Hi,
I got a new Heil (ICP) furnace for my little brick bungalow last spring. Heats OK (so far).
With Tstat calling for inaction, it sits there and hums. I flip the shutoff switch and the hum dies.
Gotta be the transformer? I don't recall a transformer hum with previous furnaces.
Is this normal? Doe it make a difference if the transformer is Honeywell?
Thx, Puddin'
