What is the matter with the refrigerator not cooling but heating up

<> the refrigerator is heating and not cooling, and the compressor is running, it may be caused by improper adjustment of the temperature controller, uneven convection in the box, and loose sealing of the refrigerator door. In addition, too thick frost in the evaporator can also affect the refrigeration effect. If the surface of the condenser is too dirty, it will affect the heat radiation of the condenser to the space, and there will be blockage in the refrigeration circulation system, which will affect the normal refrigeration cycle.

If the refrigerator compressor is inefficient, there is too little refrigerant or there is leakage, the convection circulation between the evaporator and the stored food is disrupted, which can also lead to poor refrigeration. Once a fault is found, it can be checked from simple to complex to find the fault point. Once it is determined that it is a problem with the compressor, find a professional to come to your home to replace it.

If it is a clogged capillary problem, it can be solved by itself.

Normally, the repair requires dissecting the casing, disassembling the compressor, unscrewing the cylinder head screws, and checking the gaskets. If the condition is good, continue to unscrew the screws of the cylinder and the base to check whether there are cracks in the gasket around the cylinder. Cracks can cause slight collusion between high and low pressure cavities, causing failures.

Next, replace it with a new gasket of the same specification, seal the compressor, check for leaks, and install the refrigeration system.

If the refrigerator is hot to the touch, but it is not refrigerated, it may be because the external environment heat dissipation is too poor, which affects the refrigeration effect, or the refrigerator fan or defrosting circuit is faulty, the refrigeration system is leaking, etc., and you need to contact the after-sales service for maintenance.

When using the refrigerator, pay attention to the following aspects, which can prevent the refrigerator from heating up and affect the refrigeration effect:

1. When placing the refrigerator, do not close to the wall or other objects, do not cover things on the refrigerator, pay attention to ventilation, and keep the refrigerator with enough space to dissipate heat.

2. Do not open the refrigerator frequently or for a long time, which will lead to the loss of cold air in the refrigerator, so that the refrigerator will be in working condition for a long time, and the temperature of the refrigerator will rise.

3. Don't stop using the refrigerator often, it takes a long time for the refrigerator to reach the set refrigeration temperature, and frequent power outages and then restart will consume more electricity and aggravate the heating of the refrigerator.

1. When the refrigerator is running, the compressor will gather the heat in the refrigerant in the condenser, and the refrigerant will continue to release heat when condensing, if the heat wants to be dissipated, it needs to be higher than the temperature of the natural environment, and the refrigerant pressurized by the compressor continuously releases heat in the condenser, and then dissipates it through the condenser. Some refrigerator condensers are installed on the inside of the refrigerator outer panel, and then the outer wall of the refrigerator becomes a radiator, and people will feel that the refrigerator is hot when they touch the refrigerator shell.

2. The refrigerator generally relies on the evaporator for evaporation and heat absorption during operation, and the evaporator is usually installed in the back plate of the refrigerator, when the evaporator is evaporating and absorbing heat, the temperature of the inner wall of the refrigerator in contact with the evaporator decreases, and the inner wall will absorb the heat of the food, which is also the reason for the heating of the refrigerator.

1.In winter, the refrigerator is not refrigerated in winter, mainly because the indoor temperature is too low, and the refrigerator thermostat gear is adjusted too low, or the winter temperature compensation switch is not turned on, resulting in the compressor not starting and not refrigerating. In the case of the channel, the knob of the thermostat is adjusted to the highest setting, and the compressor can start normally, indicating that the above reasons are caused.

2.The temperature of the refrigerator is automatically adjusted with the temperature of the freezer, and the temperature of the freezer can be lowered. Generally, the temperature of the refrigerator room is 4-10 degrees Celsius.

Note that the higher the number of the temperature controller, the lower the temperature, the higher the number in summer and the smaller number in winter.

This should be because:

1. The refrigerator thermostat is abnormal.

2. Refrigerator refrigerant leakage.

3. The refrigerator pipe is dirty and blocked.

In a word, it needs to be repaired!

