    An air compressor is identical to a gas engine except no sparkplug and no gas injected into the cylinder. If there is no pressure build up it can be the intake valve is broken, the exhaust valve is broken or a check valve not working properly. The valves are usually reeds valves that require you pull the head. Is there no pressure build up at all?

You said it "just stopped". Was this a sudden problem? Does "stopped" mean the pump or motor?Did the motor continue to run during this incident?

Depending on the type of compressor pump, age and hours of service it may simply be worn out. It could be worn rings and cylinder/cylinders, leaking head/manifold gasket or blow back through the valves depending on the type of valves.

But if it's an issue of wear older is definitely not a bad thing when it comes to compressors. Granted there are exceptions to every rule. These exceptions would include compressors made by companies out of business or models that no longer have spare parts made for them.

In order to help you more you are going to have to include a little more info.
Make and model # of the compressor. Did it stop completely, (pump and motor), or was it just the pump would not build any more pressure?
Please respond to me with as much info as you can and I'll do my best to help

We relocated our Sullair 3700 about 30m from air receiver, due to excess dust. Now the compressor never stops running, trips on high pressure yet the receiver is not achieving the pressure required


would say dust has done something to do with it
before you had time to move it

will need the compressor serviced

first ..in simple words
to replace the compressor pressure shut off /turn on valve
that should fix the pressure trip build up limit problem

and maybe a partial strip down to clean out the casing
if dust build up is noted

Cf2600 won't build pure pressure. Could air intake be stopped up. Had dirt dobber stop up on older compressor. Where is air intake. Can't locate.


No there is not a filter. Since the pump is enclosed in the plastic covers there would not be a way to service it. Now if it is not building any pressure then it could be a few things. First would be the drive belt. (item 125) If it breaks then it won't pump at all. Also if the air hose that exits the pump (item 122) gets a hole in it then it won't fill the tank. A worn head valve plate (item 106), blown gasket (item 105), or a worn piston and sleeve (items 109 and 112-2) can also cause this. If the check valve into the tank (item 16) gets stuck open it too will limit how much the compressor will pump BUT usually it will build up some pressure then just keep running without building any higher pressure into the tank.

Here is a parts diagram so you can see where the belt and other parts are located plus it contains all of the part numbers.

Hi have a cosmo air compressor that will only build up 25 lbs of pressure instead of 12olbs?


If the compressor is older or had a lot of use the rings might be worn. Try a compression test on the cylinder to see if there is bypass in the rings.Try this onlt if it keeps running and doesn't build pressure. If it builds up and stops at 25 lbs. the problem is different it would be in the pressure switch. You can then try to increase the the shut off pressure in the switch by turning up the adjustment screw. if this doesn't work I would then change the presure switch for a new one.

Compressor tamk pressure


That small piece of rubber came from the compressor pump, more than likely you have a broken valve or blown head gasket in the pump, that is why it will not build pressure.

I have a Campbell Hausfield wheelbarrow type compressor model #vt617206aj that will not stop making air, just builds and builds until emergency relief vave opens. please help


It sounds to me that you have a defective regulator valve assembly.

This is not a trivial problem. It should be repaired and NOT used until it is repaired.

The emergency relief valve is there for a reason --- to prevent an explosion of the pressure vessel if the regulator does not shut it off.

This is not a do-it-yourself type of repair. A machine shop, or even a welding shop could probably do this repair for you.

If the compressor is an older one or a low value compressor, deep six it and get a new one.

EC-12 runs but only builds to 35 psi and continues to run


It looks like there might be a knob which sets the max air pressure coming from the compressor. If there is one, this may have been turned down.

There are usually 3 pressure settings on an electric compressor. Compressor max, pressure switch cut on, and pressure switch cut off.

Compressor runs hot and won't build pressure


THE COPPER LINE IS SUPPOSED TO GET HOT, SCALDING HOT ACTUALLY. THE MOST COMMON REASON FOR COMPRESSORS NOT BUILDING PRESSURE IS CLOGGED AIR FILTER OR THE VALVES IN THE HEAD ARE BROKEN OR NOT OPENING AND CLOSING CORRECTLY. YOU MAY POSSIBLY HAVE A BAD AIR LEAK DOWNSTREAM BUT YOU CAN CLOSE THE DISCHARGE VALVE ON THE TANK TO ELIMINATE THAT PROBLEM. HOPE THIS HELPS OR GET YOU STARTED.
