Can you fix a Magnetic switch - rayknight - 06-05-2019
Have a 3 year old big Grizzly bandsaw 636X 5hp, used very little, a few months ago suddenly stopped in middle of a long EASY cut, thought it was a loose misaligned upper door switch, but no. got to messing with it yesterday and resetting the thermal load switch, it hummed and tried to start, with a manual spin of the upper wheel it got up to speed fine. shut it off and now won't do anything. The magnetic switch and thermal load module are in a separate box on the back down by the motor, the key/on/off switches are in a separate position on the front, so OTC magnetic switch not an answer, and it is 30A 5hp. By their web site Grizzly does not have the complete magnetic switch/thermal load module available. Do these units fail in a predictable and fixable manner? Any shared experience, thoughts or advise?

unplug, check each connection, blow out all boxes, contact spray on contacts, etc.
Does motor have a centrifugal switch? Same treatment as above.
Next step is multimeter testing.
That's what I'd do.

If the motor spun up after a push (hopefully not pushing the blade), then I would suspect the start cap or centrifugal switch same as Wild Turkey.

+2 It is not the magnetic starter causing the problem. Roly
