Clean the coils on the bottom of the fridge. Keep this clean as it helps the air to circulate in and out of the refrigerator and keeps the compressor from burning out. Some estimate this can extend the life of a fridge by 10 to 15 — maybe even 20 — years!
Keep refrigerator full – but with caution. Obviously, the more items that are in the fridge, the less air it has too cool. At the same time, you don’t want to cram it so that air can’t flow efficiently through the unit.
Watch the vents. Speaking of having efficient flowing air through the fridge, there are vents inside the repairman reminded us to keep clear. So, make note of vents inside the unit and move any items around to give them adequate space.
Keep seals clean. Obviously, a properly sealed fridge is going to keep the cold air in and the hot air out. You can clean the seals with soap and water. To test if your seals may be replaced, place a piece of paper between a closed refrigerator door and if it falls out, you’ll need to replace them.
Organize! Another sometimes overlooked item but simple to do, is to keep items in the fridge properly organized. This helps you get in and out of the unit faster and lets less cold air out. This also goes back to helping the air flow within the fridge.
