6 HOW TO CHECK THE ELECTRIC PARTS
20
Part. Circuit Diagram/Principle Where, what & how to check?
Motor&
Filter
The assembly of electric
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
Check resistance of the motor.
Check capacitance of the capacitor.

Indicating needle rises
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.
