The control board is $165 plus shipping by the link you sent.
I have found one on ebay for $65 with free shipping. Is that a safe option?
I can buy a fridge that is about 5 years old for $250
Can you tell how old this broken unit is by the model/serial number?
It came with a rental house I bought. If its older than dirt I'm going to be more inclined to replace it than repair it. This may just be the first of many porblems.
