Flashing display, clicking and now not cooing

My Whirlpool GC1SHAXMB00 side-by-side refrigerator’s digital display was flashing and I could not set the temp and no other function would work. Then it started to click, and now the fridge is not cooling. The freezer is still cold. I’m wondering if it’s the main board. Any help would be greatly appretiated. thanks…
