If you’re buying a new refrigerator, remember that top mounted freezers are cheaper to operate than side-by-sides, and don’t buy more refrigerator than you need. Automatic ice makers add about $200 to the initial cost of a refrigerator, cost about $50 a year to operate and are the first thing to break. If your refrigerator is old, check the seal by putting a dollar bill in the door. If it falls out, replace the seal. Keep the cooling coils in the back clean. And avoid repeated opening of your refrigerator door. When you’re getting ready to cook or cleaning up after a meal, make it a game to see if you can open the refrigerator door only once.
