Refrigerator Circuit Board replacement

Not sure about the blue wire but the yellow stain indicates a cooling unit failure as newman fulltimer suggested. I wouldn't waste any money on a new circuit board.

I've seen where some folks have decided to change out the old fridge with an all electric fridge that's close enough to the same size, and do a little trim work to make it fit. It's a lot cheaper than a gas/electric.

it goes nowhere its a factory wire but seeing all that yellow your fridge cooling unit is toasted

OK, thanks! I'll replace the board and see how things go!
