Question about Campbell Hausfeld 26 - Gallon Air Compressor
Here are a few things to check, you may have already checked some of these.
*Electricity...Compressors will run best with full 115Vot 15AMP/Or 220V electrical supply from a circuit, over the shortest electrical cord as possible.
*Air Leaks..Place your ear close to the compressor and listen for air leaking, if you hear air that is not normal and means you have to locate and repair whatever it is that is leaking.
*Check the air unloader valve... The air unloader valve will blown out air when you turned off the compressor, that is normal.
But it should not have air leaking out of it all of the time. If so then it is faulty and in need of repair/replacement.
*Valves...If either the intake or exaust valves fail, breaks, or fails to seat, then your compressor will run 24 hours a day and never build up to the correct pressure for shut-off.
*Gaskets...Check to see if your gaskets have failed.
You could have a gasket failure between the pistons and you will never know it because it shows no external air leak.
If this situation happens then the air will only cycle between cylinders and never build up the correct air pressure.
One way to check the gasket is remove the air filter, then put your hand over the intake.
If correct then it will **** you hand against the intake.
If the valve or valves have failed then you will feel the air sucking in and blowing out.
*Piston Rings and Cylinder...The piston rings could be stuck,broken, or worn and not allowing the correct pressure to build up in your tank.
A worn cylinder will also contribute to the problem of pressure build-up.
*Pressure Switch...Check for air leaks at the pressure switch, it has a rubber diaphram that can fail and leak air out of the system.

The pump is probably not shutting off, because the pressure is not building up. When the pressure would built up, the compressor should stop automatically.
So, why is the compressor not building any pressure?
It could be many things, like Bud above me said. But MOST of the time, it is either a broken inlet valve, broken outlet valve, blown internal gasket or a unloader that keeps open.
- Broken inlet valve is easy to detect: if you feel air coming out of the inlet filter, it is broken.
- Broken outlet valve and blown gasket is harder to detect: you probably need to remove the cylinder head to check it.
- Leaking unloader valve is easy: if there is air coming out while the compressor is running, it is leaking. It should only blow off air when the compressor stops.
