921.164710 runs about 10 minutes and shuts down.

( North Bend Wa.)

I have a craftsman oil less 921.164710 compressor.


It will pump up to 50-60 lbs and shut off or if you turn it on with the air just exhausting straight out the air hose connection with no
attempt to build pressure it will still run about the same amount of time and shut off. (10 minutes +or-)

I have replaced the pressure switch and both the start and run capacitors .

There doesn't seem to be anything getting hot or a burnt smell.

Any help would be appreciated.

921.164710 motor breaker?

Presumably, you've had this a while, and it was working OK?

If the pump is working, it should only run a couple of minutes before shutting off at 150 psi, according to the specs.

Even with the pump unloaded, ten minutes may be enough to overheat it.

And you don't have it on an extension cord other than specified in the manual, right?

You did check for pipe leaks already, yes? So, the pump must be leaking, probably the piston seal or maybe head gasket is blown.

Good luck.
