Replacing the Blower Wheel and Capacitor

Primary Keyword(s): Replacing blower wheel; Replacing capacitor

In addition to replacing the blower motor itself, there are two other components that may need attention during the replacement process: the blower wheel and the capacitor. The blower wheel is responsible for moving the air through the HVAC system, while the capacitor provides the motor with an initial electrical charge to start spinning.

Let’s take a closer look at these components and their potential replacement needs. 1.

Replacing the Blower Wheel

Over time, the blower wheel can become worn or damaged, affecting its ability to efficiently move air. If you notice a decrease in airflow or excessive noise coming from your HVAC system, it may be time to replace the blower wheel along with the motor.

The process of replacing the blower wheel is relatively straightforward. It involves removing the blower housing and detaching the wheel from the motor shaft.

In some cases, you may need to use a puller tool to remove a tightly secured blower wheel. Once the old wheel is removed, simply attach the new wheel to the motor shaft, ensuring it is securely fastened.

Finally, reassemble the blower housing and test the newly replaced blower wheel for proper functionality. 2.

Replacing the Capacitor

The capacitor is a small cylindrical device that stores and provides an electrical charge to the blower motor to initiate rotation. If you experience issues such as the motor not starting or a humming sound coming from the HVAC system, it’s possible that the capacitor needs replacement.

To replace the capacitor, start by disconnecting the power supply to the HVAC system. Locate the capacitor, which is typically found near the blower motor.

Take note of the wiring connections and their positions to ensure proper reconnection later. Remove the wires from the terminals on the old capacitor and carefully remove it from its mounting bracket.

Install the new capacitor in the same position, making sure it is securely fastened. Reattach the wires to the corresponding terminals, referring to the notes you made earlier.

Finally, restore power to the HVAC system and test the motor to ensure it starts and operates correctly.

Some New Motors Come with Compatible Capacitors
