Possible Causes

Door gasket leaking warm moist air, Door frequently opened, Defective defrost sensor or heater (if equipped), Thermostat set too low

How to Fix / Troubleshooting

Always unplug the cooler before defrosting or inspecting components.

Steps:

  • Manual defrost: Remove all bottles, unplug the unit, and allow the ice to melt. Place towels to catch water. Do not use sharp tools to chip ice.
  • Inspect door gasket: Check for gaps, tears, or hardened sections. Close the door on a sheet of paper; if it pulls out easily, the gasket may not be sealing. Replace the door gasket if needed.
  • Check temperature setting: Raise the set temperature slightly to reduce frost formation.
  • Defrost components (if present): On compressor models with automatic defrost, inspect the defrost sensor and defrost heater for continuity. Replace any open components.
