over heating Campbell Hausfeld air compressor

by Fred Parisek
(Michigan)

When running my compressor for an extended period of time. Say shooting paint or using air tools. After a period of time of running the compressor shuts down. I have to wait for about 30 min before it allows me to restart it. Do I need to replace something inside the motor and or a regulator?

What you need to do is check and see if your air compressor is rated for continuous duty cycle. If not, then you are likely running to the point of overheating and it needs to cool down.

With the absence of info on model, HP, tank size etc. to corroborate this, my gut feel is that your air compressor is too small for the work you want it to do.

Cheers,

Bill

Right on the money with my Campell Hausfield 200psi 1.3amp compressor. The thermal diode on the electric motor was shutting things off before it reached 200psi. Followed Blackfoots comments, placing a thermal spacer between diode and copper wirings, zip tying back tightly into place, and she goes right up to 200psi again. Just hope it does its job when things do get really hot from running... should still trip if it gets thermally overloaded... close enough to the coils....

OK...
1. If your compressor is shutting down before reaching max pressure, and you can unplug it with the switch off for 5 minutes, and then plug it back in and turn it on and it will charge up a bit more. This is not from the PRESSURE switch.

There is a temperature sensor on the electric motor that is breaking contact prematurely. It is located underneath the plastic shroud on the right hand side of the motor.

You will see two insulated wires come together side by side into a flat tab with insulating plastic on it. Replace it or do as I have done and cut the plastic strap and slip off the other holding wires and slide one insulating wire between it and the copper coils. It will still work but will run a bit longer before shutting off.

2.If you're getting air to the direct line you added to the pump but not the tank; it is the valve.

Take the top plastic shroud off. Look for the air line coming directly out of the pump; it leads to a brass fitting with a shallow hex head cap with a rubber O-ring.

Take off that cap; you will see a spring and a rubber cup that pushes down AGAINST the air being pumped.

The compressed air should force that rubber cup / valve open during compression and the spring close it when on the down stroke. It may be stuck. Try lubing it with a bit of compressor or air tool oil. And don't forget to add a little to the O-ring on the brass cap before putting it back on.

Campbell Hausfeld compressor pumps air but not to tank

by Carles
(Galax Va)

I have a Campbell 26 gal compressor and it has the quick blow outlet, when running the quick outlet has air but none to the tank .
_____________
I'm having a bit of a problem understanding what you mean by a quick blow outlet?

Are you saying that you have air blowing out of the compressor all the time when it's running?

Please provide more details as a comment here.

Cheers,

Bill

Airflow

No,on the bottom I have permanent air hose with blow gur for quick air and compressor is pumping and I have air to this hose but none going into tank. The hose is connected to a fitting that supplied this hose as well as tank. The hose is getting air but not the tank.

Still having a hard time visualizing it.

However, if the feed for the air hose is part of the feed for the tank, and the compressed air gets to the hose but none goes into the tank, where the line enters the tank is normally a check valve. If that's somehow sealed up then air would not go into the tank.

If you are disassembling this to check, make sure the compressor is off and you drain all the air from the tank first.

complaint about Campbell Hausfeld pressure switch

by Larry Nopen
(Arizona)

I have a 3 hp, 60 gal. compressor. It is 4 and a half years old, it has went threw at least 1 pressure switch 1 year, at the cost of 49.00 a pop.

called the 800 help line, changed the check valve, same problem.

I can click the pressure switch back and forth a few times and it will try to start.

All electrical wires are tight. My 5hp 80 gal never had this problem, and there was no phony on / off switch on it. Do you have the part # for that switch. Thanks Larry Nopen

Well Larry, as I have often said, in the drive to offer DIY compressor users ever lower cost compressors, somethings go to give, and that's the quality.

I don't have the model number of your Central Pneumatic air compressor, so I cannot try to find the specs on your pressure switch.

Click the link in the nav bar about compressors and parts here, and have a look at the selection of pressure switches.

You don't need an OEM switch for your compressor, just one that fits, has about the same pressure range, similar cut in and cut out, has the same voltage range and the same unloader connection.

CH pressure switch
by: Doug in s.d.ca

While yo're at it, consider checking your capacitors, and maybe try to get a higher amp rating on the new one.

Sounds like something is causing the contacts to burn.
