Have a 10" 3hp single phase Jet table saw. It stopped in the middle of ripping some plywood. Breaker was fine,no smoke, nothing. The only thing was it had a bit of a "kick" when I turned it on for the rip. Switch maybe? Help.

Maybe the start capacitor?
Caps are always the first and easiest thing to check.
A switch is extremely simple to meter as long as you own a multimeter. It's also a free thing to check. Then the capacitor. Do you own a multimeter?
Take a look at the heaters (overloads). You might have toasted one of them. That happened to my PM66 years ago while ripping some thick stock. I used a short section of wire to bypass the link until I could get the proper replacement.
No idea, never had this happen and I always vacuum and blow out the motor. I know the on off buttons don't seem to catch like they normally do. I've had it for about 25 yrs and it's a workhorse but not abused .
Motors ahve this stuff happen all of the time. I am state licensed as an Electrician in Ohio and have worked as a refrigeration mechanic as well. I currently work in the facilities department of a small university.
Nothing to worry about, probably a cap, overload or switch....
...and nothing related to abuse. Things get old and break. I would buy an extra of whatever you find it is so you ahve one on hand.

Beranek's Law:
It has been remarked that if one selects his own components, builds his own enclosure, and is convinced he has made a wise choice of design, then his own loudspeaker sounds better to him than does anyone else's loudspeaker. In this case, the frequency response of the loudspeaker seems to play only a minor part in forming a person's opinion.

Is there a thermal overload button on the motor somewhere?? It may have tripped and needs to be reset if it is an older motor.

Not to sound stupid but where would I look for the heaters/overloads?
Yes, but the switch unit is sealed pretty well and very little dust makes its way in. I' m thinking switch but have no knowledge or meter to test it
Don"t own one and would not have a clue......electronics are not my strong suit but I quess I might have to learn real quick.
Yes 240, know where to check in the motor? Its also a magnetic switch if that makes any differance......?
I would call Jet I have had excellent experience talking to their techs.
Could be lots of things like a capacitor or there is a centrifugal brake on the motor that may be the problem.
It would be very easy to check the switch with a voltmeter before calling Jet.
