The voltage should be within the range of
4.5V~1.0V between MAIN PCB CN30 #3
and #9.
The voltage should be within the range of
4.5V~1.0V between MAIN PCB CN30 #7
and #9.
The voltage should be within the range of
4.5V~1.0V between MAIN PCB CN30 #4
and #9.
The voltage should be within the range of
4.5V~1.0V between MAIN PCB CN30 #10
and #9.
The voltage should be within the range of
4.5V~1.0V between MAIN PCB CN30 #11
and #12.
The voltage should be within the range of
4.5V~1.0V between MAIN PCB CN51
#13 and #14.
The voltage should be within the range of
4.5V~1.0V between MAIN PCB CN90 #3
and #4.
The voltage should be 7V~12V between
MAIN PCB CN74 GRAY and BLUE.
The voltage should be 7V~12V between
MAIN PCB CN74 GRAY and GREEN.
The voltage should be 7V~12V between
MAIN PCB CN74 GRAY and YELLOW.
Disconnect MAIN PCB CN70 from PCB, and
read the resistance between Orange and Brown
wire terminals (Refer to the Wire Diagram for the
resistance value). 0 Ohm Heater Short
Ohm Wire Cut or Blown Thermistor
Disconnect MAIN PCB CN70 from PCB, and
read the resistance between Orange and White
wire terminals (Refer to the Wire Diagram for
the resistance value). 0 Ohm Heater Short
Ohm Wire Cut or Blown Thermistor
After replacing Ice-Maker, plug in the unit
and check its operation.
Disconnect MAIN PCB CN73 from PCB, and
read the resistance between Black and Brown
wire terminals (Refer to the Wire Diagram for
the resistance value). 0 Ohm
Heater Short
Ohm Wire Cut or Slipped-out Terminal
It needs a Oscilloscope to do the error check.
So, it is more realistic checking the error after
replacing Main or Panel PCB.
