Q's Daily DIY Green Tips: Refrigerator Seal Test
We've discussed how we ought to make sure our refrigerator door closed as often as possible, but how can we be sure the seal of the refrigerator is tight enough? One way to find out is to perform a paper test, or "dollar bill test." Close the refrigerator door over a piece of paper or a dollar bill. If you can slip a piece of paper between the refrigerator seal and itself, it is likely time to adjust the door or even replace the gasket. The tighter your refrigerator door, the less cold air will escape!
