Resetting the blower on a furnace requires you to go through several steps. First, you will need to turn off the power to the furnace by either unplugging it or turning off the corresponding circuit breaker.
Once the power is off, locate the blower access panel and remove it. Once the panel is removed, locate the blower motor and inspect it. You will need to check the wiring of the motor itself, as well as the electrical connections and the capacitor, if there is one.
If any of these components are damaged, they will need to be replaced before proceeding.
Next, you will need to replace the blower wheel and check the fan belt for any damage. If the belt is frayed, the fan should be replaced. Once the fan belt is secured, carefully tighten the retaining screws for the motor.
This can be done by using a nut driver to gently turn each screw a few turns clockwise.
After the screws have been tightened, you will need to reset the thermostat, which should be done by lowering the temperature of the room setting on the thermostat and waiting for the furnace to cycle on.
Once the motor has engaged, you will need to check the motor again for any noise or vibration. If there is none, the blower has been reset successfully.
How do I reset my furnace motor?
Resetting your furnace motor can be a straightforward process. Depending on your model of furnace, the steps may vary. First and foremost, be sure to turn off the power to your furnace, which you can do at the main circuit breaker box.
