My furnace makes a vibrating noise when the vent motor starts and it continues until the blower motor starts to run. It may still be there after the blower starts but the sound of the blower covers it. The noise can be heard from the registers but is not very noticable if you stand in front of the furnace.
I've removed the furnace cover and observed the vent motor and it seems to turn freely. After the power shuts down to the motor it continues to wind down at a normal rate so I'm inclined to think it may be something in the blower assembly??
Any ideas anyone?
Thanks!
Mike
