Test in resistance.
TOOL: Multimeter.
Test the resistance of the main winding. The indoor fan motor is fault if the
resistance of main winding 0(short circuit)or
∞（
open circuit
）
.
Test in voltage
TOOL: Multimeter.
Insert screwdriver into to rotate indoor fan motor slowly for 1 revolution or
over,and measure voltage “BLACK” and “GND” on motor. The voltage repeat 0V
DC and 5V DC.
Notes:
1) Please don’t hold motor by lead wires.
2) Please don’t plug IN/OUT the motor connector while power ON.
3) Please don’t drop .Hurl or dump motor against hard material.Malfunction may not
