Inducer Fan Motor Making Noise

The fan is in the combustion exhaust stream to provide evacuation of combustion gasses.

Inducer fan motor making noise. I asked what it would take to lessen this noise. The same hvac company that installed the furnace replaced the inducer with the fasco a170 and i immediately noticed an unpleasant noise from the inducer fan motor a higher pitch like a hair dryer that you can hear throughout my house. The hvac people replaced the a170 three times they thought they had a bad batch of noisy rattling motors. A failing inducer motor may create a noise shortly after a heating cycle begins.

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. These do have a problem with noise and if it is the bearings of the motor then the usual fix is to replace the fan motor as a unit.

The draft inducer motor draws air into the burner and then exhausts it out the flue.

If the draft inducer motor is unusually noisy replace it. Once the motor fails it leaves you with a furnace that will not function not something you want to happen in the middle of the heating season. A blower motor or inducer motor on its way toward failing may also make a loud humming noise. That is the inducer fan and motor.

If the motor bearings are worn out the motor will be loud. If the draft inducer motor is unusually noisy replace it. We knew that the inducer motor was rattling very loudly anytime the furnace was on. Other than that the furnace is looking pretty good.

This could be a tapping noise or a humming or whirring sound.
