I am not 100% sure how to wire my new bathroom fan, and I am looking for a little guidance. (This is for a NuTone QTN130LE1)

Here are the existing wires in the attic. I have a white wire, a black wire, and a ground.

Here is the wires for the unit:

Unit Wiring

There are taped into pairs

  • First pair is White and Black
  • Second pair is white and Blue
  • Third pair is White and Red
  • Fourth is ground.

And here is the wiring guide.

I am a little confused because of the red wire for the night light (Unit has 2 lights, a fan, and a night light) but I do not plan on using the night light if that makes a difference.

Any help is greatly appreciated.

  • You only have one switch? – Tester101 Jul 5 '15 at 21:19
  • The bathroom has 2 switches, one for the lights above the sink, and one for the fan/light. Only 1 switch controls the whole bathroom fan unit. The fan, and the lights in the fan. – Sam Plus Plus Jul 5 '15 at 21:21

  • Connect the black wire from the ceiling, to the black and blue wires from the fan/light.

  • Connect the white wire from the ceiling, to the white/black and white/blue wires from the fan/light unit.

  • Connect all bare/green grounding conductors.

  • Cap the red and white/red wires from the fan/light unit.

When you're done, the switch will turn on both the light and fan at the same time.

  • Tester101. Thank you so much for the quick answer. Just wired it and it worked like a charm. This is only the second question I have ever asked here and you answered both. I wish I could donate to you! Your a life saver. – Sam Plus Plus Jul 5 '15 at 21:35

    @SamPlusPlus If you want to spend some money, there's loads of good charities out there. Ronald McDonald House Charities is a good one, or Children’s Cancer Research Fund – Tester101 Jul 6 '15 at 0:09
