Notes (1) See pages 62 for the DC fan motor and indoor unit circuit
board check procedure.
(2) After making sure the DC fan motor and indoor unit circuit
board are normal, connect the connectors and confirm that
the fan motor is turning.
(If power is turned on while one or the other is broken down,
it could cause the other to break down also.)
* Disconnect the fan motor
connector, then investigate
the DC fan motor and indoor
