What to do if Gree GMV-450WM/H-X has abnormal cooling or heating?
If your Gree Inverter is showing abnormal cooling or heating, close any open doors or windows and draw any curtains or louvers to block direct sunlight. Reduce the number of heat sources in the room. Also, clean the filter if it is blocked with dirt.
Why is my Gree Inverter cooling or heating abnormally?
If your Gree Inverter is not cooling or heating properly, check that the air intake and outlet of both the indoor and outdoor units are free from obstructions. Also, make sure the temperature setting, fan speed, and wind direction are properly adjusted using the wireless remote controller or wired controller.
How to troubleshoot a Gree GMV-450WM/H-X Inverter that doesn't run?
If your Gree Inverter isn't running, first ensure it's properly connected to a power supply. Then, verify that the voltage is within the specified range. Check the fuse and breaker, replacing the fuse or reconnecting the breaker if necessary. Also, replace the batteries in the remote controller. Finally, make sure you are within the 8m control range of the remote.
What to do if Gree GMV-450WM/H-X Inverter runs but stops immediately?
If your Gree Inverter runs but stops immediately, the air intake or outlet of either the indoor or outdoor unit might be blocked. Remove any obstructions to resolve this issue.
