Hello please excuse if I posted in the wrong spot. Nutone/Broan Whisperaire 6500c range hood with a K7448-000 motor. I have had two of these motors within a year and new fan wheels. After time it starts to rattle, so I oiled the bushings and all was good for a while. Started again so I got a new moter......lasted about two or three months same thing. Oiled it and it was good for a while. I am paying too much for motors that I may as well just junk the unit.... my 31 year old fan that the builder put in was much quieter. This thing is a real piece of junk. Is it that the bushings are actually rattling in the carrier that holds them? it seems they are held in place by a washer type spring.
I found another moter for it dubbed as the replacement for K7448-000 >>> 10941071 but it is 90 + bucks.. I have spent TOO much buying this piece of junk and buying motors that do not last. Any suggestions to quiet it up. It does not get a lot of use, but really disappointed with broan/nutone products. A waste of my money that I can not afford.
