Compressor won't start Power issue, pressure switch fault, thermal overload Check power supply, reset thermal overload, check pressure switch
Low pressure output Air leaks, worn piston rings, faulty check valve Check for leaks, inspect check valve, test pressure switch
Excessive noise Loose components, worn bearings, piston slap Tighten all fasteners, check motor bearings, inspect piston
Air leaks Faulty fittings, damaged hose, bad seals Check all connections, replace damaged hoses, inspect seals
Overheating Dirty cooling fins, low oil (if applicable), excessive cycling Clean cooling fins, check oil level, allow proper cool-down
Moisture in air High humidity, inadequate draining, no moisture trap Drain tank regularly, install moisture trap, reduce humidity

Maintenance Schedule

  • Daily: Drain moisture from tank, check for leaks
  • Weekly: Inspect hoses and fittings, clean air filter
