How to Fix / Troubleshooting
Safety first: Unplug the unit and place towels to catch meltwater before defrosting.

- Step 2 – Clear drain: Flush the drain trough and hose with hot water to remove obstructions.
- Step 3 – Inspect door gasket: Replace any torn or deformed gasket that allows warm air in.
