What is the reason why Meiling BCD 212ZE3 B refrigerator is not refrigerated?

1.Reason 1 for the refrigerator not to refrigerate: The indoor temperature of the refrigerator is too high, resulting in fluorine leakage in the refrigeration system, that is, there is no refrigerant to cause the refrigerator to not refrigerate.

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

2.Reason 2 for the refrigerator not to refrigerate: 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.

3.Reason 3 for the refrigerator not to refrigerate: 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.

4.Reason 4 for the refrigerator not to refrigerate: 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 not start, resulting in the refrigerator not being refrigerated.

Solution: Check whether the refrigerator power plug is plugged in properly, or the power supply is insufficient, etc.

According to the situation you described, it should be a refrigerant leak. Note that sharp objects should not be used when defrosting, as it is easy to injure the refrigeration pipe and lead to refrigerant leakage. Contact customer service directly to check and deal with it.

There is a leakage point to suppress it to see whether it is a high-pressure leak or a low-pressure leak to fill the leak and add refrigerant about 200 I am also a small county.

Look at your description, if you are in a hurry when de-icing, knock the ice with a sharp instrument, and accidentally leak the fluorine pipe, you will lack fluorine, and the machine will not be refrigerated. There is also a cool air circulation on the surface of the air-cooled evaporator, and there is a machine sound when the machine is turned on, which is like your friend said that the thermostat is broken, or the wiring is loose, and you have to find a professional to determine.

Hello dear and happy to answer for you. Found for you: Causes and solutions:

1。There may be a problem with the power supply. Check if the power connection is normal.

Open the door and observe whether the light in the box is on, or use an electric pen to test whether the socket has electricity. 2.The refrigerator compartment of the refrigerator is not refrigerated.

It could also be because the compressor is malfunctioning. When the compressor is working normally, it will emit a slight vibration motor sound. If there is no sound, the compressor is out of order.

You can ask a professional to repair or replace the compressor. Other causes and solutions:3.

Sometimes the compressor of the refrigerator is running, but the refrigerator compartment is not cooling. It may be that the refrigeration system of the refrigerator is leaking, and there is no refrigerant evaporating and absorbing heat in the system, resulting in the temperature of the refrigerator refrigerator not dropping, resulting in the situation that the refrigerator cannot be refrigerated. You can let the fridge run for a few minutes and then unplug it and listen carefully to the sound of the liquid flowing in the copper tube.

If not, the refrigerant in the system has leaked. If this happens, you can ask a professional to repair it. 4.

If the frosting device of the evaporator in the refrigerator freezer is broken, causing ice blockage, it will also cause the refrigerator freezer to not refrigerate. It is enough to replace it with a new frosting device. I hope mine can help you and have a great day

Summary. First, the evaporator problem The second reason for the high temperature is the frost in the evaporator, this situation is mainly for the air-cooled refrigerator, this refrigerator has only one evaporator, when the frost on the evaporator can not be melted away, the air duct will be blocked, and the cooling capacity can not go out, so the refrigerator can not be refrigerated. This can happen because there is a problem with the defrost system, either because the defrost timer is faulty, or because the heating element has burned out.

Second, the refrigerant problem The temperature in the refrigerator is high, which has two situations: the first is the fluorine leakage of the refrigeration system, that is, there is no refrigerant, although the refrigerator has been running, but the temperature in the box can not drop, after too long, the food in the box will be broken, so it should be repaired in time. Generally, as long as it is not a new refrigerator, this kind of situation is very slow, its early stage is in the refrigerator room has half of the frost, and the other half of the frost, the frost side is thicker, after a long time, there will be no frost in the refrigerator, at this time there may only be some water balloons, the temperature in the box is higher.

This kind of refrigerator is generally difficult to repair, because the leakage point is difficult to find, so it can not be used for a long time after repairing.

Dear, it is caused by these reasons.

First, the evaporator problem The second reason for the high temperature is the frost in the evaporator, this situation is mainly for the air-cooled refrigerator, this refrigerator has only one evaporator, when the frost on the evaporator can not be melted away, the air duct will be blocked, and the cooling capacity can not go out, so the refrigerator can not be refrigerated. This can happen because there is a problem with the defrost system, either because the defrost timer is faulty, or because the heating element has burned out. Second, the refrigerant problem The temperature in the refrigerator is high, which has two situations:

The first is the fluorine leakage of the refrigeration system, that is, there is no refrigerant, although the refrigerator has been running in the liquid huai, but the temperature in the box can not drop, after a long time, the food in the box will be broken, so it should be repaired in time. As long as it is not a new refrigerator, this kind of situation is very slow, its early stage is in the refrigerator room has half of the frost, and the other half of the frost, the frost side is thicker, after a long time, there will be no frost in the refrigerator, at this time there may only be some water balloons, the temperature in the box is higher. This kind of refrigerator is generally difficult to repair, because the leakage point is difficult to find a troublemaker, so it can not be used for a long time after repair, if the leakage point is still relatively Zou found outside, it can be dealt with by oxygen welding at this time.

