When it comes to troubleshooting major home appliance repair, it always helps to know a little something so that you can decide if your freezer or refrigerator is working properly. One of the most common mistakes that people make is assuming that a burned out light in a refrigerator or freezer means that the appliance is in need of repair. In almost every case, the appliance light is something that operates on its own. If something is going wrong with the appliance, then the light is not necessarily going to go out. The light is a regular bulb that will go out and need to be replaced from time to time. In most cases, a blown appliance light only means that it is time for a new appliance bulb.
Over time, you get to become familiar with the sounds that your freezer and refrigerator make. When you load up the refrigerator with food and close the door, you expect to hear that low thud as the motor fires up and delivers the cold air needed to keep the food preserved. You also come to realize that your freezer and refrigerator make very few distinct noises. When you hear a noise you have never heard before, then you know that something is not right. The best approach is to see if you hear the strange noise more than once. If you hear it more than once, then you need to call a repair technician because something is not right.
Another good indicator that your freezer or refrigerator is on the fritz is the presence of water either outside or inside the unit. If you notice that your refrigerator is getting slightly warmer and there are small puddles of water appearing outside the door, then there is something wrong. Some units will leak more from the bottom or the back than from the front. If you see a little water in the front, the move the unit to see if there is more water leaking from somewhere else. In either case, you have a problem that needs to be addressed.
Possibly the most terrifying sign that your freezer or refrigerator is not working is the smell of rotting food. If you go to bed and your refrigerator quits on you and then you go to work all day, you may not see your refrigerator for almost 24 hours. By the time you open it up, things could be going bad. This is an extreme case, but it can happen from time to time.
