Abstract
A method of evaluating damper operation for a heating, ventilation and air conditioning (HVAC) system includes moving a plurality of dampers of the HVAC system collectively to a baseline damper position. The plurality of dampers is positioned at a flowpath including a fan driven by a motor. The fan is operating by switching the motor on and a baseline output level at the motor is measured. A first damper of the plurality of dampers is commanded to move from the baseline damper position to a first damper position and a first output level at the motor is measured. The first output level is compared to the baseline output level. A difference is indicative of successful movement of the first damper from the baseline damper position to the first damper position.
