After replacing Direct Drive (DD Icon) motor the fan cuts out after running for a short time
• If you have recently changed a Direct Drive motor and it runs for a short time before stopping:
• Turn on to fan only and watch the motor diagnostic LEDs in the control box.
• If FAN SPEED LED starts to flash a short time after the motor starts.
Most likely, the fan blade has been put in backwards.
• Check that the concave (inner) curve of the centrifugal fan blade is facing the direction of rotation.
Rotation is anticlockwise if viewed from the side where motor cable is on.
• As the blade rotates, the inner concave section of the blade scoops and pushes the air into the dropper.
• If the blade is oriented incorrectly, there is little resistance to rotation, causing the fan to over speed and the fan speed light to flash.
