One factor to consider is the age of your refrigerator. If it's more than fifteen years old, it may not be worth repairing because the cost of parts and labor may be more than that of a new fridge. However, if your fridge is under the fifteen-year mark, it's almost always worth the cost of repair.

Control Board. The control board is a vital part of the refrigeration process since no part of the fridge can function without it. This makes it one of the most expensive parts of a refrigerator to fix. If the refrigerator has stopped working suddenly, it may have something to do with the control board.

If the fridge isn't too old, repairs can often be relatively inexpensive — assuming they are covered under warranty — while potentially saving hundreds of dollars compared to purchasing a new unit.
