How to Fix / Troubleshooting
Safety First: Unplug the unit before defrosting. Do not use sharp tools to remove ice.
- Step 1 – Inspect and replace gasket: Look for gaps or tears in the door gasket. Replace if damaged.
- Step 2 – Defrost interior: Turn off the unit, open the door, and allow frost to melt. Use towels to catch water.
- Step 3 – Check door alignment and hinges: Adjust so the door closes squarely and seals all around.
Reducing door openings and humidity in the room will also help prevent frost buildup.
