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.

What is an inducer assembly on a furnace?

A draft inducer is, in essence, a small fan located inside of the exhaust flue at the far end of a furnace's heat exchanger. Electrical wires connect this fan to the furnace, such that it will turn on between 30 and 60 seconds before ignition commences.

How much is an inducer motor for HVAC?

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

When your furnace first starts up, the inducer motor turns on about a minute before the burners start up. The reason for this is so the inducer blower can get rid of any gases that remained in the heat exchanger during the past heating cycle.

How does an inducer fan work?

Exchanger. Once the heat gets warm enough your fan blower will turn on and blow. Air across the heat

What causes an inducer motor to go bad?

Most inducer motors failures are simply attributed to the older age of the furnace. In most cases, the internal bearings wear out and since the unit is a sealed unit, there is no way to repair the original motor. Instead the unit is simply replaced with a new one.

What safety protects a furnace if the inducer motor fails?

A furnace pressure switch is an automatic safety feature located near the motor. It shuts the furnace down if it senses negative pressure created by the draft inducer motor. This protects your home from dangerous backdrafting, which is when exhaust fumes are reintroduced into the system.

What does an inducer fan do on a furnace?

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.

Can you lubricate furnace inducer motor?

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.
