The IPM module is the inverter module which controls the speed of the compressor and the outdoor fan - this is what makes the unit energy efficient.
To fix the problem with the error code F5, check the following to see if the IPM needs replacing:
- Check the connections between the compressor and IPM module are clean and tight
- Check the IPM module is firmly screwed down to the PCB case
- An engineer will be needed to check the refrigerant level, low gas can cause the compressor to get hot and send wrong signals back to the compressor
note: the 9K and 12K systems don't use a seperate IPM module as its built onto the main PCB. The 18K and 24K systems use a seperate IPM module which is mounted next to the main PCB.
If all of the above is good - the connections are clean and tight, the refrigerant is at the right level - then the IPM module needs replacing.
