What is the reason why the refrigerator is not refrigerating The lights will be on

The refrigerator is not refrigerated, it has little to do with the lamp, the lamp is just a lighting circuit, which can only show that the refrigerator can still supply power normally, and there are many reasons for not refrigerating:

1. The compressor is broken, if the power supply is normal, then we need to listen to whether the refrigerator has any sound, such as whether the motor is vibrating, if there is a hearing, it means that the compressor is fine, if there is no movement, it may be that the motor is burned out, then it is a tragedy, the compressor is the heart of the refrigerator.

2. If the compressor of the machine does not refrigerate, you touch the outside of the refrigerator box with your hands to see if there is any heat, if there is no or very low, it is a lack of freon, then you need to add freon. There is also a situation such as the battery valve with a battery valve is broken or does not work when it will not refrigerate.

3. If it is a machine with a temperature display, there is a possibility, that is, the temperature sensor is bad or the motherboard, of course, the light is on just to indicate that the power supply is still on, but it is necessary to further check, simply put, it is to see whether the thermostat is turned on, whether the compressor is started, if the compressor starts to run normally, it is the fluorine leakage of the refrigerator pipeline, and you need to find maintenance personnel to detect leaks, repair welding and refill fluorine.

4. If it is suddenly not refrigerated, it should not be a refrigerant leak, the general effect of refrigerant leakage is slowly not good, and the compressor should be started normally. It should be a control problem, change the compressor protector first.

5. Lack of refrigerant.

If it is caused by the lack of refrigerant, then its performance is obvious, first of all, it will not be refrigerated, it is the refrigerator, secondly, the evaporator of the freezer cannot be frosted, and then the freezer will not be refrigerated.

Extended information: Freon, also known as Freon, is derived from the English Freon, which is a refrigerant trademark registered by DuPont in the United States. In China, there are differences in the definition of freon, which is generally defined as a general term for halogenates of saturated hydrocarbons (mainly methane, ethane and propane), according to which freon can be divided into four categories: CFC, HCFC, HFC; Some scholars define freon as a CFC refrigerant; In some sources, freon refers only to dichlorodifluoromethane (CCL F, i.e., R12, a type of CFC).

The use of CFC-based refrigerants such as dichlorodifluoromethane has been restricted due to the destruction of the ozone layer in the atmosphere. There are many holes in the ozone layer on Earth, some of which are larger than Africa, and a large part of this is due to the chemical properties of CFC-like freons. Another hazard of freon is the greenhouse effect.

Causes: 1. It is caused by the poor closure of the refrigerator door (aging or damage of the magnetic sealing strip), the lack of refrigerant in the refrigeration system, too much ash and dirt on the surface of the condenser or too thick frost layer on the surface of the evaporator. These will make the compressor work for a long time, and the temperature will drop very slowly.

2. If there are oil stains on the outer surface of the refrigeration system, it means that there is leakage, which will cause the refrigeration capacity to decrease, and the frost will be uneven or incomplete on the surface of the evaporator, and the refrigeration system will completely lose the refrigeration capacity.

3. If there is frost or condensation on the gas pipeline, it may be that the refrigerant is overcharged, or the frost layer of the evaporator is too thick, resulting in the refrigerant liquid cannot be gasified well in the evaporator and reaches the suction pipeline for further heat absorption and gasification of frost and condensation. In severe cases, frost and condensation can appear on the compressor, causing the refrigerator to not refrigerate.

First, the power light of the refrigerator is normal and does not refrigerate, in general, there are two reasons:

1. The running indicator light is damaged or broken.

2. The thermostat is faulty, resulting in an open circuit.

Second, the solution that the refrigerator will turn on when the refrigerator does not cool the light:

1. Look at the refrigerator thermostat.

The refrigerator thermostat is installed in the refrigerator, and 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 limit the refrigerant temperature, which mostly occurs in air-cooled refrigerators.

2. Look at the temperature of the refrigerator.

The temperature of the refrigerator compartment is automatically adjusted with the temperature adjustment of the freezer compartment, and the temperature of the freezer compartment 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. Look at 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.

Generally speaking, the main reasons why the refrigerator does not refrigerate are:

1. The compressor runs but does not refrigerate: the high-pressure output buffer pipe in the compressor is broken, or the screw fixing the tube is loose, resulting in the high-pressure pipe not exhausting, and the low-pressure pipe not suctioning, resulting in the refrigerator not being refrigerated;

2. Refrigeration system problems: refrigerator refrigerant leakage or lack of fluorine, no refrigerant evaporation and heat absorption, refrigerator temperature does not drop, and can not be refrigerated;

3. Capillary blockage: frost in the evaporator. Generally speaking, air-cooled refrigerators have only one evaporator, and when the evaporator frost cannot be melted, the air duct mouth is blocked, and the cooling capacity cannot go out, resulting in the refrigerator not being refrigerated.

