Xiaoshan air conditioning maintenance What is the reason why the air conditioner is not cooling

First, it may be that the refrigerant leakage is insufficient (commonly known as "refrigerant" is not enough), and the refrigerant can be added.

Second, the power supply voltage is not enough, and the compressor cannot operate normally. It is recommended to install a voltage regulator.

3. The refrigeration power of air conditioning is small and the room area is too large; Room insulation is not effective. Take these factors into account when choosing an air conditioner.

Fourth, the external ambient temperature is too high, and the refrigeration time is longer than usual.

5. The air conditioner is not cleaned and maintained for a long time. Wash in a timely manner.

6. The copper pipe connecting the indoor unit and the outdoor unit is too long. Find a professional for commissioning.

Air Conditioner Maintenance Air Conditioner Not Refrigeration Pro, Hello! Reasons why the air conditioner does not refrigerate: 1. The biggest possibility is that the refrigerant of the air conditioner leaks.

2. The compressor is damaged and does not work. 3. The temperature difference between indoor and outdoor is too large, resulting in the air conditioner not being able to refrigerate or the refrigeration effect is very slow. 4. There is a problem with the air conditioner button, and it has no effect after pressing it, resulting in the air conditioner not being able to turn on.

5. The failure of the single cooler causes some functions to fail to start. 6. The air conditioner cannot be refrigerated due to the failure of the internal unit of the air conditioner or the main board of the air conditioner. 7. Or there is too much garbage at the air outlet of the air conditioner, resulting in the inability to supply air out in time.

8. The internal zero live wire of the air conditioner power supply is connected incorrectly. 9. The fan of the internal or external unit is damaged, resulting in frost and inability to refrigerate. 10. If there is too much refrigerant, it will affect the heat dissipation, and the refrigerant is deployed according to a certain proportion, and the heat dissipation is large, and vice versa.

If you can't see a single bubble in the sight glass** while the air conditioner is running, then there is too much refrigerant. 11. If the refrigerant is too little, it will affect the evaporator, resulting in insufficient heat absorption, and if the continuous bubbles cannot be seen from the sight glass when the air conditioner is running, then it means that the refrigerant is too much. Maintenance method:

1. The refrigerant contains other impurities, which leads to the decline of refrigerant refrigeration, so you should buy a regular and qualified refrigerant. 2. It is not good for the refrigerant to contain too much water, the desiccant is blue when it does not contain water, and the desiccant is red if there is more water, please find a professional maintenance personnel to replace the refrigerant. 3. Too much air in the refrigeration pipe is not good, which will lead to increased pressure and poor refrigerant circulation.

Drain the air out of the refrigeration pipes. 4. The drive belt of the air conditioning compressor is relaxed, resulting in the reduction of refrigerant power, and the drive belt is rotated to 90 degrees by hand, if it cannot be turned to 90 degrees, the drive belt is too tight, and if it exceeds 90 degrees, it means that the drive belt is too loose. It is necessary to find a professional maintenance personnel to replace the drive belt.

5. Let the maintenance personnel check whether the power supply voltage is too low and the suction power of the compressor electric clutch decreases, and the refrigerant cannot be used. 6. If the heat dissipation capacity of the condenser is reduced, use a soft brush to clean the dirt on the condenser. Hope it helps!

Summary. The main reason why the air conditioner will be refrigerated and will not be refrigerated for a while If the air duct of the air conditioner is installed for a long time, it may lead to the poor effect of transferring indoor heat to the outdoors, so that the refrigeration is not very obvious, it is best to find a better position to reinstall it, and strive to shorten the ventilation pipe. If the air conditioner is running normally, and everything else is in good condition, but the room does not feel the cold air, only close to the air conditioner air vent to have the air conditioner, it is likely that the horsepower of the air conditioner is too small, and the space in the room is too large, then it is best to change to an air conditioner with more horsepower.

Air Conditioner Repair The air conditioner does not refrigerate.

Hello. The air conditioner will cool down for a while, and it won't be cooled for a while, what's going on.

If the air conditioner's air duct is installed for a long time, it may lead to poor effect of indoor heat transmission to the outdoors, so that the refrigeration is not very obvious, and it is best to find a better position to reinstall it, and strive to shorten the ventilation pipe. If the air conditioner is running normally, and everything else is in good condition, but the room does not feel the cold air, and only the air conditioning can be found on the air conditioner air vent, it is likely that the horsepower of the air conditioner is too small, and the space in the room is too large, then it is best to change to an air conditioner with more horsepower.

