Runs constantly but only gets to 45psi

Our twin stack compressor recently quit running properly. Now it will run constantly but only reach about 45psi. Has to be leaking from somewhere but not sure if it could be some kind of seal or what that may be easy to fix. Any ideas. All the hose connections and lines fron compressor to couplers seem good.

Good that you did the checks you did. A leak or open line can cause this.

What is more likely is your intake valve is leaking back out (is air being pulled in only?) or you may have a pump gasket internally that is allowing compressed air back into the chamber on the intake stroke.

Cheers,

Bill

I feel your pain
by: Noggler

I had the same thing happen to my Rigid twin stack. It was leaking out of the switch housing. They discontinued the original switch for my model, probably for that reason. I installed the replacement switch, and it worked well for a long time, until it overheated sitting in the sun. Now I want it to suffer eternal torment.

My Rigid twin stack will not start under load.

by Brian
(Wyevale)

I have a rigid twin stack that will no longer start under load. As soon as the little releif valve pops up the motor nearly dies.
If you turn it on and off a few times it will take off and work.
I did have this problem in the past when it was exremly cold or too much cord but now it is warm and plugged direcly into 20 amps and doing it. Motor maybe?
Thanks
Brian

Brian, could be a number of reasons why your Ridgic compressor will not start.

"little releif valve pops up the motor nearly dies." I am not quite sure what this means.

Turn the compressor off, dump all the air from the tank, and try to restart. Does it go? If so, make sure your unloader valve is working properly.

If it still will not start, go to Troubleshooting and follow the link to Will Not Start for more tips.

After checking all things noted, if still no start, please comment here and tell me what you found.

Cheers,

Bill

a ridgid double stack 5 gallon air compressor spits out the dip stick

by tom wilbur

My air compressor spits out the dip stick when the air pressure stats to build up. Why does it do this and how can I fix it?
_______________________________
Teach it some manners, Tom! :-)

The sump should have a vent hole somewhere to allow air in as the oil is consumed, which would allow air out then, too.

The vent hole likely has some sort of filter, and the filter and hole could be blocked.

Pressurized air getting into the sump could be symptomatic of piston seal wear, or an internal gasket / seal failure allowing pressurized air to bypass it into the sump area. Fixing the seal / gasket wear should resolve it.

Cheers,

Bill

ridgid ol5013al does not build ANY pressure?

ridgid compressor model ol5013al does not build ANY pressure.

II replaced pressure switch and installed a valve plate kit unit runs but no pressure is being built up. air is coming out of the tee fitting that goes directly to tank. could it be the check valve on the tank?

Anthony, it could be a bunch of things.

If you installed the valve plate kit upside down, that could do it.

I don't know what you mean by the T fitting that goes to the tank? A line normally runs from the pump head to the tank, and at the tank, it is common to have a T fitting with a line connected to the unloader valve. Is that line missing?
