919.165230 Craftsman compressor won't stay on.

Hi, I recently bought a Craftsman air compressor model 919.165230 5.5hp 25 gal and plugged her in only to see that she shorts a 20 amp breaker with nothing else plugged in.


She will start, but struggles the entire time builds air very slowly then will trip the break after about 30 seconds of running.

Trying to restart it is even more of a problem, it just won't go over after that initial trip.

Which screw? part 62?

Got it to stay on

I loosened the screw at the top of the piston because when I spun the compressor by hand I felt it was to tight and it's actually staying on now

I was looking for specs on this, and according to an auction site, this is single phase, 60HZ, 120V.

So the 5.5 HP is inflated b.s.

Still, if it has a 120V 20A plug on it, it should run - so this goes back to being a capacitor or maybe pressure switch problem (burnt contacts).

Then I found it has a conventional 15A plug, so even more b.s.

What voltage?
by: Bill

If you check you'll find that a 240 volt 5.5 HP motor requires just over 20 amps to run right.

Inrush may require substantially higher amperages, and if your compressor is wired into a 20 amp breaker, that's likely the problem.

If it's on 220 it should be at least a 30 A breaker.

919.165230 start up problems
by: Bill

Yup, sure could. Don't know why a new compressor would have start and/or run capacitor problems, but that's a logical check too.

Yeah, it's close to the breaker and wired correctly I also can't take it back as this is a discontinued model & out of warranty. Would capacitors have this much influence on it to do these issues?

919.165230 won't run
by: Bill

I'm no electrician, but what I'm thinking is that your wire size may be too small, and a 20 amp breaker may also be too small based on the distance from the breaker.

A quick check suggests you should be using #8 gauge wire.

If you Google what size breaker for 5.5 HP motor you find that it is the wire size or breaker amperage.

If your Craftsman is wired within the code specs, then add a comment here and we'll hope the community can help.

If it's a new compressor, and wired correctly, maybe it's time to take it back under warranty?
