The compressor is a crucial part of the refrigeration cycle, which is the process whereby heat is removed from inside the refrigerator to keep it cool. The compressor pressurizes the refrigerant gas, which is converted into a liquid when it passes through the condenser coils. The liquid evaporates and absorbs heat from the interior of the fridge and cools it down. The cooled air is then circulated throughout the refrigerator to keep the food items cold. The gas returns to the compressor where it begins this cycle again. In summary, the compressor is responsible for pressurizing and circulating the refrigerant throughout the refrigeration system and facilitating the removal of heat from inside the refrigerator to the outside environment.

If the compressor overheats, it may be unable to compress refrigerant gas effectively, resulting in reduced cooling capacity and longer cooling cycles. It will also consume more energy as it struggles to maintain the desired temperature inside the refrigerator. This can lead to higher electricity bills and unnecessary energy use. Furthermore, overheating over a long period of time can damage the internal components of the compressor, such as the motor windings, and electrical connections. Over time, this can lead to premature compressor failure and the need for costly repairs. If the compressor continues to overheat, it may eventually fail completely. A failed compressor can cause the entire refrigeration system to stop working, leaving your refrigerator unable to function at all. Therefore, if you notice that your compressor is getting hotter than usual, you should address this promptly.

How Dirty Refrigerator Condenser Coils Lead to a Hot Compressor

The condenser coils are designed to release heat generated from inside the refrigerator. When these coils are covered in dust, dirt, or debris, they will be unable to carry out this function efficiently and the overall temperature of the refrigeration system increases. As a result, the compressor has to work harder and run more frequently to maintain the desired internal temperature. Over time, this constant strain can cause the compressor to overheat, increase energy costs, and lower the overall efficiency of the refrigerator.

How to Clean Condenser Coils to Fix a Hot Compressor

1. Before you begin cleaning, unplug the refrigerator from the power outlet to avoid electric shock.
2. You can typically find the condenser coil either on the back of the refrigerator or underneath the door behind a grille.
3. If the coils are at the bottom, you may need to remove the access panel or grille covering them. This may involve unscrewing a few screws or simply snapping off the grille, depending on your refrigerator model.
4. Once you have access to the coils, use a coil cleaning brush or a vacuum cleaner with a brush attachment to remove any dirt or debris. Be careful to avoid damaging the coils.
5. For any hard-to-reach areas where dust may accumulate, you can use a narrow brush or a can of compressed air to reach these areas.
6. Once the coils are clean and you’ve inspected them for damage, reassemble any panels or grilles you removed and plug the refrigerator back into the power outlet.
