check: Is there a short cir-
cuit, open circuit or dam-
age? (See
284
page for the
check procedure.)
DC Reactor continuity
Check: 50 m or higher,
less than 100 m
Ω
.
Fuse check: There should be continuity.
If faulty, replace the control PCB.
Noise filter check:
There should be continuity.
There should be no shorts between phases.
LED1 (Red) check
Light continuously :
Keeps flashing :
1~3 time flash :
Normal
EEV
(Refer to page

)
Power supply check
Measure the power supply at L.N.
(It is normal if it is AC 220/240V.)
Fuse Check: There should be
continuity.
