What to do if your furnace blower is not running?
Listen for the sound of the blower turning on. Check that air is being sucked into the cold-air returns and being blown from the warm-air registers. If air isn’t circulating, check the furnace for a dirty filter or similar obstructions blocking air flow. Clean and service the furnace blower and motor before running it full time.
How can I tell if my blower motor is faulty?
This is usually the first indication that you may have a faulty blower motor. If the airflow coming out of the vents is weak, it can mean that your blower motor is having a hard time pushing enough air through the ducts to achieve your desired temperature.
How does a blower work on an air conditioner?
It takes the cool air created by your air-conditioner and circulates it throughout your indoor space to ensure that the temperature reaches the level dictated by the thermostat. It performs this task by spinning a fan, which causes air to move through the ducts and vents in your home.
Can a furnace blower be used without a furnace burner?
The blower can also be used without the furnace burner’s ignited. To circulate air and clear dust from ductwork, keep the blower in the “on” position. Move furniture or obstacles away from the warm-air supply register and the cold-air return. Locate the household thermostat. Look for the fan and heat/cool switches.
Why is my blower motor not coming on?
With the back wire hooked up I ran a jumper directly to the battery pos and attached it the purple wire terminal on the motor. The motor did not come on. So either my motor is dead shorted or something has gummed up the brushes or they are worn out.

Why does my oil furnace not have a fan?
Mostly “low-boy” oil furnaces, especially older models. Sometimes the belts wear out, crack, and eventually break. If you take a look at the blower section of your heating system it is quite easy to see if you have a belt driven blower motor.
Why is my air conditioner fan not running?
They usually stick open, never sending the signal to the motor. This is much easier and less expensive to repair than a motor going bad. A weak, faulty, or shorted capacitor can prevent the motor from running. And of course, the motor itself can always go bad. Sometimes the bearings seize.
