AC Compressor Failure

I recall a remarkably similar issue with my Winner, though I don't remember the build year. The symptoms are virtually identical. I'd suggest the pressure switch as a potential cause. Have you checked the A/C system's pressure readings? What sensor data did you observe during the fault?

Regarding the pressure switch, what specific pressure readings did you see when your system had these symptoms? Also, did you confirm if undervoltage was the root cause, or just a symptom of a deeper problem in the A/C system's control?

I don't have the exact pressure readings. The data showed an irregularity preventing the compressor from engaging. Undervoltage was suspected, but a definitive diagnosis was challenging without specialized equipment. Given the symptoms and your technical skill, a workshop with diagnostic tools might be best. I ended up going that route.

Thanks for the help. I sought professional diagnostics. The workshop confirmed the undervoltage. Repair cost was 240€. Your suggestion to check the pressure switch was insightful and sped up the diagnosis.
