2. • • If power is getting to the blower motor, but the motor does not run, the motor may be burned out. If the blower motor is burned out, replace it. If the blower motor hums, check the blower fan to ensure that it spins freely. If the blower fan is unobstructed but does not spin freely, replace the blower motor.

   Why is my furnace blower motor not turning on?

   • So, even if your furnace hooks up to a 240-volt outlet, it will still need a capacitor to store and discharge the 400+ volts it needs to run. If your furnace blower motor won’t turn on, the source of the issue may be a damaged capacitor. Once a load becomes too large, a capacitor can break and negatively impact the performance of your furnace.

   Why does the blower motor turn on?

   • If the blower motor turns on, this indicates that the problem is not with the control board or the unit. The issue is with the thermostat wire (if you've already troubleshot the thermostat itself and determined it is not the problem). The problem may be due to a clog in, or a collapse of, the ductwork (see photo below).

   Can a faulty thermostat cause a furnace blower to not work?

   • Yes, a faulty thermostat can indeed cause your furnace blower not to work properly. The thermostat serves as the communication hub between your heating system and your desired temperature settings. If the thermostat malfunctions or is incorrectly calibrated, it can send inaccurate signals to the furnace blower motor, leading to improper operation.

   Why is my furnace blower making a squealing noise?

   • When troubleshooting furnace blower motor problems, common issues may include inadequate airflow, strange noises (such as grinding or squealing), or complete failure of the fan to operate. One possible cause could be a dirty air filter restricting airflow or causing strain on the motor.

   Why does my blower fan run if heating is off?

   • Sometimes the blower may run even with heating off. However, most people set the fan to AUTO for convenience. In this case, the fan will only run when heating is ongoing and go off when heating stops – even when the furnace is still switched on. So, it means that your blower fan is off because the heating is off.

   • It’s a Thermostat Setting Issue. Most thermostat issues originate at the thermostat, and blower motor issues aren’t different. If your blower isn’t turning, you most likely have a faulty thermostat.
   • The Thermostat is Faulty. Still, on the thermostat, you may also want to diagnose it for internal damage. If the thermostat is broken, the furnace may not work.
   • The Fan isn’t Getting Power. Hopefully, you’ve confirmed that the rest of the furnace has power. You’ll know you have power if the burners light up when you turn on the furnace.
   • The Blower Motor Capacitor is Defective. We’ve mentioned that the blower motor gets starting power from a special capacitor. These capacitors are fairly powerful, typically ranging from 200V to 450V.

   • Check The Fan Belt

   The next thing that you should do if your furnace’s blower isn’t turning on is to check the circuit breaker. The furnace’s circuit breaker is a safety device that protects your equipment and wiring from excessive electrical currents. If your furnace’s circuit breaker trips, go ahead and reset it and see if it runs again. Keep an eye on your furnace...

   The motor overload is a device that protects the motor from burning out. For example, if the blower motor gets stuck, it will start heating up and the motor overload will trip. When the motor overload trips, power is disconnected from the motor. This helps prevent the motor from burning out or starting a fire. Most blower motors have a motor overlo...

   If you have a PSC (permanent split capacitor) motor, then you should check its capacitor. The capacitor is needed for the blower motor to start up. Without a capacitor, a PSC blower motor won’t turn on. The capacitor also helps smooth out the rotation of the blower motor once it’s started up. How do you know if you have a PSC blower motor? The easi...

   Some furnaces (especially older ones) have belt-driven blowers. If the fan belt snaps, your blower motor will spin, but the fan won’t. So what causes a fan belt to snap? It’s all due to wear and tear. Even properly installed fan belts eventually wear out, so they are replaceable. But if your fan belt prematurely wears out, then it’s most likely out...

   • Inspect the Wires in Your Furnace. Make sure that the power cord hasn’t melted or a fuse hasn’t been blown. If your cables are looking fine, try unplugging the fan for a few minutes and then plugging it back in again.
   • Make Sure Your Thermostat Is Set and Working Correctly. If your blower fan has power, then the next step is to check the thermostat on your furnace. Most thermostats will be set to “auto” automatically when they come from the factory.
   • Check the Filters and the Vents. Blower motors are designed to circulate air, so they won’t work if there’s no air to move. You should always check the filters and vents surrounding the blower to make sure that the blower isn’t having a hard time working.
   • Check Your Furnace Blower’s Drive Belt. To figure out if the blower motor belt is damaged, turn off the furnace at the circuit breaker panel in your home.
