Why does my Gree GMV emit an odor?
If your Gree Air Conditioner emits an odor, it's possible that the unit is blowing out room odors that it has absorbed. Unfortunately, the provided manual extract does not offer a solution.
What happens when there is a mode conflict in Gree Air Conditioner?
When the indoor operating mode conflicts with that of the outdoor unit, the indoor fault indicator will flash and a conflict will be shown on the wired controller after 5 minutes. The indoor unit stops running, and the system changes the outdoor operating mode to match the indoor unit. After this adjustment, the unit should return to normal operation. Note that COOL mode does not conflict with DRY mode, and FAN mode does not conflict with any mode.
Why doesn't the indoor fan start during heating in my Gree Air Conditioner?
The indoor unit (IDU) fan may not start immediately during heating. This is because the fan is designed to wait until the heat exchange becomes hot to prevent delivering cool air. Also, during defrosting, the IDU fan may stop because the system switches to cooling mode to prevent delivering cool air. The fan will resume operating after defrosting. In both cases, allow the system time to complete its process.
