Carrier Draft Inducer Problem?
Need some advice from you fine folks. I have a Carrier 58STA110-16 furnace and over the last month I have been getting noise from my draft inducer. It seems louder when the furnace initially kicks on because it is the only thing running. Best way to describe it, is it sounds like the transformer of the inducer is getting intermintent electrical surges. Simliar sound your doorbell transformer makes if you hold down the doorbell button. It gets mutted when the burners and blower kick-on, but I can still faintly hear it with the furnace cover off. I have spun by hand when the furnace is off to see if there is hesitation to spin (thinking it could be bearings), but it still spins smoothly and spins on its own when it is off, freely. I don't have any experience in diagnosticing if it is going bad or if there is a simple fix.
