8 TROUBLE SHOOTING GUIDE
CONDITION CHECKPOINT METHOD OF INSPECTION CAUSE / REMEDY
Motor fails to rotate
(no noise is heard at all) Power supply cord Check power supply cord continuity. If there is no continuity, replace the cord reel unit.
Fuse
(Plug for UK only) Check plug fuse continuity. If there is no continuity, replace the cord reel unit.
Fuse of P.C.B. Ass’y
(250V, 12 A) Check fuse continuity. If there is no continuity, replace
P.C.B. Ass’y.
Motor continuity Check motor continuity between
carbon brush holder tabs. If there is no continuity, replace the carbon brush or motor.
Check the motor performance. Apply a voltage directly to both
sides of the motor terminal to see if
the motor performs as specified.
If the motor fails to perform,
replace it with new one.
ON/OFF Switch Check continuity across switch
connections If there is no continuity, replace Switch or P.C.B. Ass’y.
Triac (Inside of P.C.B.) Check if the triac is in open circuit. If it is in open circuit, replace
P.C.B.Ass’y.
P.C.B. Ass’y Check the internal parts for
anything unusual. (burn-out, melt-
down, etc.)
If anything is found unusual,
replace the P.C.B. assembly with
new one.
Motor runs but there is no suction Hose or Suction inlet Check if there is any blockage in
the hose or suction inlet. If there is any blockage, remove it.
Dust compartment / Filters Check if dust compartment is full
or there is dust accumulated in the
filters.
If dust compartment is full, empty
it.If the filters are dirt of dust,
clean them out or replace.
Noise or vibration Motor fan Check dust accumulated in motor
fan (it could happen if the vacuum
cleaner has been used without
central filter).
If there is dust accumulated in the
motor fan, replace the motor and
check filter condition. (never try to
dismantle the motor fan)
Motor does not change power
(runs always at full speed) Control Axis Check if the potentiometer is short-circuited. If it is short-circuited, replace power control circuit.
P.C.B. Ass’y Check if power control circuit is
short-circuited. If it is short-circuited, replace it.
Motor runs irregularly control Axis Check possible bad contact of
P.C.B. Ass’y. If there is bad contact, replace P.C.B. Ass’y.
