There is a pressure regulator that is contained in the same housing as the on off switch. Take the housing cover off and see if there is a problem with the mechanics on the switch or the seal is bad.

SOURCE: Dewalt 4 gal air compressor will not build pressure in take.

The bleed valve is an unloader of sorts that allows the compressor to start with-out a load. It closes when the pressure in the airline reaches about 20-25lbs with good volume. If air volume is not sufficient, the valve will not close. To solve the problem lets do a few tests. A long cord will reduce power and reduce air volume. Try powering the compressor with-out extension cord. If bleed valve closes when you do not use a cord, the compressor is not getting enough voltage, use shorter cord of the 12 gauge quality and more hose to reach work. If valve still does not close, check for air leaks on all fittings including around pressure switch and drain valve with soapy water. Repair as necessary and retest. If no leaks were found, temporarily plug bleed valve port with screw/bolt and run compressor till set pressure cut-off while counting minuites/seconds. The compressor should fill and shut off within three minutes or so. If it takes an unusually long time to fill, then the reed valves /valve plate is worn and leaking pressure back into cylinger. Leaking valves will usually result in very hot discharge airline/air. Reinstall the bleed valve after test. Parts and partslist are available at www.toolpartsdirect.com . Good luck on the repair and email if you have other questions.

Probably the check valve has failed. It apparently is where the pipe goes into the tank from the compressor.

My dewalt 2 gal air compressor model D55141, when on hisses inside the pump housing. Sounds like a leek. Some pressure builds.


More than likely is leek. Must get to it to look at connections and air line to find out If slow probably would hear it. But loud you will find it. Tighten connections if it's there, other wise replace line

My D55141 heavy duty 2gal (7.6L) 150 psi max builds pressure up to around 150 releases pop off valve then keeps running, what causes this problem?


The pressure switch is either out of adjustment or has failed. The compressor should shut off at a much lower pressure than the safety valve (~100 psi)

D55152, left gage shows 40psi, right gage 100. Whats going on. how can i buy a manual? thanks


The right guage is the actual tank pressure. The left guage is the pressure for the air hose. If you turn the adjustment dial the air pressure guage on the left will go up or down. You should be able to go to the dewalt website and find an owners manual for this compressor. I personally own this compressor and it is a good one.

It only builds pressure to 70 psi.


there the pressure regulator between the 2 guages needs turned up. it may be a locking type if so pull out or push it in and turn it, if that doesnot work the regulator may need to be replaced.

Dewalt d55141 Builds only 45psi


Check the unloading valve. Accumulation of dirt might be preventing the valve to fully close, by-passing a portion of the compressed air.
