When the refrigerator suddenly stops cooling, the food that should originally be stored in a low-temperature environment loses its protection. Fresh fruits and vegetables will gradually lose moisture and become shriveled; while fresh foods such as meat and fish will quickly breed bacteria and start to spoil at higher temperatures. Food that could have been stored for days or even weeks may become unfit for consumption within just a few hours.
This causes many inconveniences in life. Firstly, the waste of food is distressing. The ingredients purchased have to be discarded due to the refrigerator malfunction, which not only causes economic losses but also goes against the conservation concept we advocate. Secondly, the sudden failure to cool may disrupt our daily rhythm. The originally planned diet arrangements are disrupted, and we need to purchase food temporarily or find other storage methods. Moreover, in hot summer, without the refrigeration function of the refrigerator, the temperature in the kitchen will rise significantly, making people feel stuffy and uncomfortable.
In addition, the refrigerator’s failure to cool may also affect our health. If spoiled food is accidentally eaten, it may lead to health problems such as food poisoning, especially for people with weaker constitutions, such as the elderly, children, and pregnant women, the harm is even greater. Meanwhile, frequently handling spoiled food also increases our chances of coming into contact with bacteria, bringing potential risks to our health.
In conclusion, after the refrigerator suddenly stops cooling, the food cannot be kept fresh and is prone to spoilage, causing many inconveniences and potential health risks in our lives.
I. Analysis of the Reasons for Not Cooling
(A) Power Supply Problems
The normal operation of the refrigerator depends on a stable power supply. If the power plug is loose or not plugged in properly, the refrigerator will not receive electrical support and naturally cannot cool. In addition, circuit faults may also cause the refrigerator to stop cooling. For example, situations such as damaged power cords and short circuits in the circuit. To ensure the normal operation of the refrigerator, we need to regularly check whether the power plug is plugged in properly and also pay attention to checking whether the power cord is damaged. Additionally, we need to ensure that the voltage is within the normal range. Generally speaking, the voltage requirement for refrigerators is within 187 – 242V. If the voltage is not within this range, a voltage stabilizer needs to be equipped or professional personnel should be consulted to solve the problem.
(B) Compressor Malfunction
The compressor is a core component of the refrigerator, and its normal operation is crucial for the refrigeration of the refrigerator. If the buffer tube inside the compressor breaks or the screws are loose, it will affect the normal operation of the compressor, thus causing the refrigerator to stop cooling. When this situation occurs, the casing can be opened to replace the new buffer tube or tighten the loose screws. If the compressor is damaged, professional personnel need to be invited to carry out maintenance or replacement.
(C) Refrigerant Problems
The refrigerant is the key substance for the refrigerator to achieve refrigeration. If the refrigerant is used up or leaks, it will cause the refrigerator to stop cooling. When suspecting that the refrigerant is used up, the situation can be judged by listening to the running sound of the refrigerator. If there is no sound of flowing water after the refrigerator has been running for a while, it may be that the refrigerant is used up. At this time, professional personnel need to be invited to replenish the refrigerant. If the refrigerant leaks, the leakage point needs to be checked and repaired. However, the refrigerant is somewhat toxic, and professional personnel are required to operate to avoid harm to the human body.
(D) Capillary Tube Blockage
The blockage of the capillary tube will impede the flow of the refrigerant, thus affecting the refrigeration effect. The reasons for the blockage of the capillary tube may be dirt or ice blockage. If the blockage is caused by dirt, the capillary tube can be removed for cleaning. If it is ice blockage, the blockage can be eliminated by using the methods of hot compress or baking. If the blockage is serious, it may be necessary to replace the capillary tube.
(E) Thermostat Malfunction
The thermostat is an important part for controlling the temperature of the refrigerator. If the thermostat fails, it will cause the refrigerator to be unable to cool normally. The reasons for the thermostat failure may be contact adhesion, malfunction of movement, etc. When this situation occurs, it may be necessary to replace the thermostat. If it is not certain whether the thermostat is faulty, the situation can be judged by adjusting the settings of the thermostat. If the refrigerator still does not cool after adjustment, then it may be that the thermostat has a problem.
(F) Other Factors
In addition to the above common reasons, dust and oil stains on the condenser, loose door seals, faults of the starter or overload protector, excessively high ambient temperature, and refrigerator overload may also cause the refrigerator to stop cooling. Dust and oil stains on the condenser will affect the heat dissipation effect, thus affecting the refrigeration. The dust can be gently brushed off with a soft brush or the oil stains can be wiped off with a dry soft cloth. Loose door seals will cause the cold air to leak out, affecting the refrigeration effect. It is necessary to check whether the door seals are damaged and replace them if necessary. Faults of the starter or overload protector will also cause the refrigerator to stop cooling, and it may be necessary to replace them. Excessively high ambient temperature will affect the refrigeration effect of the refrigerator. Try to place the refrigerator in a well-ventilated and appropriately temperatured place. Refrigerator overload will impede the circulation of cold air, affecting the refrigeration effect. The items in the refrigerator can be reduced to ensure the free circulation of cold air.
II. Detailed Explanation of Solutions
(A) Power Supply Problems
If the power plug is loose or not plugged in properly, make sure the plug is plugged in tightly and connected firmly. Check whether the power cord is damaged. If any problems are found, replace the power cord. In addition, check whether the fuse is burned out and ensure that the circuit breaker has not tripped. If necessary, try inserting the refrigerator plug into other sockets for testing. If the voltage is not within the normal range (within 187 – 242V), a voltage stabilizer should be equipped or professional personnel should be consulted to solve the problem.
(B) Compressor Malfunction
When the buffer tube inside the compressor breaks or the screws are loose, open the casing, replace the new buffer tube, or tighten the loose screws. If the compressor is damaged, professional personnel must be invited to carry out maintenance or replacement.
(C) Refrigerant Problems
When suspecting that the refrigerant is used up, the situation can be judged by listening to the running sound of the refrigerator. If there is no sound of flowing water after the refrigerator has been running for a while, invite professional personnel to replenish the refrigerant. If the refrigerant leaks, have professional personnel check the leakage point and repair it. Do not operate by yourself to avoid harm to the human body.
(D) Capillary Tube Blockage
If the blockage is caused by dirt, remove the capillary tube for cleaning. For ice blockage situations, use the methods of hot compress or baking to eliminate the blockage. If the blockage is serious, replace the capillary tube. This operation should also be carried out by professional personnel.
(E) Thermostat Malfunction
When the thermostat fails, it may be necessary to replace the thermostat. If it is not certain whether the thermostat is faulty, first judge the situation by adjusting the settings of the thermostat. If the refrigerator still does not cool after adjustment, then it can be basically determined that the thermostat has a problem. Timely invite professional personnel to replace or repair it.
