VT619503AJ - Odd noise during pressure build up

by Rick Swander
(Kalamazoo MI)

My Campbell Hausfeld moldel#VT619503AJ 6HP 60Gal upright when running and building pressure sputters.


Almost sounds like an internal air leak or air moving past a seal.It builds pressure ok and works fine but this noise has me concerned there may be something starting to fail.I bought this comp.new about 11 years ago never had a problem with it.Any ideas? thanx rick in mi.

Rick, if it is taking a bit longer to fill than it used to, then I would suspect an internal gasket leak that lets go when the pressure reaches a certain level.

If so, then yes, eventually the gasket will let go completely, and you will have a compressor that runs and runs but does not build pressure.

Rebuild kit for VT619503AJ
by: Bill

Good luck when you do tear it down.

Yeah, if you Google VT619503AJ parts, you'll find sources.

Still doing it Bill but it works! Haven't broke it down yet. Maybe this year,spring. Are there rebuild kits for these compressors?

Compressor odd noise
by: Bill

Hey Rick. You say in your earlier post that your VT619503AJ is 11 years old. If you haven't done maintenance on it yet and it's still building air fine, aside from oil changes mind you, why mess with it?

I can't hear the noise but if it happens at the same pressure level each time, that may signify a gasket letting go a bit, like I said last time.

Monitor the time to fill from cut in to cut out. If that starts getting longer, then you've got a pump problem that needs to get sorted.

Bill my compressor still makes this noise,but it still builds pressure and works fine! Have not took it apart yet,it makes the weirdest noise while building pressure,almost like a hick up or air by passing.

Campbell Hausfeld air compressor will not start - blows breaker

by Ed Dietz
(Deptford, NJ)

CCH compressor won't start and blows breaker start cap has been replaced. Motor runs with belt removed.

Campbell Hausfeld DP461500AJ with Century AC Motor (A O Smith)B207-09 motor 4HP SPL 230V 3450 RPM. Start Caphas already been replaced.

I have C H (Iron Force DP4615) air compress with a Century start/Run capacitor motor. The start cap blew out and I replaced it with one from CH after several wrong ones but it now will not turn the pump before it pops the breaker. Spoke with both the motor company and CH but the problem has not been resolved. Could the run cap also be defective? Oh, by the way the motor runs when I remove the belt from the pump and just starting the motor only with no load. I can turn the pump by hand with little effort.

It is possible the start cap was/is defective Ed.

If there has been no change in the power supply to the compressor, and the start cap is frying, then I would suspect the motor itself as being the cause.

That the compressor motor starts without a load, and destroys the start cap when trying to start under load, and the pump sheave turns easily, makes me think that the motor is the issue.

campbell hausfield wont turn on

by jeff
(niles, oh)

I have a 2hp, 8gal 125psi campbell hausfield compressor. I have used it many times without fail, then one day it wouldnt shut off.

It felt like the shut off switch was broken, cause it was wasnt catching when I turned it, then it caught and shut off. I used it several more times without any problems then it did it again but now it wont turn on. I took unit apart and switch feels like its connected and working but nothing? any ideas?
_________________
Jeff, when you say your Campbell Hausfeld air compressor would not shut off, are you saying that the compressor would run until the PRV let go, or are you saying that the air compressor cycles properly, shutting off at the cut out pressure and cutting in when it is supposed to, but if it is running when you shut it down, the ON/OFF switch does not cut the power?

To test, use a multimeter and probe the power line on the downstream side of the ON/OFF switch with the switch shut off. If you have power flowing to the pressure switch from the ON/OFF switch with the switch turned off, then your ON/OFF switch is probably pooched.

If I understand the compressor problem wrong, please add a comment here to correct my understanding.

CH compressor will not cycle back on

by Eddie Walker
(Dickinson, Texas, USA)

My CH compressor will build pressure and will SOMETIMES not cycle back on after it bleeds down. I turn it off or unplug it and let it sit for a couple of minutes and it will pump back up and sometimes cycles and sometimes it wont until I unplug and restart.
_________________
OK Eddie, what's happening when the pressure in the tank drops to the cut in level.

I know you say it won't start, but when the pressure in the tank drops to cut in, the pressure switch should trip on, and power should flow to the motor to start it up and get the pump pushing air back into the tank.

When the pressure in the tank falls - as you are using air - to the cut in pressure level, does the pressure switch trip?

You need to answer as a comment here, as if you start a new thread I cannot connect the two.

Cheers,

Bill
