Porter Cable brand "Job Boss" constantly runs and keeps building pressure until I turn it off manually.
I have a Porter Cable brand "Job Boss" 1.6 HP 4.5 gallon oiless
air compressor. The minute I turn the compressor on it will constantly run and keeps building pressure to high levels. The only way to shut it down is to switch it to off, otherwise it would run for hours if you let it. Do you think it is a pressure switch problem?
Absolutely Jon, it sure sounds like your pressure switch is pooched. I would recommend against using the air compressor again until you get the switch replaced.
