Air System
Fan Motors
Both the indoor and outdoor fan motors are DC motors driven by the main board and provide feedback
to the main board for proper speed conrmation.
Indoor Fan Motor
The indoor fan motor turns a blower wheel which is attached to the motor shaft with a 4-mm Allen screw.
The opposite end of the blower wheel inserts into a bearing assembly.
The main board supplies high voltage DC to drive the fan motor and receives speed feedback from the
motor.
The motor is secured with a bracket and two screws.
NOTE: If the blower should disengage the
bearing on the left side, the end cap will have to
be removed and the bearing repositioned on the
shaft.
Indoor Blower Wheel
The indoor blower wheel is attached to the motor shaft with a 4-mm Allen screw. The opposite end of
the blower wheel inserts into a bearing assembly.
