919.167342 trips breaker on start

When I start the compressor it bogs down, then trips the breaker. If I toggle between start and stop, it will kick on, but then when pressure gets low and it tries to kick on, it trips the breaker. It sounds like start capacitor but here is the thing... when I take the shroud cover off, I see neither a start capacitor nor a run capacitor on top of the pump assembly or anywhere else I can see. The diagram in the manual does not show one, either, but lists a start capacitor with diagram number 76A, but there is no 76A on the diagram (part 76 is the pump assembly). On videos that I have found on youtube of similar craftsman compressors, the start and run capacitors appear to be located on top of the pump assembly. I am at a loss. Thanks!

So Buster was right - thanks for that info.

Would you post the specs on the motor (model and mfr, mainly) along with the cap value(s)? Might help the next guy.

Found the caps
by: Anonymous

OK-- This was my question that I posted and I found the capacitor. The year model I have does not have the caps located on top of the pump assembly. That was what was baffling me. However, I removed the pump assembly and took the back off. They are actually located INSIDE the pump assembly on this model. The pump assembly has a slightly oversized housing just big enough to fit the caps inside.

919.167342 motor cap
by: Doug in s.d.ca

Right - the motor is unavailable, and the cap is not listed because there were multiple suppliers of the motor which were mechanically the same but different internally.

So far, it looks like they all have an internal cap located under a sausage-like cover on the motor.

The I.D. plate is right next to it.

Please look under the cover - if we're lucky, the cap will be marked with the value. Look for that.

Let us know if you have trouble finding it. For that matter, if you do find it, let us know so others can benefit from your efforts.

Thanks and good luck.

Motor capacitor
by: Buster

Hey guys, just a thought! I don't know anything about this particular motor, I have seen motor caps mounted inside the end bell of the motor, completely out of sight!! I don't know if you have had the end bell cover off or not , might be worth a look at!!
Hope this helps!!

calls out different cap kits, based on the exact motor OEM. if you look at the picture of part # 76, the motor, you notice the tubular bulge on the top of the motor. i am pretty sure that is where the caps are located.

I, too, have searched for information on the capacitors for this motor with no luck.

The specs say it has a motor providing 2HP running, and that size of motor typically has a start, a run, or a start/run cap.

In terms of things to check, please see:


Anyone else have any info about this compressor?
