OK, I need help - all you air compressor experts.
My 4 Gal pancake oilless compressor, Sears Craftsman "Professional" (black model), when I turn it on the motor just spins, sounds completely unloaded, when I unplug it, it coasts for a while to a stop. No air pressure, of course.
I haven't taken anything apart yet, the manual has a trouble shooting section but that symptom is not listed. I'm not real familiar with these devices.
What does it sound like? I would assume the induction motor is direct coupled to the compressor pump reciprocating cylinder. Is there a linkage that broke? A shear pin or something to prevent locking up the motor?
Or maybe the piston is actually pumping but with no load (air inlet blocked, check valve problem, what?)
Your help appreciated.
(maybe I should head on down to Rockler and get the $129 PC pancake compressor and brad nailer combo for $129...)
