WL373001SJ Campbell Hausfeld Air Compressor Pump / Motor Kit WL373001

WL373001SJ Campbell Hausfeld Air Compressor Pump / Motor Kit WL373001

I have a campbell hausfeld (6 hp 30 gallon) air compressor model wl611201aj that is about 14 years old.


When I turn it on the motor runs slowly then trips the breaker.

It doesn't matter if there is pressure or not in the tank. I have it plugged directly into a 120v 15 amp outlet. It has worked fine at the current location for some time. I recently switched outlets and the same result. If I use WL373001SJ Campbell Hausfeld Air Compressor Pump / Motor Kit replacement. Will this fix the issue.

Thank you.

Vincent, if this was my Campbell Hausfeld air compressor, from the symptoms you describe, I would be checking out the start capacitor.

That would be quite a bit lower cost fix than the kit you refer to.

If you prefer, however, I do believe that the kit would resolve your compressor problem.

Cheers,

Bill

VT623300AJ Tripping breaker
by: Bill

Your motor may have two capacitors, or one that does both jobs - start and run.

If either is failing the motor will run hot if it starts.

The motor itself may be suspect.

One check to try and determine what has failed is to check the capacitors to take them out of the equation. See that page on this site for help in so doing.

By disconnecting the motor from any load, you reduce the inrush necessary to start the motor, and it runs. Add the belt, you increase the load, and motor cannot start against it as, I suspect, the start capacitor cannot deliver the added power to get the motor going.

campbell hausfeld runs slowly then trips stops and trips breaker
by: long

but when i removed the belt, the motor runs without tripping the circuit breaker. would this still be a starter capacitor problem? if so, please explain. thanks.

CAPACITOR C103237300423

I am also looking for the same capacitor if anyone can tell me where I can get one. I called AEROVOX WITH NO SUCCESS

start capacitor
by: Anonymous

I believe I have identified the start capacitor in this compressor. I have checked it according to the checking capacitors page listed here and it is bad. as well as split and leaking.The numbers listed are Aerovox c103237300423. 233-280mfd. 220vac. 60hz. The 220vac is confusing me. The compressor has run from a 110v 20 amp circuit for years. Anyhow, can someone tell me the best place to locate the correct capacitor.
__________________
I suspect the rating indicates that it's good up to 220 VAC.

As to getting one, why not start with Aerovox themselves?

Follow up question

Can someone help me identify where the start capacitor is located on this model?

The two "humps" sitting on the motor are the capacitors. One is the start cap, the other is the run cap.

Motor tripping

I agree with Bill, start capacitor would be where to start on this one.

VT619503AJ makes a high-pitched squeeling sound - help!

by Vicki
(Missouri)

CH 6 hp 60 gallon, under 10 years old, Model VT619503AJ. Have two of them, bought at same time. One (I'll call "A") has been mostly idle in barn, used to pump tractor/atv tires occasionally.

The other ("B") has been used almost daily. We recently relocated A. It had had some 'dirt dauber' nests in it, which were cleaned out. It would run, but wouldn't fill the tank (husband said something about 'blow by'???). So, he took off the compressor from B, which had been running fine, and put it on there. B worked for about a week or so, but now it, too, won't work. It makes a high-pitched squeeling sound. HELP!!!!!

2hp 20gal Campbell Hausfeld after using motor won't kick back on

I have a 2hp 20gal Campbell Hausfeld, it builds air just fine but after I start using it the motor try's to crank back up but barely turns over a few times then nothing. I have to let the air out and wait a few min and start all over.
_________________
If you have to let the air out for the compressor to restart, it is typically and issue with your unloader valve not working, or your power supply.

If you are not using an extension cord or power bar, if the socket into which the compressor is plugged is working, if the amperage of the socket power is 20 amps (better than 15 for compressors) and if the compressor still doesn't start, and the unloader valve works, then it's likely the start capacitor.

See those pages on this site for more info.

I have a model # WL670100AJ 1.7HP 26 GALLON. WILL NOT BUILD MORE THAN 90PSI

Campbel Hausfeld WL604006AJ air comrpessor

The compressor will run and pump until it reaches 90 psi, it will not go beyond that. I have drained the tank, what can I do to fix this problem?

Well Tracy, you can look at the troubleshooting page about why air compressors run and do not build pressure.

Most of the things you will need to check are noted there.

Once that's done, if you wish to ask a specific question about what you found, add it as a comment here.

Cheers,

Bill
