Is resistance value at motor side of

fan motor connector CN334 on indoor P.C. board

(MCC-1402) correct?

Is resistance value between each phase

at motor side of fan motor connector CN333 on

indoor P.C. board (MCC-1402) correct?

Is there connection error or

disconnection on connector CN333, CN334

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

Is output of indoor fan motor position

detective signal correct?

Does fan turn without trouble

when turning it with hands?

Remove connectors CN333 and CN334

on indoor P.C. board (MCC-1402).

Check insulation resistance value of fan motor position detective circuit.
• Is winding 1 (Yellow lead) to 4 (Pink lead) opened/shorted?

Resistance should be 5k

to 20k

Check fan motor position detective signal.

• Measure voltage with tester between CN334 1 and 5 on indoor P.C. board (MCC-1402)

under condition of CN333 and CN334 installed and power-ON.

Turn fan slowly with hands so that pin voltage

fluctuates between 0 and 5V.

• Between 4 and 5: 5V

• Is not winding 1 (Red lead) to 3 (White lead), 3 (White lead) to 5 (Black lead),

5 (Black lead) to 1 (Red lead) opened/shorted? Resistance value should satisfy the follows.

[4-way Air Discharge Cassette, Compact 4-way Air Discharge Cassette type]
MMU-AP0091H to AP0301H, MMU-AP0071MH to AP0181MH : Approx. 70

• Check insulation resistance between the cabinet and 1, 3, 5 : Should be 10 M

or more.

Detectable only in models with DC fan motor
4-way Air Discharge Cassette, or Concealed Duct Standard type
Under Ceiling, or High Wall type

Replace indoor fan motor.
