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.

How do I know if my inducer motor is bad?
One of the first indications of a bad draft inducer motor is likely to be the sound it makes. A failing inducer motor may create a noise shortly after a heating cycle begins. This could be a tapping noise, or a humming or whirring sound.
What causes inducer motor failure?
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.
How long does a furnace inducer motor last?
A: On average, you can expect a well-built inducer motor to last around 20 years.
How much does it cost to replace furnace inducer?
Although the range can be anywhere from $85 to $1,150, the average cost of replacing a furnace inducer motor is typically between $245 and $465. When the damaged or broken part is under warranty and all you’re paying for is labor to have it installed you can expect to pay around $245.
How many ohms should an inducer motor have?
to the male terminal inside of the motor plug attached to the black fan wire. Ohm reading should be: Approx. 55.6 to 65.2 ohms.
How long does the inducer motor run?
Simply put, an inducer fan should start up when your thermostat calls for heat. It will do this anywhere from 30 seconds to one minute. What is this? It then stays running for as long as your system is heating the house and shuts off when your system cycles off.
What does pressure switch open with inducer on mean?
If the draft inducer is working properly, your pressure switch will close to complete the circuit (or “turn on”). If there is an issue with your draft inducer motor, your pressure switch will open (or “turn off ”), shutting down your furnace down by preventing it from igniting.
How long should furnace motor last?
Even though the manufacturer states their blower motor will last two decades, we advise all clients to expect a 10-20-year life span due to age, use, and proactive maintenance.
Why is my inducer motor noise?
A draft inducer (or vent blower) is the most common problem on a gas furnace or boiler to cause a noticeable noise. The small motor mounted within the housing can begin to make noise when there is buildup on the wheel (such as sulfur or creosote) or when the motor is close to the end of its usable life.
How much does it cost to replace furnace motor?
How much does a furnace motor replacement cost? On average nationwide, a furnace blower motor replacement costs $400 -$600, including parts and labor. A single-speed blower motor costs around $450 to replace while a variable-speed motor costs $600+.
