SOURCE: portable air compressor wont turn on

1st check for power at the pressure switch. Take the cover of the switch and make sure you have line voltage at the terminals from the wall outlet.
if no voltage>replace cord or plug end with proper gauge wire.
If voltage, then, while you have the cover off of the switch **Make sure it is not plugged in** and operate the on off switch and visually check the operation of the switch. You should see some flat copper terminals that, when the switch is turned on, kinda rotate and drop onto some other copper terminals. The connection is kinda like points on a old car ignition, little pads on each copper thingie contact each other. I have seen these little pads become pitted and burnt from arcing. Try to clean these with a small file or pick if they are corroded. Get some electrical contact cleaner and clean the switch completely, *it is not only electrical, but is also mechanical*. Switches will intermittantly work, replace the whole pressure switch if there is heavy wear, charring or working intermittantly.
If this is all good, check the wires coming out of the switch for power to the motor, replace if necessary. If this is ok..
You probably have a bad motor. I have not had much success in revitalizing motors, its usually better to just replace it.

SOURCE: dewalt D55155 air compressor regulator installation

The d55155 unit suffers from regulator problems due to weakness in the design of the manifold. The manifold parts are very light duty metal and will break during installation if not carefull. If you can return the parts to dewalt it may be more efficient to to use a generic pressure regulator from www.grainger.com for about 20 bucks and mount using a couple of 1/4" tees directly off the pressure switch. Remove the hose from the pressure switch that feeds air to the manafold . Install parts so that the quick disconnects, guages and new regulator are accessable from the side. It will not be pretty but problem will be solved for long term. We repair other brands that come with control panels using the same method. Pressure regulators built into a manafold will fail. For demanding customers we have recreated the manafold using 1/4 pipe fittings and refit the gauges and grainger regulator into panel.(lots of work) But leave the safety unloader at the pressure switch. If all you need is a good functioning compressor same time and money and mount to side. Good Luck and email if you have questions or other issues with your dewalt.

SOURCE: Air Compressor

Dewalt recommends synthetic oil in their compressors. The dewlat part # 5130427-00 quart, and 5130702-00 for a 4oz size. Available at www.dewalt.com or their service center. I have been using the Lowes brand of synthetic compressor oil. Kobalt oil sells for about $7 and works great. If you do not use your compressor all day like I do, you can use the standard grade of Kobalt compressor oil that sells for around $3. Synthetic oil is for extreme conditions. Good Luck!

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.

Dewalt d55155 compressor runs to 60 lbs then acts like not enough power and shuts down


Looks like it's an oiled style compressor. Is it getting pretty hot by the time it hits 60psi? Might be low on oil, or the oil has been contaminated with water from condensation. If that's the case then what is happening is the compressor is causing too much resistance for the motor to turn it because of the excess friction. This is could be what is causing it to shut down prematurely.

Dewalt compressor not filling with air drained tank closed valve


Some dewalt air compressors with single cylinder are known to develop trouble with reed valves and /or failed gaskets in head. Parts lists and parts are available at WWW.toolpartsdirect.com Simple test is to remove air filter and check for suction at intake. Bad reeds will tend to blow air out intake as pressure increases. Failed gaskets in head will cause very high temp at discharge hose. Parts are not too expensive. Enjoy

Dewalt compressor not filling with air


if you do not have any air leaks and it is a oil less compressor than it is most likely the piston seal is wore out. if it is an oil compressor that it is likely a flapper valve
