Our Frigidaire FLHS237ZAB6 is way too cold on the refrigerator side. It's actually freezing some items. We have lowered the temp to it's lowest setting, but it's still freezing cold.

I have done some basic research here and found that we may need to replace the Control Box Assembly which is expensive at $300+. It seems this unit has many parts built-in. Wondering if there is any way to narrow down the problem to a specific part to save some money, rather than replacing the entire Control Box Assembly. And if not, can our problem be anything else other than the Control Box Assembly?

Any input is appreciated! BTW, I do have a multimeter and can check continuity.
