This error is signifying a fault between the compressor and external PCB.
To fix the error code you need to do the following:
- Check the connections between the compressor & PCB and clean and tight
- Check for any damage to the PCB, burn marks will show a faulty PCB. Replace the PCB if faulty
- An engineer will be required to check the refrigerant in the system is at the correct level, this error code normally appears when the system has no gas and the compressor has burnt out. A new compressor/outdoor unit is required.
note: the compressor is connected to the IPM module on the 18K and 24K units. It's connected to the main PCB on the 9K and 12K units.
