  If your Gree Air Conditioner isn't working, there are several potential causes. First, check if a fuse is cut off or the circuit breaker tripped; if so, replace the fuse or reset the breaker. Ensure the unit is properly connected to a power supply. Also, a power failure could be the reason; the unit should restart when power is restored. Check the remote controller’s batteries and replace them if needed. Finally, make sure the remote controller is within its operational range (8m).

Why is my Gree GMV-H224WL/A-X heating or cooling abnormally?
- A
  Ashley RobertsAug 9, 2025
  Abnormal cooling or heating in your Gree Air Conditioner can stem from several issues. Start by checking the air inlets and outlets of both indoor and outdoor units for any obstructions and clear them if necessary. Verify that the temperature setting is correct using the remote or wired controller. Also, ensure the fan speed isn't set too low and that the wind direction is properly adjusted via the controllers. Check if any doors or windows are open, and close them. If direct sunshine is affecting the unit, use a curtain or louver. Additionally, too many heat resources in the room can cause this problem, so reduce them where possible. Lastly, a blocked or dirty filter can be the culprit, so clean the filter.