Pay attention to it, if it can't be automatically stopped, it is the pipeline leaking and the refrigerant has run out.

This is the refrigerator is broken and must be repaired, and I am really helping you look forward to it

This is the refrigerator is short of refrigerant, please ask a professional maintenance master to fix it.

1.The refrigerator is equipped with a corresponding cooling system. The refrigerator may be hot because the refrigerator does not have a radiator or there is a problem with the refrigerator's cooling system.

It's also possible that there is a blockage around the refrigerator's cooling system that is blocking air circulation. 2.Poor contact with the refrigerator power supply; 3.

The refrigerator thermostat is installed in the refrigerator room, and the temperature of the refrigerator compartment does not reach the temperature required by the thermostat, and it will not stop. Suggested workaround:1.

When placing the refrigerator, it is recommended that the refrigerator be placed in a location that is convenient for heat dissipation and keep an appropriate distance from the wall. 2.Sudden power failure at home, poor contact of refrigerator power plug, broken refrigerator power cord, disconnected power circuit breaker, etc.

It may cause the refrigerator to stop working suddenly, causing the refrigerator to heat up instead of cooling. The heat at this point is usually waste heat because the refrigerator has stopped working. Check if the refrigerator door light is on to determine if the refrigerator is powered on, check if the thermostat is in the working position.

The thermostat has a stop position, and when it is in the stop position, the compressor will not work. 3.If the compressor is working day and night, the freezer may create the maximum cooling temperature of the refrigerant.

This phenomenon mostly occurs in refrigerators in air-cooled refrigerators. The reason was that the frosting device of the evaporator in the cold room was broken, which caused the ice to block. It cannot be ruled out that the air cooler is broken, and too many items in the refrigerator block the air outlet, resulting in poor refrigeration effect.

The refrigerator does not refrigerate the factors as follows:

Reason 1: The indoor temperature of the refrigerator is too high, resulting in fluorine leakage in the refrigeration system, that is, the refrigerator is not refrigerated due to the lack of refrigerant.

Solution: Find a repairman, re-weld the pipe, and take the time to re-add the refrigerant.

Reason 2: Frost in the evaporator. The main reason is that the air-cooled refrigerator has only one evaporator, and when the evaporator frost cannot be melted, the air duct mouth is blocked, and the cold capacity cannot go out, resulting in the refrigerator not being refrigerated.

Solution: Check the defrosting system, it may be that the defrost timer is faulty, or the heating element has burned out.

Reason 3: The refrigerator has been used for a long time, and if there is a leak in the tube or evaporator, it will not be useful to add fluoride alone.

Solution: It is difficult to repair, and it is necessary to find the leakage point for maintenance, but it will not take long.

Reason 4: There is a problem with the refrigerator compressor, and the pressure of the compressor return pipe is too low, which will cause the compressor to fail to start, resulting in the refrigerator not refrigerating.

Refrigerator is a kind of refrigeration equipment that keeps a constant low temperature, and it is also a civilian product that keeps food or other items in a constant low temperature and cold state.

There are cabinets or boxes that freeze through compressors and ice machines, and storage boxes with refrigeration devices. Its invention can be traced back to the nineteenth century, and the world's first artificial refrigeration household refrigerator was born in 1879, after years of development and innovation, China began to produce household refrigerators in the second half of the 50s of the 20th century.

Evaporator frosting The evaporator of a refrigerator is located inside the refrigerator and is a very critical heat exchange component in the refrigeration system. However, if there is frost inside the evaporator and it cannot be melted in time, it will lead to the blockage of the air outlet, and the cold air cannot be transmitted to the refrigerator, and the refrigeration effect will naturally plummet. In this regard, the first thing to do is to check whether the defrosting system is faulty, such as whether the defrost timer is not working properly, whether the heating element has accidentally burned out, and then repair it after finding the root cause of the problem.

