Limit the number of times you open and close your refrigerator. Check for door-seal tightness by placing a piece of paper between the door gasket and the cabinet. If you can pull the paper easily, the seal should be replaced. Vacuum the condenser coils on the bottom or back of the unit twice a year to maintain peak operating efficiency. Never allow excess frost in the freezer.
Heavy frost overworks the the equipment.
Keep the oven door closed when cooking. If you need to open it, close it quickly to reduce heat waste. When using the oven, you can make full use of its heat by baking extra meals such as casseroles and meat loaves, and freezing them for later use. After you've finished cooking, use the remaining oven heat to warm plates and rolls. Ranges Make the pan size with the size of the cooking element or burner.
