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

∞ Ohm, check
if the Wire/Thermal Fuse or the

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-circ
uited). 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-
circuite d). 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 Vo
ltage is too l
ow.
Check the input voltage. (This error
occurs when the input voltage is AC
106 V or lower.)
Check the input voltage. (This error
