  If your Gree Air Conditioner stops after running for a bit, first check for any obstacles blocking the condenser and remove them. Next, examine the control loop for any abnormalities. Also, if you're using cooling operation, ensure the outdoor temperature isn't above 48°C.

  If your Gree Air Conditioner isn't heating well, begin by cleaning or replacing the air filter. Ensure all doors and windows are firmly closed and increase the set room temperature. Inspect for refrigerant leakage and verify that the outdoor ambient temperature is not lower than -5°C. Also, examine the control loop for any issues.
