Cause
Inspection/Remedy/Adjustment
Replacement if a malfunction
1. Malfunction of voltage select
harness ***
For 200V specifications
a. Check if there is a broken wire in the voltage
select harness.
b. Disconnect the connector at the transformer
side, turn on the power and then measure the
voltage at the cord.
(The wiring position may vary depending on
the voltage specifications.)
OK if same as wall outlet voltage
