Mine had the same problem.
One of the reed valves in the head had broken off due to metal fatigue. Take off black plastic housing with 5 screws along the bottom and one bolt under the handle (the front only). Unscrew the four allen headed screws on top of the compressor. Unscrew the discharge line from the head. You'll need part # AB-A640050 which is the valve plate assy. and possibly AB-9007012 which is the intake valve located in the top of the piston (if damaged). About $18 including shipping from Bostitch.

    Had the same extact problem with my compressor. It would get as far as 80 psi and not go up any further and the motor kept running. LaMojoe was correct. The metal was erroded on the valve plate assembly and thus allowing air to flow through.

Turn the gauge up to allow more air or try checking the drain plug on bottom of tank to see if it tight.
If these 2 don't fix it check all connections for leaks.

Well picked this up at a auction and i need to get some part like the air filter and the air filter holder plus a new dip stckalso the manual.. plus i need to know why it won't charge past 50 psi


compressors that do not go past 50 psi generally have a failed poppet valve or reed valve in the heads of the compressor
talk with a compressor repair shop for the filters and housings and where you can get the valves and gaskets

Why will my bostitch pancake compressor 240 psi tank 180 regulator that the guages will not show building pressure


Hi, There are different posibilities. I would need more information. Was it always like that? Does the guage on the main tank and the guage on the regulator both not show more than 20psi? When the auto shut-off is triggered do you feel there is more than 20 psi in the tank?

My sears air compressor model 919.156781 will not pump up past 40 psi , then motor then compressor stalls and motor gets hot , have to unplug . I have had the motor checked


When it gets to 40 psi turn it off and see if you hear air leaking down from somewhere....if so listen and feel around the edges of the compressor head. If you hear or feel air leaking there you may need to replace a head gasket.

Searching for fenwai pressure control fw 10


If your compressor is a piston compressor, try cleaning the check valve which comes from the pressure switch to the tank (it has a little spring and a rubber/plastic valve inside)
Otherwise check to see if it is sucking air in properly, (whilst it is running, remove the air filter, and very quickly put your hand over the air intake to see if it is sucking whilst it is at 20 psi, if not, then it may be that the valves in the head maybe either broken or not seating properly

If it is not a piston compressor, then it maybe the MPV needing some attention

Hope that helps

My compressor will not go over 20 psi i have a craftsman 921 4 gal 125 psi compressor and it will not build past 20 psi i do not know how to get to the pistons and stuff what do i do?


The problem with compressors not building pressure is usually a bad pressure switch or bad regulator. Does the motor shut off at 20psi or does it continue running and not build pressure? If the motor continues to run with no increase in pressure, the you should go over the machine looking for air leaks from your regulator back all the way to the motor. Any air leak while the compressor is running can cause the pressure to "peak" way before the intended shutoff that it is regulated to.

Would not pump past 90 pounds psi, now does not pump at all


Might be a switch failure. Usually the switches will have an integrated pressure switch to shut the compressor off when the holding tank reaches its max psi. When the switch starts to malfunction, it will shut the compressor off early and eventually fail due to overheating of the internal components of the switch.
