   Is there a full 15 amps available on the circuit it's on?

   Is the compressor warm or is this happening to a compressor sitting on the truck all night and then plugged in cold?  Oil or oiless?

   everybodys headed you in the right direction here,next would be the cap.

   i have one of those compressors and the reset button is hidden,i think up under the bottom of the motor,but it sounds like it is still getting juice. larry

   if a man speaks in the forest,and there's not a woman to hear him,is he still wrong?

   Been there, done it! This compressor can not be on an ext. cord, trips breaker.

   Trip's breaker when cold, oil must be warm. It's  plugged it do a 20amp.

   And it's in the basement now. I hit the reset button, turn it on the motor moves a fration of an inch and humms like its under labor. I flip the on/off back and forth, no go.

   I spin the fins/flywheel, thinking a dead spot, still no go.

    

   I am thinking the cap. , it sit on top of the motor, looks about what an old coil on the elect. system of a car.

   That is the cap. ?????

   I am curious to the problem hear as well. Mine was doing the same thing the other day.Mine was out in the cold but I warmed it up over night.It tripped it's breaker and I released pressure from the tank and it was working again.It seems like there was more to it than just being cold.

   Have you tried letting all the pressure out?
   If your view never changes you're following the wrong leader

   What I am getting from your posts is that it is very sensitive and easily trips the breaker.  My first guess would be to check the supply voltage.  If it is low, it may have been enough to start the compressor for you a number of times; however, this may have weakened it.

   My Emglo has been a bit tricky to start too.  I use only a 10 gauge extension cord to power it, unless it is plugged directly into an outlet.  It definitely does not like cold weather.

   Once it starts, it works fine.  It may also help to change the oil and use actual Emglo oil, which is very expensive.  I had to do my first oil change earlier than I would have expected; but it did help with the starting problem.

   The Emglo is a very finicky compressor, but, once started, it delivers.

   Good luck.

   I like my emglo. I use at least a 12 gauge chord if not directly plugged in. I shouldn't need an oil change but maybe. It has the original oil in it that came when I bought it. I have used it very litely as I have paslodes I use much of the time.An oil change as per a break in might be the answer for me.

   This is from the manual, which you can download from the DeWalt web site.

   The model is D55155.

   * The pump oil must be changed after the first 20 hours of oper -

   ation. Thereafter, every 200 hours or once a year, whichever comes

   first. In harsh environments, maintenance must be performed on an

   accelerated schedule. Always use DEWA LT synthetic oil.

   I'm not an expert but I have replace those Capacitors before on some of my dads larger electric motors. Once you have the cap off you'll be able to tell right away if its the capacitor it'll be all black by the terminals, the other thing it might possibly be is on my campbell hausfield one time if you pull the end of cap off the motor there is a small peice of plastic that is bolted to the center of the armature and it powers something in the motor and on mine there was a melted/loose wire. Thats all i got for ya. Good luck

   There is a "head pressure relief valve" in the copper piping that let's the compressor free wheel on start up .That's why you hear air leaking until the tank gets to 20 psi. Maybe it's stuck.
