This system uses heaters to melt frost and evaporate the water after the compressor has run for a certain number of hours. Automatic defrost is a common feature in new refrigerators, and saves you the trouble of defrosting a unit yourself. This is something that many shoppers don t consider when comparing models. This will come in handy if you ever need to store larger items, such as a turkey or tall bottles. Removable shelves are also easier to clean.
Some models feature tempered glass shelves, which confine spills to a single level.
However, these shelves may inhibit air flow within the unit. Insulation and seals Check the level of the unit s insulation in the manufacturer s specifications. In other words, the higher the number, the better insulated the unit is, and the less its compressor will have to run to keep it cold. Also check the door seals carefully to make sure they seal all the way around the door once it s closed. Extra features Icemakers and water dispensers may be more trouble than they re worth.
