Turn off the power.

Is there no connection error or

disconnection on connectors CN333 YES and CN334 of indoor unit P.C. board

(MCC-1570)?

Correct connection

of connector.

NO

Remove connectors CN333

and CN334 of indoor unit P.C. board

(MCC-1570).

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

YES

Are resistance values

between phases at fan motor connector CN333 motor side of indoor P.C. board (MCC-1570) correct? ∗1

NO

Incorrect

CN333

CN334

Replace indoor fan motor.

Replace indoor fan motor.

Correct

∗1

•Are not coil windings between c (Red lead) and e (White lead), between e (White lead) and g (Black lead),

g (Black lead) and c (Red lead) opened or shorted?

→ The resistance should be the resistance value below.between

SM56, SM80 → Approx. 70 to 100Ω SM110, SM140 → Approx. 27 to 40Ω

• Is not grounded between cabinet and c, e, g. → It should be 10MΩ or more.

Is resistance value of

fan motor connector CN334 motor side Incorrect of indoor P.C. board

(MCC-1570) correct? ∗2

Replace indoor fan motor.

Correct

∗2

Resistance value confirmation of the fan motor position detection circuit

Is not status between c (Yellow lead) and d (Pink lead) opened or shorted?

→The resistance should be approx. 5k to 20kΩ.

Is output of	NO
indoor fan motor position
indoor fan motor position
detection signal correct? ∗3

Replace indoor fan motor.

YES

∗3

Confirmation of the fan motor position detection signal

•Using a voltage tester, measure voltage between CN334 c and e on the indoor P.C. board

(MCC-1570) under condition that CN333 and CN334 are mounted and the power supply is turned on. → When rotating the fan slowly with hands, the pin voltage should shake between 0 and 5V.

•Between d and e: 5V

Check indoor P.C. board

(MCC-1570).

Defect → Replace
