  • Rated 3.5 out of 5 by 26 reviewers.
    Rated 5 out of 5 by this product is a big improvement over my prior fan/light I was able to replace a similar fan/light in the bathroom without complication. my wife immediately commented on how much quieter the new one is. Since we use it a great deal the significant lack of loud noise is a relief. Now she wants me to replace the fan/light in the other bathroom with this quieter version. April 29, 2016
    Rated 5 out of 5 by This product is quality and preforms awesome! The added light feature has been a real blessing. Would recommend it as a great value and well worth the Rate this a 10. Has all the value and functionality at a great price. April 29, 2016
    Rated 2 out of 5 by Product does the job The plastic cover keeps breaking where it fits into the slot. I got a replacement one under warranty but I only removed it one time and there is already a crack that keeps growing. This cover will be garbage soon too. They wanted me to check the light bulb wattage and it is within the recommended wattage. April 27, 2016
    Rated 3 out of 5 by don't use with flat roof; no need for light it was the only one OSH sold for 4 inch duct. almost impossible to install under flat roof in 2X6 joist space. light is not needed and tungsten filament bulb will quickly burn out due to vibration. low cost and no choice was why I bought it. works as advertised. good choice for conventional sloped roof. October 16, 2015
    Rated 2 out of 5 by Cheap and NOISY Why would anyone want a very loud fan? Sure, it is cheap and people want to try it due to price. After installation, it is so loud, you wish you had NEVER HEARD OF BROAN and gone with something better. The plastic cover resonates, metal pings, and noise STATES CHEAP CHEAP CHEAP! May 17, 2015
    Rated 1 out of 5 by don't forget to prewire or you are in trouble I installed this unit and after reading the instructions was not warned to make sure the wiring was complete before the drywall ceiling is installed. There is no way to service the electric post installation. It also appears there is no way to replace the motor as the motor compartment is riveted in. Overall this unit was unsatisfactory December 10, 2014
    Rated 4 out of 5 by American made I just installed the broan 679 in my bathroom it replaced an old nutone fan only that just died. Big reason I bought this fan and light is because it's American made. Installation wasn't that bad. It's not real loud but it's not real quiet either that's why I bought it I like the noise I don't like hearing people use the bathroom. There is some things that need improved like the installation instructions separate the different languages, give rough dimensions on the sheet not just the box, and also include wiring diagram for using 1 switch for light and fan. Also the grille doesn't have a lot of play in it so you really need to be sure the have the proper depth when installing. One last thing is the grille design to take it off and clean it will you will have to remove the light reflector to take grille all the way off. Those don't hurt the product just are things that could be improved. Side note seen a bad review because someone didn't wire unit at time of install and put drywall up. Really use common sense look at unit first get familiar with it plan out install don't give negative review because of a mental error. December 16, 2014
    Rated 5 out of 5 by The Broan bathroom fan/light is an excellent value, easily installed and quiet while in use. The Broan bathroom light/fan is well designed, the instructions are easy to understand and follow. The fixture fits readily into the bathroom ceiling and takes about 1 hour to install when replacing an existing light/fan. The fan can be wired to operate either independently of or in conjunction with the light. The Broan bathroom light/fan is an attractive fixture with a strong, quiet fan that is an attractive addition to any bathroom. September 5, 2014

    I have a Broan 678 controlled by a double switch from one power source

    Top switch is for the light, the bottom switch is for the fan. I purchased your 64V switch for the light/fan and delayed fan. I went to install and the "power in" black is connected but the neutral is not connected to anything. The load wiring to the light/fan uses the black line to the fan and the white line to the light, both power in and load are grounded. Your schematics show a white neutral to/from the fan/light which I do not have. Do you have any suggestions?

    Answer: 
    Thank you for your question on the model 678. In order to operate the fan and light independently, you must have two hot wires and one neutral wire. With the wiring you have described, it would not be possible to use this switch. Please contact our Technical Support Department directly if you have further questions at 800-637-1453.

    Answer: 
    Thank you for your question regarding the model 678 and lens. You will need to know the revision letter that follows your model number in order for us to supply you with the correct light lens part number. You will find this up, inside the housing on a specification label. You will need to remove the cover to see this label. If you have your old light lens, you may find an eight digit part number imprinted into the plastic. With this information, we can assist you more. Please contact Customer Service at 800-558-1711 for further assistance. Thank you.

    Answer: 
    Thank you for your question on the model 678 exhaust fan/light. The 678 has two white wires, one black wire and one blue wire. The house ground wire would go to the ground screw inside the unit housing. The two white wires would go to the house white neutral wire. The black wire would go to the hot power wire from the fan switch and the blue wire would go to the hot power wire from the light switch. Please contact the Technical Service Department at 800-637-1453 if you need further assistance.

    Answer: 
    Thank you for your question on the model 678N-3 exhaust fan/light. The only parts available for use in the 678N-3 housing are the original replacement parts. If you need a quieter fan, you will need to completely remove the 678N-3 from the ceiling and install another model. Please contact our Canadian office at 877-896-1119 if you need further assistance.
