Campbell Hausfeld wl611200aj - am I ripped off?

I bought a campbell hausfeld wl611200aj - just bought it - am I ripped off


The motor kicks on builds air to 60 psi quickly then keeps running but won't build anymore pressure.

I hope I didn't get ripped off. I noticed after I got it home and hoping its an easy fix.

Joshua, there are a number of common reasons why an air compressor will run, build air pressure to a level, and then stop building pressure while the air compressor keeps running.

Valve and gasket failures seem to be the most frequent reason. See the sitemap page, look under troubleshooting, and see the pages about why air compressors run and do not build pressure for some tips.

if you purchased this Campbell Hausfeld air compressor new, then take it back and get a new one.

If you bought it used, and it was implied that the compressor was OK, then I think you have been taken, my friend. I am sorry about that.

Good luck,

Bill

Campbell Hausfeld 5HP air compressor won't start?

by Randy
(Brenda, AZ)

I have a 13 gal. 5 hp compressor that will not start.

I've made continuity checks across the wiring and pressure switch and it is all good.

I plug the unit into a properly grounded 20 amp circuit directly but to no avail.

I visually checked the contacts on the pressure switch and they look good.

Assuming that the wiring and armature are good, what else will prevent this unit from starting.

I have not pulled the head off or anything else because I believe the problem is electrical or air related as the motor ran fine the last time it started. Will a bad check valve prevent the unit from starting?

Randy, when you say you have checked the wiring and it is all good, did you actually use a meter to see if power is flowing through the pressure switch to the motor circuit.

If the tank is empty, the pressure switch should have tripped to allow current to flow to the motor. Therefore, you should be seeing 220 in and out of the pressure switch. If that is not happening, then it is the switch that is the culprit, I would say.

If power is going to the motor, then the next suspect would be the start capacitor. See the page on how to check that.

A non-working tank check valve should not be an issue in preventing the air compressor from starting.

Let us know, will you.

5.5 campbell hausfeld air compressor won't shut off

by michael

I replaced the pressure switch on my 5.5 campbell hausfeld air compressor "oilless" type and it will not shut off .I shut it off myself when it reaches 140psi

If the air compressor fills the tank in about the same time frame that it did before, and the pressure in the tank passes the normal cut out pressure setting of the switch, then it is still quite likely that your pressure switch itself is the problem. Wiring issue?

That, or the cut out setting on the new switch is substantially higher than the old, and you are shutting off the compressor before the tank pressure reaches the cut out setting of that switch.

campbell Hausfeld 30 gal 6.25hp model WL611201AJ wont restart above 40 psi

by Gary M.
(Hartland, WI USA)

My Campbell Haufeld 30 gal 6.25hp model WL611201AJ runs when tank is empty but wont restart when at restart pressure.

Motor makes a couple of slow turns then kicks out breaker.

Discovered this happens when pressure is above 40 psi. I have already replace the unloader and one of the capacitors (grey one) which did not work. Any idea's???

Good that you replaced the unloader valve, if it was not working.

If you are not using an extension cord or power bar, and if the power supply to the compressor is from a circuit that does not have other things pulling power when your air compressor is trying to start, and the capacitor you changed was the start capacitor and not the run cap, then I would suspect the motor itself is failing.
