I can't figure this one out. When my supply air pressure gets down to 80lbs the compressor turns on like it is supposed to but only runs for about 10 seconds then shuts off. I can hear and feel the contactor and the pressure switch working. In about 10 minutes it repeats that same cycle.
The way I think it is supposed to work is when it gets down to 80lbs the compressor is supposed to come on and run until it gets up to 100lbs and then shuts off. Not turning back on until it get's down to 80lbs again.
I have replaced the pressure switch, check valves and relief valves but I don't know what else to try.
Any ideas?
