    Model 678 G/2676F-A

    There is a black plastic flapper (damper?) that does not close all the way in my fan exhaust. Looks like it stays open at about a 45 degree angle on calm days and it will rock open and close on windy days making a noise. Is this normal? On cold days my bathroom is cold due to air escaping through the fan. What should I do to keep this flapper closed?

    Answer: 
    Thank you for your question on the model 678 G/2676F-A exhaust fan. The damper is required to stay open part way to finish drying out the moisture inside the duct work. We would suggest installing a roof or wall cap (where the duct exits the house) that also includes a damper.

    I would like to improve the air flow in my exhause fan. Installed is Broan 678 (50 cfm), so without changing the entire housing, is it possible to replace the fan motor and blade assembly with another to a 90 or 100 cfm assembly?

    Answer: 
    Thank you for your question on the model 678 exhaust fan/light. The only parts available for use inside the 678 housing would be the original replacement parts. If you need more CFM you will need to completely remove the 678 from the ceiling and install another model.

    Answer: 
    Thank you for your question on the model 678 exhaust fan/light. If both the fan and light work when plugged into a cord, the problem is probably a supply issue. Please contact the Technical Service Department at 800-637-1453 for assistance.

    Answer: 
    Thank you for your question on the model 678 exhaust fan/light. The motor is attached to the large motor mounting bracket (it is the size of the whole housing). There are tabs in the mounting bracket that slide into slots in the housing. You would need to pry the bracket out of the housing using a flat blade screwdriver. Please contact the Technical Service Department at 800-637-1453 for further assistance.

    Answer: 
    Thank you for your question. It is always recommended that a separate line and switch be run when installing a bath fan, however, as long as the current rating of the switch is not exceeded by both units being run at the same time, this should work fine.
