Why does my Midea MSG-18HR Air Conditioner keep resetting?
The resetting phenomenon often occurs during operation because the instantaneous voltage of the main chip is less than 4.5V. To resolve this, check the indoor PCB and fan motor.
What to do if my Midea MSG-18HR shows an EEROM error and the indoor PCB is defective?
If your Midea Air Conditioner displays an EEROM error and the indoor PCB is defective, replace the indoor PCB.
