Theree are TWO common problems that cause this. Usually these have a compression release associated with the pressure switch. If you hear a hissing noise from around the pressure switch, this little valve may not be seating. The very common problem is actually with the main check valve for the compressor. It is often right where the pressure pipe from the compressor goes into the tank... right as a part of the fitting there. Common problems are contamination of the valve seat OR in some cases they have a soft seal moving part like Teflon or other that wears out and leaks. Rings problems are really rare. In a few cases the pumps use a diaphram and those can get damaged, but most 2 HP do not use that type of pump.

Porter Cable Pancake compressor builds pressure, but will not shut off when max pressure is achieved. Pressure switch is NOT the culprit.

Most P/C compressors shut off at 150psi. If the pressure switch is bad, the pressure will rise until the safety pops. If the safety is not opening, then most likely the cylinder / piston ring is worn to the point that pressure will not increase past safety range (cylinder could be scratched near top ). If cylinder and piston are ok, then air is leaking somewhere (check all joints with soapy water). Good luck

Ac2000b motor runs but builds no pressure in tank

Your compressor is worn out. It is repairable but you will quickly find out that the price of the rebuild kit and S+H is about the price of a new compressor at your local store.

Oil-less compressors cannot stand up to use and abuse they get like a oil compressor can but they are certainly affordable.

Thanks for your question @

most likely the regulator is shoot. But also try checking for leaks with dish soap and water in a spray bottle.

My compressor won't build pressure over 90lbs

Small leak will prevent the unit from building proper pressure. Check all connections with soapy water and repair as needed (including under cover). If no leaks are found check cylinder for scratches. Push piston to top of stroke and check walls for fine scratches. If scratched, pressure is leaking past vinyl piston ring. If no scratches or leaks, most likely reed valves, head gasket or combination of both. Easy test, with compressor running and attained 90 lbs, place finger over air intake and check for good suction (carefull could be hot) . If good suction, then air is leaking somewhere, of no suction suspect reed valves/worn cylinder, if air seems to be blowing out of intake, suspect reeds /gaskets. Good holidays

Oil covering pancake and pressure adjustments

Typically on the inside cover of the electical box it will illustrate the cut-in/cut-out controls. There should also be a fill port above the pump end of the compressor. Do you have a sight glass on the side of the compressor *(around the area of the leaking oil) usually if its coming out its due to overfilling or tipping over of the compressor.

Oil problem

All reciprocating compressors have a series of pistons that pump up and down inside their individual cylinders to compress the air to a higher pressure. This rubbing creates friction, which creates heat. In order to conserve the life of the pump, you need some type of protection. Some pumps are “splash” lubricated with oil and some have a teflon-type lining in the cylinder. Oil-less compressors are adequate for lighter use applications and have the advantage of being able to run off-level without worry, however even though they are considered low-maintenance, they tend to wear much quicker due to more heat build-up and repair costs could be extensive. Oil-lubricated compressors have the advantage of keeping the pump running cooler and lasting much longer and are built for the professional who takes pride in ownership and will maintain his equipment. However the key is to make sure the compressor sits level so the “splash”-lubrication is effective and reaches all cylinders. If run off-level, it can score the cylinder and do heavy damage over a short period of time. It is very difficult to claim warranty for the owner in this case.
