The lights in the refrigerator are on, and the upper and lower boxes are not refrigerated

1. If the thermostat is mechanical, check whether the gear of the thermostat is adjusted at the 0 gear, which should be adjusted to the appropriate gear according to the seasonal ambient temperature, and the summer temperature should be adjusted at the 1-3 gear.

2. Does the compressor work? Whether the initiator is a performance anomaly.

3. Whether the compressor piston has a cylinder jam fault.

It is best to ask the after-sales service to come for maintenance.

1) Cause analysis.

1. The high-pressure output buffer pipe in the compressor is broken, or the screw fixing the pipe is loose, resulting in the high-pressure pipe not exhausting, and the low-pressure pipe not sucking air next to hail, so although the compressor is running, it is not refrigerated.

2. The refrigeration system leaks, the refrigerant runs out, although the compressor is running, there is no refrigerant evaporation and heat absorption in the system, and the temperature in the refrigerator does not drop.

3. The capillary is blocked, and the refrigerant cannot enter the evaporator to evaporate and absorb heat, and the temperature in the refrigerator does not drop.

2) Exclusion method.

1. Cut the casing, replace the buffer tube, or tighten the screws.

2. Find out the leakage part of the system first, and add refrigerant to a certain amount after passing the welding repair, pressure test and evacuation, usually according to the evaporator is full of frost or the refrigerator reaches the rated temperature.

3. The capillary tube or dryer is blocked, and the outlet is hot, so remove it to remove it! In addition, there are generally two types of household refrigerators: direct cooling and intercooling, which refers to the heat exchange between the evaporator (cooling pipe) and the freezing and refrigeration rooms to achieve the purpose of cooling; Intercooling means that the evaporator (cooling pipe) is separated from the freezing and refrigeration room, and the cold air is blown into the freezing and refrigeration room by a fan to achieve the purpose of cooling.

Whether your refrigerator is not refrigerated should be judged from the following aspects:

1: Check whether the power connection is normal.

Open the door and observe whether the light in the box is lit, or test it with an electric pen.

2: If the power connection is normal, listen to whether the compressor is working.

The compressor will emit a slight vibration motor sound when working normally (if you feel the vibration of the compressor with your hands, you should be careful not to burn, because the compressor temperature is 40-50 in winter and 80-90 in summer).

3: If the compressor can work, judge whether the refrigeration system has refrigerant (commonly known as potion).

Let the refrigerator run for a few minutes before unplugging and listen carefully for the sound of liquid running inside the copper tube. If not, it means that the refrigerant in the system has leaked, or the compressor has lost its capacity.

4: If your refrigerator belongs to the intercooled type, you should check whether the fan is working.

Open the door of the freezer, press and hold the button at the edge of the box mouth with your hand (this button controls the indoor lighting and stops the fan when the door is opened) to check whether the fan is working, the fan will not work will also cause the refrigerator to not refrigerate.

In addition, if too much food is placed in the box, it will also affect the refrigeration effect.

Hope mine can help you.

Summary. The refrigerator is suddenly not refrigerated, the lights are on, and the sides of the box are cold Hello dear! There is a thermostat inside the refrigerator, which can automatically adjust the change of the temperature inside the refrigerator, if the temperature around the refrigerator is too high, resulting in the change of the refrigerator thermostat, there will be a change in the refrigerator refrigeration, or because the temperature setting of the thermostat is too high, it is recommended to change the thermostat of the refrigerator to this top temperature.

The refrigerator suddenly stopped cooling, the lights were on, and the sides of the box were cold.

There is a thermostat inside the refrigerator, which can automatically adjust the change of the temperature inside the refrigerator, if the temperature around the refrigerator is too high, resulting in the change of the refrigerator thermostat, there will be a change in the refrigerator refrigeration, or because the temperature setting of the thermostat is too high, it is recommended to change the thermostat of the refrigerator to this top temperature.

Dirty gambling in the system or insufficient suction and exhaust of the compressor can also cause this phenomenon. Refrigerants in refrigeration systems use the process of vaporization of liquids to draw heat from the refrigerator.

Personally, I think there is a high probability that the compressor will be broken.

How much does it cost to change the compressor?

Hello dear! My suggestion is to call someone to check it first, if the compressor is broken, it is still under warranty, then it doesn't cost money.

It has been out of warranty and has been used for more than 10 years.

Hello dear! Then I don't think it's appropriate to replace the compressor with the old refrigerator, because it will break down one after another.

Because the compressor is quite expensive.

1. If it is because the compressor is faulty, the motor coil is burned out. 2. Due to long-term use, the refrigerant inside the refrigerator may be insufficient, or there may be no refrigerant. 3. There will be a thermostat inside the refrigerator, and the thermostat has been damaged, or the contact is not good, which will cause the refrigerator light to be on and not refrigerated.

Suggested solutions: 1. If it is found that the compressor has been burned, it is recommended to contact professional maintenance personnel in time for on-site inspection, and if the coil is burned out after the inspection, timely maintenance can be restored to the normal refrigeration state. 2. After the inspection by professionals, it is found that if the problem is caused by insufficient refrigerant, you only need to supplement the refrigerator with appropriate refrigerant, and then restart the refrigerator to solve the problem of the refrigerator not refrigerating.

