12-5. Flap Motor Does Not Work

12-5-1. Louver Motor Defective

➀ Set to cooling operation with flap to oscillate (movie) using remote controller and measure voltage applied to

the louver motor at FLAP terminal of 5P connector.

In case of abnormality ➞ Replace indoor unit PCB.

No abnormalities, proceed to check

➁

*Use a circuit tester (set to DC range).

Normal

Color Output Voltage

WHT and each BLU wire DC 1 – 12 V (pulse)

*Use a circuit tester (set to Ω range).

Normal

Color Resistance

WHT and each BLU wire 300 – 450 Ω

➁ Disconnect FLAP of 5P connector for louver motor and measure resistance.

In case of abnormality ➞ Replace louver motor.

No abnormalities, check if there is physical or mechanical interference to louver movement.

12-6. Heating Operation Not Possible

12-6-1. Thermistor 1 Defective

Failure Display on Outdoor Unit PCB: ●● ●● ●●

Check Thermistor 1 (CN15).

➀ Disconnect Thermistor 1 connector (3P, BLK) from outdoor unit PCB, and measure resistance on Thermistor 1

side.

In case of abnormality ➞ Replace Thermistor 1.

Temperature Resistance

Normal

68°F (20°C) 6.0 – 7.1 kΩ

86°F (30°C) 4.0 – 5.0 kΩ

140°F (60°C) 1.5 – 1.7 kΩ

Temperature Resistance

Normal

68°F (20°C) 6.0 – 7.1 kΩ

86°F (30°C) 4.0 – 5.0 kΩ

140°F (60°C) 1.5 – 1.7 kΩ

12-6-2. Thermistor 2 Defective

Failure Display on Outdoor Unit PCB: ●● ● ●● ●●

Check Thermistor 2 (CN16).

➀ Remove Thermistor 2 connector (3P, RED) from the outdoor unit PCB, and measure resistance on the

Thermistor 2 side.

In case of abnormality ➞ Replace Thermistor 2.
