Kobalt 80 gallon upright compressor AIR LOCKED?

by John
(Clarksville, TN. USA)

Have had my 80 gallon Kobalt for 3 years.


The air doesn't flow from it. Really puzzling!

Has two front built in ports regulated.

Has one side port unregulated.

The side port I use with a valve and goes to the PVC air line which goes to my cnc plasma cutter. The cnc is not getting enough air and can view a guage next to cnc showing the air has dropped down to about 40 lbs. The tank still reading between 120 and 145 lbs.

I disconnect from the side port after shutting off the valve and connect to one of the 2 regulated ports. Same problem! Two gauages built in. One shows that there is 140 lbs in tank. The regulated guage which is set to deliver 120 lbs shows only 45 lbs of pressure and very slowly while watching will climb back up to the pressure of the regulated set on guage.

I suspected maybe the built in guage would be bad but to have the same problem on the side port which is unregulated. I ran a straight hose from the UNregulated port to the cnc and have the same probem.

Can still watch the guage on the front of the compressor climb from 40 or 45 PSi back up to 120 psi slowly while the other gage shows 140 psi in tank.

At a real loss of what to do and can not run my cnc plasma cutter. Of course Kobalt has no tech support. It has been a great compressor and has run faultless for 2 of 3 years.

Keep filters changed and keep water drained out daily.

Just can't seem to get the air out of the tank. Any ideas on this one?

John, are you certain that the unregulated port has air directly ported from the tank, and is not, in any manner shape or form, flowing through the regulator?

Your symptoms suggest to me that you have a failing regulator, but I, too, cannot figure out how air plumbed directly from the tank to a discharge line can be blocked.

It were me, I'd start by dumping the air with the compressor off, removing the entire regulator assembly, and install a discharge coupler directly connected to the tank pipe. If air flows out of that coupler satisfactorily, then it's the regulator that is the problem.

Cheers,

Bill

Charles, I don't fix electric motors, yet I would suspect that to find replacement brushes for a motor, you would need to know the HP, the make, the model (if one) and source replacement parts from an electric motor rebuild house.

And, you can ask folks that fix electric motors to help, and you've now done that with this posting.

compressor wont start

I have a 26 gallon Kolbalt compressor. I turn the switch on and it does nothing. Please help! Thank you

Johnny, is the power supply good. Is the tank empty of air? Is power, since there is no air in the tank and it should have switched on, flowing past the pressure switch to the motor circuit?

See the Troubleshooting section on the site map page for links to pages with tips and solutions about why air compressors won't start.

Cheers,

Bill
