Craftsman 3HP 30 GAl air compressor model no. 919.176330


compressor seems to run fine up to 30 psi then seems piston freezes up and motor cant turn it

when no pressure in it i can turn piston very freely

it builds up to 30 psi then the motor keeps running but cant turn pistons

i shut it off before blows a fuse when switch is off also leaks air out the check valve by the pressure switch but i flip handle back to on position stops leaking air

what do you think i can do

it seems be a well built compressor and was running just fine when i bought it

thanks for any help i can get where to start

So what gives? The belt slips, (burns?)

Look at the pages for runs, but will not build pressure.

I'd guess belt is too loose and/or check valve stuck open, but do your own checks.
