Longer low stage run times give you better energy efficiency better temperature control and increased comfort. Backed by the intelligent infinity control and a variable speed blower this two stage furnace will run in low stage up to 90 of the time. Shows no power from circuit board for high speed post for inducer motor and not from low speed post. If i use a fiberglass filter it whines when the furnace is running at high speed but not at low speed.

And every gas furnace we make passes the legendary carrier 100 run testing for quality and reliable performance. If the blower motor hums check the blower fan to ensure that it spins freely. If the draft inducer does not start then you probably either have a thermostat thermostat wiring problem electrical problem control board problem or a bad draft inducer.
