What happens when the blower motor goes out?
When the blower motor in your HVAC system fails, it can have significant consequences for the overall functioning of your heating and cooling system. The blower motor is a critical component that plays a vital role in circulating air throughout your home or building.
Understanding the Blower Motor's Function
The blower motor is responsible for drawing air from the return duct and pushing it through the supply ducts, which then distribute the conditioned air (heated or cooled) throughout the living space. Without a functioning blower motor, the HVAC system cannot effectively circulate the air, leading to various issues.
Symptoms of a Failing Blower Motor
- No air flow from the vents: If the blower motor is not working, you'll notice a complete lack of air flow from the supply vents, indicating a problem with the motor.
- Reduced air flow: A partially failing blower motor may result in reduced air flow, making it harder to maintain the desired temperature in your home.
- Unusual noises: A malfunctioning blower motor may produce strange noises, such as grinding, squealing, or rattling, as the motor struggles to operate.
- Increased energy bills: Without a properly functioning blower motor, the HVAC system has to work harder to circulate the air, leading to higher energy consumption and increased utility bills.
If you notice any of these symptoms, it's essential to have a professional HVAC technician inspect and diagnose the issue to determine if the blower motor needs to be repaired or replaced.
Consequences of a Failing Blower Motor
When the blower motor fails, it can have several consequences for your HVAC system and your home's comfort:
- Inability to heat or cool your home effectively: Without a functioning blower motor, the HVAC system cannot circulate the conditioned air, making it difficult to maintain the desired temperature in your living space.
- Potential damage to other HVAC components: A failing blower motor can put additional strain on other components, such as the compressor or heat exchanger, potentially leading to further system failures.
- Reduced indoor air quality: Poor air circulation can lead to the buildup of pollutants, allergens, and humidity, negatively impacting the indoor air quality in your home.
- Increased risk of system failure: If the blower motor is not repaired or replaced, the continued strain on the HVAC system can ultimately lead to a complete system failure, requiring a more costly replacement.
Addressing a failing blower motor promptly is crucial to maintaining the efficiency and longevity of your HVAC system, as well as ensuring the comfort and indoor air quality of your home.
Can I drive my car with a bad blower motor?
Cost of Repair: While it may not be urgent, it's advisable to get it repaired soon to avoid more extensive repairs down the line. In summary, while it is safe to drive with a failing blower motor resistor, addressing the issue promptly can help maintain comfort and prevent further complications.
What happens when the blower motor goes out in a car?
The blower motor is what ``blows'' the air through the vents. If it is bad; it will not come on at all, the wind speed coming out of the vents will be very low, or the motor may be very loud and noisy. It could be a combination of all theses things.
How do you know if your blower motor is bad?
A failing blower motor may emit unusual sounds. This may sound like screeching or squealing if it has bad bearings. You may hear a rattle or a banging sound if something inside the motor has broken or come loose.
Can I run my car without a blower motor?
Your car's HVAC blower motor is not only necessary for the operation of your air conditioner. Without a functioning blower motor your engine runs the risk of overheating.

How do I know if I need to replace my blower motor?
You should replace your blower motor when you notice the following signs:
- Weak Airflow. The first indication that you have a faulty blower motor is when the airflow out of your air conditioner is weak.
- No Airflow.
- Unusually High Energy Bills.
- Strange Sounds.
- Overheating.
What happens if a blower motor fails?
An Overheating HVAC System
If your blower motor starts to go out, it can cause the rest of the system to overwork and heat up.
How much does it cost to replace a blower motor?
Replacing a furnace blower motor costs $560, on average. Depending on the size and type of motor, most people pay $300 to $900. The average blower motor replacement cost is $560, but the final price depends on labor fees, as well as the cost of the parts.
Is it expensive to replace a blower motor?
The average blower motor replacement cost is $560, but the final price depends on labor fees, as well as the cost of the parts. Some higher-end models feature large or hard-to-reach motors, which could bring your HVAC blower replacement cost to as much as $2,400.
What causes a blower motor to go bad?
Overheating is one of the most frequent occurrences that can render the blower motor inoperative. If the motor has overheated, it may shut itself down to prevent damage. You should keep your HVAC clean and clear of any blockages or debris to avoid overheating and maintain efficiency.
