Panasonic Air Conditioner H30 error code

The H30 error means your Panasonic air conditioner detected a fault with the outdoor discharge pipe temperature sensor. This sensor monitors the temperature of the hot refrigerant gas leaving the compressor through the discharge pipe — a critical safety measurement. When it fails the unit cannot protect the compressor from overheating and stops operating. A qualified technician will need to inspect and replace the sensor.
Common causes
