Possible Causes
Out-of-range NTC sensor reading, Loose sensor connector, Damaged sensor harness, Faulty sensor input on main PCB
How to Fix / Troubleshooting
Safety: Disconnect power before opening the unit.
Steps:
- Identify sensor: Consult the model label or service manual if available; F1 on many Gree dehumidifiers refers to an indoor coil or ambient sensor fault.
- Inspect sensors: Check both the ambient and coil NTC sensors for secure mounting and intact wiring.
- Measure resistance: Use a multimeter to compare sensor resistance to expected values at room temperature. Replace any sensor that is open, shorted, or far out of spec.
- Reconnect: Reseat connectors on the main PCB and ensure there is no corrosion.
- Board replacement: If sensors test good and F1 persists, replace the main control board.
