I have an electronic Kenmore refrigerator 596.50013100. I bought it
from a private party over a year ago and it has been working great
until now. It seems very well made, overall.

Yesterday it started beeping and displaying a strange trouble signal:

It is right above the word "Kenmore", is red and looks like a crossed
lock and an exclamation.

The temperature in the unit has been rising since then and clearly, it
is not cooling anything. Right now both freezer and fridge are at 46
degrees F.

I tried calling Kenmore, but could only speak to dummies who are
forbidden to give any diagnostics.

My question is WTF does this sign mean? It is meant to tell me
something.

Thanks
