[ Freezer Defrost Heater ]
Connector Slipped-Out or Open-
Contact, Wire Cut or Short-Circuited,
Defective Thermistor
Freezer Defrost When the defrosting
does not complete even after it does
defrosting for more than 120 minutes.
Remove the MAIN PCB CN70 and CN77
connectors from the MAIN PCB and
read the continuity between BROWN ↔
ORG wires.
(It differs according to the
energy
consumption.)
When it reads
0 Ohm, check the
Heater
short and when it reads
∞ Ohm, check
if the Wire/Thermal Fuse or the
Bimetal
is Open.

Comp start
failure error
The error code is displayed when the
compressor has failed to start.
Check the soldering status of the
inverter PCB.
(Check if any parts have
short-
circuited). Check if the DC 16V output is
less than 13.5V. Check the Comp
and
Cycle.
Compressor
IPM Fault Error
The error code is displayed when
the compressor IPM fault error has
occurred.
Comp location
detection error
The error code is displayed when the
compressor location detection failed.
Check the compressor wire
connections
. Check
the soldering status
of the inverter PCB. (Check if any
parts
have short-circuited
). Check
the Comp
and Cycle.
Comp motor
constraint error
The error code is displayed when the
compressor motor is constrained.
Check if the compressor and the Cycle is
normal. Check the input voltage.
Check the soldering of the inverter PCB.
(Check if any parts have short-circuited.)
Comp low
voltage
error
The error code is displayed when the AC
Input Voltage is too low.
Check the input voltage. (This error occurs
when the input voltage is AC 106 V or
lower.)
Check the input voltage. (This error occurs
