What is an HVAC Actuator?

To sum it up, actuators are the main driving source behind the control of the dampers in an HVAC system. They are motorized units that are responsible for regulating the airflow of smoke and fresh air throughout the system accurately. With low voltage, these components can efficiently and accurately adjust to meet the unit’s needs.

How Do You Test an Actuator?

When testing an actuator, grab a multimeter and connect it to one of the leads. Monitor the amperage reading as the rod extends and retracts. Repeat this cycle to get the most precise measurement of the actuator’s current draw.

Is There a Way to Reset an HVAC Actuator?

This process will differ depending on the brand and actuator type. For blend door actuators, simply remove the actuator and turn the climate control to max heat. Then, turn the blend door shaft until you can feel the max heat coming out of the vents. Finally, reinstall the actuator and once everything is back in place, it should be reset.

What are the Symptoms of a Failing HVAC Actuator?

A faulty or malfunctioning actuator in an HVAC system can manifest through many signs. The most common issues include tapping, knocking and erratic airflow. If you’re experiencing a reduction in airflow or abnormal fluctuations, it could indicate a potential issue with the HVAC actuator.
