Question about Craftsman Air Tools & Compressors

Open Question

My Craftsman air compressor #919 167 37, 17 gal, 1.1hp does not work. The sound is something more like a wet-vac, and I believe it to be the relief valve. I don't have an owners' manual, and need to know what type of bolts, screws, or whatever is holding on the top cover. They are recessed too far inside to see. Also how do I get an owners' manual?

SOURCE: My craftsman 3 gal. air compressor, 921.153101 won't compress air

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: need to replace drain valve

The "welded nut" is the pipe fitting into which the drain valve or drain plug is screwed. It's usually brass and the valve or plug can be obtained through Sears or possibly and good harwarde store. Be sure to use pipe sealing compound or teflon tape on the threads when you re-install the valve or plug.

NOTE - THE AIR MUST BE DRAINED FROM THE TANK BEFORE REMOVING THE VALVE OR PLUG. ALSO, POWER SHOULD BE DISCONNECTED FROM THE COMPRESSOR!

SOURCE: The compressor relief valve keeps popping, compressor runs

What pressure is it popping off at? You might have to adjust the pressure switch to a lower setting.

SOURCE: HUSKY PRO AIR COMPRESSOR 30 GAL I NEED TO KNOW HOW

Depends on what plan it was made in...
If you have the glass type sight... Only to the max you can see (top of site), then run it for a few mins, let it sit for a few more mins then add more if the level is near the bottom of the sight glass.

If it's the dipstick model that pushed in, there will be an upper and a lower level mark (holes, or checkered section) Keep it between the top and bottom marks.

Finally if it's the older screw-in type, remove the dipstick and wipe it. Set it back in BUT don't screw it in. Keep within the range on the dipstick from that position. Then of course screw it back in/

Good luck

Leaking around Pressure Switch. Ordered & replaced switch but still leaking


Some pressure switches have a valve that reliefs the compressor head pressure when the motor stops and closes the head pressure relief valve when the motor runs.
There is a check valve that keeps air pressure from coming back to the compressor head and the relief valve.
I think the check valve is leaking tank pressure to the relief valve and compressor head.
The check valve is where the pressure switch mounts on to and it mounts threaded on to the compressor tank.
Try replacing the check valve

Compressor was airing up to pressure when it sounded like it blew out a pop off valve or diaphram. Now it sounds like it has a large leak and does not build up pressure at all.


Turn on the compressor and look for the air leak. It could be a relief valve or a connecting hose or tube. You must locate the leak then see if it is a part that can be replaced.

Compressor not building enough pressure.only 5lbs.


It seems that your cut off switch or your relief valve is not working. If the cut off switch stops the compressor at 5psi instead of 100/120, then the switch is defective. If the relief valve operates (loud whooshing sound and the compressor keeps running), then the relief valve needs replacing. Normally the relief valve wears out first as the seal gets worn or the spring fails.

Craftsman 1 HP 4 Gal air compressor runs and sounds like the air pump is working but no pressure is building up


Cold weather will freeze the water the compressor normally makes and this can prevent the switch diaphragm from releasing.... also drain the tank

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.

Compessor trips circuit


IT SOUNDS LIKE YOUR COMPRESSOR IS NOT UNLOADING WHEN IT SHUTS DOWN. YOU SHOULD HEAR AN AIR RELIEF SOUND TYPICALLY ON THE SIDE OF THE PRESSURE SWITCH WHEN IT SHUTS DOWN. ITS A SMALL VALVE WITH A TIRE VALVE THAT THE LEVER HITS AND RELIEVES THE PRESSURE FROM THE DISCHARGE LINE AND THE TOP OF THE PISTON.

YOUR CHECK VALVE COULD BE BAD LETTING PRESSURE BACK UP BUT IT WOULD BE BLOWING AIR OUT ALL THE TIME WHEN SHUT DOWN.

IF YOU THINK THE VALVE OR SWITCH IS WORKING AND WANT TO CHECK IT, LET THE COMPRESSOR BUILD UP AND SHUT DOWN, LISTEN FOR THE AIR RELIEF,IF IT DOESNT THEN CRACK THE DISCHARGE LINE AND SEE IF THERES ANY PRESSURE, MANUALLY RELIEVE THE PRESSURE THEN USE SOME AIR AND SEE WHAT HAPPENS. REPAIR VALVE ON THE SIDE OR CHANGE PRESSURE SWITCH $30-40.00. HOPE THIS HELPS. PLEASE REPLY. JODY
