Shutting off the Power to the Fan

To ensure your safety, start by shutting off the power to the fan before proceeding with any maintenance or repairs. Turning off the electricity is crucial to prevent accidental electrocution. Locate the circuit breaker for the fan and flip the corresponding switch to the "off" position. Once the power is successfully cut off, you can begin removing the old belt. This involves accessing the fan unit and locating the motor pulley and the fan pulley. Use a wrench to loosen the bolts or screws that secure the belt in place. Carefully release the tension on the belt and slide it off the pulleys. Take note of the belt’s orientation and any markings for future reference. Once the old belt is removed, you can proceed to the next step of replacing it with a new one.
