Today after ripping through 6 sheets of 3/4" plywood for cabinets, my Grizzly GO691 table saw motor is having some issues. I started it up to make my last cut, and it turned very slow and made some weird noises. I would describe the noise as a slight grinding, bogged down noise. I would say the motor was running at about 1/10th the speed it normally does. It was almost like there was some extra resistance on the motor not allowing it to spin up. I haven't had put much time into trying to diagnose the issue, but I did check that the blade rotates freely and blew out the motor on the fan side. There were no bad smells to indicate that something burned up inside the motor. The table saw was purchased new in about 2010. Any suggestions on what to check for?
Thanks in advance,
Kyle
