I have a Bostitch air compressor that suddenly started tripping breakers and starts then stops immediately. It says "oil free" which, I guess means there's no oil to check.

Any suggestions on what else I should check? it's done this in multiple locations and I'm not using an extension cord. I'm not opposed to replacing it but, I always like to try to fix things first.

Maybe the piston locked up?

Does it have start capacitors?

If this isn't some high dollar compressor, just go get a new one.

If this is one of those little pancake compressors that come as a kit with a trim gun or something then just toss it. These are truly $100 throw away items now, not like the old Porter-Cables that you could buy for $100 and run on a trim crew and they just didn't die for years on end.

This.

I chased a leak and then went through a couple switches before I realized how stupid is was to even try to fix it.

I'd atleast take it apart enough to see if the rotor will spin freely. If it doesn't then see if the piston is hungup. See it its something obvious. Nothing to lose.

Well, if you can't fix it, check out Lowes. They have a 6 gallon 150 PSI pancake compressor with 3 guns and 25 ft. of air hose for $199.

The nailers include a 16 gauge finish nailer, an 18 gauge brad nailer and a 23 gauge pin nailer.

A surprisingly effective repair technique that has served me well over the years is to bang it (whatever you are working on) with a hammer (or hammer like implement like a scrap of wood). This technique is best used after some basic pokin' at it techniques have failed.

If it's pulling enough amp to trip the breaker now, it's probably lost a bearing or the teflon seals that rung the piston have failed. It will cost more to buy the parts and resurface the bore than it's worth to fix. Better off buying another one or, if you actually want something that will outlast you, get sonething like a Makita MAC5200. Oil-lubed compressors are quieter, last far longer, and with good synthetic compressor oil are basically set for years with the level of use an average DIYer will put on it.

We pros call this "percussive maintenance." it works on a surprisingly large number of mechanical devices. my current hack is slamming the glove box door on my 2008 Tacoma to make the heater fan work.

Follow-up question.

How do I get rid of the old compressor? It's not like I can just put it in a trash can. I don't think the landfill will accept it. What do I do with it?

Leave it out of trash for pickup. Someone will come by and get it before you even know it. Scrap steel.
