Temp won't adjust ???

Hello All,
We have an electrolux side by side model EL23CS556S1. Recently after a brief power outage the temp in the fridge didn't seem to be as cold as preferred. We attempted pressing the down arrow to lower the temp, but nothing happens. The freezer seems to be fine.The "fridge" temp is at 37 degrees Fahrenheit but I like my milk a little colder than that. Any ideas ???

I do not know your refrig at all, but try pushing up and down arrows at same time, the set point should come up flashing, then lower to required set point then re-push up and down arrows again to set.
After power failure the controller may have reverted to factory settings.
Do know but try it anyway. Good luck
