Whirlpool refrigerator stopped working after power outage

Fridge worked fine and then we had the power go out for 3 days (Hurricane Irma).

Now it doesn’t work. The light comes on inside but the lights on the water dispenser and the dispenser itself don’t work…or the fridge.

Had it checked and the compressor is fine…they think it may be the control panel but won’t know until it’s replaced.

Thought I’d ask here in case there’s an easier fix I’m missing.

Thanks!
