How to Fix / Troubleshooting
Safety: Unplug the unit and protect the floor from water.
- Manual defrost: Open the door and allow all ice to melt completely. Do not use sharp tools to chip ice.
- Inspect gasket: Check the door gasket for tears or gaps. Replace if it does not seal tightly.
- Check door usage: Reduce frequent or prolonged door openings, which introduce moisture.
- Test defrost sensor: After defrosting, access the evaporator sensor and test its resistance. Replace if out of range.
- Monitor: If frost quickly returns, the control board may not be managing defrost correctly and may need replacement.
