So my Craftsman Professional 351 series cabinet saw seems to have stopped working and I could use some help diagnosing and fixing the issue.

It started to not turn on when I pushed the on button and sometimes I would have to push it twice. Then it would act like it wanted to start, but wouldn’t. The blade would attempt to start turning but then it would either give up and I would have to push stop and start again to get it going or it would not start at all. Now it isn’t doing anything when the start button in pushed. It is currently wired for 110v.

Any ideas on what it could be? Switch maybe? Or motor issue?

Could be bad on/off switch or bad start capacitor or centrifugal start switch to engage the start capacitor.

Use a multimeter to measure the on / off switch resistance. It should be under 10 Ohms.

My multimeter has a capacitance measurement function. Measure the motor capacitance. It should be within +20% / -40% of the printed value.

The symptoms sound like a switch.
