I bought this LG refrigerator last year Recently I have experienced the refrigerator
is not cooling both top and bottom compartment. Right now, no more warm outside
the fridge. This refrigerator is fix with built in diagnostic capabality. I'm
try open the microcontroller cover and push self diagnose button the result
is:-
1) push first times > all display flashed.
2) push second times > display show number 2.(What does it
mean??) Please provide solution.
DID YOU CHECH THE MOTOR TO SEE IF IT IS RUNNING. THE RESISTANCE OF THE WINDINGS ARE ABOUT 300OHMS IF THE MOTOR IS OK CHECK THE CAPASITOR OR THE FUSE. IF OK CHECK THE THERMOSSTATE AS THEY SOMETIMES GO OPEN IT IS A THERMAL DEVICE.
GOOD HUNTING
If you pull frig out from the wall, so that you can get behind it you will see a diagram with information on it. It states what happens with what test.
TEST1-All display lights come on
TEST2-Number 22 22 appears
TEST3-Number 33 33 appears
I have a question is your frig making a loud humming sound or a screach. If so it means that the fans need replacing.
