SOURCE: Will not build up pressure

If this compressor is dry type with no oil needed, then it may have a worn cylinder and/or piston ring. With flashlight in hand, look under cylinder with piston in upper most position. If you see scratches most likely it needs cylinder / piston kit. Not to worry, not too expensive. If you compressor has a crankcase with oil, then you may have problems with valves in the head. Cracked or dirt under headvalves will prevent pressure from building. Finally there may be one or several leaks in the tubing, check leaks with soapy water. enjoy

SOURCE: compressor runs and runs but only builds 40lbs pressure

At the web address below you will find a parts list of your compressor. The most likely problem areas are the tube seal and the piston/cylinder. The tube seal seals the discharge tube to the head of the compressor. It will fail over time and cause the problem that you have. (only costs a few dollars) The other problem that you could have is a worn cylinder. Your compressor is oil free thus the piston ring is made of silicone vinyl and wears depending on conditions at the job site. Heavy dust/ dirt will shorten the life of the unit. With unit unpluged and covers removed, push the piston to top of stroke and examine upper portion of cylinder. If you see groves/scratches install cylinder kit. (cost around 39 dollars) In most cases I would replace both the seal and cyl kit. These parts are also available at your local dewalt service center or on line at dewalt.com. The folks at dewalt are very helpfull. Good luck with your repair and email if you have more questions.

SOURCE: craftsman 1 gallon direct drive oil filled wont build air pressure

It sounds like you may have a broken reed on the diaphragm plate. This is located at the block. Remove the cover, and look for a cast metal assembly with fins. It will be attached to the side.

SOURCE: low psi in reserve tank on a dewalt air compressure

This is a fairly common problem in small pancake compressors. I would start by making sure no air is escaping from the condensation drain valve on the bottom of the tank.

Next Pump it up as much as it will hold and turn it off. Listen for air leaks around the fitting on the bottom of the regulator that screws into the tank. These really need teflon tape and to be screwed in well.

Next check the regulator itself. These are rather inexpensive and don't last long when the compressor is used a lot. Also it doesn't take much of a bang when jostled around.

Is the regulator for tank pressure set correctly? Thump the glass covering the dial with your finger. Sometimes it sticks and you'll think it's set correctly when it isn't.

Lastly, check each connection for tightness with teflon tape. If all looks good, gamble about $20 on a new regulator. Odds are that's where the problem lies. This has happened to me a few times.

SOURCE: Was working normal suddenly will not build pressure

Maurader1 an apprentice has this problem solved and is spot on. All these gurus and wiz need to stick to the basic and common sense. The first place your pump will give out after use or abuse is the gasket. All this garbage about defective reeds and defective pressure switch is a lot of nonesense if you first don't rule out the most common problem the head gasket. I'm cheap and this thing has paid for itself 10 time over. You can get a gasket kit for $7, but I fabricated a gasket out of the back of my notebook and sprayed some gasket spray and been working like a charm ever since.

I have a Dewalt model D55166. It will not shut off when it reaches the maximum allowed air pressure. What could cause this?


If safety pressure release valve pops open then electric pressure switch is bad, however if compressure keeps running and never pops safety valve then most likely tubing / joint leaks or cylinder / ring worn out. Spray soapy water on all joints and drain valve , if no leaks suspect cylinder. Good luck

When you change from heat to air , it still blowes hot air like it is not switching to air conditing, the compressure is running and lines get cold, but no cold air. thanks


If the orifice filter is clogged, this will happen, a better check can

be done with an ac manifold gauge set, the low side reads the

evaporator pressure and the high side reads the discharge

pressure. I had the same problem while checking the ac on a

2000 gmc 1500 z71 4x4. other things that could cause this are

to much oil in the ac compressor or not enough freon in the

system. an overcharged system , the best way to check it is with

a gauge that way you can tell if you have the right amount of freon

and oil in the system. plus the gauge set will let you know the

extent of your problem. good luck!

Too hot little cold


Very possible your condenser is extreemly dirty and is turning off on a high pressure cutout. suggest you clean out condenser with compressed air. Brushing is not enough. also, check if condenser fan(at the compressor) is working.

Very hot compressure


Have frost on the compressor suction line moments after start, compressor unusually loud and labored, and overheating, means the system has been overcharged.
