  If your Mitsubishi Electric Air Conditioner displays 'PLEASE WAIT ? check code', it could be due to the connector for the outdoor unit’s protection device not being properly connected. Ensure this connector is securely connected. Alternatively, it may be caused by reverse or open phase wiring for the outdoor unit’s power terminal block. In this case, you should check and rectify the phase wiring.
