Your location may not have a good constant supply of electricity and you are experiencing variable voltage surges. I would suggest that you get a voltage meter and check the voltage to the motor while it is running under load. It needs to remain constant.

hi there,
well,if your air compressor was shut off this due to pressure switch w/c auto switch off your compressor,the pressure switch acquired already the cut off pressure.if the pressure goes down the cut in set up reached it will start your compressor
to run.
regarding oil spillage when shutting down check the oil level on the sight glass of crankcase
a red line indicate oil should not exceed on that level line,if the oil exceed try to drain oil.,on the side bottom of engine there is a drain plug.until on limit level .,besure that machine is shut off/breaker is off.have a nice day don't forget to rate me,thank's

Has the power supply been checked? It should reset itself when proper supply power is restored.

possibly the check valve but most compressors shut off at 100 psi
it could be that the motor is not of sufficient capacity to go to a higher pressure and that is why it appears to be struggling

Hi my name is Luke and I bought a Ingersoll-Rand 7.5 compressor and won’t start. I noticed it has a wire not connected on the capacitors it’s a blue wire that reads t5 v3 there’s a capacitor with open prong before two start caps and another capacitor after the two start caps , at least that’s what it reads on caps unless they have been wired wrong , being that I would think the start up caps should be wired first from powers supply box , want to know where it went Before I went trying to change capacitors and there’s 5 here’s a pic

I don't know if your unit is exposed to the direct sun light if it is I suggest you create some shade , or if this this unit is enclosed is not getting enough air flow to keep cool.
( this air flow helps to stabilized the sensor that stop and start the compressor )

check and test the capacitor or power source --to long or not correct extension cord --to small a breaker for load start

Does it have separate compressors on tank?. You probably need to adjust cut in and cut out pressure switch. I have seen several air delivery systems that utilize 2 separate compressors, this allowed a backup if the one online failed. The units had unloader valves and the compressor never stops running. A call for air pressure would close unloader valves and unit would pump up and the the valves would unload.

Ingersoll Rand likes you to buy their all season select oil for their air compressors, most piston air compressors use an R+O 100 oil it is equivalent to n SAE 30 wt oil.

naturally there will be as it is called piston to cylinder clearance
you can get rings from e-bay if you know the diameter of the bore and the ring width
indicates that the poppet /reed valves are worn and not seal off properly or the head gasket/s are leaking
