contact failure.
• When S-compartment
is used as “freezer”:
S-damper is open when
compressor is turned
on, S-damper is closed
when compressor is
turned off.
• When S-compartment
is used as other than
“freezer”: S-damper
remains open for the
first 3 minutes and then
closed for the rest of
time.
S-compartment: Versa
(select) compartment.
2. Check the resistance of thermistor.
Replace.
E 16
Trouble of veg-
etable compart-
ment thermistor
When there is a short
or open circuit in the
vegetable compartment
thermistor .
1. Connector CN9S on control board, 2-pin
wire to wire connector
Repair the
contact fail-
ure.
• When R-damper is open,
V-heater is turned on.
• When R-damper is
closed, V-heater is
turned off.
2. Check the resistance of thermistor.
Replace.
E 17
Trouble of ice
making com-
partment
thermistor
When there is a short
or open circuit in the ice
making compartment
thermistor.
1. Connector CN9S on control board, 6-pin
wire to wire connector
Repair the
contact fail-
ure.
• When ice making com-
partment is used as
“refrigerator”, synchronize
I-damper with R-damper.
• When ice making com-
partment is used as “ice
making”, synchronize
I-damper with F-damper.
2. Check the resistance of thermistor.
Replace.
E 18
Trouble of
outside air
thermistor
When there is a short or
open circuit in the out-
side air thermistor.
Replace the
operation
P.C. board.
Compressor is activated
at “Speed-level 2.”
E 23
Trouble of
thermopile
When there is a short or
open circuit in the out-
side air thermistor.
Relay connector 10 pin 2 positions.
Refer to "5-9.3 Failure diagnosis for the
thermopile (HIKARI i-see Sensor)".
Perform supercool freez-
ing control in emergency
operation mode.
E 30
Trouble of
defrost heater 1
(*6)
When defrosting is not
finished in 2 hours.
1. Connector CN2A on control board,
Defrost heater plug and receptacle,
1-pin wire to wire connector,
Thermal fuse 4-pin wire to wire connec-
tor
Repair the
contact fail-
ure.
The defrost heater is
stopped and if the next
defrosting finishes in 2
hours, the error code will
disappear.
2. Check the resistance of defrost heater. Replace.
3. Check the continuity of thermal fuse.
Replace.
E 31
Trouble of
refrigerator
fan motor
• When motor doesn’
t rotate even though
power is on.
• When the waveform,
which indicates the
rotation times of motor,
cannot be detected.
1. Connector CN5D on control board,
Refrigerator fan motor 4-pin wire to wire
connector
Repair the
contact fail-
ure.
• 3 minutes later, the refrig-
erator fan motor is reacti-
vated to be checked.
• Until the fan motor gets
to operate correctly, the
buzzer sounds every
time the door is closed.
2. Check refrigerator fan motor operation. Replace.
E 32
Trouble of box
fan
• When motor doesn’
t rotate even though
power is on.
• When the waveform,
which indicates the
rotation times of motor,
cannot be detected.
1. Connector CN4D, CN5D on control
board, Box fan, 4-pin wire to wire con-
nector
Repair the
contact fail-
ure.
• 3 minutes later, the box
fan is reactivated to be
checked.
• Until the fan motor gets
to operate correctly, the
buzzer sounds every
time the door is closed.

gear box is reactivated to
be checked again.
2. Ice gear box frozen point
Replace.
3. Check the trouble of the ice gear box
with the ice making test operation.
Replace.
E 34
Clogging of
refrigerant
pipe or trou-
ble related to
compressor
