Campbell Hausfeld won't build enough pressure to cut off

When I manually cut the pump off it holds the pressure and has no obvious leaks.

_______________
Not an unusal problem and one that is covered fully under the troubleshooting section. Look for the page that refers to compressors that will not shut off, or will not build pressure for some tips.

If you have a specific question, please add a comment here and include the model number of your air compressor.

Campbell Hausfeld HG300000 compressor fails to refill

Campbell Hausfeld HG300000 compressor

Campbell Hausfeld HG300000 compressor

Hi folks, I have a Campbell Hausfeld HG300000.

This is a 200psi compressor that refills at 150psi.

When the tank is empty, it fills to 200psi just fine. When it hits 150 and attempts to refill, the compressor attempts to turn on but is unable to start.

You can hear the motor softly hum. After about 6 seconds it trips the panel breaker (15A).

I am not having any issues with leaking air, and I don't think the tank check valve is leaking. Any ideas?

**Please don't say I need to rebuild the head.(wishful thinking)**
Thanks

If your unloader valve is working properly, then you likely need to check the start capacitor, Thomas.

That is assuming that all other conditions on the compressor haven't changed, and it was working well with the power supply setup you are using now.

Cheers,

Campbell Hausfeld HJ300100 compressor will not build any pressure

by Mike
(Parker, CO)

I have an HJ300100 Campbell Hausfeld air compressor, 3 yrs. old, used primarily on weekends to help w/ remodeling.

One day while using it, the machine stopped building pressure while still running just fine.

I have replaced the piston and cylinder wall (Kit assembly)and new pressure switch but still no tank or output pressure.

I have let the motor run for ten minutes, but again no tank pressure.

The discharge hose from the motor to the tank has plenty of output and the small hose to the pressure switch also has air going through it.

I have drained the tank also.

Pulling the air release valve on the manifold also does not confirm any tank pressure.
__________________
Mike, that there is air flowing into the tank when you pull the line says that as long as there is little or no back pressure then the pump sends air that way.

I suspect that as soon as there is back pressure from the tank, that the gasket between the high and low pressure sides of the pump lets go, and air cycles back and forth, or, your intake or pressure valves have a problem.

Campbell Hausfeld WL6700 air tank won't fill with air?

by J Smith
(Huntington, WV)

I have a Campbell Hausfeld WL6700 30 gallon air compressor. It's approx. 3 years old and used every other month to simply pump up a tire. Very light use.

It has a 30 gallon tank for operating attachments if you desire or need volume and has an "instant air hose" to quickly pump up tires so you don't have to wait on the tank to fill.

This is primarily what I use and I can't remember the last time I ran it long enough to fill the tank.

However, I went to try and run an impact wrench on it the other day and noticed the tank no longer pumps up?? The motor runs fine and the "instant air hose" works great so I know the pump is operating properly.

However their must be some type of valve or switch that's preventing the tank from filling up. Any ideas?

No Fill
by: J Smith

The motor runs fine and pressure through the RIT is good. The gauge on the side shows no pressure at all. The drain valve has been drained and is closed and I've checked the quick release valve. I can't hear any leaks. The motor runs and after about 20 seconds it starts changing pitch as if the tank was completely full. Kind of like when you cover the hose of a shop vac, the motor pitch changes slightly but the pump continues to run. But, since it's not filling up, I don't let it run more than a minute or two. Using the RIT to blow out air cleaners etc works fine but the 30 gallon tank and gauge show to pressure at all. When I pull the quick release valve or open the drain valve very little air comes out--basically only whats in the air line itself.

I tried to find an image of this compressor so I could see how it's plumbed. I could not. Once again, a photo is worth many words. Seeing the plumbing would certainly have helped.

Check the flow path of the air from the pump to the tank. Does the fast fill air line come off the line before the air line from the pump head enters the tank?

If so, then it is possible that it is the tank check valve that is seized shut, preventing air from entering the tank.

Regardless, open the tank drain valve and with the power off, disassemble the line where it enters the tank and test the flow through the check valve. You blow through the various openings to see where the air flows.

If you cannot emulate air passing from the pump line into the tank through the tank check valve, it probably wouldn't hurt to replace it as the next step in trying to solve your compressor problem.

Here is where you can get one if you decide to go that route.

OK, so you turn it on, you get pressure from the RIT hose, but not in the tank? (gage on the side)

Does the motor continue to run, or stop?

If it's continuing to run, then my guess would be the drain valve by the tank gage is open.

If that's not it, come back after checking the no-fill page here.
