My 13" Ridgid planer quit in the middle of planing a piece. The motor just lost power and stopped as if it had been unpluged. The power source was still good. I tried resetting the built-in breaker, but this did not help. The planer has very few hours of use on it. Looked at the brushes, they didn't looked to be excessively worn. No indication of power, such as a hum, etc. What should I try next?
