Common causes of refrigerator failure and corresponding solutions

Creating a cozy and peaceful summer home requires carefully selected appliances that enhance comfort without sacrificing style and efficiency. Appliances 4 Less springfield offers residents of Bolivar, aMarshfield, Willard, Nixa and Seymour a selection of opened, scratched and dented appliances that are perfect for your summer living. Here is our guide to the must-have appliances for a cozy summer home.

Refrigerator, as one of the core household appliances of Modern Family Life, is to protect our food fresh, convenient life behind the scenes. It operates 24 hours a day, keeping ingredients fresh and tasty. However, a malfunctioning refrigerator can disrupt the rhythm of our lives. From the power circuit appear imperceptible subtle fluctuations, to the compressor, thermostat and other core components quietly failure, any seemingly insignificant small link, may become the culprit of the refrigerator strike. Make our lives inconvenient.

(1)、Power and circuit problems

1. power failure

Power supply and circuit is the lifeline of the normal operation of the refrigerator, once there is a problem, the refrigerator may strike.

①. Reason

Power supply is the basis of the normal operation of refrigerators. When refrigerators suddenly strike, the first thing to check is the power problem. Damaged sockets, broken power cords, or poorly connected plugs can cause refrigerators to lose power. Socket after a long time to use, the internal metal loose, can not be in close contact with the plug, the current can not be smoothly transmitted to the refrigerator. In addition, the family pet gnaws the power cord, the power cord aging cracking and so on the situation, also can cause the electric circuit interruption.

②. Solutions

Double-check the socket is normal, you can use other electrical plug the same socket test. If the socket damage, timely replacement; check whether there is damage to the power cord, if so, need to replace the new power cord. In addition, make sure that the plug is in good contact with the socket. If necessary, adjust the plug position or replace the plug.

2. voltage instability

①. Reason

Voltage instability is also a common cause of refrigerator failure. During the peak period of electricity consumption, the household voltage may be reduced, and the refrigerator compressor has a certain requirement for voltage. Too low voltage will lead to difficulty in starting or weak operation of the compressor, which will affect the refrigeration effect. Conversely, too high a voltage can damage a refrigerator's electronic component and shorten its life.

②. Solutions

Install a high quality regulator that automatically and accurately regulates voltage at all times. In daily power consumption, strictly plan the use time of electrical appliances, especially in the peak period of power consumption, resolutely eliminate multiple high-power electrical appliances at the same time, all-round stability of household voltage.

(2)、Compressor and refrigeration system failure

Compressor and refrigeration system failure, refrigerator refrigeration function will be greatly reduced.

1. compressor damage

①. Reason

The compressor is responsible for compressing the refrigerant and driving the refrigeration cycle. Long-term use, the compressor internal parts will gradually wear, resulting in performance degradation. When the compressor damage, the refrigerator will not refrigeration or refrigeration effect is very poor.

②. solutions

If you suspect damage to the compressor, do not disassemble the maintenance, should contact the professional maintenance personnel. Maintenance personnel through professional testing equipment to judge the failure of the compressor, if the damage is serious, may need to replace the compressor.

2. clogging of capillary or drying filters

①. Reason

As the finest throttling component of the refrigeration system, the capillary tube is easily blocked by tiny impurities or water ice crystals. The function of the drying filter is to adsorb water and impurities. If it fails or becomes saturated, it will lose its protective effect, the flow of refrigerant will be blocked, and the cooling effect of refrigerator will be reduced or even disappear.

②. Solutions

If your refrigerator fails due to clogged capillary or drying filters, you should contact a maintenance professional. They will accurately determine the location of the plug, using professional tools to remove the plug parts, cleaning or replacement, and then re-assembly debugging, so that the refrigeration system back to normal operation.

(3)、Temperature control system failure

The temperature control system precisely controls the temperature in the refrigerator. If it breaks down, the refrigerator's cooling rhythm is disrupted.

1. thermostat failure

①. Reason

The temperature controller is the key to the precise temperature control of the refrigerator. It senses the temperature change in the box with the temperature sensor, and then accurately controls the start and stop of the compressor. If the temperature sensor fails, or the temperature setting is wrong, the refrigerator will not be able to accurately sense the temperature, there will be continuous cooling or no cooling.

②. Solutions

Check the thermostat setting and adjust the temperature according to the season and food storage requirements. If the thermostat is damaged, it needs to be replaced.

2. sensor failure

①. Reason

There are also a variety of sensors inside the refrigerator, such as temperature sensors, door sensors, etc. , they are responsible for the refrigerator information to the control system. If the sensor fails, it will affect the monitoring and adjustment of the internal environment of the refrigerator, resulting in functional abnormalities.

②. Solutions

When refrigerators appear abnormal alarm or function failure, may be sensor failure. Contact professional maintenance personnel, the use of professional tools to detect whether the sensor is normal, if damaged, timely replacement.

Conclusion

As intractable as refrigerator failures may seem, we can take the time to restore them to health when they occur, provided we understand the common causes and know how to fix them, let it continue for our daily preservation escort, let every moment of life is filled with fresh and beautiful.
