Induced draft motor 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.

What happens when furnace inducer motor goes out?

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 much does it cost to replace a furnace inducer motor?

A replacement draft inducer motor will cost between $500 and $700. These motors are specific to manufacturers, so it can be harder to find the exact model needed. Technicians may not have the specific model on hand during emergency repair jobs at odd hours. Repairs cost less, with prices ranging from $250-$450.

What is an induced draft furnace blower?

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.

How do I know if my furnace 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 happens if the 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.

How long do furnace inducer motors last?

Furnace inducer motors can have a life expectancy of 12-15 years. A replacement furnace inducer motor can cost around $800.

How much does it cost to install an inducer motor?

The average cost of a Carrier inducer motor replacement is between $800-$1800.

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 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 the most expensive part on a furnace?

The three most expensive parts on a furnace are the blower motor, the circuit board and the draft inducer motor.

How do you fix a draft inducer motor?

Now loosen the clamp and slide the exhaust pipe up disconnect grounding wire and the draft inducer

Should my inducer fan runs constantly?

Inducer fan motor won't stop running If your inducer fan motor keeps on running all the time, it's most likely due to a tripped safety such as the high limit switch. It could also be due to a bad control board that is “stuck” in the on position for running the inducer fan.

Can you oil an inducer motor?

What is the purpose of a draft inducer?

The draft inducer is designed specifically to ensure that combustion gases are properly vented out of your furnace and that heat is distributed evenly throughout the walls of your heat exchanger.

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 is the purpose of the inducer motor 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.

How much does an HVAC inducer motor cost?
