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 “YELLOW” 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
be observed at early stage after such shock.But it may be found later,This type of
mishandling void our warranty.