2. Compressor damage The compressor can be said to be the heart of the refrigerator, which can promote the circulation of refrigerant in the refrigerator, so as to achieve the effect of refrigeration, so the quality of the compressor will also determine the quality of the refrigerator to a certain extent. If the compressor is faulty or damaged, it will be more troublesome to repair. Whether the compressor is faulty can be easily identified, listen carefully to the "noise" emitted by the refrigerator, if there is no motor sound that is often there, it is likely that the compressor is damaged.

Of course, it is more reliable to let professionals carry out the test, as for the solution, if it can be replaced, it will be replaced, and if it cannot be replaced, you can only buy a new refrigerator. 3. If the refrigerant is not enough or the fluorine leakage is not enough The compressor is running normally and the evaporator is not frosted, the problem is likely to be the refrigerant, which may be the lack of refrigerant or the fluorine leakage in the pipeline. For the former, it is sufficient to add refrigerant in time, while for the latter, it is necessary to ask a professional to find the fluorine leakage site for targeted repair before adding fluoride.

The above is about what is the reason for the refrigerator heating and not refrigerating, and the solution and the reason why the refrigerator is not refrigerated.

Take a look.

If the refrigerator is hot but not cooling, it may be that the refrigerator thermostat control is malfunctioning; It is also possible that the high-pressure output buffer pipe in the compressor is broken, or the screw fixing this tube is loose, resulting in the high-pressure pipe not exhausting, the low-pressure pipe not suctioning, and the capillary blockage. It is only suitable for most brands of refrigerator models such as Gree, Haier, and Midea.

It may be that the high-pressure output buffer pipe in the compressor is broken, or the screws that fix this tube are loose, resulting in the high-pressure pipe not exhausting, and the low-pressure pipe not suction, so although the compressor is running, the refrigerator is heating but not refrigerating, or the refrigeration system is leaking, although the compressor is running, there is no refrigerant evaporation and heat absorption in the system, or it may be that the capillary is blocked, and the refrigerant cannot enter the evaporator to evaporate and absorb heat, so the temperature in the refrigerator does not drop.

It would be nice to ask the repairman to come and take a look?。。

The freezer has been used for a long time, there may be no refrigeration problem 1, test the power cord with an electric pen, the freezer power cord is broken is also a reason for not refrigerating, in this case we need to check whether it is a problem with the power supply, the general practice is to open the door of the box and observe whether the lights in the box are lit. Look for signs of damage to the wires, such as being bitten by a mouse. 2. The lack of refrigerant causes the freezer to not refrigerate

Most of the capillary outlets of two-door refrigerators are advanced to the freezer to start circulation, that is, to start cooling in the freezer. At the end of the cold room, if the refrigerant is lacking, it is first reflected in the fact that the refrigerant is not refrigerated from the cold room, and if the refrigerant is further insufficient, the freezer evaporator cannot be completely frosted. When the outlet of the air pipe is blocked, it will cause the problem of not refrigerating.

3. The freezer is not refrigerated due to frosting in the evaporator: when the frost in the evaporator cannot be melted away, the air duct mouth is blocked, mainly because the air-cooled refrigerator usually has only one evaporator, and the cold capacity cannot go out, resulting in the refrigerator not being refrigerated. At this point, the defrosting system needs to be checked, it may be that the defrost timer is faulty, or the heating element has burned out.

Questions. How to solve the heat in the freezer refrigerator.

Reason: Small space for heat dissipation, long time to open the refrigerator door, frequent power failure. Workaround:

1. The refrigerator is far away from the wall, and there is no space for heat dissipation when placed close to the wall. Causing the refrigerator to rise in temperature, you should keep enough space on both sides of the refrigerator to dissipate heat. 2. When using the refrigerator, do not open it too frequently, frequent opening will increase the temperature in the refrigerator and increase the workload of the refrigerator, and the temperature on both sides will increase if the refrigerator is in operation for a long time.

3. Once the refrigerator is used, it is best not to stop using it, because once it is out of use, especially in summer, when the temperature is very high, it will take a long time for the refrigerator to reach the set refrigeration temperature, and the temperature on both sides will increase after a long time of operation.

