  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.

  The Mitsubishi Electric Air Conditioner trouble might not be reoccurring but is logged due to temporary defects, such as the activation of protection devices in the refrigerant circuit including the compressor, poor wiring connections, or noise. Consider these temporary defects by re-checking the symptom and inspecting the installation environment, refrigerant amount, weather conditions when the trouble occurred, and wiring. After finishing the service, reset the check code logs and restart the unit. Also, it is possible that there is no abnormality in the electrical component, controller board, remote controller, etc.
