"Vibrating Furnace" , posted Mon 20 Oct 13:28

Hi, I have a 15 year old Coleman Furnace. It has performed well for years and continues to do so, but I have a slight problem lately.

I noticed the ductwork is shaking a bit after the burner shuts down and the blower is going through the "cool down" process. The motor is fairly new and it seems tight. I'm thinking that the blower wheel is out of balance. I cleaned it and oiled the motor, but it didnt help much. Also, rubber mounts appear to be in good condition and are tight.

Any suggestions???
