6-3-3 When the Indoor unit fan motor doesn't operate
1. Check if power(AC220V) is being supplied.
2. Check if the operating condenser(CR71, CR72) and connector(CN73, CN74) are properly assembled.
3. Put the fan in operation with the remote control and check if the fan is rotating after the auto grille is full open.
(If so, it is in norma operation)
4. If not, measure AC voltage of No. 5 and 3 of CN73, CN74.
• If the voltage value is 180~220V : Poor motor
• If not : Poor PCB
