Can inverter overheating cause the Prius A/C to stop working?

The Prius inverter has a cooling system that, if not maintained properly, can overheat. Can an overheated inverter force the A/C compressor to shut down, and how can owners prevent this issue?

Yes, overheating of the hybrid inverter can cause the A/C to stop working:

The Prius inverter is responsible for managing power between the hybrid battery, the A/C system, and other electrical components. If the inverter overheats due to insufficient cooling o r system malfunction, it can disrupt power supply to the A/C system, causing it to fail.
Prevention: Ensure regular cooling system maintenance, check the inverter coolant levels, and clean the radiator fans to avoid overheating.
