Inducer motor fan noise

Bryant 355CAV, inducer 340792-762. Rattles on start up. 10 year old furnace, guessing bearing are bad, sealed of course. Water drains ok, no fan noise rubbing, just rattleing motor sound

What's the question?

Sounds like it needs a new inducer.

It could be prohibitively expensive due to being ecm - i looked up the model. Unfortunately you have one of the most expensive to fix units on earth.

Your style furnace has secondary heat exchanger issues and it needs to be checked before spending money on parts. You can search this board for more info - lots of threads about it.
