SOURCE: Craftsman air compressor 1 HP 12 gal 125 psi

this is probably an "oilless" compressor, it has "piston" with a thin ring of leatherlike material acting as a piston ring, the "cylinder" is an aluminum sleeve - what usually happens is the cylinder gets scratched from dirt or just wear or the leather ring deteriorates, that's why it will go only so far - the only fix for this is to replace the cylinder and the piston

SOURCE: i have craftsman air compressor model number919-167310

is this new, has it ever run? perhaps the breaker isn't large enough for the units required amperage, maybe the breaker is just bad. Have you tried different recepts? Check the nameplate for the amp requirements and make sure the breaker is big enough

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.

Poor air compression


I would guess from the info supplied that the pressure switch is shutting it down at 125. Most piston type compressor only pump a max. of 175 unless it is a special high pressure unit. Also it may be shutting down on high amps, high temp etc.However with all that said Piston units are positive displacement, meanning that it should pump until something gives. Start your unit, close the discharge air valve and see what it pumps up to. May have to adjust pressure switch to get over 125. If unit runs and runs and just will not go over 125, you probably have a valve going bad. Do you have a safety lifting. if so another indication of a bad valve.

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.

Compressor shuts off before reaching max pressure


Yes,but if the max is 125 you don't want to increase it above 110 and set off the pressure relief valve.
