SOURCE: Mastercraft 2.0 hp air compressor will not build up over 25 psi

sounds like a bad or broken valves in the head. crankcase needs a vent which is sometimes a small hole drilled into the oil fill plug and will normally blow some air out the vent while it runs

Probably the check valve has failed. It apparently is where the pipe goes into the tank from the compressor.

SOURCE: I have a Central Pneumatic,

If air leaks when motor is off, fault most likely in-tank check valve. Follow discharge air line from pump to tank. Brass/steel valve at tank is the check valve. Remove hose to valve and check for leak. Replace as needed. If air is leaking while motor is running fault could be reed valves in head. Faulty reed valves in head, or torn head gaskets will cause very hot discharge air and tank will most likely never fill to shut off (or take a very long time to fill)

I have a Central Pneumatic 38898 pancake compressor that will not shut off when the pressure reaches pre-set PSI. I have replaced the pressure switch but to no avail...HELP!!


There must be a blockage on the fitting where the pressure switch goes in that stops the air pressure from reaching the regulator. Try taking the switch off and turn the compressor on and see if air comes out the hole

Central pnematic compressors, will not build up air


Use soapy water to check for air leaks. Can also check piston ring and valves. Make sure engine is driving the compressor.

Why does the safety valve go off before the pressure switch on a porter cable 80 gal air compressor


The maximum pressure on most small compressors is 10 bar or 1000kpa which is about 145 psi in the old language most safety valves are set to 150 psi. I suggest you get some one to reduce the pressure switch setting. Running a compressor at elevated pressures does not give you any more air. A reasonable pressure for small compressors is 120 psi

Compressor runs but the air bleeds out think it might be stuck reed


If your compressor reaches the cut-out pressure (or very close) , most likely not reed valves. Usually air leaking when compressor is shut off is result of leaking check valve at the tank. Look for brass valve and remove. Somtimes the valve is repairable if debris is keeping valve open. Clean or replace as needed.

Craftsman 3 gal., 1.5 hp air compressor: won't auto shut off, builds only 40 lbs pressure, air leaks from the 2 holes in oil filler cap?


The compressor will not auto shut off until it reaches the preset pressure which is usually around 100-130 psi - your problem is leakage of air from the oil filler cap suggesting that you have a failed internal valve.

The compressor only reach 50 PSI.


Does the compressor continue to run but not build more pressure? In which case it is an air leak most likely, or does the compressor shut off at 50 PSI? In which case it is mose likely the pressure switch. If it is an air leak you can un-screw the guage and coat with putty or teflon tape and reinstall to clog the leak around the threads..
