Probably gunked up . They can be cleaned , sometimes . Not all that expensive if it needs replacing .

The patient is a Sears compressor- really a relabeled Campbell Hausfield VT200001; two cylinder, 2 HP, 20 Gal tank. The unit pumps up and shuts down as it should. Air is leaking, from the sound of it, at the reed valves. The tank pressure drops. My guess of the moment is that the check valve on the tank is leaking. Is my logic flawed?
Thanks,
Kevin Gallimore
Instead of emitting a single, short burst of air upon shutdown, air will continue to be expelled from the unloader vavle at the pressure switch if the check valve is failed.
Nope.
You're perfectly welcome.
A lot of times you can pull the check valve out and clean it and or otherwise kludge some sort of temporary fix to get you by till a new one arrives.
I don't know about Kevin's cheap air compressor, but my cheap air compressor does not have an unloader valve -- it just has a leak on the compressor side, and a check valve.
I figured this out because when I got it the thing wouldn't start against pressure. After puzzling over it and a bit of checking, I found out that someone had taken the ball (but not the spring) out of the check valve. Fortunately, we have some little ball bearing and magnet toys; the kids did not notice one ball bearing fewer, and now my compressor works fine.
Ayup. Sure sounds like it.
So now it has an unloader? What brand of compressor?
Speaking of balls, my Gardner Denver uses a ball as an outlet valve. When I first got it the ball was somewhat corroded but a visit to my friendly auto mechanic produced a suitable replacement.
