I just bought a used Jenn-Air Convection Wall Oven - Electronic Control. We are trying to connect it however we don't have a wiring diagram for it. What's throwing us for a loop is the extra blue wire. Do you know what that wire is for?

Does it need a seperate fuse box like our counter cook top has?

A Model Number may help others help you.

Where is it, what is it attached to? Just need a better descriton of the problem.

It should be on a separate line. With a Model Number I may be able to find an install sheet. This also depends how the kitchen is set up and the house wiring and of coarse the local electrical code.
