The IPM module is the inverter module which control the speed of the compressor and the outdoor fan, this is what makes the unit energy efficient.
- 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.
- If the connections are clean and tight and the refrigerant is at the right level then the IPM module needs replacing.
notes:
- The 9K and 12K systems don't use a separate IPM module as it's built onto the main PCB
- The 18K and 24K systems use a separate IPM module which is mounted next to the main PCB

ANY WIRING OR CLEANING OF CONNECTIONS REQUIRE THE POWER TO BE ISOLATED BEFORE WORKS COMMENCE.
