CN301

CN300

*Connector of RAV-SM560AT-E differs from that of RAV-SM800AT-E.

CN300: Motor coil winding

CN301: Motor position detection

Normal fan motor

(Control or CDB P.C. board)

(Control P.C. board or CDB P.C. board)

NOTE :

Defective fan motor

However, GND circuit error inside of the motor is rarely detected even if the above check is carried out. When the circuit does not become normal even if P.C. board has been replaced, replace outdoor fan motor.
