Question, what is considered a variable speed motor or furnace blower/fan? I
have a furnace that has variable speeds, one higher speed for when the air
conditioner is on then there is a couple speeds for when the furnace is on, one
lower, one higher when demand is greater, is this considered a variable speed
blower or fan? The furnace that I have produces no RFI that I can detect.

I have a variable speed American Standard 4A6V8048a1000a and I cannot tell you
how noisy it is. We put ferrites on the control cable and that seamed to help
and ferrites on the AC cable with little help. They actually vibrate. Work in
progress but it is not good.
