    Rated 4 out of 5 by Replacement for Generic Fan The motor in my powder room needed to be replaced. It was a generic build by the builder 25 years ago. Kudos to Broan for keeping the design constant. If I need a new complete build, I will go to them. Installation was easy (though I needed to get additional motor nuts (lock nuts). July 2, 2014
    Rated 1 out of 5 by Very low air flow Installation and motor are great. Replacement fan blade moves very little air. Simply put toilet paper infront of grill and it is easy to test the air flow, the TP barely stays up against the grill, really, seriously. November 11, 2013
    Rated 3 out of 5 by Fits but not a great fan The box at Lowes for this model (BP27) shows that it also fits Broan model #688 - A through E. As you can see from this website above Broan does not list this model. It fits and runs just like the old motor, however, I am not convinced that the fan blades (new in the box) are operating as efficiently as the original fan which is similar but has a sealed top and is a bit thicker. The shaft spline is different so the old fan blade won't fit. It does run as quiet as the original equipment. Gave it three stars as it is worth a try at only $15+/- and may work better in other Broan models. Would have liked to use the old fan blades though. May 19, 2013

    Buzzing Sound

    I just installed this replacement motor. However, the fan is not spinning and only getting buzzing sound. What can be wrong?

    Answer: 
    Thank you for your question on the BP27 fan motor and blower wheel. If this unit is installed inside a fan housing, I would check to see if something has the blower wheel bound up so it cannot spin. Please contact our Technical Service Department at 800-637-1453 for assistance.

    Answer: 
    I had the exact same thing happen to me. Swapped the motor, got everything buttoned up, flipped the switch and nothing but a buzzing sound. Took the cover down and tried to spin the wheel (I unplugged it first). Noticed it was in a bind. I took it back down and pressed the wheel further down on the shaft to where the shaft protruded about 1/8" through the top of the wheel instead of flush like the instructions said. Put everything back, flipped the switch and voila! Works just fine now. So check the wheel to ensure it spins freely when you install it.

    BP27 and 771 interchangeable?

    Can I exchange the fan wheel and motor of the 771 and fit the insert that normally takes the BP27 motor?

    I have the Motor/Wheel 663 and want to upgrade to the 771 capacity.

    From what I see, the insert is the same size and they should interchange parts.

    Do you have any information on that?

    Thank you for the question on the model BP27 fan/motor assembly. The BP27 is designed to replace the motor and fan assembly in the Broan model 662, 668, 678, 688 and Nautilus model N678 and N688 only. It is not meant to be used with any other models. These units range from 3-5/8” deep to 5-3/4” deep.

    The Parts Explosion for 678 shows two motor and tree blowers. Is the blower that comes in BP27 more efficient than the squirrel cage blower that came with my 678 fan/light?

    Answer: 
    The BP27 is the bulk pack quantity of part number 97012038. This is the motor and wheel for the older model 678 units. The label would read 678-A, B, C, D, E, or F. The pt# 97015163 is the complete motor assembly for the newer 678 units, which would read 678-G. These parts would not be interchangeable. If you have further questions, please contact our technical support department at 1-800-637-1453.
