Craftsmen 1HP 125psi compressor problem

This compressor I have used about 5 times adn now it will not compress past 20 psi. It used to kick the motor on compress and then kick into high and get up to 100 or so and that was sufficiant, but now it won't. What could possibly be the problem? I'm stumped and I don't want to resort to throwing it out. Any help?

    Well my head definitely has not blown. So rule that out. That would be obvious and I inspected it today and the head is in great condition. I did check the leads though and and cleaned them up. I also checked the cut in and out settings. I turned it on for the first time in months and it kicked up to high and reached 120psi no problem. I emptied it and tried it 2 more times and reached 120psi every time. Do you think the read valves did get stuck?

    As for me buying it, I bought it off of my father in law and he used it about 2 times. No taking it back at this point. It is still in emaculate condition though and looks like the problem fixed itself untill the next time, hope not!! Maybe it was the leed valves.

    They may have gotten frozen like you said. It was getting cold around that time. Thanks for your help.

Either the reed valves are stuck or the piston seal blew. You can rebuild the head with a kit or bring it back to sears. When did you buy it?

    Once is a while they get out of place or could have been frozen depending on your location. Good luck

Most people recommend replacing the motor capacitor in this situation, since a faulty cap will reduce the starting torque. But in my case the check valve was the culprit - there was too much back pressure on the head.

My craftsman air compressor #919176820 2 HP 12 gallon 200 max psi will not compress over 125 psi


If your compressor is oil-less type, most likely pressure is leaking past piston ring. To verify, remove cover to expose bottom of cylinder (unplug compressor and let out all air). With flashlight, examine the upper-most part of the cylinder (turn motor by hand till piston is at top of stroke). If top of cylinder is scratched, then pressure is leaking past.
For many years now, stores are in a race to have more HP and PSI to attract customers. Customer is really the loser because components used to make the units can not handle the higher pressure. Normally small 115v compressors are set to cut out at 125psi and larger two stage units will cut out at 160psi. Small compressor set to 200psi makes for short lived compressor. Could be compared to driving your car at 100mph all day every day. Longest life is attained when unit is being used at about 60 to 75 % of capacity.
To allow your compressor to reach cutout pressure and keep working for a while, lower cutout to 120psi (pressure switch may be adjustable). To restore to 200psi, replace cylinder/ ring.
If your compressor is oil type, suspect leaking reed valves.

I have an Ingersoll Rand T30 10 HP compressor that runs OK and will bulid up 150 psi without any problems. But when the pressure drops enough to kick the pressure switch, the motor won't start. just tries...


When the compressor comes up to pressure and kicks off, you should normally hear a gasp of air escaping. That gasp is the release of pressure from the compressor itself - not the tank, and it is supposed to get released so that the compressor can restart without being preloaded with compressed air. My guess is that the gasp is not happening. It is probably some debris or a gummy mechanism. The mechanism is supposed to be triggered by the same mechanism that shuts off the motor.

No air pressure past 60PSI on a 125PSI Campbell Hausfield WL61110


Your comperssor is oilless type and suffers from short cylinder / piston life. When the compressor no longer reaches cycle pressure the cylinder / piston should be replaced. These parts are available at www.chpower.com I believe that the part number is wl210300aj. Not expensive, enjoy.
