Hi, Fault Code 65 is a problem with the Inverter PCB heat sink thermistor for the heat sink on the outdoor unit PCB, unplug the thermistor from the PCB and check its resistance. Fault Code 52, this fault code indicates a communication error between the Main and Sub micom (CPU’s) on the outdoor unit main PCB. Check for evidence of damage, if none found reset power, if fault reappears replace pcb.
