Chicago forge horizontal air compressor will not build

Chris:
Sounds to me like you have an air leak somewhere. When the compressor motor runs for too long a time, it's 'gonna get hot! Disconnect the fittings one at a time and use Teflon tape at each air connection. Check for leaks using a soap and water solution at each fitting.

Hi dennis


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 suck 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.

Bad check valve. But I would check the regulator, by turning it down to about 10 PSI and running it and see if it builds again, if that works then it is the check valve. But from what you are saying I would replace the check valve anyways.

send me a photo of your pressure switch with the cover off and I will see if I can help you!

Check to see if air is leaking past 'pressure relief' valve. It's probably leaking and that's where all the air is going.

they hold 150psi tops but i would set it to 100psi as this extends the compressor life

Check the oil first and the make sure the discharge tube is clear.

hi your problem sounds tp be associated with your nonreturn valve this is not sealing ,allowing pressure to flow back to your pump from your reciever/tank ,this is a"service part"and do require replacement periodically
hope this is of help ian

Hello,check to see if it cuts off at the same psi each time.If so,youneed to adjust the pressure switch to the tank to the max & adjust the pressure to the tool you want to run with the pressure out kob.Hope this helps