1. Power supply problems. First, check that the power supply is plugged in.

2. Compressor problem. Check that the compressor is working properly.

3. Whether the refrigerant is leaking. Check for refrigerant.

4. Fan problem. Check if the fan is working properly.

5. The influence of external temperature. Do not turn the refrigerator on and off frequently so as not to affect the temperature of the refrigerator. In addition, too much food storage will also have a certain impact on the refrigeration of the refrigerator.

This is a special fault and should be dealt with separately. According to the ordinary situation: the shell is hot, indicating that the compressor efficiency is relatively high, the internal circulation is normal, and the refrigeration effect is the best.

However, there are special faults such as the failure of the intercooling refrigerator fan or the defrosting circuit (defrosting heating tubes, fuses, timers, bimetals.

If the compressor is still running, then one possibility is that the ice is blocked, shut down for a while, and then turn it on again after a while to see if it can be refrigerated, if it still doesn't, the refrigerant may be leaking.

1. If there is a problem with the compressor, it will cause the refrigerator to strike and not refrigerate. 2. The thermostat of the refrigerator is not set reasonably, which will also affect the refrigeration function of the refrigerator. 3. The filter screen is blocked, which leads to a heavy burden on the refrigerator and will also affect the refrigeration effect.

4. The refrigerant in the refrigerator is insufficient, or because it is cold.

The refrigerator is not refrigerated, and there is a high probability that it is broken. It may be that the refrigerant is gone, or the pipeline is leaking, and someone needs to repair it.

Hope, thank you.

The reason for this phenomenon is that due to the long-term use of the refrigerator, the insulating material part of the box, due to thermal expansion and contraction and the internal skin of the box body has a slight separation phenomenon (serious internal box skin has been bulging), in the long-term use of the compressor internal parts wear, especially the suction and exhaust valve, the wear will not be too serious, in the vernacular is that the machine is a little difficult to work, the insulation is not good, etc., it is natural to produce the above phenomenon. To solve these phenomena, keep the refrigerator away from the heat source area, such as "unventilated places, places exposed to the sun, and so on." Clean the inside and outside at any time, stack the inside reasonably, defrost in time, arrange reasonably, and reduce the number of door openings.

Causes and elimination of abnormal refrigerator refrigeration 1. Fault phenomenon: sometimes the refrigerator is refrigerated normally, sometimes the refrigeration is abnormal, and even the cooling is difficult, and the compressor runs non-stop for a long time. If you stop using the refrigerator for a few days, you will be able to use it again.

This is due to the problem of the defrosting circuit, so that the evaporator can not be defrosted normally, when the frost layer on the surface of the evaporator accumulates thicker and thicker, blocking the circulation flow of cold air, reducing the heat absorption efficiency of the evaporator, thus causing the difficulty of cooling the refrigerator and the long-term operation of the compressor.

2. Elimination method: check the DC resistance value of the relay motor at the defrosting time with a multimeter, which is about 8,000 ohms under normal conditions. If the resistance value is normal, you can power on to check whether it is or not, listen to the sound of the motor moving, and there is a sound indicating that the motor can work.

If the defrost timer is damaged, it can be repaired or replaced. If the defrost timer is working normally, check the defrost thermostat again, when the ambient temperature is +13, this thermostat should be disconnected, if it is on, the thermostat is broken. If normal, this thermostat can be placed in the freezer of another refrigerator, frozen at a temperature lower than -5 for 10 minutes, and should be turned on when measuring with a multimeter r*1 gear.

If the defrost thermostat is damaged, it can be replaced with a new one.

3. If there is no problem with the defrosting thermostat, the defrosting heater and the drain heater should be further checked, their parallel resistance is generally about 300-320 ohms, if the heating wire of the heater is damaged, it should be replaced. At the same time, the defrosted fuse should be checked, it is disconnected when the temperature reaches 65-70, and it can only be replaced with a new one after disconnection.
