You either need to clean the intake & out flow seats at the main flapper or replace the flappers. The other choice would be a stuck open regulator or drain.

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.

I HAVE A CRAFTSMAN 1 HP 12 GAL AIR COMPRESSOR THAT WILL ONLY BUILD 20 PSI THE COMPRESSOR ONLY HAS 1.5 HRS RUN TIME ANY SUGESTIONS


hi there, if the compressor built up a 20 psig and run at 1.5 hrs.then stop.check the pressure switch the differential pressure cut in and cut out limit.adjust the cut out to the corresponding cut out pressure you want but not exceed to the designed pressure tank..this will be done on adjusting cut out pressure screw mounted inside the pressure switch.follow the instruction on the manuals adjusting pressure switch.the run time correspond to the cut out limit of the pressure switch. rate my fix if your satisfied thank a lot.

No air pressure


If your motor is running and the pressure is not building it is either the valve plate or the compression ring. Check both for damage.

WILL NOT BUILD UP AIR PRESSURE PAST 20 LBS.


Check to see if air is leaking past 'pressure relief' valve. It's probably leaking and that's where all the air is going.

EC-12 runs but only builds to 35 psi and continues to run


It looks like there might be a knob which sets the max air pressure coming from the compressor. If there is one, this may have been turned down.

There are usually 3 pressure settings on an electric compressor. Compressor max, pressure switch cut on, and pressure switch cut off.
