You need to determine what type of air compressor it is? Rotary screw, reciprocating or something else. Most questions on this site are for reciprocating compressors which is the type that has pistons like an engine in a car. The next step would be to determine if the air compressor is driven by an electric motor or a gasoline engine. Your question appears to be incomplete, I assume you are explaining the air compressor comes on, (assuming the air compressor is driven by an electric motor) meaning the electric motor starts up & is running but the air compressor is not build any air pressure in the tank? If this is accurate, the next step would be to determine how the motor or engine drives the compressor? Most likely it's belt driven. You need to confirm the drive belt has not broken and that it's on the pulleys or sheaves, then confirm the belt is turning the air compressor itself. If this is the case then your air compressor could have a problem with the valves, pistons, piston rings or controls. The majority of problems I read about have to do with small air compressors driven by electric motors. If you hear air pressure when the compressor is running, you could have something very simple like the drain on the tank was left open and the pressure cannot build up because it is leaking out. Closing the drain would be the solution to that. It could be an air line or fitting leaking too much air, preventing the compressor from building pressure. If that isn't the case and the machine has been working fine and this is something that happened all of a sudden, there could be a broken valve insid the air compressor. If this Is not a reciprocating air compressor, then the troubleshooting steps would be very different. You would still need to confirm the motor is driving the air compressor but you could have a more complicated problem if this is an industrial rotary screw air compressor. I find most of my good answers in the manuals that come with the equipment. I would recommend beginning with the manufactures website and or calling them for technical support. I do it all the time. It's super helpful.

In the owners information your compressor takes the 1 bottle of IR oil that comes with it. If you have a local tractor supply company or another company who carries IR you might check with them, it is the only oil i would recommend for your unit.
