Carrier Furnace Inducer Motor Not Running

Shows no power from circuit board for high speed post for inducer motor and not from low speed post.

Carrier furnace inducer motor not running.

Ran ohm meter on limit switches all open meter. Applied 110 v to inducer motor worked. First make sure that power is getting to the motor. 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.

If the blower motor hums check the blower fan to ensure that it spins freely. Sometimes the bad inducer motor becomes very hot to the touch. If power is getting to the blower motor but the motor does not run the motor may be burned out. 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.

If the blower motor is burned out replace it. A failing inducer motor may create a noise shortly after a heating cycle begins. And every gas furnace we make passes the legendary carrier 100 run testing for quality and reliable performance. This could be a tapping noise or a humming or whirring sound.

Jumped lower pressure switch. The first thing that is supposed to start when a furnace starts up is the draft inducer. If i use a fiberglass filter it whines when the furnace is running at high speed but not at low speed. I have a carrier 58mca furnace.

Longer low stage run times give you better energy efficiency better temperature control and increased comfort. Our forced air units can keep your home warm with models that automatically adjust as conditions change circulating warm air nearly continuously for high efficiency quiet operation and consistently comfortable temperatures. The inducer motor assembly starts slowly and if i kick start it with my hand will then spin to the required speed to start the furnace.
