In brief
Fault code H6 on Gree Wall-mounted / Console means: Fault code H6 indicates that the electronic control board does not detect rotation of the indoor fan (no Hall sensor feedback). Most common cause: Fan wheel mechanically blocked (object, dust), faulty fan motor, or defective Hall effect sensor in the motor. First action: Push the fan wheel with a tool (power off): it should rotate freely.. Call a registered engineer if the fault returns after basic checks or involves refrigerant work (F-Gas registered engineer required).
According to the Gree Indoor Unit Service Manual, the H6 fault code is triggered when the PCB does not receive a speed feedback signal from the indoor fan motor.

What does fault code H6 on Gree mean?
Fault code H6 indicates that the electronic control board does not detect rotation of the indoor fan (no Hall sensor feedback).
Fan wheel mechanically blocked (object, dust), faulty fan motor, or defective Hall effect sensor in the motor.
Symptômes
- No airflow
- The louvre opens but nothing happens
- Motor growling noise
Diagnostic
1. Manual rotation check
- Push the fan wheel with a tool (power off): it should rotate freely.
2. Connector check
- Check that the motor connector is securely clipped onto the PCB (it can become loose due to vibration).
How to reset fault code H6 on Gree?
Replace the fan motor.
When should you call an F-Gas engineer?
After cleaning filters with the fan wheel blocked by a mis-fitted filter, or a seized fan motor.
Affected models
- Split Gree
- Ducted
Field context
After cleaning filters with the fan wheel blocked by a mis-fitted filter, or a seized fan motor.
Technical source data
The H6 Gree fault concerns a defective indoor fan motor: no speed feedback signal to the PCB. Check fan wheel, motor and wiring before replacing the PCB.
Questions fréquentes
H6 Gree: motor or PCB first?
First check that the fan wheel rotates freely and that the motor is receiving power — H6 is a fan speed feedback fault.
