bp51 and bp28 both look exactly like my part.
I have a very noisy motor in my bath fan, that I know is a broan. I want to replace only the motor, since it was a big pain when I replaced the whole assembly 13 years ago.
bp51 and bp28 both look exactly like my part. how do I know which is correct?
This turned out to be the easiest solution:
I removed the motor, and disassembled it. I then lubricated all of the bearings with 2-stroke motor oil additive (the blue stuff). I put the motor back together, and it as quiet as the day I first bought it.
