Inducer Motor Furnace

If your furnace is making strange noises or refusing to start, the problem could be with a small but vital component — the furnace inducer motor. This motor plays a crucial role in keeping your heating system safe, efficient, and compliant with emissions standards.
At HVAC Tempe Pros, we help homeowners across Tempe, AZ understand and maintain their heating systems. In this guide, we’ll explain what a furnace inducer motor does, common signs it’s failing, how it’s replaced, and why calling a licensed HVAC technician is always the safest move.

🔍 What Is a Furnace Inducer Motor?The inducer motor, also known as the draft inducer motor, is a small electric motor that starts running right before your furnace ignites. Its job is to clear out exhaust gases left over from previous heating cycles and create proper airflow for the combustion process.
Think of it as a “starter” that prepares your furnace to burn gas safely. It ensures carbon monoxide and other harmful gases are vented out of your home before ignition begins.
Without it, your furnace could release unsafe fumes into your house or fail to ignite altogether.

⚙️ How the Furnace Inducer Motor WorksHere’s what happens step-by-step when your thermostat calls for heat:
  1. Thermostat Sends a Signal – Your thermostat tells the furnace to turn on.
  2. Inducer Motor Starts First – The inducer motor kicks in, pulling air through the heat exchanger and venting any leftover gases.
  3. Pressure Switch Activates – Once enough airflow is detected, the pressure switch closes.
  4. Ignition Sequence Begins – The gas valve opens, the burner ignites, and warm air begins circulating through your home.
If the inducer motor doesn’t start or doesn’t create enough draft, the pressure switch won’t activate — stopping your furnace from firing for safety reasons.

🚨 5 Signs Your Furnace Inducer Motor Is FailingA malfunctioning inducer motor can cause your entire furnace to stop working or behave erratically. Watch for these warning signs:
1. Unusual NoisesIf you hear loud humming, rattling, or grinding sounds right before the furnace starts, the motor bearings could be wearing out.
2. Furnace Won’t StartWhen the inducer motor fails, your furnace won’t ignite. You may hear a click from the control board, but nothing else happens.
3. Short CyclingIf your furnace starts and stops frequently, a failing inducer motor may be causing the system to overheat or trigger safety switches.
4. Burning SmellA motor overheating due to age or electrical issues can emit a burning odor, signaling imminent failure.
5. Error Codes or Flashing LightsModern furnaces display diagnostic codes on the control board. An inducer motor or pressure switch fault is one of the most common error messages.

🧰 5 Top Causes of Inducer Motor Problems?Several issues can cause an inducer motor to fail or underperform:
Because the inducer motor is directly tied to your furnace’s combustion and exhaust process, a failure should always be addressed promptly by a professional.

❓ FAQ on Furnace Inducer MotorQ1: How long should a furnace inducer motor last?
Most inducer motors last 10–15 years, depending on usage and maintenance.

No — most modern motors are sealed units. Lubricating or opening them can cause damage and void warranties.

If your furnace is over 15 years old, replacing the entire unit may be more cost-effective than repairing it. Our technicians can evaluate your system and advise the best option.

The furnace won’t ignite. This often happens when the inducer motor isn’t pulling enough air through the exhaust system.
Q5: How can I prevent inducer motor failure?
Schedule annual furnace maintenance to clean vents, check electrical connections, and inspect moving parts. Preventative care keeps your motor running smoothly.
