Like most products, the lifespan of your refrigerator can be greatly extended with simple maintenance. The first item on the maintenance list of things to do and the top priority should be cleaning. This not only includes the interior of the refrigerator walls but also all plastic door shelves, glass covers, crispers and even the rubber door seal.
But above all, it is most important to clean the underside of the refrigerator where the condenser motor and coil are located. This is the favorite spot for lint and dust to accumulate which can make your refrigerator work harder than it has to causing the motor to overheat and eventually can shorten the lifespan of a very valuable and sometimes very expensive appliance.
It may look intimidating but it is really quite simple. The first precaution is to unplug the refrigerator. Then remove the ventilated cover at the front bottom. This piece usually just snaps on and off. Next using a long brush ( a dryer lint brush works well ), gently clean the lint and dust that has accumulated on the underside of the refrigerator. Finally vacuum everything that has been cleaned. It is that easy. A good rule of thumb is to do this every 6 months. Take care of your refrigerator and it should last a long time.
