the old fan was wired and just had two wires coming out of it to the wiring system
This one comes with tabs and the instructions say put blue on hot, white on neutral.
The new motor is not marked HOT or Neutral so you have to guess..
why not a schematic showing which wire goes to which terminal on the new motor. SIMPLE?
