Bryant Plus 90 furnace Inducer Motor Noise

QUESTION:

Our Byrant Plus 90 furnace, installed in 1992, has developed an intermittent noise in the inducer motor that interferes with normal furnace operation. The symptom is loud "vibrating" type noise when the furnace is attempting to fire up to heat the house.
When I hear it the sound, I can open the furnace door and lightly tap on the inducer motor, the sound goes away and the furnace then proceeds to work normally. Then, anywhere from 1 to 10 days later, the same thing happens again..
My questions are: What do you think is going on? What would be the appropriate repair? What would the repair typically cost? Repair to be done by a professional, not by me.

ANSWER:

Sounds like the motor is going bad. I paid about $130.00 for the part itself, and changed it my self. That was on a different model furnace though. Maybe around $200.00-$250.00 for a HVAC company.
