<Only for 4-way air discharge cassette type models (RAV-SM560UT-E/RAV-SM800UT-E)>

Turn off the power.


Are not there connections errors or		YES
disconnection on connectors CN333 and CN334
of indoor unit P.C. board (MCC-1402)?
	NO
	NO

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

Does the fan rotate without trouble		NO
Does the fan rotate without trouble
when handling the fan with hands?
	YES
	YES

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. AIU-P401H/HR, P451, P501, P561, P631, P711, P801 Approx. 70 to 100

AIU-P1121H/HR, P1401, P1601 Approx. 35 to 50

•Is not earthed between cabinet and 1, 3, 5 10M or more

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 20k

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	CN333
