  Several factors can cause a Gree Air Conditioner to have a poor cooling effect. The filter might be dirty and needs cleaning or replacement. The room may have too heavy a heat load, like too many people. Doors or windows may be open, letting warm air in. The indoor unit's inlet and outlet could be blocked. The temperature setting might be too high, so lower it. Finally, there might not be enough refrigerant due to a leak. Check refrigerant levels and fix any leaks.

  A Gree Air Conditioner might have a poor heating effect due to several reasons. The filter could be dirty, so clean or replace it. An open door or window could be letting cold air in, so close them. The set temperature might be too low, so increase it. Also, insufficient refrigerant, possibly from a leak, could be the cause. Check refrigerant levels and fix any leaks.

  If your Gree Air Conditioner stops after running for a while, it might be because the inlet or outlet of the outdoor (ODU) or indoor unit (IDU) are blocked. Remove any obstacles that are blocking the inlet or outlet.

  If your Gree Air Conditioner won’t start, there are several things to check: * Make sure the power supply is properly connected. * Check if the circuit breaker has tripped due to an electrical leakage. * Verify that the input voltage is within the acceptable range. If these steps don't resolve the issue, the main PC-board may be defective, and you should contact an authorized service center.

Why doesn't the indoor fan start during heating in my Gree GMV-ND28ZA/A-T?

  The indoor fan of your Gree Air Conditioner might not start immediately during heating for two reasons. First, the fan may not operate until the heat exchange becomes hot to prevent delivering cool air. In this case, wait for the heat exchange to become hot before the fan operates. Second, during defrosting, the fan might stop because the system switches to cooling mode, also to prevent delivering cool air. Allow the defrosting process to complete before the fan resumes operation.
