    Answer: 
    Thank you for your question on the model 670 exhaust fan. The 670 requires a ceiling cut out of 7-1/4” x 7-1/2”. We have numerous exhaust fans that would require a ceiling opening of approximately 10” x 10”. Please contact the Technical Service Department at 800-637-1453 for assistance.

    I have an old Broan 663-B/688-B A-Housing 8″ x 8-1/4″ and the damper flap hing broke. Where can I find a replacement? Possibly made of metal this time but anything will do.

     on 688
    I have the older 663C/668C model that produces loud noises when running. I'd like to try cleaning it before buying any replacement parts. What is the process to clean the motor and blower? I also have the 162-C model that I'd like to clean out as well.
