Remark
：
1) 9000 BTU, 230 VAC both Cool Only and Heat Pump models: Measure the black pin and red pin of the motor
connector, the resistance should be around 385Ω at 20
℃
(68
℉
)
2) 9000 BTU and 12000 BTU, 115 VAC both Cool Only and Heat Pump models: Measure the black pin and red pin
of the motor connector, the resistance should be around 50Ω at 20
℃
(68
℉
)
3) 12000 BTU, 230 VAC both Cool Only and Heat Pump models: Measure the black pin and red pin of the motor
connector, the resistance should be around 293Ω at 20
℃
(68
℉
)
4) 18000 BTU, 230 VAC both Cool Only and Heat Pump models: Measure the black pin and red pin of the motor
connector, the resistance should be around 84.5Ω at 20
℃
(68
℉
)
5) 24000 BTU, 230 VAC both Cool Only and Heat Pump models: Measure the black pin and red pin of the motor
connector, the resistance should be around 88.5Ω at 20 ℃ (68 ℉ )
