Nutone 673rln fan/light combo. I have wired black to black. White to white. And red to blue. The fan works but light doesn't. Did I wire correctly?

OK, your details are a little vague, but I'll give it a shot.

I assume by this you mean you have black, white and red coming from the house wiring.
In the fan/light should be a black and white coming from each little receptacle/jack from both the fan and light. So you should have a black, blue and two whites.
I think what you did was miss the other white. Both of them must connect to the house wiring white wire.

Sorry new at this. OK from the house I have black, white, red and cooper. From the nutone fan/light I have black,white,blue and green for ground.
I hooked up black to black////// white to white and blue to red... fan works and light doesn't but light unit plugged into a wall unit to test does work there.

Is there a wall switch involved?

I ask because your power source could be at the switch. If there was a switch loop, there would be another cable in the ceiling box.

Make a quick test for us, connect the black feed to the blue (light) conductor, does your light come on? If it does, then we know the lamp circuit works. If it does not, then we know that the lamp circuit is defective and if this is a new unit, return it to where you purchased it.

If the circuit does work, you need to find out what the red conductor attaches to and why there is no power on it.

There is a wall switch yes. It's a 2 switch. 1 for the fan and 1 for the light. In the old original fan/light has 2 sets of wires (1 black/white and another black/white) and the wires coming from the wall switch up into the attic are white/black/red.

On the new fan/light there are 1-black, 1-white, 1-blue and 1-green.

Thanks for helping I will try Black to blue and test light.

Is this a bathroom fan and light combination? I just went to the Nutone website and searched for your model. Its not there. Are you sure that you have the correct model number.
I tried several fan/light combinations, none used a blue wire. All had a specialty wall switch.

Yes . Nutone 763RLN. Crossed up the numbers I apologize.

Like I said, you missed the second white. See Fig. 6 here: http://www.nutone.com/common/productDigitalAssethandler.ashx?id=42caa558-a6d0-41c1-979b-4515df84f4ba

I have this but I guess I am doing it wrong. Can you state out what to connect to what?
Thanks so much

Patrick,

Look at figure 6 in the above referenced link.

You will see that the switch is fed by a two wire cable. The Black (feed) is connected to both lower connection screws. Then one black goes to the fan and another black for the light.

However, you have a 3 wire cable. At the switch, the black from the 3 wire cable would connect to the fan position. The red from the 3 wire cable would connect to the light position on the switch. At the unit in the ceiling, black would go to black (the fan), red would go to the "blue" (the light).

Make certain that both feed connections on the switch have power going to them!

There isn't a 2nd white from the new fan/light combo

I have wired as you stated red to blue and the light doesn't work. Black to black and white to white. The fan works.

Didn't unhooked anything from the wall switch only ceiling unit wires from old fan/light combo

Patrick,

You are using an existing wall switch(s)? Please take a moment and make sure that the feed to both switches is 120 Vac. Use the black probe on the bare ground and the red probe on the black that goes into the switch (with the switch in the "OFF" position. Then make the same test on the light switch. Do both show 120 Vac?

If the answer is yes, then place the red probe on the connection that feeds the circuit. Turn the switch ON, do you still see 120 Vac? Move the red probe to the other switch, turn that switch ON and if you see 120 volts then you need to test the red conductor in the ceiling (red probe) to either the Neutral (white) or Ground (bare). If you still see 120 Volts with the switch in the ON position, the circuit is working properly and the failure is in the lamp circuitry.
