refrigerator and freezer would not cool down.

First, we called Sears Repair and had a technician come to our home. He stated the motherboard had gone bad probably due to a power surge (we had no surge protector on the appliance). His price for repair was $465.00. We opted to go online for the part and found it for $165.00 through PartSelect.com. It was a very simple procedure of removing the old and installing the new. A few turns with the nut driver to uncover the part, a few tugs with the pliers to disconnect and voila!.. The fridge was back to cooling in no time.
