Why Do Refrigerators Make a Popping Noise?

If the noise does not seem to be coming from outside the refrigerator, it is likely that the noise is being produced within the unit itself. A popping noise can occur in a refrigerator for several reasons, but usually it means that the temperature in the refrigerator has fluctuated beyond a certain point and has become too cold or too warm. When this happens, there is a change in pressure which causes some of the internal parts of the unit to move very quickly which creates a popping noise. The temperature then adjusts and everything goes back to normal.

How to Fix Your Refrigerator

If the popping noise occurs when you open or close the door, the problem is usually easy to fix. The most common cause of this issue is that there are too many items in your refrigerator. To fix the popping noise, remove some of the items from your refrigerator, so that it is not overstuffed and there is plenty of air circulating inside. You may also want to keep the door cracked open a bit after you use your refrigerator so that warm air can circulate and help cool it down more quickly. Keeping a special thermometer inside your refrigerator can let you know if the temperature has been too low or too high and help you determine what needs to be removed from it.

If your refrigerator makes popping noises when it is turned off but not being used, then there are other issues. One possibility is a noisy fan. In this case, you will need to replace the fan or at least have it cleaned and lubricated so that it keeps working properly. If the noise is coming from inside your refrigerator, then the smell coming from it may be a sign that something is wrong with the unit.

In many cases, if you are able to identify one of these issues with your refrigerator and fix it, you should find that the popping noise no longer occurs. If you are still hearing the noise, then one of the other issues has occurred and you will need to check that problem first.

When it is all said and done, there are many different causes for a refrigerator to make popping noises. Some of them are easy to fix, while others may require a replacement unit altogether. If you do experience this problem with your own unit but can identify one of the issues listed above, you may want to hire a repairman in order to have your unit repaired correctly and in a timely manner.
