    Why is my Gree GMV-N140U/A-T Air Conditioner not cooling properly?

      Rebecca CaldwellAug 11, 2025
      Several factors can cause a Gree Air Conditioner to have a poor cooling effect. Check if the air filter is dirty or blocked, and clean or replace it if necessary. Make sure that doors and windows are closed, and remove any obstacles from the air intake and outlet of the unit. Reduce the number of heating sources or people in the room. Also, the setting temperature might be too high, or there could be a refrigerant leak, so adjust the temperature and check for leaks. Finally, the indoor temperature sensor might have poor performance, so consider having it checked.

      A Gree Air Conditioner might not heat well for several reasons: check if the air filter is dirty or blocked and clean or replace it. Ensure that doors and windows are closed. Adjust the temperature setting to a higher level. There might be refrigerant leakage, which requires checking and repair. If the outdoor temperature is lower than -5?, consider alternate heating solutions. Finally, abnormal operation of the control system can cause this, so contact a technician for inspection.

      If your Gree Air Conditioner won't start, begin by checking the power supply. If the circuit breaker has tripped, reset it. Ensure that the circuit voltage is within the acceptable range. Verify that the ON/OFF key is in the start position. If these steps don't resolve the issue, there may be a failure in the control system, and you should consult a technician for repair.

      Your Gree Air Conditioner might stop running after a while due to several reasons. There might be an obstacle in front of the condenser, so remove any obstructions. There could be an abnormal operation of the control system, in which case you should contact a technician for inspection. Also, if you are using cooling mode and the outdoor temperature is higher than 43?, wait for the temperature to drop or switch to a different mode.

      If the indoor fan of your Gree Air Conditioner doesn’t start during heating, it could be due to several reasons: the tube sensor might be improperly located, so reposition it correctly. Ensure the tube sensor is properly inserted. The wiring of the tube sensor could be broken, so repair or replace it. Finally, there could be electricity leakage of the capacitor, in which case you should replace the capacitor.
