  • Rated 4.3 out of 5 by 19 reviewers.
    Rated 5 out of 5 by Excellent product! This house had an old exhaust fan in the wall that was noisy and not taking out the moisture at all. We had some work done in the main bathroom and bought this fan as a replacement and my contractor installed it in the ceiling where it belonged in the first place. It is powerful and I love having the light and the nightlight together in one place. I would highly recommend this one. February 8, 2015
    Rated 5 out of 5 by does the job! The fan makes quick work of all steam in the bathroom within a few short minutes. Fan is quiet, light feature is bright. February 7, 2015
    Rated 5 out of 5 by Quite and does a great We needed a high volume fan for the master bathroom. This combined with light swith with a timer has fixed all our moister problems. Fairly quiet and easy to install February 6, 2015
    Rated 3 out of 5 by Overall expensive for the value Sound level not as experienced in store. For the cost, disappointed with the sound level. February 6, 2015
    Rated 5 out of 5 by Works great! Not easy to install as a replacement. But...once you get it in, it's quiet, and works great. Can take a hot shower till my 50 gallon water heater is empty and still have a clear mirror. That does it for me. February 6, 2015
    Rated 4 out of 5 by Great Product, Quiet and Efficient The product worked as advertised, quiet and pwerful. February 6, 2015
    Rated 4 out of 5 by Good styling Performance is good, styling is good, had it installed for the past 8 months, so far so good. Like the night light feature. February 6, 2015
    Rated 4 out of 5 by It's really meant for a new install... As mentioned elsewhere, this model is best suited for a new installation before the drywall is in. I bought it because it is quiet and the existing cutout was pretty large. When I opened the box, I realized the enclosure has 2 flanges on one side to screw into the joist along that side. They are each about 1.25" wide. Therefore the cutout would have to be a lot larger than the box itself. In addition the vent exit is pretty bulky, especially if you use the included 6" to 4" reducer. The only way to orient this is with the vent exit in the direction of the joists. Thankfully I could do this. To make it easier I also put the electrical wiring through the top, rather than the side of the unit. I had to bend the flanges flush to get this thing into the cutout. There are some small reinforcement bumps at the base of the flanges to cut in order to bend the flanges. If you cut the flanges off then there isn't much holding the one side of the box together. I used a suspension cord to help suspend the unit while I was wiring it up, as my ladder isn't tall enough to serve as a table for the unit. Since I didn't want to add any wiring for the nightlight feature, I simply didn't wire the nightlight in. You need another switch and wiring for that. Once I had it wired, I turned the breaker back on and tested it before installing the box in the ceiling. Thankfully it worked perfectly so I could install it. It needs securing on 2 sides if you don't use the flanges to get it to hang right, so be sure there's a second support or it will sag. I used aluminum tape to secure the 6" exit to the duct connector. Just before inserting the unit I taped the reducer to the connector, since it doesn't lock on. I had to do some tidying up of my ceiling since you can see the gaps between the unit and the drywall through the grate slits, and I also had to do a bit of spackling to repair my ceiling from the removal of the old unit, adding to the time. All in all it took me more than 2.5 hours to wrangle this in. I'm torn about recommending this: it works great, it's a lot quieter than my old, loud, non-functional Fasco units. The included type GU24 base CFLs are a bit bright for my powder room, and they're odd bases. I'll have to see what I can do about them to tone it down a bit. On the other hand, as a replacement unit it's hard to recommend this. Overall, yes I recommend, but you might have to improvise to replace your old unit. I wish it were designed for that as well as new install, and they had some creative engineers to make the task less of a chore. January 11, 2015

    We have our fan and light separated to different outlets so that we can dim the lights on a dimmer, and then wired the fan portion to a spring wound timer. I want to use incandescent bulbs for this. 1) CAN I? and 2) what is the maximum wattage for the bulb?

    Answer: 
    Thank you for your question on the model QT140LE exhaust fan/light/night light. The only bulbs recommended for the QT140LE are the 18 watt maximum, type GU24 fluorescent bulbs with a maximum overall length of 3.9”. It also uses a 4 watt maximum, type C7 incandescent night light. We do not recommend using any other type of bulbs in this unit.

    Answer: 
    Betsy, I have same issue and will probably use a lower wattage with warmer color GU24 bulb (2700K ~ incandescent) as I have a larger light already in the bathroom. I might even just just one bulb. I plan on using the vent light for winding down at night or to contrast the bright 4100K light I already have. There are GU24 to Edison Base adapters but then you'd have to find a specialty bulb short enough...not worth the trouble.

    Although they recommend incandescent C7, I use LED C7 for other bathroom night lights and they don't get hot and will last a lot longer! Note, all CFLs have poor reliability and take time to brighten.

    Answer: 
    The night light incorporated in the QT140LE requires an additional wall switch and associated wiring to function. This model features a fan, light and night light and requires 3 switches and wiring to function properly. If you need additional assistance, please contact the Broan Technical Support group at 800-637-1453.

    Answer: 
    You will need to have a separate switch with wiring in order to use the nightlight. You will also need separate switches for light and fan if you want them to run independently.

    breaker trips

    I installed this with a 3 control switch that has 20 amps with 15 amp max per switch. I turn on the fan or light and the circuit breaker trips. I turn on the night light and it doesn't trip. Can you tell me why?

    Answer: 
    Thank you for your question on the model QT140LE exhaust fan/light/night light. If you have access from above (attic or crawl space) the installation should not be too difficult. If you do not have access from above, you would need to tear out more ceiling than would normally be needed and patch the ceiling after installation. For further assistance please contact our Technical Service Department at 800-637-1453.

    Thank you for your question. Unfortunately, we are unable to assist you with this request as this is not a Broan switch. You will need to contact the manufacturer of the switch for more information.
