Default Air Compressor done?

My little 8 gal BCP air compressor that I keep in the basement wouldn't go when plugged in. Nothing. Question is ...... what could it be and is it worth fixing. It is 15 years old or better. I'm thinking control valve. Is it worth fixing or just buying another small one. All I use it for is blowing dust off the CNC bed and benches, and a little finish nailing. A new control valve itself is $30+.

I'm more of a fixer type...I'd rather spend $30 than $100 on a small new one...IF...the rest is in good shape...no rust, motor good, connections, control valves, etc...

You could also use the exhaust port of a shop vac (if it has one) to do what you need (in a pinch)...

Touble is, I don't know if it's the control valve. I'm just guessing. The rest of it is in good shape. Just been sitting in the basement or garage. Hardly ever even moved.

John, put it up on the bench so you don't have to bend over; step #1.
Take the switch box completely apart and give it a really good cleaning...check the contacts for crud, and loose connections. Disconnect the cord and check it for continuity.
Once you've eliminated everything electrical, then start on the control mechanisms. Been down this road with my old Campbell Hausfield.
I did eventually replace all the air pressure activated parts but that was more of a midlife rebuild; they didn't owe me anything. My original issues were strictly electrical contact related.

John it being so old do you think it's worth fixing? This is one of those things that could go either way.

After seeing pictures on here of an exploded air tank, I'd consider the possibility of rust in the tank in my fix/replace equation.

Cheap compressors are oil-less. That means after about 500 hours, most give up the ghost. Personally, I'd just get another. Some things are repairable, some might be but aren't worth repiaring, and some things just need to be trashed. If the compressor is frozen, it's probably done. Perhaps you can revive it, but 15 years is a long run for an oil-less unit. Who knows the condition of the tank. Did you ALWAYS drain the air and any moisture in the tank. I doubt that, I am fussy and I can't claim yes to that question.

The more I do, the less I accomplish.
