Speedaire Compressor starts out slow and then starts to picksup to normal.
My Speedaire air compressor (60 gal tank, hard wired 220v supposedly 5 HP motor) starts out running slow for probably less than a minute, then picks up to normal speed.
When pressure switch shut off compressor at 150 psi and after hearing the hiss of air, I removed the tubing from the cylinder head and had no air, which I think would mean the check valve is operating correctly.
Could this be one of the motor capacitor's bad or what other troubleshooting do I need to do? Any help would be appreciated. Thanks Charles
