I have a thermal zone furnace #GU100M16B. The motor (part #902128) makes a buzzing type sound before the blower starts. Is this an indication the motor will be going out soon? There's also a run capacitor mounted on the side of the blower housing, can the sound have anything to do with it?
Please advise

During this time of year it is very important to have the furnace working properly and not making any strange noises. While you are waiting for an expert answer, I did manage to find a link that describes a similar problem to the one that you are having. I am also including a second link in where you can enter your model number and your owners manual will pop up so that you can look in the trouble shooting pages. I hope my links are useful.
