Carrier Furnace Inducer Motor Not Running

A failing inducer motor may create a noise shortly after a heating cycle begins.

Carrier furnace inducer motor not running.

If the blower motor hums check the blower fan to ensure that it spins freely. I have a carrier 58mca furnace. Applied 110 v to inducer motor worked. 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.

Sometimes the bad inducer motor becomes very hot to the touch. And every gas furnace we make passes the legendary carrier 100 run testing for quality and reliable performance. A bad furnace inducer motor can result in a loud buzzing or whining noise and loss of heat. The first thing that is supposed to start when a furnace starts up is the draft inducer.

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. No power to the inducer motor from the circuit board checked limit switches all are open.

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. This could be a tapping noise or a humming or whirring sound. Ran ohm meter on limit switches all open meter. Jumped lower pressure switch.

First make sure that power is getting to the motor. 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. If power is getting to the blower motor but the motor does not run the motor may be burned out.
