Carrier Furnace Inducer Motor Does Not Start

The result is not enough juice makes it to the inducer motor and it most likely won t start up.

Carrier furnace inducer motor does not start.

If the pressure sensor switch does not sense operation of the inducer motor within 10 seconds however the processor aborts the start up sequence and the burner does not light. 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. This problem of getting a humming noise along with little to no spinning is very common with motors that do not have good quality capacitors. If you kill power going to the furnace and try to restart will the inducer motor try to start.

This could be a tapping noise or a humming or whirring sound. 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 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 first thing that is supposed to start when a furnace starts up is the draft inducer.

All modern microprocessor controlled furnaces by manufacturers such as carrier include a self diagnostic procedure to test the function of the inducer motor. A quick test of your capacitor can tell you a lot. I have performed the equipment test. If your furnace blower motor hums when it s switched on but at the same time does not actually turn the capacitor may be damaged.

A failing inducer motor may create a noise shortly after a heating cycle begins. The first thing that is supposed to start when a furnace starts up is the draft inducer.
