    The bottom center circuit breaker jumps after 30 minutes of cutting. I dont get any errors.

    Any ideas why this is happening?

    the electric motor has a broken fan and making noise..could this be the problem?. overheating..

    Remove the straps. Check the bearings by turning the motor by hand. Listen carefully, crunching, humming, jamming, these are all indications for repair.

    Hi sir;

    Please look in Q 97 Overload switch for main motor, for loose wires, AND TIGH VERY WEll, look for OXIDE in the terminals, or broken, and adjust the Pot a little more Higher Amps.

    By other side, if the broken fan is broken, is time to Maintenance complete for the Main Motor, exchange bearing, Lube, clean it. and Put a new Varnish, since the winding can be Reheating ( NOT BURNING).!
