Common Refrigerator Problems

Like other modern appliances, refrigerators have "turned digital," updating many components with more advanced ones as technological progress continues. Despite these changes, the way refrigerators work has not changed much, except that the refrigerant is no longer chlorofluorocarbons (like freon) but the new HFC (tetrafluoroethane), which is more respectful with the environment.

Undoubtedly, it would be good to read a good article about the basic operations of the refrigerator, as well as the manual and the user's guide that came with your appliance. When you understand how the machine works and you are particularly familiar with the specific model that is sitting in your kitchen (or anywhere), you will be much better prepared to realize that things are going badly.

Basic observations

Without going into the material you will study about your specific refrigerator, or spoiling the "introduction to the refrigerator" reading fun, let's review the basic concepts of the appliance.

Essentially, you have an isolated container (the "box") that uses chemical and electromechanical methods to extract heat from the inside. It is important to understand that refrigerators do not "cool" things as much as they eliminate and dissipate heat.

The chemical, HFC, changes from liquid to gas in a process called "vaporization". As it travels through a series of coils, in the back of the refrigerator and around the internal compartments, it switches from liquid to gas (and vice versa). ), extracts heat from the compartments and then dissipates it. That's why there are warm spots behind and below the device.

Leaks are not as common as in the old days, but they can still happen. Any whistling, liquid stains or loss of cooling efficiency may be attributable to a leak or valve problem.

Electric gremlins and humidity.

It may seem obvious, but the problems of the power supply start with the plug. If you lose power intermittently, check that your plug is fully inserted, that you have not removed the grounding plug and that you are in the appropriate house circuit. Numerous problems can arise when the feeding situation is not "cuppable," such as when you try to use a standard extension cord for the refrigerator. This is a fire hazard, as well as being a bad thing for the appliance.

If you notice condensation on the outside and / or inside walls and accumulates below the bottom drawers (on certain models), there may be a problem with the timer or the thermostat that help control the defrost cycles. Do not just clean the evidence without checking more thoroughly to find the cause (s) of the moisture.

Another accumulation that must be taken into account in frost-free models (in other words, all modern units) is: frost! If your freezer compartment does not stay away from ice and frost, which happens often enough to mention it here, then it is much more likely that you are facing a "programming" problem (timers, circuits) than a chemical one.

The isolation of the door is your friend.

Perhaps one of the most common problems with refrigerators of all ages is the isolation of the door that loses its flexibility and efficiency. If this material dries and starts to deform, crack or harden, it will not keep the air in the room out. This, of course, will lead to an increase in the interior temperature.

Check your insulation regularly and clean it with baking soda or a "silicone conditioner" available at the hardware store. You want to make sure that you get a tight seal when you close the refrigerator doors.

Like any modern appliance, you will "know" your refrigerator and become familiar with the sounds it makes, the appearance, and the amount of heat and (transient) condensation you will notice here and there during normal operation. When any of these indicators change, especially when they do it quickly, you can safely assume that something is wrong.

Just remember to use common sense. It is a machine that uses electricity, electromechanical components, chemical products and certain construction materials. All of these have normal operating conditions and ranges, any deviation from which you should be instructed to check the various systems. If you do not have enough knowledge to diagnose and repair problems, be sure to find someone who is!
