[P12 error]

Turn off the power.

Are not there connections errors or

disconnection on connectors CN333 and CN334

of indoor unit P.C. board (MCC-1402)?

NO

Remove connectors CN333 and CN334 of indoor unit P.C. board (MCC-1402).

Does the fan rotate without trouble when handling the fan with hands?

YES

YES

NO

Correct connection of connector.

Replace indoor fan motor.

Are resistance values between phases

at fan motor connector CN333 motor side of indoor P.C. board (MCC-1402) correct? *1

YES

Is resistance value of fan motor connector CN333 at motor side of indoor P.C. board (MCC-1402) correct? *2

YES

Is signal output of indoor fan motor

position detection correct? *3

YES

Check indoor P.C. board

(MCC-1402).

Defect → Replace

NO

Replace indoor fan motor.

*1

• Are not coil windings between 1 (Red lead) and 3 (White lead), between 3 (White lead) and 5 (Black lead), between

5(Black lead) and 1 (Red lead) opened or shorted? → For resistance, see the following values.

Approx. 70 to 100Ω	SM56, SM80
35 to 50Ω	SM110, SM140

NO

Replace indoor fan motor.

*2

Check resistance of fan motor position detection circuit.

Is not coil winding between 1 (Yellow lead) and 4 (Pink lead) opened or shorted? → Resistance: Approx. 5 to 20kΩ

NO

Replace indoor fan motor.

*3

Check fan motor position detection signal.

•Using a tester, measure the voltage between CN334 1 and 5 of indoor P.C. board (MCC-1402) under condition that CN333 and CN334 are mounted and the power is turned on.

→Rotate the fan slowly with hands, and check the pin voltage swings between 0 to 5V voltage.

•Between 4 and 5 : 5V
