If the pressure reading in the LD1 display does not change, the affected pressure sensor is faulty.
What to do if my Mitsubishi Electric CMB-P1010 Air Conditioner pressure is too high?
If the pressure is 3.14MPa (in the case of the low pressure sensor, 0.98MPa) or higher, the MAIN board is faulty.
What to do if my Mitsubishi Electric CMB-P1010 Air Conditioner pressure sensor shows 3.14MPa?
If the pressure according to the LD1 display is 3.14MPa (in the case of the low pressure sensor, 0.98MPa) or higher, the affected pressure sensor is faulty.
What to do if my Mitsubishi Electric Air Conditioner pressure is 0~0.098MPa?
If the pressure is 0~0.098MPa on the LD1 display, the affected pressure sensor is faulty.
Why is the internal pressure dropping in my Mitsubishi Electric CMB-P1010 Air Conditioner?
If the gauge pressure is 0~0.098MPa, it indicates the internal pressure is dropping due to gas leakage. Check for failure by comparing the sensing pressure.
What to do if my Mitsubishi Electric Air Conditioner pressure sensors differ by more than 0.098MPa?
If the difference between the two pressures exceeds 0.098MPa, the affected pressure sensor is faulty (deteriorating performance).
