Clean Your Condenser Coils Twice a Year
Dusty coils make the compressor overwork and shorten its life.
Condenser coils release the heat your fridge pulls out of the cabinet. When they're caked in dust, the compressor runs hotter and longer and cooling drops. Vacuum or brush the coils at the back or base every six months. This is the single cheapest way to extend a refrigerator's life.
