Kenmore Elite Refrigerator not cooling; result of power surge?

Hi,

Last night, my house lost power briefly. This morning, I noticed that the LCD display and lights in the refrigerator were out, and I’m pretty sure the compressor is not running (don’t hear it, anyway). The refrigerator is about 2 years old.

The water dispenser LEDs on the freezer door and ice dispenser still work.

I’m guessing maybe a control board got fried? Can anyone suggest some troubleshooting steps? I have a multimeter and a reasonable technical background.

Thanks!
