6 HOW TO CHECK THE ELECTRIC PARTS

Before repairing, use multimeter to judge circuit stand of fail
Part.
Motor&
The assembly of electric
Filter
capacitor it is mainly used to
start motor and control the
motor rotation direction. And
different capacitance should
suit for different motor, or the
motor would not work
properly

Where, what & how to check?
Check resistance of the motor.
Test point Normal value
Yellow—Light
2.5~4.5Ω

Blue—Light blue 2.5~4.5Ω.
Check capacitance of the capacitor.
Test point Normal value
Indicating needle rises
Yellow-Blue
and immediately
indicates ∞.
The needle is stopped after it is raised.
Means Lack of capacitance of the
capacitor.
The needle doesn't move Means
Capacitor is fully discharged.
