I installed a surge protector on the electrical outlet that powers my LG refrigerator as recommended by the repair tech after my first warranty repair (refrigerator fan and main board). The board that was replaced actually had a burn mark on it where one of the components had fried. Standard computer plug strip surge protectors may not be large enough for a refrigerator load. I used a plug-in surge protector that is made for use in offices for copiers and large printers since it has the capacity to handle a refrigerator load. Make sure it is one that does not cut off power so the refrigerator will continue to operate if the protector is overloaded or fails.
