Power module over current detected by hardware
â–¶ How to fix
Check the three phase cable and compressor motor terminal for short circuit among the phases. If no short circuit, Check for compressor high pressure operation or stalling or blocked operation. This can be done by checking the refrigerant circuit for blocks or faulty valves.
