Compressor cuts on and off and not pressure

My compressor cuts on and off with no pressure for the air pressure to work.I have a paasche d500.

Hi Lisa. Have a look at the page linked from the Pressure Switch button on the Nav bar.

If your tank pressure is below the pressure switch cut in setting, and the compressor starts and stops at that pressure level with no tank pressure increase, that points to a questionable pressure switch to me.

Cheers,

Bill

Starts to build air then shuts down

Starts to build air... for a minute, two, what pressure level in the tank, shuts down how... a bit more info would be useful.

If the pressure is building in the tank, and the unit shuts off (not blowing a fuse) before reaching the normal cut out pressure, and the unloader valve dumps air when the compressor shuts off, then your pressure switch is either set wrong, or is failing.

compressor operates intermittently

by norman Matkin

When starting from zero the unit would charge to max.,i.e 125 psi and shut off as expected. But when the pressure reached 90psi the motor sputtered and would not restart and the circuit brkr popped. But if I bled the tank to zero the compressor charged up to normal max pressure but it would not automatically restart. I replaced the compression switch but things did not change. Also when the motor did cut off air was expelled as expected.

Hi Norman.

From zero PSI, your compressor runs perfectly up to 125 PSI and stops at the normal cut out pressure level?

Then, you start using air, the pressure drops to 90 PSI, and this is the normal cut in pressure and your compressor tries to start at that pressure, is that correct?

If it were my compressor, and these summaries are correct, I would replace the pressure switch, and make doubly sure that it was wired correctly.

Cheers,

Bill
