SOURCE: WILL NOT BUILD PRESSURE

Many craftsman compressor are built by champbell hausfeld using a dry type of cylinder and piston (no oil, no crankcase). If dry type, check for worn cylinder and piston ring. Pieces of the vinyl ring can jamb between the reed valves in the head causing air to escape from the intake. If your compressor has a crankcase and oil, check for broken reed valves in head. Spray soap solution on hoses, checkvalve, drainvalve, and fittings to check for leaks. Most likely problem is reed valves broken or open. Parts are available from sears or match parts to chpower.com. enjoy

SOURCE: coleman compressor no build up of pressure

your correct either the valves are worn or maybe just need cleaning as for the gaskets,idont know what part of the world your in but check out coleman on the internet or failing that ,i have maid these from gasket material suuplied from my local bearing supplier

SOURCE: coleman compressor no build up of pressure

Parts for coleman are available at www.mastertoolrepair.com your compressor is listed as L0502710. If however you like to tinker, you can make a pretty good reed valve out of aluminum can material or other (any ideas?). It is fairly easy to cut, does not last as long as factory stainless steel, but for short term, why not? Good Luck

SOURCE: air compressor not filling tank

Most compressors with the problem that you are having suffer from leaking valves. As in a gasoline engine, leaking valves will lower efficiency. Valves in a compressor are in the form of reeds that seal against valve plate. Leaking reed valves or gaskets will increase the discharge air temperture. Inspect these parts with a magnifying lense. Look for evidense of wear or leaks. Also look for signs of air leaking from one cylinder to the other thru gaskets. Replace valve plate as necessary. Simple test, as your compressor is filling, check the intake for strong suction; as it neers the 92 psi mark suction will probably deminish if you have leaking valves. If suction remains strong at 92psi then you have a leak at the discharge side. Check with soapy water on all parts. Good luck

SOURCE: air compressor fills, but slows down as the pressure builds

sounds like you need a new check valve which should be somewhere between the compressor outlet piping,tubing,etc and the tank which prevents the air in tank to back feed to the compressor which would cause hard starting and could damage the motor easy way to check is when you shut off the compressor with some air in the tank if the check valve is bad it would continue to bleed air out out the unloader valve .the unloader valve on your unit is most likely part of the pressure switch when the unit shuts of it should only bleed down the pressure in the pump so it would make it easy to start when needed hope i didn't confuse you

My ingersoll rand compressor won't get up to set pressure


Hi bryon


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.
Please take time to rate me

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.

Alton 1/3 hp 2 gallon air compressor, building no pressure and sounds funny


Is your compressor a piston compressor? It may be that the valves in the head are shot?
Remove the Air Filter and quickly place your hand over the air intake hole, if you feel it **** AND blow, then theres your problem (It should only ****) these can be replaced.

I have a husky scout 1.5 gallon air compressor. It only builds pressure to about 38 psi. It doesn't build up any more pressure.


You have either warped or broken reed valves on the valve plate or a broken piston ring and/or a damaged cylinder. Any of these will allow a small amount of air compression but as the tank gets pressure in it, it gets harder to push more air into it. If the reed valves or piston to cylinder seal is compromised more and more air will leak past the bad reed or the piston as the pressure goes up in the tank. You'll have to disassemble the air pump to find out what's damaged and needs replacing.

First take off the head on the air pump and check the reed valves on the valve plate. If they got hot and warped or cracked they'll work to a point then no more pressure can be built up. Next check the pistion ring and cylinder wall. If either is damaged you'll only get so much pressure build-up then it will leak past the piston.

Oil free pumps do tend to blow the piston ring (not too expensive) available at searsparts.com. Remove covers to pump and manually turn crank until piston is at top and look at the condition of the cylinder neer top, If it looks scratched, order cylinder kit with piston ring. If it looks good and shiney, could be the valve plate in the head. There are reed valves that tend to break. Run pump however with covers removed and check with soapy water for air leaks and repair as needed (air leaks under the cover will prevent unit from filling). Good luck

Compressor runs but wont build pressure


You are probably leaking past worn rings and/or through dirty or broken reed valves. You don't mention a make or manufacturer. Contact them for repair parts.

Compressor 25 psi thats it


I assume it keeps pumping, but doesn't build any more pressure. That is probably bad valves or rings. If your unit has a crankcase breather, and it is puffing alot of air, look for rings. Otherwise valves.

I have a 25 gal compressor and it will not build pressure. The motor runs but will not build pressure. The compressor is about 25 years old


You got a good life time with this. The compressor has seals or "rings" which wear out over time. Replace them and your compressor will love you. It won't hurt to check all the lubrication points. This procedure is easy for even a novice but may require a special tool. Go to your local small engine repair shop and ask. They will be glad to help you.
