    Rated 4 out of 5 by Fits many other products as well As many other sites note, fan motors are very similar across a number of brands. You do need to watch for spline length and fan type. I found this unit works with a very old, discontinued vent fan by Air-o Fan - a fan unit from the 1970's and labeled as 605 for a 600 unit. However, one required change - the fan goes CW and not CCW. Happily, this is very easy to change: just remove the 2 long screws holding the motor ends together, move the pieces so it face the opposite direction and reinstall the screws. Voila, CW. Otherwise, it fit perfectly! Agree that the air volume isn't wonderful, but it's decent and saved ripping out the ceiling of the bathroom for our discontinued fan model. October 15, 2015
    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
    Rated 5 out of 5 by Good value A lot cheaper and easier to do than replacec the entire fan assembly January 11, 2011

    Answer: 
    To answer my own question the rotation has to be clockwise looking at the shaft. My fan has a side discharge, to direct air by a flapper that hangs infront of discharge, rotation has to be clockwise. Flapper will not open running CCW.

    Answer: 
    Counter clock wise (as viewed from the shaft end or looking down at the top of the fan). It is easily reversible, however.

    Answer: 
    the motor I removed is clockwise rotation. the new one is counterclockwise.which one is correct? To me, the way the impeller designed, rotation should make no difference.

    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.

    I am replacing the MOTOR ONLY in my bath ceiling fan with a BP27 motor. I am NOT replacing the box itself. The motor as is turns clockwise. However due to the location of the exhaust duct on the existing box, I need the motor to spin counter-clockwise. The motor looks like it is made to spin either way if the wires are changed. I don't know which to switch and which to leave. Please advise. Thank you

    Answer: 
    It's about magnetic polarity...
    Carefully unscrew the 2 long bolts, Carefully pull the sections apart and reverse them in the housing, bolt them back together tightly, then mount the fan...
    You can't be sloppy when you do this... maybe this shouldn't be posted...

    Answer: 
    Thank you for your question on the model BP27 motor/fan blade. If the motor is turning the wrong direction, it would not be the proper motor for your unit. These are AC motors and are not reversible. Please contact the Technical Service Department at 800-637-1453 for further assistance.

    Answers

    Answer: 
    Thank you for your question on the model BP27 replacement motor and blower wheel. The BP27 is also the single part number of 97012038. This motor and wheel combination is used in multiple units, but may not be the original motor that supplied the original sone rating. The motor used now is a replacement that allowed us to keep these units in service and supply the 50 cfm rating. This also allows the home owner to simply replace parts instead of replacing the entire unit. The models that use this motor and wheel also use different duct sizes such as 3" or 4". These differences will affect the sound and is shown by the different sone ratings on the different models. For further questions, please contact our Technical Support department directly at 800-637-1453. Thank you.

    Answer: 
    According to the Shelf Label at Lowes, it's a 4sone motor, which still begs the question how can it be a replacement for both a 4.5 and 2.5sone unit...

    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?
