COMPONENTS TESTING
Fan Motor
Resistance Test.
Test the resistance of the main winding. The indoor fan motor is faulted if the resistance of
main winding 0 (short circuit)or ∞ open circuit.
DC Voltage test
Manually rotate indoor fan motor slowly for several revolutions, and measure voltage “YELLOW” and “GND” on motor. The
voltage repeats 0V DC and 5V DC.
Notes:
• Do not hold motor by lead wires.
• Do not connect or disconnect the molex connecter while power ON.
• Do not drop motor against hard material. Malfunction may not be observed at early stage after such shock. But it may be
found later, this type of mishandling voids our warranty.
