    Mine won't compress air beyond 20psi. I took the head off and the gasket was gone between the two sections of the head. I replaced, but it still won't compress air.

    I may have something in backwards.

I WOULD TRY DISCONNECTING THE PIPING FROM THE HEAD DOWN TO THE TANK AND SEE IF ITS BLOWING AIR. COULD THE COMPRESSOR BE RUNNING BACKWARDS - YOU WOULD HAVE HAD TO CHANGE THE WIRING IN THE MOTOR.
VALVES IN THE HEAD COULD ALSO BE BROKEN. YOU CAN REMOVE THE INTAKE AND IT SHOULD **** YOUR FINGERS AT THE OPENING. HOPE THIS HELPS.

SOURCE: what kind of oil do i need for a craftman 1 hp 3

For warm climate, use 30wt non detergent oil (lowest price $3). Med priced oil ($5), use compessor oil sold at Lowes or any major center store including Wal Mart. Compressor oil is special blend for higher temperature range (continuous use). High price oil, synthetic compressor oil works for heavy duty use under severe conditions (also sold at major lumber centers, cost about $8~18).
For lite duty, any oil that you have handy will work fine (check oil before every use). Good luck

I have a 1HP/7 1/2 gal. Craftman air compressor( about 20 years old). I was using it to spray paint lawn chairs. The compressor stopped. I was to use it the next morning but for only a short time and it...


1) Check that it is not already at full pressure
2) Check that you have power coming in to the switch (20 year old power cord)
3) Bypass the switch and, briefly, plug it in.
4) Look for a fuse or breaker.
5) With the motor leads disconnected from the switch, check that you have resistance across the motor (0 ohms would be bad).

If you are not comfortable doing any part of this, don't. Check with friends & neighbors for a reputable local appliance repair company.

1 hp 3gal craftsman compressor will only build up to 20lbs pressure in tank. how much compression should single cyl have on compression stroke?


A piston in any engine should be around 100 psi I would guess. A Chevy 350 used to be around 150 psi. An air compressor that only pumps enough air to reach 20psi is obviously too low on compression. Nailers and the like need 80 or more psi. The intake valves may be shot, the unloader might be stuck or piston rings are worn.

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.

No air output, but motor runs.


check your popoff valve first. it is the valve with the ring hanging on it. You will hear the air rushing.

If you don't hear any air rushing, you may have fried the piston rings or broke/chipped the piston(not your fault)..especially with oiless compressors

This sounds like a pressure switch failure. follow the power cord to where it enters the compressor and the switch should be there. you should be able to order a new one through sears service center. Good luck.

Know tank pressure


"no matter how long the compressor runs" If it's not connected to any high volume consuming devices, and that no leak has been detected...then either an head valve (checkvalve) , severed motor shaft, nor the piston/diaphragm is defective. If it does stop after a few minutes the gauge is surely defective
