My Kobalt Air Compressor Model 215914 won't compress air

Bill'


My Kobalt air compressor, Model 215914(VLK1382209), 22 gallon Tank Air Compressor, Won't compress air.

When I turn it on I don't hear the normal air compressing motor sound.

I hear a loud constant hissing sound, like air is blowing out of the top where the motor is.

The air is not getting compressed. It runs constantly because it never gets to its pressure shut off level. Pressure is not building up at all. Any thoughts?

Thank You

Hi Bill...

A bunch of tips in the troubleshooting section on the site map about just this issue.

The hissing sound suggests to me that the intake valve might be pooched, and it's simply pulling air in and then blowing it right back out again as the piston cycles.

You should be able to feel that if you can find the intake filter on the compressor somewhere under that shroud.

Cheers,

Bill

What Bill has to say is good to go,but I also would check the head gaskets themselves to see if one is blown.If you can take a regular piece of paper and move it around each head/heads and see if it is blowing around the head and gaskets checking for a leak.You may have to block some of the air from the flywheel to do so with a large piece of cardboard between the flywheel and and the paper.

My compressor will run and not build pressure beyond 40-50psi and will not shut off.

Do the checks, then post as a comment here with what you found, if you would.
