Refrigerator Maintenance (Cheap, Minutes)

Refrigerators have metal coils on them to dispurse heat. They are usually underneath or behind the refrigerator, and they collect a LOT of dust. Take a few minutes every month or two, especially in the summer, to clean off the coils. There are special coil brushes available for around $5 - $10, but you can use the vacuum cleaner to get a lot of it. You may need to pull the refrigerator out from the wall to get at the back part, but be careful not to scratch the floor. There is also a vacuum attachment meant to get under furniture that can also help with dust under the fridge.

Make sure the temperature in your refrigerator and freezer is set to the right temperature. The recommended settings are 0°F for the freezer and 37 - 40°F for the refrigerator. Use a thermometer to make sure the temperatures are correct. If the temperature is not correct, do not change the control more than one number at a time. Allow 24 hours for the temperature to stabilize before making further adjustments.

Quick tips:

• Check door seals for proper fit to avoid air leaks. If you can easily slide a dollar bill between the door and the frame, adjust or replace the seal.
• Your refrigerator and freezer work most efficiently if they are one third to two thirds full. An empty refrigerator actually uses more energy.
• Cover all liquids and foods stored in the refrigerator.
• Make sure there is enough breathing room behind the refrigerator.

If your current refrigerator is 10 or more years old, it may be on its last legs. The typical life expectancy seems to be about 10 years. Consider an Energy Star model for greater efficiency. However, make sure you don't pay too much for it. It seems some manufacturers are pricing the Energy Star label models beyond what you could hope to save in energy.
