The maintenance of fixed-frequency air conditioners is mainly divided into three functional modules: 1. Inspection and maintenance of electronic control system; 2. Inspection and maintenance of refrigeration system; 3. Detection and maintenance of installation faults;
Inspection and maintenance of electronic control system: it is divided into monitoring and maintenance of indoor side electric control board and electrical parts; Monitoring and maintenance of outdoor electrical components.
Monitoring and maintenance of refrigeration system: it is divided into monitoring and maintenance of shut-off valves, heat exchangers, connecting pipelines, four-way valves, compressors, capillaries, refrigerants, etc.;
Monitoring and maintenance of installation faults: divided into abnormal faults caused by assembly, installation and maintenance factors such as noise, water leakage, and wind deflector jitter;
Necessary maintenance tools;
Basic knowledge of air conditioning;
basic operational skills;
Cleaning the air conditioner is actually very simple, go to the supermarket and buy a bottle of air conditioner disinfectant, and you can do it yourself! First remove the filter, rinse it with water, then spray the disinfectant evenly on the heat sink for disinfection, and finally install the filter and turn on the refrigeration mode......I use Jia'an at home, the effect is very good, and the sprinkler head is also very good. You can also clean the air conditioner yourself
The maintenance of the air conditioner includes the maintenance during the service life and the maintenance during the shutdown period. The main maintenance during the use period is as follows: 1. Clean the filter regularly, generally once every two weeks, and more frequently in dusty areas.
If the air conditioner is equipped with deodorization and dust removal filters, it should be cleaned and replaced regularly according to the instructions in the manual; 2. If the voltage in the area is unstable for a long time (manifested as difficulty in starting the fluorescent lamp, slower fan speed, etc.), it will affect the normal use and life of the air conditioner, and the user should better configure the voltage regulator by himself; 3. There should be no heat source near the internal unit of the air conditioner, otherwise it will affect the performance of the air conditioner, and the plastic parts of the internal unit will be deformed, which will not only affect the appearance but also increase the noise; 4. For dust removal on the surface of the air conditioner, the power supply should be cut off first, and then wiped with a dry cloth, and it should not be washed with water. The maintenance during the shutdown period mainly includes the following points: 1. Before long-term shutdown, the ventilation shield should be opened to dry the moisture in the indoor unit; 2 Unplug the power supply and remove the battery in the remote control; 3. If possible, cover the inner and outer units with a cover to keep the indoor and outdoor heat exchangers clean.
Before the season of use, the air conditioner should be inspected. First of all, remove the covers on the internal and external units, remove the obstacles on the indoor and outdoor air inlets and outlets, then install the remote control battery, turn on the power of the air conditioner, and observe whether the air conditioner is running normally after turning on the machine.

Hello, the above questions will be answered by me. There are several reasons why the freezer in the middle of the refrigerator is not refrigerated, which will lead to: 1. The power supply is not connected
Normally, the refrigerator power supply in your home is connected, but there will be some accidents that can cause the plug to not be properly connected and the power not to turn on. At this point, the freezer compartment of the refrigerator will not be cooled. It is necessary to check if the light in the refrigerator is on to determine if the power of the refrigerator is turned on.
2. The voltage is too low: If the voltage is too low, it will affect the function of the refrigerator. Usually, the voltage of the refrigerator is 187 volts.
The compressor of the refrigerator below 187 volts cannot be effectively leaked and started normally, and the cooling effect is naturally not good. 3. Low ambient temperature: The ambient temperature also affects the refrigeration of the refrigerator.
When the ambient temperature is lower than the normal starting temperature of the temperature controller, the refrigerator's thermostat will not start properly. The temperature can only be maintained when the cryogenic switch is turned on. The controller is forced to start.
4. The set temperature of the refrigerator is not reached: The temperature of the refrigerator is determined by the refrigerator thermostat, so if the temperature of the refrigerator does not meet the set requirements, it will not be shut down, and the freezer may cause the refrigerant to limit the cooling temperature. It is also impossible to rule out that the air returns to Changchang or the cooling fan is broken, and too many items in the refrigerator will block the air outlet, resulting in poor cooling effect.
5. Refrigeration system leakage: A leak in the refrigeration system means a leak in the refrigerant. Although the refrigerator is still running, there is no refrigerant in the system and it cannot absorb heat through evaporation, so the temperature of the refrigerator in the refrigerator does not decrease.
6. There are many items in the refrigerator: There are many items in the refrigerator, and the refrigeration temperature is not set enough, which will make the refrigerator in the refrigerator not cool. At this time, the temperature of the refrigerator should be turned down.
Note that the higher the temperature controller, the lower the temperature, the higher the number in summer and the lower the number in winter. 7. Compressor problem: The problem of the compressor in the refrigerator will also cause the freezer compartment of the refrigerator to not cool.
Check if the compressor pressure is too high. If it's too low, there will be problems with the compressor. 8. The fan does not work:
If the fan is not working, the cold air will not enter the cold room, and the cold room will naturally not be cooled. If the fan is damaged, it needs to be replaced in time. Hope it helps!

1. This situation may be caused by a problem with the power supply circuit. 2. It is also possible that the compressor of the refrigerator cannot work normally with dry reeds, resulting in the freezer room of the refrigerator not being refrigerated. 3. The capillary of the refrigerator is clogged, which will lead to refrigerant.
Cannot enter the evaporator normally.
Evaporation and heat absorption will also lead to the problem of non-refrigeration in the freezer compartment of the refrigerator. 4. There is also a situation that the refrigeration system of the refrigerator leaks, resulting in no refrigerant in the refrigerator, and this problem will also occur. Suggested workaround:
1. First of all, check whether there is a problem with the power circuit, if there is a problem with the power circuit, you need to contact a professional maintenance personnel to replace the circuit, or replace a new socket to try. 2. Check whether the compressor of the refrigerator can work normally, the compressor will have a buzzing sound when the compressor works normally, if there is no sound, then the compressor is faulty, at this time, you need to contact professional maintenance personnel to come to the door for maintenance, or directly replace the new compressor. 3. Check whether the capillary of the refrigerator is blocked, if the capillary is blocked, you need to contact professional maintenance personnel to dredge the pipe, and after dredging the capillary, you can solve the problem of the refrigerator freezer not being refrigerated.

Hello dear, happy to answer for you; There are three reasons why the refrigerator is not frozen in soft freezing: 1. Check the compressor of the refrigerator to see if the compressor is faulty 2. See if the refrigerator is blocked by ice, if so, that is, the defroster in the refrigerator room is bad, and you can change it with a smile 3. If the above two are suitable, check the thermostat of the refrigerator to see if it is faulty, resulting in inaccurate temperature control, so the soft freezing effect is not good.
<> 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. >>>More
What to do if the refrigerator does not refrigerate: first, check the power supply, open the door, check whether the light is on, or test with an electric pen to see if the socket is energized. Second, check the compressor, if the power connection is normal, listen to whether the compressor is working. >>>More
1. Power supply problems.
Sometimes it's not a problem with use, it's not a problem with the quality of the refrigerator, it may be a problem with the power supply, and the power supply checks if the power connection is normal. Open the door and observe whether the light in the box is lit, or use an electric pen. >>>More
