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 furnace inducer motor is bad?
Tapping noises are one of the most common signs of a bad inducer motor. These noises may be the result of dirt or soot collecting around the fan shaft. They might also come from the bearing in the motor clicking together. Vibrating noises are another sign of a bad inducer motor.
What happens if my inducer motor stops working?
If the inducer motor doesn’t turn on when it’s supposed to, the furnace will recognize this and shut down. It will wait a bit and try again. If the motor doesn’t start after 3 to 5 tries, the control board will stop sending voltage to the inducer motor, and essentially locking it out from attempting it anymore.
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.
Can a furnace run without an inducer motor?
The fan motor and the inducer motor are 2 separate motors. The fan can run without the inducer. What setting do you have on for fan. I think the auto setting is the one for when using heat, should turn on/off fan when heat is on.
How much does it cost to replace a furnace inducer motor?
Your furnace’s draft inducer motor removes toxic gases like carbon monoxide from the heat exchanger. The average cost to repair or replace a draft inducer motor is $200–$1,500.
How long should an inducer motor last?
Furnace inducer motors can have a life expectancy of 12-15 years. A replacement furnace inducer motor can cost around $800.
Why am I not getting power to my inducer motor?
If your inducer motor spins freely but won’t turn on, then it’s likely an electrical or power issue. If you do not have 120VAC going to the inducer motor, then you need to check the furnace’s control board: Check if the board is getting power. Use your multimeter to test for 120VAC going into the control board.
What does a furnace draft inducer?
A draft inducer is a fan that’s located inside of your furnace near the heat exchanger. By turning on before your furnace ignites its burners, the draft inducer is able to clear out any combustion gases that might be lingering in the heat exchanger from the previous heating cycle.
Are inducer motors loud?
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.
Does a furnace inducer motor have a capacitor?
The capacitor is what helps supply power to the motor when it’s first starting up. The result is not enough juice makes it to the inducer motor, and it most likely won’t start up. Or, if it does, it’s going to be weak or start and stop repeatedly every 30 seconds or so.
Will a cracked heat exchanger symptoms?
If you have a crack in the heat exchanger, you are likely to hear a rattling noise as your thermostat turns on the heat. Because the heat exchanger is made out of metal, as it is heated cracks will expand/contract, and can cause rattling, popping, and/or banging noises. Presence of Carbon Monoxide.
How long does a furnace inducer last?
This indeed is a serious component of your furnace. Just like any other motor, it can last up 20 years if used properly. The main cause of the inducer motor going bad before its time is overheating and excess moisture.
How long does it take to replace an inducer motor on a furnace?
Replacing a furnace inducer motor takes 30 to 60 minutes, depending on inspection time, accessibility, and wiring requirements.
How long does 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.
Should I replace my inducer motor?
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.
