Thanks for the guide! I would never have thought to dig through the grease in the gearbox to find the 4 machine screws buried under there. Turns out that my motor is fine, but the thermal fuse strapped to the windings burned out. $5 fix for a $150 device!

I didnt see any thermal fuse

On the bottom of the motor, connected to red lead, wrapped in white shielding

My Hamilton Beach food processor stopped working. So I ordered another bottom part(motor assembly) but t it will not come on either. Are they not interchangeable?
