Carrier Furnace Inducer Motor Not Running

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.

Carrier furnace inducer motor not running.

The first thing that is supposed to start when a furnace starts up is the draft inducer. Jumped lower pressure switch. I have a carrier 58mca furnace. A bad furnace inducer motor can result in a loud buzzing or whining noise and loss of heat.

Ran ohm meter on limit switches all open meter. If i use a fiberglass filter it whines when the furnace is running at high speed but not at low speed. 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.

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

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

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