Saw bound up going thru some 10/4 Ash. Really doesn’t take much to bind this saw up, still it is great for rough slicing and dicing. Reset button remains in the down position, never popped up. I should mention that this saw is set up for 11o v. I took off the cover and have checked the pop up reset for continuity and its fine, all the wires going from the board to the switch are fine including the black wire going into the Mallory coil. I checked the copper thermal break on the shaft and it too shows continuity. I have also taken the switch cover off and checked for voltage, which is good down to the board in the motor. 
The saw stopped almost immediately, no smell of burning and no indications of over heating anywhere on the motor.

Looking for ideas on where to check next. Like I said it is a good saw, bought it at Habitat for Humanity for $250. I build cabinets and basic furniture for a living so it is great to rough things up.
