Lights flashing 1-7 and not cooling

I actually have a LG refrigerator with the freezer on the bottom. The display panel inside the fridge is not digital. The panel reads 1-7, warm to coldest. There are 2 adjust buttons on each side and an ice plus button in the center. When it is working properly, the number it is set to will light up green. Right now each number lights up green and moves on to the next number, over and over again and it is not cooling. I've called LG and they don't seem to have current info on this model, it is outdated apparently. Does anyone have any advice that I could try?

It's an LG with freezer on the bottom, it's a 2011. Model #is LBC22520ST

Hi @scate5 ,

Disconnect the power to the refrigerator for ~5 minutes and then reconnect it.

After it starts (or tries to) check what is being displayed on the freezer temp settings side of the display panel.

Normally it should display a 4 for both the refrigerator temp and freezer temp settings if everything is OK at startup.

Hopefully the lights will remain steady and give you an error code.

Here’s the service manual for the refrigerator. Go to p.27 to view the error codes and what their causes may be. Remember to only look at the freezer temp lights as according to the manual the refrigerator temp lights should be off if there is an error detected.

If no good try to get into Test Mode, as described on p.28 and see if you can run the diagnostics to find out what’s wrong.

If the refrigerator controls locks up or it doesn’t respond etc, simply disconnect the power to the refrigerator for a few minutes and then plug it in again.

Thank you so much.

I did try what you said and I read the manual, the numbers just continue to flash no matter what I try. It's exhausting... time for a new refrigerator.

Thanks again for your answer, I do appreciate it!

@scate5

It seems as though it might be in "Demonstration mode" for some reason?? Your description seems very close to what is described on p.28 i.e. "In this status, each LED is rotated with 1 second interval."

Not sure what "It reset if you do again as clause" means exactly to exit this mode but maybe try performing the same procedure used to enter Demonstration mode in Step.1 to exit it.
