Measure the resistance between any of
the two connectors

1. Test the duct set (motor included) to judge if the motor is open-circuit.
NOTICE: Judge if there is any burning smell of the motor before having diagnosis. If
yes, the motor is burned. Replace it. Otherwise, go on below detection.
a) Set the Multimeter function to “Resistance
measuring” .
b) Measure the resistance between any of the
two connectors.
c) If any of the measurements is infinite, means
the circuit between the two connectors is open
circuit, the motor is damaged. Replace with a
new motor.
d) If the motor is shorted inside, Multimeter is
not applicable for detection. Directly test with a
new motor after disconnecting the connectors.
