How to Fix / Troubleshooting
Safety: Unplug the cooler before defrosting or removing panels. Do not use sharp tools to chip ice.
Steps:
- Manual defrost: Turn off and unplug the unit. Open the door and place towels to catch water. Allow all ice to melt completely (may take several hours).
- Check door gasket: Inspect the door gasket for cracks or gaps. Replace if damaged. Ensure the door closes squarely.
- Inspect defrost components (if equipped): Access the evaporator and test the defrost heater and defrost sensor for continuity. Replace failed parts.
- Clear drain: If there is a drain hole under the evaporator, clear it with warm water and a small brush to prevent refreezing.
