Abstract: A method for starting a blower motor with a locked rotor condition, the motor having one or more speed settings, each speed setting having a reference voltage and reference current value associated therewith, the method comprising, from a motor off condition, applying the reference voltage to the motor, the reference voltage associated with a desired speed setting; measuring current flowing through the motor to define a measured current value; comparing the measured current value to the reference current value associated with the desired speed setting to determine if a locked rotor condition exists; if a locked rotor condition exists, increasing the motor speed from the desired speed setting until either the output speed is at a maximum speed or the locked rotor condition ceases to exist; and adjusting the motor output speed value to the desired speed setting.
