Unexpected compressor failures usually hit at the worst time — after hours, on weekends, or mid-service when stock is on the line. This practical Australian guide breaks down a simple compressor maintenance schedule, common fault symptoms (won’t start, overheating, short cycling, noisy operation), and what to check before you swap parts. You’ll also learn how relays, capacitors and overloads fail, how oil issues show up over time, and when it’s smarter (and safer) to call a licensed pro. Use it as a clear troubleshooting playbook to reduce downtime and avoid repeat failures.
