Slicer motor really is the issue 

Did you check the capacitor? They usually go bad before a motor does. If it is shorted it will cause the motor to overheat.

I was most interested in watching the wiring at the on/off switch and the camera was not getting it.😭

Your video blurry I can't see how to reconnect on and off switch im stuck on that part can't connect my plug

my slicer Omcan HBS300 motor was very loud for months. finally stopped working. took it apart today and looks like it may have been out of alignment. now it doesn't turn on. well the switch works and it hums and doesn't spin and it's extremely hard to turn (by hand). I believe it's from hosing it down to clean it and the internals rusted. took the motor and everything out today attempting to break it loose and/or repack the bearing but I think it's beyond repair. any ideas for a replacement? thanks!
