Craftsman 919.167242 compressor not shutting off and I replaced pressure switch
(Ponchatoula, LA, USA)
I have a Craftsman 919.167242 air compressor that will not shutoff.
I've took it apart cleaned everything resealed all threaded areas and have replaced the pressure switch with a new switch from sears.
There are no leaks.
The compressor will only shutoff after the tank PSI reaches 150.
The regulator gauge shows the same or close to the same PSI as the tank and will not show a lower reading no matter how much I turn down (unscrew) the regulator.
However the regulator will bleed air when the turned down to a lower level presumably the set regulator PSI. Could I have a malfunctioning regulator or pressure gauge or did I get a faulty Pressure Switch? Thanks in advanced
Paul, what is the high pressure cut out of your pressure switch. 150 PSI does not sound unreasonable to me, and if it is shutting of consistently at that 150 PSI, I would guess that the switch is fine, and that's the cut out pressure setting for it.
If you are turning the regulator pressure setting down, and you have air in the line downstream of it in, for example, an air hose, and the regulator bleeds off that higher pressure air as you turn the pressure down (as it is supposed to)then I would guess your gauge is pooched.
craftsman 20 gal.air compressor won't start

My brotherinlaw works for sears and someone bought a new 20 gal. air compressor.they pluged it in and a spark came from the motor.it did not start.so they took it back.that is the history of this compressor.
Now I got this compressor for free from sears and tested a few things.it has 120V. at the psi sw.it has 120V at both sides of the capacitors.the breaker has 120V at both sides.not a peep comes from the motor.remember this is a brand new compressor.what am I missing.please help. thanks Darrell.
You got a free, broken, air compressor, Darrell! :-)
Could have been the start, run or motor that is causing the non-start now. If this were my compressor, I would get them all checked.