3. The compressor cannot be started 1. The thermostat cannot be reset, because the contacts are sintered together, so that they cannot be separated, resulting in failure. 2. Whether the compressor is burned out, you can check whether the motor coil is burned and broken, check the situation of the starter, sometimes the overheating protector is in effect, and it takes a certain amount of time to let the compressor temperature drop before it can be started. 3. Whether the refrigerator has power supply, we can open the refrigerator door, if the inner light can be on, it means that the refrigerator has electricity, if the light is not on, you can check whether the total power supply has electricity, and then check the fuse of the Bingyu Mengyou box (not all refrigerators have), and check whether the contact of the thermostat has a problem.

Meiling refrigerator BCD a 230VP3B can not be refrigerated, 1, the refrigerator thermostat is installed in the refrigerator, the temperature of the refrigerator does not reach the temperature required by the thermostat, so it does not stop. If the compressor does not work around the clock, the freezer compartment may cause the refrigerant to reach the maximum refrigeration temperature. Most of this phenomenon occurs in air-cooled refrigerators.

The reason is that the evaporator flower froster in the cold room is broken, which produces an ice blockage. It cannot be ruled out that the air cooling fan is broken, and there are too many items in the refrigerator to block the air outlet, causing poor cooling effect. 2. The temperature of the refrigerator of the direct cooling refrigerator is automatically adjusted with the temperature adjustment 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. In addition, the refrigerator door is often opened, and there are many items in the refrigerator, resulting in the refrigerator not being refrigerated or the refrigeration effect is not ideal.

3. The reason why the refrigerator is not refrigerated may also be that there is a problem with the refrigerator compressor. The compressor can start, remove the return pipe and block the outlet with your fingers, check how much the pressure is, if it is too low, then there is a problem with the compressor The compressor can not be started, check whether the refrigerator power supply is plugged in. 4. Open the door of the refrigerator and see if the light in the box is on to determine whether the power of the refrigerator is turned on.

If the light is not on, use a pen or multimeter to check whether there is electricity in the power socket and whether the power plug of the refrigerator is well plugged in. 5. Use a multimeter to check whether the power supply voltage is lower than 187 volts, because the normal use voltage of the refrigerator is 187V 242V according to the national standard (unless otherwise stated by the manufacturer), and the compressor of the refrigerator below 187 volts cannot be effectively started normally. 6. When the ambient temperature is lower than the normal starting temperature of the temperature controller, check whether the low temperature switch of the refrigerator is turned on.

Check to see if the power plug of the refrigerator is not plugged in well, loose or falling off, and at the same time, it is necessary to ensure that the socket used in the refrigerator can be energized normally, you can change the socket or jack and try again, if it still doesn't work, it may also be that the terminal in the refrigerator power cord is not connected well, this nonsense is that you need to disassemble the power plug and reconnect it.

If after the above inspection and maintenance, the refrigerator still cannot be powered on normally, the hand shed may be a machine failure in other aspects, it is recommended to call the after-sales maintenance ** for help.

The refrigerator is now a household appliance that is inseparable from the family, in fact, many friends do not pay much attention to the ways and means of food storage, in the long run, this will not only have a bad impact on the food but also on the refrigerator, and then I will tell you about some of the wrong methods that are often seen:

1. If you have too hot food, you should not put it in the refrigerator that is being refrigerated immediately. Because the heat content of the food is very high at this time, the temperature in the box will rise sharply after being put into the refrigerator, increasing the thickness of frost on the surface of the evaporator, causing the compressor to work uninterruptedly, and the power consumption will increase significantly.

2. The food stored in the refrigerator should not be too full and too tight, and there should be a certain gap when it is finished, which is conducive to the flow of cold air in the box, reduces the load of the unit, prolongs the service life, and can also save electricity.

3. Do not mix raw and cooked food on the same layer to maintain food hygiene.

4. Do not put the food directly on the surface of the evaporator, that is, on the tray of the refrigerator, but put it in the utensils and then put it in the refrigerator, so as not to freeze the food on the tray and it is difficult to take it off.

A refrigerator is a kind of refrigeration equipment that maintains a constant low temperature, and it is also a civilian product that keeps food or other items in a constant low temperature state. Inside the box there is a compressor, an ice machine for freezing cabinets or boxes, and this front has a storage box with a refrigeration device with a split sail. The volume of a domestic refrigerator is usually 20,500 litres.

In 1910, the world's first compression-type refrigerated household refrigerator was introduced in the United States.
