More than likely it is a problem with the inlet control, commonly I have found wear in the throttle linkage can cause this or a faulty sump pressure sensor that is out of calibration.

SOURCE: Ingersoll Rand Air compressor loosing pressure

sounds like you have a problem with the discharge valve on the secondary cylinder, some I.R. pumps rely on the cylinder head valves to hold back tank pressure when the pump comes to a stop. the line down to the crankcase in front of the crank is a unloader valve that dumps the air pressure inside the pump to allow the next restart. I think that once you drain the tank and remove that cylinder head you will find a defective valve in the head.

WHY DOES A SM75 INGERSOLL RAND COMPRESSOR CUT OUT ON LOW PRESSURE OIL


Low oil pressure. Are you adding a lot of oil. Have you check the oil level. Switch could also be bad.

I have old Ingersoll Rand compressor type 30 model 15T serial # 243496 Blow fuss when restart ?


Probably a faulty non return check valve, when the unit reaches pressure air in the delivery pipe is vented down at the pressure switch. If the check valve is passing back this will cause the unit to try to start against a pressure causing it to pull high amps and trip. If there is a constant hiss coming from the pressure switch when the unit stops it will be the non return valve. There should be a short hiss of air when units stops If there is no hiss at all when the unit stops it could be a faulty pressure switch. If it is a quick fix would be to create a small leak on the delivery pipe to vent the line down.

When it shuts down, press DISPLAY SELECT button once and use the up down arrows to see the code just before shutdown.

HIGH AIREND TEMP

HIGH AIR PRESSURE

LOW SUMP PRESSURE

PRESSURE OR TEMP SENSOR FAIL

CHECK MOTOR ROTATION

MOTOR OVERLOAD

FAN MOTOR OVERLOAD

I am assuming this has a Intellisys controller.
