Blade stopped turning when cutting wood after motor began to labor. I turned off the switch, checked the breaker, the electrical outlet and all worked, except the saw. Does the saw have an internal breaker or fuse that will blow before the motor goes? If not, does it sound like my motor has gone? Manual identifies one part that may be the motor. It is listed on page 27 of the manual as I.D. NO 1502 but the description is “Field Ass’y”. Is this the motor part number? If not, what is the correct P/N?
