Item Trouble contents
When the Freezer Ice Maker error
occurs more than 3 times, the
error will be displayed.
Display error when open error
is detected by damper heater :

Diagnostic method
After replacing the Ice Maker, check if it
operates normal.
After separating MAIN PCB CN77 wire
from PCB, resistance value between
Black ↔ Brown wire shall be 135 ohm±
7%. 0 ohm : heater short, ∞ Ohm : wire /
bimetal Open.
When measuring the resistance of the
Main PCB CN79 Yellow-Pink wires, it
should be within 102Ω ±7%. 0Ω : heater
short, ∞Ω : Check for Wire Open or
onnector Slip-out
After changing the Ice Maker(R), plug
the refrigerator power code again, and
check the operation.
When measuring the voltage between
the Main PCB CN76-"5" ↔ CN76-"1", it
should read between 7.0V~12V.
