To extend the life expectancy of a refrigerator, provide it with proper care and maintenance, place it in a controlled climate and position it leaving sufficient space from the wall. Also, do not overload the refrigerator, and defrost the unit periodically, advises Appliance Parts Company.
Proper care and maintenance for the refrigerator includes regular cleaning of the condenser coils, door seals, drip pan and the interiors, according to SFGate. Remove dust, dirt and other debris from the condenser coils by vacuuming. Use soap and water to clean the door seals and to prevent them from cracking.
Also, empty and clean the drip pan with soapy water at least thrice a year. Similarly, empty and clean the interiors of the refrigerator once a month. Maintain the internal temperature between 37 and 40 degrees Fahrenheit.
Place the refrigerator away from direct sunlight and other appliances that produce heat. Additionally, leave several inches of gap between the coils at the back and wall to allow for ample air flow and proper cooling. Avoid overloading the unit as this leads to inefficient cooling of the food items and over-burdens the system. Finally, once every quarter defrost the ice build-up. Avoid ice build-ups of over quarter of an inch.
