Is the terminal voltage 110 V AC across the terminals
and in the CN1A connector on the control board?
Inspect power-supply wiring such as power cord and
breaker.

Is the refrigerator in the demonstration mode?
Release the demonstration mode. (See page 9.)
No
Dip the freezer compartment thermistor into ice water (0°C),
and disconnect the 6-pin connector in the connector cover in
the back of the ice making compartment, and measure the
resistance between the terminals (white) and (white).

Replace the compressor.
Replace the lead
wire assembly (lead

Abnormal
Normal
Detach connector CN50G on control
board and check the resistance between
each of the following terminals.

Check the error display of self-
check after turning off and on the
power supply.
With all the connectors connected.
Inverter-related parts may have a
trouble. Conduct the ice making
test operation to check the error
code. (See pages 34, 35 for error
codes.)
