CN333 Remove connectors CN333 and CN334 of indoor unit P.C. board (MCC-1570). CN334 Does the fan rotate without trouble when handling the fan with hands? YES NO Replace indoor fan motor. Are resistance values between phases at fan motor connector CN333 motor side of indoor P.C. board (MCC-1570) correct? ∗1 Incorrect Replace indoor fan motor. Correct ∗1 • Are not coil windings between between ƒ (White lead) and … (Black lead), (Red lead) and ƒ (White lead), between … (Black lead) and (Red lead) opened or shorted? → The resistance should be the resistance value below. SM40, SM45 → Approx. 70 to 100Ω • Is not grounded between cabinet and , ƒ, …. → It should be 10MΩ or more. Is resistance value of fan motor connector CN334 motor side of indoor P.C. board (MCC-1570) correct? ∗2 Incorrect Replace indoor fan motor. Correct ∗2 Resistance value confirmation of the fan motor position detection circuit Is not status between (Yellow lead) and ‚ (Pink lead) opened or shorted? → The resistance should be approx. 5k to 20kΩ. Is output of indoor fan motor position detection signal correct? ∗3 NO Replace indoor fan motor. YES ∗3 Confirmation of the fan motor position detection signal • Using a voltage tester, measure voltage between CN334 and ƒ 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 ‚ and ƒ: 5V Check indoor P.C. board (MCC-1570). Defect → Replace – 132 –
