Carrier Furnace Inducer Motor Not Running

Carrier furnace inducer motor not running.

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. Longer low stage run times give you better energy efficiency better temperature control and increased comfort. If the blower motor is burned out replace it. 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.

I have a carrier 58mca furnace. 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. Ran ohm meter on limit switches all open meter. If the blower motor hums check the blower fan to ensure that it spins freely.

Shows no power from circuit board for high speed post for inducer motor and not from low speed post. This could be a tapping noise or a humming or whirring sound. A failing inducer motor may create a noise shortly after a heating cycle begins. 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.

A bad furnace inducer motor can result in a loud buzzing or whining noise and loss of heat. Sometimes the bad inducer motor becomes very hot to the touch. If i use a fiberglass filter it whines when the furnace is running at high speed but not at low speed. First make sure that power is getting to the motor.

And every gas furnace we make passes the legendary carrier 100 run testing for quality and reliable performance. If the unit will turn on but the blower motor is not turning on there are a couple of ways to check if the draft inducer motor has gone bad. No power to the inducer motor from the circuit board checked limit switches all are open.
