919.167312 Breaker Blows
by Rex Gray
Plate showing Craftsman model
I have a Craftsman 30 gal compressor, model 919.167312 - which I've had for several years, and had good service - until recently.
Usually the breaker would trip after it had been running for some time,after getting up to 70-80 lbs under no load (It leaks air, probably around hose connections, so after no use for a week, the air is pretty much all gone).
Recently, the breaker trips after just a few minutes, not even getting to 20 lbs.
Noticed a really strange smell - not like electrical, burning, etc - just a pungent odor. may not be related but...I pulled the cover off, as well as the back cover of the motor (see pics).
Did not see anything unusual (corrosion, bearing/brush dust, etc).
Have not replaced anything yet (check valves, etc) - just in case it might be the motor going. If it is the motor, any obvious symptoms to check (short of taking it somewhere to check).
