Why is my Gree Air Conditioner not cooling properly?
- S
  Sarah CochranAug 9, 2025
  Several factors can cause a Gree Air Conditioner to have a poor cooling effect. The air filter might be dirty or blocked, so cleaning or replacing it is recommended. There might be too many people or heat sources in the room; try to reduce these. Ensure all doors and windows are closed. Obstacles at the air intake or outlet should be removed. The set temperature might be too high, so lower it. A refrigerant leakage could also be the cause, requiring a check and refill. Lastly, the room temperature sensor might be faulty, and testing or replacing it may be necessary.

  If your Gree Air Conditioner operates for a while and then stops, check for any obstacles in front of the condenser and remove them. The control loop might be abnormal, requiring a check and repair. Also, if you're using cooling operation when the outdoor temperature is above 48°C, change the operation mode.

  To improve the heating effect of your Gree Air Conditioner, start by cleaning or replacing the air filter if it's dirty or blocked. Ensure that all doors and windows are firmly closed. If the set room temperature is too low, raise it. Check for refrigerant leakage and refill if necessary. If the outdoor temperature is below -5°C, consider supplemental heating or check if the operation is appropriate. Finally, check and repair the control loop if it is abnormal.

  If your Gree Air Conditioner won't start, first check the power supply connection. If the leakage switch is tripping, inspect for electrical leakage and correct it. Also, make sure the operating keys are not locked and unlock them if they are. If none of these resolve the issue, test and repair the control loop.
