Abstract
A method for determining proper rotation direction of a reversible motor comprises the steps of: operating the motor to rotate a fan in a first direction, monitoring an operating parameter of the motor while the fan is rotated in the first direction, determining if the monitored operating parameter is within an acceptable range, determining that the first direction of rotation is not the proper rotation direction where the monitored operating parameter is not within the acceptable range, and operating the motor to rotate the fan in a second direction if the monitored operating parameter is not within the acceptable range.
