AC Fan Noise
 
I replaced the motor in my American Standard furnace/air handler last winter. It's worked perfectly until today. There is an occillating noise coming from the motor/fan area. It comes and goes. I pulled the fan and motor and checked all of the mount screws, they were ok. There is a very small amount of lateral movement between the shaft and the motor body, but I seem to remember this was present when I installed it. Any ideas?

Intermittent vibration would be unusual... I would check the fan blade for debris, dirt buildup, or a missing balancing weight... Maybe take it out and spin balance it on a nail in garage.. I had one with so much dust on it one time it would rattle picures on the wall. Cleaned it off and it ran fine.

That makes sense. I'll check it out, thanks.
