Possible reasons for the non-rotation of the exhaust fan of Gree air conditioner: 1, poor contact of the main control switch. 2. The fan motor of outdoor air conditioner is damaged. 3. The capacitor of the starting fan is damaged. 4. The fan motor coil is damaged. 5. The fixing screw between the fan motor and the blade is loose. 6. Because the power supply voltage is low, the compressor can't work normally, so a voltage regulator is needed. 7. The compressor is damaged.

Excluding the above situation, it may also be because the outdoor unit of air conditioner will adsorb a lot of dust and garbage on the radiator after long-term use, resulting in poor heat dissipation or poor ventilation. It is recommended to maintain and clean the air conditioner regularly.

The answer is applicable to Gree GMV-H 160WL/A air conditioner.
