplug the cooler, and leave the door open until all ice has melted. Use towels to catch water.
- Inspect gasket: Check the door seal for gaps or damage that could allow moist air in. Replace if necessary.
- Check defrost components: After defrosting, access the evaporator and test the defrost heater and sensor for continuity and correct resistance. Replace faulty parts.
- Monitor operation: Reassemble, restore power, and monitor for recurring frost. Persistent issues may indicate a control board problem.
