compartment heater.
Repair the • The compressor is ON,
contact fail- the damper of the ice mak-
ure. ing compartment is open.
• The compressor is OFF,
Replace.
the damper of the ice mak-
ing compartment is close.
Replace the The control under the
operation assumption that the out-
P.C. board. side temperature is 25 °C
is performed.
Ice making test operation
starts when the freezing
compartment thermistor
reads temperatures of
–10°C or less and the
door keeps closed for
3 hours or more.
Repair the The defrost heater-2 is
contact fail- stopped and if the next
ure. defrosting finishes in
2 hours, the error code
will disappear.
Replace.
Repair the • 3 minutes later, the refrig-
contact fail- erator fan motor is reacti-
ure. vated to be checked.
• Until the fan motor oper-
ates correctly, the alarm
sounds every time the
door is closed.
