If it is supposed to shut down automatically. Your pressure contol switch may have gone bad.
If it is rated to go higher then you may have bad compressor rings that won't allow it to go above 110.

Why my air compressor want shut off after building up pressure


If it is building up to the full rated pressure and there are no air leaks in the hoses then it is most likely the pressure switch. It is item 111 in this parts diagram.

Compressors


The pressure regulator on an air compressor is designed to let the pump motor run until the pressure in the tanks reaches their safe level. While you are using the air the pressure drops in the tanks until it reaches the level where the pressure switch turns the motor on again and refills the tanks to their rated level. The pressure where these two things happen is usually with in ten psi above or below the rated levels because few regulators are so precise and are affected by temperature that they turn and off exactly at the rated pressures. If a pressure regulator is damaged or broken it is possible for the tank to either reach unsafe high levels or not turn on when the pressure drops to where it should restart the motor. If you are in doubt, have the regulator checked or replaced as overpressured tanks are very dangerous.

I have a central pneumatic compressor 21gal 2hp a couple years old the unit runs but will only pump up to 75psi and keeps running and does not build more pressure.It was building up to 110psi and then it...


Its the pressure regulator, if you discharge the air and can set the regulator to a lower psi, and it pumps

to that psi. you will have to replace that part, make sure to have make, model , serial# of compressor

so that the correct part can be fittted to you compressor. good luck!

I Have a 5.5.hp oilfree air compressor that builds air up to 45 lbs an stops building pressure and keeps run.will not shut off


Is you air regulator working? I suspect your reed valves in the head need replacing as they may not be holding pressure over the 45psi that you mentioned, and are allowing the air pressure to defeat them which allows the psi over 45 psi to bleed back into the air compressor cylinder.

Compressor shuts off before reaching max pressure


Yes,but if the max is 125 you don't want to increase it above 110 and set off the pressure relief valve.

Air Compressor will not build up over 25 PSI


your max pressure switch is faulty, and shutting off the power early. replace switch, check owners manual for location(should be near power wires)

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..
