For a fan-light-heat unit to work you'll need three hot wires from the
switch and one neutral. It appears that you don't have a four
conductor cable which would have white red black and blue wires, but
instead you have two two wire cables, so you've got two whites and
two blacks. One of those whites is the neutral and the other is the
hot from the switch that goes to the blue wire in the unit.

Another example of why you should mark both ends of the wires when you
do this kind of wiring.


ALL the 120V & 240V wiring in my house is like that (12/2 romex). The
wire between 2 3-way switches uses black & white. So does the 240V
wiring. None of it is labeled. I guess the builder (I don't know, I
didn't buy the house new) used what was cheaper.

I'm removing an old bathroom fan/light/heater combo unit and
replacing it with a new one. There are two sets of wiring coming in
the box, one from each side. It's the same setup as the old one.

Here's the problem. The wiring worked fine on the old box. Now when
I hook up the new box, the side that controls the heater is fine,
but I'm not getting juice on the side that controls the fan and
light. I confirmed the fan and light both work. One catch - I have
the white hooked to white, and black to black, but there is a blue
wire "left over" coming from one of the plugs in the box. It says
attach it to a red wire, but there is no red wire in the romex set.

I don't know if the blue wire is the key, but it seems like I'm not
getting juice in that romex set of wires. This is odd, because
nothing has changed. The circuit breakers are fine.

Help!!
