Can 678 support single control for fan and light simultaneous ?
Please tell me how to wire the 678 to a single switch for both fan and light together. I only have 14-2 wire...not the 3 wire cable.
if you have one of those $3.99 hot wire static electric testers that you hold up next to a wire to see if it's live (hot), that really helps. black should be hot.
if your house wiring is not up to code (no ground wiring separate from white, no ground-fault detectors), first switch off the circuit breaker. hook up the fan's green wire to its metal housing. hook up fan white and light white to house white. hook up fan black and light black to house black (hot). twist wire ends together and use wire nuts. this will be a code violation, but it will work, as long as you shut off the circuit breaker after checking for hot wires and before making any connections.

Will the 678 replacement work on a 678-A?
I am about to purchase the replacement kit for my Broan 678-A, but it is not listed. It lists: This motor has an original part number of S99080216 and works with the following Broan ventilation fan models: 659, 662, 663A, 663B, 663C, 663D, 663E, 668, 688, 678, 678B, 688, 688A, 688B, 688C, 688D, 688E.
678-A is not included
Thank you for your question on the model 678 exhaust fan. The proper fan assembly for the 678A would be part number 97012028 and the motor and blower wheel alone would be part number 97012038. Both of these part numbers can be purchased through the “Shop for Parts” link at the top of our web site page. Our Customer Service can also assist you at 800-558-1711.

I am replacing my Broan 678 got the new motor but the screw is to long.
I am replacing my Broan 678 got the new motor but the screw that holds it in place seems to long. When I screw it to make the light tight against it The screw hits the fan. So now I am not sure how to fix it. Seems easy but that long screw...
Having same problem. Fan is flush, but the top of the screw still hits the fan, locking it up. Did you find a fix? This long screw they use just seems like a really bad idea.
