Possible Causes
Refrigerant leak or low charge, Failed compressor, Condenser coil extremely dirty, Door or bin not sealing properly
How to Fix / Troubleshooting
Safety first: Unplug the unit before cleaning or inspecting mechanical components.
- Check door/bin seal: Inspect the bin door gasket for tears or gaps. Ensure the door closes fully and latches properly.
- Clean condenser: Remove the service panel and clean the condenser coil with a brush and vacuum to improve heat rejection.
- Verify fan operation: Confirm both condenser and evaporator fans run when the compressor is on.
- Monitor temperature: After cleaning, restore power and allow several hours of operation. If H1 returns and the unit does not cool, a sealed system issue (refrigerant leak or compressor failure) is likely.
- Call a technician: Sealed system repairs require EPA-certified service and specialized tools.
