  • Rated 4.3 out of 5 by 22 reviewers.
    Rated 3 out of 5 by Good features, best on the market It appears to be a good product, very quite. We had trouble on the installation, it was blowing back, rather then venting. (half the unit?) Once we changed to a 6" duct and ran straight out from unit, it corrected the problem. July 17, 2015
    Rated 5 out of 5 by Great Bath Fan I replaced an existing inadequate bath fan. I also wanted more light over the bath tub/shower and couldn't navigate the attic to where it would need to be. So I opted for this unit which also had a light. It was difficult to install only because I had to get into the attic and climb over and around AC duct work and through heavy fiberglass insulation trying to locate the beams to stand on. I also needed to work on my stomach since the existing fan was near the eaves. Be cautious if you do not have a multiple switch for this since this model has a fan, light and night light. You must splice the light wiring to the fan wiring for the light to work. If you splice the night light wiring in also, you will have the night light on with the other lights whenever the fan is turned on. April 30, 2015
    Rated 5 out of 5 by Love it ! Cost a little more than I would like but......installed 4/9/15 and first time since 1999 I was able to take a shower with the bathroom door shut and no steam and foggy mirrors.....works great ! April 10, 2015
    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

    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.

    Answer: 
    If you used the 6" exhaust duct, it should operate at 1.5 Sones. If you used the reducer from 6" to 4" the Sones level will be higher and the CFM slightly lower. Unless there is a problem with the fan turning freely, it should be fairly quiet. It also depends on the specs of the fan you replaced.

    Installing on one single pole light switch

    I only have one single pole light switch with a black/white/red/ground wire.

    I do not want to use the night light function.

    Which wires should I connect to the black/white/red/ground?

    Thanks.

    Answer: 
    Thank you for your question on the model QT140LE exhaust fan/light/night light. The bare ground wire from the QT140LE will go to the house bare ground wire. The three white wires from the QT140LE will go to the house white neutral wire. The black and blue wires from the QT140LE would go to the hot power wire from you wall switch. Cap off the red wire from the QT140LE. When the switch is turned on, the light and fan should come on together. Please contact the Technical Service Department at 800-637-1453 if you need further assistance.

    Answer: 
    Look at the wiring diagram in the installation booklet. You should use the Blue/White wires for the light. The Night Light uses the Red/White. Splice the Blue with the Black from the fan and connect them to the Black wire from the switch. Connect the whites to the white from the switch. Connect the Green from the Fan to the Bare ground wire.

    Answer: 
    Look in the installation booklet. It shows you should use a small flat blade screwdriver on either side, long side, of the lens and gently pry it off one side. The other side will pop out. The bulbs are special so be sure you get the correct bulbs for it.
