45 IPM fault
1. Reconnect the wiring of the
sensor for the expansion valve
B (thick tube);
2. Replace the sensor for the
expansion valve D (thick tube);
3. Replace the outdoor control

See attached "analysis of the
driving board fault".
There are many reasons for this
failure, If you need further analysis ,
fault code of the driver board is
needed by watching the driver board
fault led. Analysis can be further to
know why and how to operate.
Specific see table 5, table 6.
