How to Fix / Troubleshooting

Safety first: Unplug the refrigerator and mop up any standing water to prevent slips.

Step 1 – Locate the defrost drain:

Inside the freezer, remove the rear panel to access the evaporator.
Find the drain hole at the bottom center of the evaporator tray.

Step 2 – Clear the blockage:

Use warm (not boiling) water in a turkey baster or syringe to flush the drain hole.
Push a flexible plastic tube or pipe cleaner gently down the drain to clear debris.

Step 3 – Check rear drain tube and pan:

At the back of the refrigerator, locate the drain tube exiting into the drain pan.
Ensure the tube is properly seated and not kinked.
Clean the drain pan and confirm it is not cracked.

Step 4 – Reassemble and monitor:

Reinstall the freezer panel and restore power.
Monitor for several days to ensure no further leaks.