Common solutions:

1. Check the compressor: you can check whether the motor coil is burned out, and finally check the situation of the starter, sometimes the overheating protector is working, and it takes a certain amount of time to let the compressor temperature drop before it can be started;

2. If the refrigerant lacks fluorine or leaks, it is recommended to call the official after-sales service for repair and add refrigerant;

3. Check the defrosting situation of the evaporator to see if the defrosting timer is faulty, and if you find a problem, you should contact the after-sales service in time to deal with it;

4. In daily life, the common functions of the refrigerator should be checked regularly, and if there is a problem, the after-sales service should be contacted in time to avoid affecting the normal use in the later stage.

The compressor runs without refrigeration and is a lack of fluorine. The compressor is not running, and the case is cold because the thermostat is not working. The compressor is not running, and the casing is hot because the starter is broken.

It's best to find the after-sales service of your refrigerator brand, or you look at the manual, which light will be explained by this kind of light, you look for it.

The light can be turned on to indicate that the power supply voltage, plug, and socket are normal, which may be the fault of the thermostat and compressor, and follow the steps below for maintenance:

1.Check that the thermostat is in the correct position;

2.The thermostat is located in 3-4 gears, and the compressor does not start after the power is turned on, adjust whether the thermostat still does not start;

3.Disconnect the power supply and check whether the starting relay and thermal protector are normal;

4.Use the R 1 gear of the multimeter to measure whether the compressor starting winding is resistant;

If there is any of the above faults, the compressor can be replaced and repaired.

1. The refrigerator is not refrigerated, but the light will be on for the following reasons:

1) Leakage of refrigerant in the refrigeration system;

2) blockage occurs in the capillary tube of the ice-containing silver box;

3) The compressor of the refrigerator is faulty;

4) There is an oil jam in the evaporator of the refrigerator.

2. The solution of the refrigerator not refrigerating:

1) First of all, the light of the refrigerator is on normally, which means that the power supply of the refrigerator is in a normal state, and the refrigerator is not refrigerated due to power supply problems.

2) After that, check the thermostat of the refrigerator, because the thermostat of the refrigerator fails, which may cause damage to the evaporator defroster in the refrigerator, and then lead to no refrigeration;

3) After troubleshooting, check whether the compressor of the Boda refrigerator is faulty;

4) After troubleshooting, check whether the refrigeration system of the refrigerator is leaking or leaking.

5) After finding out the cause of the failure of the refrigerator, if you can't repair it, you need to base Lao Hui to come to the door as soon as possible to repair it.

Causes and elimination methods for compressors not working due to low indoor temperature in winter and refrigeration:

If the compressor starts to work after a while, it means that the indoor temperature of the refrigerator is too low, or the winter temperature compensation switch in the refrigerator is not opened, or the performance of the automatic compensation circuit is abnormal, or the damage of the compensation electric heater is caused.

Temporary emergency can be adjusted to the highest gear many times a day in the morning, noon and evening, so that the compressor can be forced to start the work and then a little more.

You can also buy a refrigerator companion online, also called the refrigerator bosom friend, adjust the boot time to the shortest, about 5 minutes, and then adjust the shutdown time to the longest, about two hours, plug the power plug of the refrigerator into the power socket on the refrigerator bosom friend, and then plug the refrigerator bosom friend into the power socket on the wall, and adjust the gear in the refrigerator to the highest gear.

If you pour a cup of hot water and put it in the refrigerator and the compressor does not start, it is estimated that the starter on the left side of the compressor is damaged.

If the refrigerator light is not on, it means that the refrigerator power supply is not on, and you should check whether the refrigerator plug is not plugged in properly or the socket is not powered. Otherwise, it is estimated that the compressor starter is damaged.

If the compressor does not work without stopping but does not refrigerate, it should be due to damage and leakage at a certain position in the system pipeline, resulting in the loss of refrigerant liquid.

There may be the following reasons why the refrigerator is not cooling:

1.Clogged pipes: Pipes in your refrigerator's refrigeration system can become clogged with dirt or ice, resulting in poor refrigeration.

2.Compressor failure: The compressor of the refrigerator is the core component of the refrigeration system, and if it fails, the refrigeration effect will be affected.

3.Condenser failure: The condenser of a refrigerator is a critical component in converting the refrigerant from a gaseous state to a liquid state, and if it fails, the cooling effect will also be affected.

4.Electronic controller failure: The electronic controller of the refrigerator is responsible for controlling the operation of the refrigeration system, and if there is a failure, the refrigeration effect will also be affected.

5.Refrigerant leakage: If the refrigerator's refrigerant leaks, the cooling effect will be affected.

Whatever the reason, it is necessary to find a professional maintenance personnel in time to repair it.

As for the light to turn on, this is because the light of Li Suiwei's refrigerator is independent of the refrigeration system, and even if the cooling system fails, the light will be on normally.
