After a power outage, the temp alarm began sounding. The temp and door alarm lights were lit. The temp displays were alternately supposedly displaying the current and highest temperatures but these values kept increasing. The electronic display control panel would not accept any inputs. After several hours the temp alarm stopped, the temp displays showed the original settings, but the door alarm light was still lit and the control panel still would not accept any inputs. The refrigerator and freezer appeared to be running normally but the temperatures, which were stable, were very low (25 degrees for the refrigerator and -10 degrees for the freezer). Presumably, either the display or main control board was damaged when the power was restored (it actually was restored twice; the first only lasted for a few seconds). The question is, which board is bad?

I'd suggest that you do a hard reset and check it again.

Unplug it for about a minute or two, then set the clock and try it again.

Let us know how it goes.
