But if you push the button and you don't hear the control clicking strongly, and releasing with the stop button, it sounds like there's an incoming power problem.  Check the top connections (L1 and L3), as they can loosen with use.  You need to get in there with your multimeter.

It's also possible the overload is tripped, though I don't know why it would trip when the saw isn't running.  A tripped O/L relay will prevent the start button from closing the main contactor since it's contact set is in series with the start/stop control.  BUT, it should be set to 'Auto' mode (the little dial in the middle).  If it's defective, nothing will happen when you push the start button.  






There should be no other junction box and/or O/L device between the control and the motor.

Thank you sir, you are a gentleman and a scholar. Yes

For perhaps future reference, I've found a non-contact voltage detector invaluable for diagnosing power issues.  I used to have to debug power recliners.

Similar issue happened to me.

Took some time to diagnose, but in my case, turned out to be an invisible, internal break in one of the power lines. The wire was separated inside unbroken insulation. 

As I said, took some time to find!

So was this problem ever fixed?
