    Rated 5 out of 5 by from a nice addation to bathroom. A nice addition to our bathroom. Maintenance free from defects, cleaning is easy. the fan/light/nightlight is the correct choice for our bathroom upgrade. Sadly, it does get a little more nosier each year. It still is quite compared to the old one. thank you for a nice product.

    Rated 5 out of 5 by from This product is great! I installed this in about a half an hour; about 6 months ago. The product does all that is asked and is very dependable.

    Rated 5 out of 5 by from very satisfied with this product I purchased this product to replace our existing noisy fan. The price was reasonable and the noise performance is excellent. I don't know why I tolerated the old noisy fan for so long. I did the installation myself and found the instructions clear.

    Rated 5 out of 5 by from Both quiet and powerful I replaced a noisy bathroom fan/light combination that had failed with this Broan unit. Installation was straightforward and simple. This fan is so quiet it is literally the sound level of a whisper. It also moves twice the air that the previous unit was rated at. One of my favorite features is the ability to install a standard light bulb. The old unit used an undersized florescent that took a few seconds to light up and provided inadequate light. And it could only be replaced with the same bulb. I placed a warm white, high lumen output LED lamp in the new Broan and it lights up instantly, is very bright with good color, and it still saves energy.

    Rated 4 out of 5 by from This product ha a great light feature. This product has a great light. But the fan could use some work on it . It does not have enough pressure to run the fan properly.Also the fan is very noisey

    Rated 5 out of 5 by from Hopefully this great discontinued unit has been resurrected ! This unit has been performing admirably well for two years. My previous spring-loaded models like this would begin to rattle and make a racket after a year or so. This model is still tight and quiet. I've come to depend on the great features, including the nightlight socket. My bathroom is small, but I would only wish for a more powerful fan. Ease of installation, of course, depends on your situation - especially in old construction.

    Rated 5 out of 5 by from This top-of-the line bathroom fan performs extremely well. I've had inexpensive exhaust fans for way too long. Since I have a high-grade Viking exhaust hood for my kitchen that is very quiet, I finally decided to get a similar fan for my bathroom and purchased this model for its very low sone level. The noisy old fan did not move enough air and I had installed it incorrectly thirty-five years ago. It was driving me nuts! I purchased this back in October of 2013, intending to install it before my daughter's family paid a visit. However, I didn't have time to do this due to other home improvements and the weather was too cold to work in my attic. I finally tackled the installation a couple of weeks ago when the weather turned nice. This was a challenge, mostly because the attic space was tight under the eaves, getting comfortable in this tight and very dusty space was impossible, and drilling a 4-1.2 " diameter hole through a 9" thick brick wall was difficult to make sure it was correctly aligned to have the duct go straight from the fan to the outside without bends. In addition, the existing drop ceiling made using tools was awkward since I am elderly and not in great shape. Thankfully the fan itself was a breeze to install. My electrical skills are poor so rerouting the circuits was another challenge, not because of the three function switch itself but because the existing circuits were ungrounded and ancient. I rerouted it to a newly installed GCFI outlet circuit in another tight space within a cabinet. The installation would have been a nightmare but your instructions were very clear. I actually didn't think it would work but your excellent instructions gave me the confidence to attempt this work. I dreaded the likelihood of having to go back up into the hot attic and fix any of the installation. I was thankful that everything worked so well. After a long process of providing a new ground connection, I was delighted when everything was finally connected and I turned on the power. The fan is so smooth that the noise is like a soothing breeze; so quiet that I wasn't sure it was performing well. However, the amount of air it moves is at least three times what I had before - amazing!. It's great to take a hot shower and have absolutely no steamed windows and mirrors. My wife was frustrated at how long it took me but she was also delighted about the quality and esthetics of this fan.

  • How can I reduce sudden noise?

    It's been really noisy of late. how can I reduce the noise? Do I need to replace any parts?
    Asked by: Gee
    After opening and closing the cover a number of times, the spring-arms may lose tension. Spread them out before reinstalling the cover.

    I have the Broan triple switch to operate this fan/light/nightlight combo; do I need an additional wire run from switch to fan unit?

    I have one 3-wire line running from the switch box up to the fan housing. In order to operate the 3 switches, don't I need an additional 3-wire line that runs between the two? That way I'll have enought wires to connect like the diagram - Correct?
    Asked by: CJVA
    Thank you for your question on the model QT90L. To operate all the functions individually with three separate switches, you would need a minimum of three hot power wires coming from the switches as well as one white neutral wire and a bare ground wire.

    to install model QT90L exhaust fan can I hook it up to a standard bipole switch or do I need to use your 78v or 78w speed control?

    Asked by: Burle
    Burle: The best way to control the QT90L is to purchase from your local home center a Three Function Control Switch, i.e. Broan Model P66W which will give you indepedent control of the standard lighting, night light and fan operations. Just follow the color coding of the instruction sheet. This hook-up assumes that you have three separate feeders to the fan using flexible metal conduit with a neutral and ground conductor. If you cannot wire this way an alternative would be to wire the fan and main light together and control the night light separately.

    How do you remove or lower grill cover for cleaning

    Asked by: A
    Thank you for your question on the model QT90L exhaust fan/light. To remove the grille, pull straight down on the outsides of the grille. The grille should come down from the ceiling approximately two inches. You would then reach around the sides of the grille and squeeze the butterfly springs together to completely remove the grille from the ceiling.

    Single switch operation

    I am replacing an old ceiling light fixture with the QT90L. From the light switch to theQT90L is the standard white/black/green wiring. I believe my options are few, i.e., the fan/light/night light must all operate together, defeating the individual and separate functions, unless I were to rewire and replace the switch with one having the three functions, (more complexity than I really wanted). So moving toward the simpler solution, what is the wiring scheme with all the various colored wires, for a single switch operation?
    Asked by: Kevinaces
    Thank you for your question on the model QT90L exhaust fan/light/night light. You would want to connect all of the white wires inside the QT90L to the white house neutral wire. Connect the green wire from the unit to the green ground wire from the house. Connect the black and blue wires from the QT90L to the black hot wire from your switch and cap off the red wire from the unit. This installation will turn on the fan and light together. You will not use the night light.
