  If the trouble with your Mitsubishi Electric Air Conditioner is not reoccurring and is logged, it could be due to temporary defects like protection device activation in the refrigerant circuit (including the compressor), loose wiring, or noise. Re-examine the symptoms and inspect the installation environment, refrigerant level, weather conditions when the issue occurred, and wiring connections. Also, after servicing, remember to reset the check code logs and restart the unit.
