Most refrigerators are designed to last 10 to 20 years. If you have any of the other problems on this list and your refrigerator is more than ten years old, you'll likely save more money in the long run by simply replacing it. Otherwise, you could invest money in repairing a refrigerator that is already about to run out. No one wants to open their refrigerator and discover that the food they just bought has spoiled prematurely.
Food safety regulations dictate that you should keep your refrigerator at 40 degrees Fahrenheit, approximately 5 degrees Celsius. If food spoils before the expiration date, it's a cause for concern. The problem arises when the temperature adjustment knob does not work properly, causing the temperature inside the refrigerator to rise. Before scheduling a repair or replacement of your refrigerator, make sure that the knob is not the problem.
Depending on the quality of the refrigerator when you bought it, they can usually last 10 to 20 years. If you're having problems with your refrigerator, you should weigh the costs of a new refrigerator against what it would cost over time if you made regular repairs. It may be a better investment to shell out the money to buy a new refrigerator. Any large appliance will emit some kind of noise, which is not a cause for alarm. But if you notice an unusual noise that has started to come from your refrigerator, such as a buzzing or rattling sound, your refrigerator may be trying to tell you that it has problems.
To fix this problem, unplug the refrigerator for about 15 to 30 minutes. Make sure that you don't frequently open the refrigerator or freezer doors while they are turned off so that you can keep as much cold air inside. Then plug it back in and check if it emits the sound again. Doing so could mean that your refrigerator is running low and needs to be replaced.
