Customer Question

I have a lg SxS refrigerator about 10 yrs old. After changing the water filter, it just stopped running. The manual troubleshooting, as one solution, suggests refrigerator control is off, and to see setting the controls. There is no other reference in manual as to how to set controls. Any suggestions?

Do you have a model number so I can better assist you? It should be located on a sticker near the ceiling of the refrigerator section.

Also what do you mean by "just stopped running"? Is the refrigerator and freezer section not cooling? Do the lights inside some on when you open the door? Is the unit 100% silent? And how long has it been this way?

Model no. LSC26905 . Neither refrigerator or freezer are cooling. No lights, yes 100 percent silent. Happened late yesterday afternoon.

OK unfortunately only 1 thing can cause that if you're sure the refrigerator is getting power from your house---your main control board on the back of the unit has failed and would need to be replaced. Turning the unit off would still leave the lights working like normal. You'll need the last 2 letters of your model (which are missing from your partial model) to make sure you order the correct board, but below is a link to the board that is usually needed for your model.

Why would this happen?
Expert:  Tyler Z. replied 1 year ago.

It can happen from power fluctuations from your house but honestly it's probably from nothing at all other than poor manufacturing. Any technician that works on LG refrigerators has seen his/her fair share of these boards going out. I personally have seen hundreds that fail in this exact same way---just not a robust part.
