When it comes to furnace motors, the average lifespan is around 10 to 15 years. However, there are a few factors that can influence this, such as the size of your house, the type of furnace model you have, how often you use it, and how well it is maintained.
Factors such as how often you use your furnace and the type of environment it is in will affect how long the motor will last. For instance, if you live in an area with extreme temperatures, then your furnace motor may need to work harder and faster, leading to a shorter lifespan.
On the other hand, if you live in an area with moderate temperatures and you use your furnace only occasionally, then the motor should last longer. Additionally, proper maintenance can help extend the life of your furnace motor.
Regularly checking your furnace and changing the filters will ensure that it operates as efficiently as possible.
Overall, if your furnace is well maintained, it can last for 10-15 years. However, if you neglect it or use it frequently in high temperatures, you may find that it wears out sooner.

What causes a furnace motor to burn out?
A furnace motor can burn out if it is not maintained properly or experiences too much wear and tear. Inadequate lubrication, accumulation of dirt and dust, and exposure to extreme temperatures can cause unnecessary strain on the motor and eventually lead to burning it out.
Failing to replace worn bearings and failing to clean the air filter can also cause the motor to burn out. Additionally, a furnace motor can burn out when its amp rating is too low — this happens when the wrong size motor is installed or when the motor does not receive enough power due to old or inefficient wiring.
In any case, it is important to check for causes of motor burnout and take preventive maintenance steps to avoid such situations.
When should a furnace blower motor be replaced?
Replacing a furnace blower motor depends on various factors, such as how old the furnace is, how much use it gets, and how well it has been maintained over the years. Generally, it is best to replace the blower motor when the furnace is more than 10 years old, when it is subject to regular, heavy use, and when it has not been maintained regularly.
If the furnace is older than 10 years and is experiencing erratic operation, noises, or strange smells, then it would be wise to replace the blower motor. Additionally, due to the extreme heat generated by furnaces, these components are vulnerable and often deteriorate if not regularly inspected and maintained over time.
Signs that a furnace blower motor needs to be replaced include abnormally loud or strange noises coming from the motor, burning sounds, a humming sound after the blower has stopped running, and the motor housing often appearing hot to the touch.
If any of these symptoms are present, then a furnace blower motor should be replaced as soon as possible to ensure the safety, reliability, and efficiency of the furnace.

What are the signs of a blower motor going out?
The signs of a blower motor going out can vary, but they usually involve a decrease in the amount of airflow, strange noises coming from the heater, or an inability to increase or decrease the speed of the blower.
In electric powered motors, there can also be specific signs of wear such as diminished power, sparking, smoking, or burning smells. As the motor fails, it will become increasingly difficult for the blower fan to blow air through the system, resulting in a decrease in airflow and a decrease in air temperature.
It is also common for the motor to start making strange noises such as buzzing, grinding, or squealing, before it completely fails. If you notice any of these signs, it is important to have the motor repaired or replaced as soon as possible to avoid further damage to the system.
How can I tell if my furnace blower motor is bad?
The best way to tell if your furnace blower motor is bad is to first check the power supply to the furnace. Make sure that the power supply, as well as any circuit breakers, are in proper working condition and are not tripped.
If the power supply and circuit breakers appear to be functioning properly, then the next step would be to inspect the blower motor itself. Look for any signs of damage on the motor or in the wiring that connects the motor to the furnace.
If there are any damaged components, then you can determine that the blower motor is likely bad and needs to be replaced. You should also listen to the motor when it is running, as a bad motor may make unusual or loud noises compared to a motor that is working properly.
If the motor is still running, but the fan that is connected to the furnace is not spinning, then the motor may still be defective. Finally, if you have a multimeter, you can use it to test the motor for continuity to ensure it is functioning correctly.
If any of the steps above have indicated that the blower motor is bad, then it should be replaced as soon as possible for the furnace to continue to work properly and safely.
How do I know if I need to replace the blower motor or the resistor?
If you’re not sure whether you need to replace the blower motor or the resistor, there are a few steps you can take to help you decide. First, check your owner’s manual to see if it explains the location of the blower motor and resistor in your car’s model.
Secondly, inspect the blower motor and resistor to see if either one appears to have damage or corrosion. If the blower motor looks undamaged and the resistor looks corroded or burnt, it suggests the resistor is what needs to be replaced.
However, if the blower motor shows damage or corrosion, it may indicate that it is the part that needs replacing. Additionally, you can look up tutorials online to address these issues specific to your make and model of car.
If you’re still not sure, it’s best to take your car to a qualified mechanic for diagnosis.
How much does it cost to change the blower motor and resistor?

Should you replace blower motor and resistor at the same time?
It depends on the age and condition of the current blower motor and resistor. If both components are relatively new and in good condition, it may not be necessary to replace both components. Generally speaking, if the blower motor or resistor has failed or is experiencing any other issues, then it is recommended that both components be replaced at the same time as this will help ensure that the new parts work in conjunction with one another.
Additionally, if only one component is replaced, then it is possible that the new component will be subjected to further stress due to the failure of the old component. Therefore, if you are unsure of the age and condition of both components, it is best to replace them both at the same time.
What causes blower motor resistor to fail?
A blower motor resistor typically fails due to the electrical contacts becoming corroded, the electrical current becoming too high, or the resistor itself becoming worn out from constant use. Corrosion commonly occurs due to contact with water or other environmental factors, and can occur inside the resistor or on its external terminals.
Over time, the corrosion can form a barrier preventing electrical current from passing through, causing the motor to fail.
Too much electrical current can put a strain on the blower motor resistor, which can cause it to fail over time. The electrical current is typically determined by the system’s electrical configuration, and if it’s too high, it can cause an excessive amount of heat to build up in the resistor, causing it to fail.
Finally, a worn-out blower motor resistor can fail due to constant use, especially if the maximum power rating of the resistor is exceeded. The constant use can cause the resistor’s connecting wires to become strained and eventually break, or the resistor’s insulation to become worn down, causing it to short out and fail.
