Every refrigerator has one. This is a gasket (or seal) that is made out of molded rubber.  The function of the gasket is to keep cold in and to keep heat out of the refrigerator. Essentially, it seals the colder air in, and prevents air outside the refrigerator from seeping in. The reason this matters is because a bad or worn seal will allow cold air to leave the refrigerator, and warm air to enter it. This means that temperatures in the refrigerator could increase, causing the food inside it to spoil more quickly. It will also cost you more money in energy. If there are gaps between the gasket on the door and the refrigerator gasket, it’s not sealing correctly.  One way to tell that you need a new gasket is if your refrigerator seems to be running more frequently, or you just think it seems like it’s losing cold air. You could also inspect the door gasket for condensation or blackish mold. If you see either of those things, you probably need a new gasket because the cold air is making the water in the warm air condense. If you see cracks or thinning of the gasket, it’s also probably time for a new one. You could also test the gasket with a dollar bill. Put the dollar bill between the refrigerator door and refrigerator, and close the door on it. Then, try to pull it out slowly. If you feel it drag slightly, your gasket doesn’t need replacing. If it slips out quickly or has moisture on it or mold, get a new gasket. You will need to do one of two things: repair the gaps in the gasket or replace it altogether. Replacing a faulty seal will save you money by not wasting energy. It’s not very expensive to buy a new gasket. It just costs about $50 to $75, and it should only take about 30 minutes to replace. You will save energy, so it will pay for itself fast. *Close the refrigerator door and look at the gaps. Inspect them. How big are they and where are they?  Use petroleum jelly on the gasket to fix small gaps. Simply pull the gasket away from the channel to expose a couple of inches (.05 meter) in the door corner. Cut small strips of weather stripping. Pack the corner with it by placing it along the channel of the door gasket. Push the gasket back in the channel. Repeat the process, and pack other corners if you think that’s needed. Close the refrigerator door again and look for gaps again. If this didn’t work, and you still see gaps, you will need to replace the seal.
