We have a ceiling fan with a light. The fan works on its own switch. The fan
light also works on its own switch. The recessed lights in the room are on a
dimmer switch. From the fan there are black, blue, white and ground wires. From
the ceiling there are black, blue, white, ground and also a red wire. What does
the red wire connect to and under what circumstances? Right now, we hooked it up
to the 2 black wires. Is that correct?

Now I use a wireless voltage detector before fooling with anything. They go
for ten or twenty bucks at Sears, and flash a light and/or beep when there's
power to the line I'm working on. I highly recommend it.
