Bad Controller Board?

I had a power outage yesterday and today I realized that the only thing working in the fridge are the interior lights. no panel/water/ice/cooling at all. No clicking sounds, nothing. Only the interior lights.

I’m guessing this is a problem with the control board? Is there a way I can verify it? There is a faint dusting on one of the mosfets(?) which have a heatsink attached to it. I have no problem using a multimeter, I just don’t know what exactly to check.

It was in fact the controller board. I took the $ gamble and swapped it out.
