How to do Self-Diagnosis
The voltage should be within the range
of 4.5V~1.0V between MAIN PCB
CN40 #5 and #8.
The voltage should be within the range
of 4.5V~1.0V between MAIN PCB
CN40 #9 and #8.
The voltage should be within the range
of 4.5V~1.0V between MAIN PCB
CN40 #6 and #8.
The voltage should be within the range
of 4.5V~1.0V between MAIN PCB
CN40 #11 and #8.
The voltage should be within the range
of 4.5V~1.0V between MAIN PCB
CN40 #2 and #1.
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 #8.
The voltage should be within
the range of 4.5V~1.0V between
MAIN PCB CN40 #10 and #8.
The voltage should be 7V~12V between
MAIN PCB CN75 GRAY and YELLOW.
The voltage should be 7V~12V between
MAIN PCB CN75 GRAY and ORANGE.
The voltage should be 7V~12V between
MAIN PCB CN75 GRAY and SKYBLUE.
Disconnect MAIN PCB CN70, CN71 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, CN71 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 CN76 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.
