3 Questions from the Community

  • The NuTone 9427P can be wired so that the light and the fan can be switched on individually.

    Can the fan and each of the 2 bulbs be switched separately (3 switches), so that 1, 2 or all 3 functions can be used??

    A. The NuTone 9427P can be wired so that the light and the fan can be switched on individually.

  • It doesn't matter what side the heat bulb is on. Just make sure the bulb heater shall be NuTone Model 9422P.

    We have one of your Nutone 9427P-R01 units and we were wondering if it matters which side has the heat-bulb. Does the heat-bulb go into the socket that is farther away from the exhaust fan?

    A. It doesn't matter what side the heat bulb is on. Just make sure the bulb heater shall be NuTone Model 9422P.

  • The NuTone 9427P can use one light and one heat lamp. The light bulb would have to be incandescent.

    Can you use this light with one heat lamp?


    The NuTone 9427P can use one light and one heat lamp. The light bulb would have to be incandescent.

Product Reviews

Rated 5 out of 5 by from saves time & money The product is perfect for replacing an older burned out product in the ceiling. Just replace the internals of the old with the internals of this new product & your done in 15 min. Tried the other route of replacing the complete unit with a new one & it makes no sense! product is a good product & have never had any problems with it.

Rated 5 out of 5 by from Dependable for years THe correct item was delivered in advance of the suggested time and was installed without a problem. Have been using this product for over 10 years and wouldn't hesitate to buy another.

Rated 5 out of 5 by from Highly recommend I replaced my old fan with the same model.

Rated 1 out of 5 by from quality worse I agree with others. I had one for 20 years and the motor burned out. Cheaper to by the whole unit instead of motor. The new one was bigger with a smaller grille. Insulation came raining down from the attic. The whole thing shook and was loud. I finally sealed around it and shimmed it tight. 2 years later the motor burned out. It never drew any air out. That's it. I'm putting an inline fan in. For 90$ it has 120 CFM. The broan unit only had 70cfm.

Rated 1 out of 5 by from whats this junk? I had an older model, same style, to remove and replace with this newer one. What a mistake. The hole had to be enlarged but the cover was smaller than the old one. It barely covers the edge and is mounted with springs that allow it to vibrate off to either end revealing the units chassis. The old one lasted nearly 12 years but this one is making noise already after a month. A waste of time and money. Next time it will be an inline fan, no nutone whose quality has steadily sunk over the years.

Rated 2 out of 5 by from Questions Do the lamps bulbs come with unit? Why isn't there a fan for just the heat lamp? Only one fan works. Also, it does not take the steam out of the shower area like the old one did. And no matter how much insulation we add to the attic, we still get cold air coming down through the unit. Any suggestions would be appreciated.
