What this usually means
Intermittent cooling is commonly refrigerant leak, condenser fan, expansion valve or temperature sensor before compressor failure. Ask for pressure readings and leak-test proof before approving compressor replacement.
What to ask the workshop before approving repair
- • Show the diagnostic fault codes.
- • Show photo/video proof of the failed part.
- • Give an itemised quote for parts and labour.
- • Explain why cheaper common fixes were ruled out.
- • Use/confirm: Star Diagnostic XENTRY
- • Use/confirm: Aircon pressure gauge
This is not a final diagnosis. It is a money-saving checklist before you go workshop.
