CH Model HJ300200 quits running before reaching 150psi
I have a Campbell Hausfeld 20 gal upright oilless air compressor, model HJ300200. 120V that is a 200 psi compressor.
Compressor starts up fine and builds pressure, but stops running after a few mins.
It will build up to different pressures, but never to the 150psi that it's set at.
When it stops, I can see the contacts on the pressure switch are still in the closed position, which leads me to believe that the pressure switch is fine.
I have used this compressor very little and bought it new. What could be the problem?
