Possible Causes

Clogged defrost drain hole, Frozen drain tube, Misaligned drain pan above compressor, Excessive door openings causing condensation

How to Fix / Troubleshooting

Unplug the cooler before working inside.

  • Locate the drain: Inside the cabinet, at the bottom of the evaporator area, there is usually a small drain hole.
  • Clear blockage: Use a soft pipe cleaner or plastic probe to gently clear debris from the drain hole. Do not use sharp metal objects.
  • Flush with warm water: Use a turkey baster or syringe to flush warm (not boiling) water through the drain to melt any ice and push debris into the rear drain pan.
  • Check rear drain pan: At the back, ensure the drain tube empties into the pan above the compressor and that the pan is properly seated.
  • Reduce humidity load: Avoid leaving the door open for long periods and ensure the gasket seals well to minimize condensation.

Persistent leaks after clearing the drain may indicate a cracked drain tube or liner, which should be inspected by a technician.
