What causes AC voltage to be abnormal in my Hisense AUC-36UR4SAEA1 Air Conditioner?

Abnormal AC voltage in your Hisense Air Conditioner can be due to: * AC voltage outside the range of 160V to 275V: This is a normal protection response; check the power supply. * Abnormal AC voltage in the sampling circuit on the drive board: Replace the drive board.
