  If your Rinnai Air Conditioner starts and stops frequently, it could be due to several reasons: There might be too much or too little refrigerant in the system, so check for leaks and recharge the system. Air or other foreign material might be in the refrigeration system, requiring evacuation and recharge. A system circuit could be blocked, necessitating identification and replacement of the malfunctioning part. The compressor might be broken and need replacement. Lastly, the voltage could be too high or too low, requiring the installation of a manostat to regulate it.
