How to Fix / Troubleshooting
Safety first: Unplug the refrigerator. Wipe up water to prevent slips.
Steps to check:
- Clear defrost drain: Access the freezer evaporator area and flush the drain hole with warm water until it flows freely to the pan.
- Inspect drain pan: From the rear bottom, check the drain pan for cracks or misalignment. Replace if damaged.
- Check door gaskets: Inspect gaskets for gaps or tears that allow warm air in, causing excess frost and water. Replace damaged gaskets.
