Where can I find the electric motor for this hood?A. The motor you will need for your Broan 4121 depends on the letter you will find on the spec label. It will say "41000-X" where X is the letter. If it does not have a letter or has A-C, you will need the S99080103. If it has D-J, you will need the S99080200. If it has K-L, you will need the S99080365.
Does this come with everything needed for successful installation and use (aside from the light bulb)?A.
The Broan 4121 does come with everything to install except the vent pipe and light bulbs.