3. There is a thermostat inside the refrigerator, which can automatically adjust the change of the temperature inside the refrigerator, if the temperature around the refrigerator is too high, resulting in the change of the refrigerator thermostat, if it is caused by this reason, you only need to reset the temperature of the thermostat of the refrigerator.

Summary. Dear, I'm glad to answer for you, when the indicator light of the refrigerator is on but the refrigerator is not cooling, there may be several possible reasons. Here are some common causes and corresponding solutions:

1.Incorrect temperature setting: Check your refrigerator's temperature setting to make sure it is set at the correct refrigeration temperature.

Some refrigerators have temperature control inside the freezer, while others are inside the freezer. 2.Power issues:

Make sure your fridge has enough power** and is functioning properly. Check that the power plug is securely connected, or you can try plugging the fridge plug into a different outlet to see if that solves the problem. If the problem persists, it may be necessary to contact a professional to check the electrical connections of your refrigerator.

3.Cooling system failure: The core part of refrigerator refrigeration is the cooling system, including compressors, condensers, evaporators, and refrigerants.

If the cooling system fails, the refrigerator will not be able to refrigerate. This can be caused by compressor failure, clogged condenser, refrigerant leakage, etc. In this case, it is necessary to contact a professional service technician for diagnosis and repair.

4.Ambient temperature is too high: If the ambient temperature around the refrigerator is too high, it may cause the refrigerator to not be able to cool effectively.

Make sure the ambient temperature around the refrigerator is within a suitable range (typically 18 to 24) and maintain adequate ventilation.

Dear, I'm glad to answer for you, when the indicator light of the refrigerator is on but the refrigerator is not cooling, there may be several possible reasons. Here are some common causes and corresponding solutions:1

Incorrect temperature setting: Check your refrigerator's temperature setting to make sure it is set at the correct refrigeration temperature. Some refrigerators are temperature-controlled inside the freezer chamber, while others are inside the freezer.

2.Power issues: Make sure your fridge has enough power** and is functioning properly.

Check that the power plug is securely connected, or you can try plugging the fridge plug into a different outlet to see if that solves the problem. If the problem persists, it may be necessary to contact a professional to check the electrical connections of your refrigerator. 3.

Cooling system failure: The core part of refrigerator refrigeration is the cooling system, including compressors, condensers, evaporators, and refrigerants. If the cooling system fails, the refrigerator will not be able to refrigerate.

This can be caused by compressor failure, blockage of the refrigerant by-condenser, refrigerant leakage, etc. In this case, it is necessary to contact a professional service technician for diagnosis and repair. 4.

Ambient temperature is too high: If the ambient temperature around the refrigerator is too high, it may cause the refrigerator to not be able to cool effectively. Make sure the ambient temperature around the refrigerator is within a suitable range (typically 18 to 24) and maintain adequate ventilation.

Dear, some refrigerators use a fan to circulate air during the refrigeration process. If the fan inside the refrigerator fails, the refrigerator may not be able to distribute the cold air evenly, resulting in a sweltering chamber that does not make silver. Check that the inside of the refrigerator is bent and the chain can hear the sound of the fan running, if not, you may need to contact a service person to repair or replace the fan.

The reason why the refrigerator is not refrigerated is due to the blockage of the evaporator pipe, the failure or failure of the compressor, the dirty condenser, the failure of the thermal control, and the leakage of refrigerant.

1. Evaporator pipe blockage: The evaporator pipe in the refrigerator may be blocked by food or other sundries, which will reduce the refrigeration effect.

2. Compressor failure or failure: The compressor in the refrigerator is an important part of the refrigeration system, if the compressor fails or fails, the refrigerator cannot be refrigerated.

3. Dirty condenser: The condenser is a heat exchanger through which the cold air flows through the refrigerator, if the surface is covered with dust or dirt, the heat dissipation effect will be weakened, resulting in the refrigerator being unable to refrigerate.

4. Thermal control failure: Thermal control is an important part of temperature control in the refrigerator, if the thermal control fails, the refrigerator will not be able to control the temperature, resulting in the inability to refrigerate.

5. Refrigerant leakage: Refrigerant is the core of refrigerator refrigeration, if the refrigerant leaks, the refrigeration effect will be reduced, resulting in the refrigerator being unable to refrigerate.

The refrigerator is not refrigerated, and the light is not defeated, the lamp is just a lighting circuit, which can only show that the refrigerator can still supply power normally. The reason why the refrigerator is not refrigerated: 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 burned out of the motor.

If the compressor of the machine is not refrigerated, 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 fluoride to see the lion.

If it is suddenly not refrigerated, it should not be a refrigerant leak, the general effect of refrigerant leakage is slowly bad, and the compressor should be started normally. It should be a control problem, change the compressor protector first. The lack of refrigerant, if it is caused by the lack of refrigerant, the performance is obvious, first of all, it will be the refrigerator that is not refrigerated, and then the evaporator of the freezer can not be frosted, and then the freezer will not be refrigerated.

The solenoid valve is not reversed: use a multimeter to check whether the solenoid valve is normal. Sensor failure:

If the variable temperature room or refrigerator room is not cooled, it is necessary to check whether the sensor parameters are normal.
