Draft inducer motor assembly

A draft inducer is a fan that's located inside of your furnace near the heat exchanger. When your furnace begins a heating cycle, the draft inducer is one of the first devices that turns on. In fact, the draft inducer starts up 30-60 seconds before the burners are lit and continues to run throughout each heating cycle.

What happens when a draft inducer motor fails?

Although it's a fairly simple component, inducer motors have one of the highest failure rates of any part within a furnace. A failing inducer motor often creates bothersome noises and reduces the efficiency of the furnace. If it gives out completely, your furnace will be unable to provide heat altogether.

How long will a noisy inducer motor last?

Barring unforeseen issues, a high-quality inducer motor is designed to last up to 20 years. Heat and other factors can shorten its lifespan, but it's not the type of part you should replace every decade. Inducer motors are also not necessarily something easy to repair.

Can you lubricate an inducer motor?

And one motor oil three and motor one three and one motor oil is a special blend for furnace motors

What is the purpose of the inducer motor?

The inducer motor turns on and draws combustion air into the furnace. This helps to make sure the gas is burning efficiently. Next, an ignitor will either glow or spark to ignite the gas that starts flowing. This gas ignites into flames while the hot air and obnoxious gases are drawn into the heat exchanger.

Where is the draft inducer motor located?

Furnace Maintenance If the motor has oil ports, it should be lubricated annually. Apply two or three drops of 10-weight nondetergent motor oil (not all-purpose oil) to each port. Do not overlubricate. If the blower shaft has oil ports, it, too, should be lubricated annually, following the same procedure.

Does a furnace have an inducer motor and a blower motor?

It could also be due to a bad control board that is “stuck” in the on position for running the inducer fan. The first thing you need to do is turn off the power to the furnace so the inducer fan stops running. The inducer fan motor is not designed to be running 24/7– if it is, it may damage itself.
