Rated 4.6 out of 5 by 5reviewers.
Rated 5 out of 5 by Love this product. I am very pleased with this product. It works very well and the fan is very quiet. Since the fan we had before this one, (not a broan brand) was very loud, I was very pleased with this fan and light fixture. March 10, 2014
Rated 5 out of 5 by I love it It was alittle small, so o didn't think it would be effective. But I have had it a while and it is great. It does the job, it is quiet, and it has stood the test of time, thank you Groan. March 10, 2014
Rated 4 out of 5 by 678 Fan/Light, White Plastic Grille, 50 CFMGreat Product, Great product, great price, but CFM is a little too low. March 10, 2014
Rated 5 out of 5 by Replaced 20yr Broan unit I was amazed how very little this Broan unit has changed from when my house was constructed 20 years ago. The fan died in the old unit, and It made replacement very easy. I went to HD first and all they had was NuTone products - bad! (Un)Fortunately the smallest unit was 9" square and my ceiling cutout was 81/4 inch, but I was not about to create more work for me. So I went to my local family owned hardware store who happened to carry the Broan line - Yeah!. My only complaint is that there is little room for adjustment with the grill screw that connects the light reflector assembly. I had to replace it with one that was 1/4 inch longer so the acorn nut would secure it. We have exhaust again in the 1/2 bath. October 8, 2013
Rated 4 out of 5 by Good low CFM combo fan/light The unit was relatively easy to install in the ceiling of my enclosed shower compartment. I selected the lower CFM unit since it was a relatively confined space. My house configuration caused some difficulty with the vent pipe coming from the unit, but that was not a unit issue. The light output is very good and provides consistent light throughout the whole shower stall. The fan noise is reasonable, although I wish it could have been less (just didn't want to pay the higher price for the lower noise). Fan has some rattle occasionally, but not consistently. Overall, a good value for a small area that needed both light and vent. October 4, 2013

The one I want to replace has the plugs side by side. The new ones I have looked at the plugs are kiddy corner. The model 678-b must make that difference. Can you help with this

Depending on the age of the older unit there may be some differences in the wiring compared to the newer unit. If you need assistance in adjusting your wiring you can call our HVAC tech team at 800-472-4643. You may also want to consider contacting an electrician if it gets complicated.
