Saw a compressor short cycling twice a second. Found the low pressure control out of calibration, made it work, though i think it should be replaced.
While setting the low pressure control (with my gauge on), i notice the pressure climbing from 10psig, to the 30psig in about 10 seconds.
Is this the soldenoid valve or the compressor valves? if it's the compressor valves, how do i know if it's suction or discharge valves? (though i recognize that both should be replaced during a rebuild)
