My old furnace responded to the Fan position on the thermostat by just leaving the fan on at all times, even when the furnace was heating.
My new furnace doesn't operate that way any more. When it gets ready to fire up the burner, it stops the main blower completely for quite a few seconds, then starts the blower again.
I have been told that this is so a two speed blower can switch speeds, or because the burner requires it. The latest news I've been told is that all modern computer controlled furnaces do this.
I liked it the old way and hoped I could get the installer to make it run the fan continuously.
The furnace is a Maytag RC-80 furnace.
The manual seems to say that the Fan position should cause the furnace to always run the blower. So who's right?
