Table Saw Motor Keeps Tripping Circuit Breakers


Our 40 year old Sears Craftsman table saw is now unusable. It started tripping the circuit breaker of whatever circuit outlet it's plugged into. I'm guessing something is causing it to draw too much current, which trips the breaker?

It's motor model no. 113.12170, 1 hp., capacitor start, 115 volts, 60 cycles, 3450 rpm.

Over the years it has had little use. At Sears website they don't have many parts listed as available for this motor because of it's age. I wonder if a shop could repair it?

You may have a breaker that is weak. Try replacing the breaker with a new one and see how that goes. Inspect the wires on the saw especially around the plug, switch, and the motor.

Check your breakers and make sure they are 14amps or more in order for your table saw to work. Anything less would trip.

I know it's not the breaker. I ran a 3 hp. air compressor today off the same circuit I last used the saw on. The saw trips the breaker regardless of what circuit it's on. I've tried several.

Then I would check your wiring for any lose connections that would cause a short.

Try replacing the capacitor. If its as old as the rest of the saw, it's probably time for a new one.
