  If the trouble with your Mitsubishi Electric Heat Pump is not reoccurring but a check code is logged, consider temporary issues like protection device activity in the refrigerant circuit, wiring problems, or electrical noise. To address this, re-examine the issue, inspect the installation environment, refrigerant level, weather conditions when the problem occurred, and wiring. After servicing, clear the check code logs and restart the unit.
