What is the reason why Samsung air conditioners are not cooling?

If the air conditioner is not cooling, you can troubleshoot it by following these steps:1Incorrect usage mode Please check the set mode:

In refrigeration mode, the "refrigeration" or snowflake sign should be displayed on the remote control or machine. If your air conditioner mode is displayed incorrectly, press the [Mode] button to adjust to the correct cooling mode. 2.

The temperature of the machine is set incorrectly (1) the setting temperature is higher than the indoor temperature When the air conditioner is using refrigeration, the refrigeration setting temperature should be more than 3 degrees lower than the ambient temperature, otherwise due to the low ambient temperature and the high temperature set by the air conditioner, there will be no refrigeration. (2) Set the temperature lower than the indoor temperature Check whether there is a cool breeze at the air outlet, if there is a cool breeze, it is recommended to clean the air conditioning filter; If there is no cool breeze at the air outlet, it is all natural wind, and it is recommended to set the air conditioner to 20 degrees for 15 minutes. 3.

The allowable voltage fluctuation range of Samsung room air conditioners is 187 253V. Unstable voltage or too low voltage will cause the external unit to fail to operate normally, which will directly affect the refrigeration effect of the air conditioner. It is recommended to contact the property electrician in the community to check the voltage situation in the home, and if the voltage is unstable or the voltage is too low, please install a voltage regulator.

4.The installation position of the outdoor unit does not have good heat dissipation or no sunshade equipment is installed, because the outdoor unit of the air conditioner is much more sensitive to climate than other electrical appliances, if the heat dissipation is not good or the external unit is exposed to direct sunlight, the compressor temperature is too high, and it is easy to increase the load of the compressor. When the compressor is refrigerated, the temperature will continue to rise, and when the external unit is exposed to sunlight for a long time during the day, the temperature of the compressor exceeds 125 degrees, and it will automatically shut down.

It is recommended to install an awning to block direct sunlight; Or when the external unit is shut down, turn off the power of the air conditioner, rinse the outdoor unit with cool water to cool down the external unit, and wait for a while before powering it on. In addition, it is necessary to check whether the outdoor unit is installed for poor heat dissipation, remove obstacles, or contact the service center to move the air conditioner for processing.

1. It may be that the lack of refrigerant causes the refrigerator not to refrigerate. 2. It may be a problem with the refrigerator power cord. 3. Frost forms in the refrigerator evaporator.

Usually, air-cooled refrigerators have only one evaporator, and when the evaporator is frosted and clogs the air duct, the cold volume cannot be released, which will cause the refrigerator to not refrigerate. 4. The contents stored in the refrigerator are too full, and there is no gap between the inner wall of the refrigerator and the food, which obstructs the air inlet and outlet or sensors, affects the circulation of cold air, and causes the refrigerator to not refrigerate. Suggested workaround:

1. If the refrigerant leaks or is insufficient, the refrigerator will not be refrigerated, and the refrigerator will use refrigerant to refrigerate, and if the refrigerant is lacking, there will be no refrigeration. Another is that due to the failure of the compressor, the compressor of the refrigerator will automatically start, resulting in the refrigerator not being refrigerated, and the freezer will not be able to frost if the refrigerant is insufficient. You can find a professional repairman to repair the loophole or refill the refrigerant.

If the compressor is also about to fail, it is recommended to open the casing and replace the buffer hanging tube. If it's not a big problem, just tighten the screws. 2. Check whether the plug is plugged in and check whether the power supply voltage used is within the range of the instruction manual.

3. Check the defrosting system of the refrigerator, it may be that the defrosting timer is faulty, or the heating tube may be burned. 4. Organize the contents of the refrigerator and try not to overstuff the refrigerator.

The air conditioner with a small number of horses is placed in a large room, and the air conditioner is not cleaned for a long time.

1. The air conditioner with a small number of horses is placed in the beam width of the large room, rather than the problem of the air conditioner itself. Of course, there is also such a problem, the room has a large window and is open. Or this can also occur when there are many heat sources in the room (such as multiple computers turned on, fluorescent lights turned on, or a glass room in the west, etc.).

Solution: First, change the conditions of the use environment. Secondly, before buying an air conditioner, you must choose a Samsung home air conditioner that matches your room.

Increase the airtightness of the use environment. In addition, reduce the heating source in the environment of air conditioning, etc., to solve the problem of non-cooling.

2. The reason why the air conditioner is not cleaned for a long time is that there is a large amount of dust and garbage on the radiator of the outdoor unit, which causes poor heat dissipation effect, and the cold and heating air conditioner caused by the old reeds does not get cold. If you do not clean and maintain the Samsung household air conditioner for a long time, it is easy to cause unclean indoor air, causing air conditioning disease, and due to poor heat dissipation, it will consume more electricity, and the life of the air conditioner will be greatly reduced.

Solution: Clean and maintain the air conditioner to make the clean outdoor unit more tolerant of late heat dissipation.

To sum up, it is nothing more than these aspects;

1. The starting capacitor of the cooling fan of the outdoor unit is damaged, the fan does not rotate, and the temperature is too high and the protection stops. It can be seen with the naked eye. If the starting capacitor is damaged, replace the fan starting capacitor.

2. If the air conditioner turns on the timing mode, the air conditioner will automatically shut down when the time reaches the predetermined time point, which is a normal phenomenon, and it is enough to restart the air conditioner.

3. If the air conditioner is in sleep mode, the remote control will automatically turn off when the temperature reaches the adjusted temperature. You can check the remote control, turn off sleep mode, and change the mode to normal mode.

4. If the freon in the air conditioner is insufficient, it will also cause the air conditioner to fail to refrigerate, and the internal temperature of the air conditioner is too high, and the air conditioner will start the self-protection function and shut down.

5. In order to make the temperature conditions in the room more suitable, many users set the temperature of the air conditioner in combination with the environmental needs, and when the air conditioner reaches the set temperature standard, the air conditioner will stop supplying air, so the air conditioner will shut down.

6. If the air conditioner is shut down during heating, it may also be caused by air conditioner defrosting. Because the air conditioner will frost due to heat exchange when it is heating, the air conditioner will automatically defrost after working for a period of time, so the air conditioner will shut down, but after the defrosting work is over, the air conditioner will resume heating.

Sometimes when we are engaged in air conditioning maintenance, if there is no sensor at hand temporarily, we can use more than 10,000 ohms of resistance to plug in the plug of the sensor to do temporary problem judgment and maintenance, and find out the problem first. This is also the application of some of the methods we usually maintain.

1. The reason why the air conditioner is not refrigerated is a stove shot: freon is not enough, also known as "refrigerant" is not enough;

This situation generally appears in the use of three to four years of old air conditioners, air conditioners are not completely not refrigerated, but the effect of refrigeration is not good enough, because the old air conditioners are using Freon as a refrigerant, and it will volatilize off after a long period of use.

2. The second reason why the air conditioner does not refrigerate: the voltage of the power supply is not enough;

The power supply voltage is unstable and often fails to reach the normal voltage, especially during the peak of electricity consumption.

3. The third reason why the air conditioner is not refrigerated: the power of the air conditioner is not enough to not refrigerate.

The reasons for this non-refrigeration include small power air-conditioning pipes and large-area rooms, and some although the air-conditioning power and the room area seem to match, but because the room is relatively unsealed, such as doors and windows are wide open, or there are heat sources in the room, such as computers, glass rooms will be exposed to the west, etc., which will lead to non-refrigeration.
