Compressor Fault Codes and Repair Guides
Air and refrigeration compressor fault-code guides, sensor checks, shutdown causes, and replacement-part decision pages.
Common compressor fault patterns
- High temperature, low oil, pressure switch, overload, and phase-loss shutdowns.
- Drive, controller, transducer, separator, and filter faults on rotary-screw systems.
- Refrigeration compressor safeties, condenser fan issues, and controller alarm histories.
Compressor repair decision checks
- Record the exact controller alarm and operating hours before clearing faults.
- Check filters, cooling airflow, oil level, and voltage balance before replacing sensors.
- Route repeated overload, motor, or airend failures to service quotes instead of parts-only repair.
