Troubleshooting your Realcraft air compressor when it won't start with a full air tank

If the compressor won't restart after it fills the air tank, the check valve is likely stuck open. The check valve prevents tank air from back flowing to the pump. The stuck-open check valve causes high pump head pressure, preventing the compressor from restarting. Test the check valve by shutting off the compressor and pulling the ring on the safety valve to bleed the air from the air tank until it's empty. Turn on the compressor to fill the air tank. Bleed air out of the tank to reach the cut-in pressure so the pressure switch attempts to restart the motor to refill the air tank. If the compressor won't start with air in the tank, replace the check valve.

Common Realcraft air compressor repair parts

  • Check valve. The check valve prevents tank air from back flowing to the pump. A failed check valve will apply high air pressure to the head of the pump preventing the motor from restarting once the tank has filled. If the motor starts when the tank is empty of air but won't restart when the tank is full, replace the check valve.
  • Safety valve. The safety valve pops open to relieve excessive air pressure if the pressure switch fails to shut off the air compressor at the cut-out pressure setting. Replace the safety valve if it leaks or pops open at normal operating pressure.
  • Air tank. Don't try to fix a leaking air compressor tank. Replace the tank if it leaks air.
  • Motor. The motor drives the piston or pistons that compress the air in the pump. Replace the motor if it doesn't run when it gets electrical current and the air tank is empty.
