i have a 21gal 3hp compressor . it wont do anything i wired around circuit breaker fan turns starting cap is not damaged or leaking.
Richard, one link from the TROUBLESHOOTING page is "compressor will not start". There's a lot of info there about why this situation occurs.
Why not have a read, check out some of things that it says, and then post a comment here telling us what didn't work :-), and then maybe we can narrow it down a bit.

Harbor Freight # 94355 compressor leak in top of pump head
by Ron Shimek
Plastic lid off
Harbor Freight # 94355 8 gal oiless compressor
Air leak on cyl head. Not from gasket. Looks like small hole in center of the top of the head
Ron, you must have removed the plastic shroud to get to the head?
I am looking at the manual and I don't see where you might have a leak.
Air is not bleeding out of the pressure switch at the rear, is it?
I'm wondering if the hole you refer to is the intake port? If air is huffing out that hole as the compressor is running, then you have a failing or failed intake valve.
Could you start a new thread and upload a photo showing where this hole is?
As you can see from the photos, my problem is in the head. I can't quite see without further disassembly exactly what the leak is, I suspect a small pinhole or porous metal leak?? It leaks continuously when running or when off. Maybe some sort of compression release for startup that has a sticking reed valve?
Ron, I too suspect a poor casting might be the problem.
Thank you for taking the time to repost, and to upload pictures.
Folks, anyone else have this type of problem with the head on a Harbor Freight Air Compressor.