The air conditioner will cool down for a while, and it will not be cooled for a while.

It is mainly caused by the problem of long ventilation pipes.

It is recommended to contact after-sales personnel for door-to-door inspection and maintenance, pro.

Faulty air conditioner? I'll tell you how to solve these failures, which should save you a lot of detours.

When encountering a failure of the air conditioner, we must strictly follow the scientific procedures, and do not act blindly and disassemble at will when the situation is unclear, the fault is unclear, and there are countless in the heart. The consequence of this often amplifies existing faults, increases operating costs, shortens the normal service life of equipment, and leads to early scrapping of equipment.

The press does not start, there is no problem with the temperature setting, but there is no response when the power is on? If the press does not turn the fan, you must look at the capacitor first.

The capacitor bulge needs to be replaced, and the capacitor is checked for power supply.

If there is a power supply, the overload protection of the press checker is the key.

If there is no power supply in the house, first check the connecting wires.

Secondly, it is best to look at the temperature control and replace the temperature control.

The relay is a key point, and the front drive should be judged.

If all of the above are normal, the following things will be easy to do.

Motherboard repair or replacement is subject to the user's decision.

The air conditioner is not refrigerated well or not refrigerated].

This problem is most common, and the lack of fluorine in air conditioners is the key.

When the machine is turned on, first touch the trachea and judge it by the temperature.

If it is cold, the speed of the fan may be low.

The inner tube scales and dust are cleaned or replaced.

If the inner tube is not considered cool, the thick tube may be flattened.

The return air temperature is not cool, and then touch the intake air to judge.

The air intake is cold and frosty, and fluoride is added to try again.

If the frost slowly disperses, it is a good decision to lack fluoride.

It is not difficult to see the aging of the press, and the lack of exhaust is the key.

Four-way gas is also commonly judged by fluoride collection.

High-pressure scales must be seen to be dirty, and they will be slow to refrigerate.

- Finally, I wish the work to go well, fix the air conditioner as soon as possible, and live a happy ———

There are many reasons why an air conditioner doesn't refrigerate:

1) Fluorine leakage at the connecting pipe joint;

2) There is a leakage point in the connecting pipe;

3) The wiring is incorrect;

4), fuse burning;

5) The compressor is faulty; The starter capacitor is damaged.

6) The external environment temperature is high, and the indoor personnel are more than the United States, and the air conditioner is working at full load.

7) If the power supply voltage is too low, the air conditioner is not easy to start, and it will stop or the fuse will blow after starting, so it is recommended that the user install a power regulator.

8) The air outlet of the air outlet is not large if the temperature does not drop in the strong cold block room, which is the air filter has too much dust, clean the filter.

9) The thermostat is improperly adjusted.

10) The installation position of the air conditioner is not good, which will lead to uneven indoor temperature or poor refrigeration effect, if the above cannot be determined, it will be repaired.

First of all, check whether the air conditioner is operating normally, including the indoor unit and the outdoor unit, especially the compressor of the outdoor unit, as long as one of them is not running normally, then you have to ask the master to repair it.

Then check the filter of the air conditioner, if the air conditioner starts normally, but it does not emit cold air, it is likely that the filter screen is too dusty, and it is best to spray it with that special filter cleaning agent.

Then check whether the refrigerant is insufficient, that is, the so-called freon, if it is insufficient, add freon, and check whether there is a gas leak in the cold circulation system, if there is a leak, you have to make up the leak.

If there is no above problem, the air conditioner can also operate normally, then check the operation of the air conditioner fan, if the air volume of the fan is very small, then it may be that the fan motor is old, and the fan motor should be replaced with a new one.

If the ventilation pipe of the air conditioner is installed for a long time, it may lead to a poor effect of transferring indoor heat to the outside, so that the refrigeration is not obvious, it is best to find a better location to reinstall it, and strive to minimize the ventilation pipe.

If the air conditioner is running normally, and everything else is in good condition, but the room does not feel the cold air, only close to the air conditioner air vent to have the air conditioner, it is likely that the horsepower of the air conditioner is too small, and the space in the room is too large, then it is best to change to an air conditioner with more horsepower.

If it can be turned on but not refrigerated, there should be no refrigerant, and the refrigerant may be charged differently according to the place, 80 to 100 yuan for a horse.

The pipeline is damaged without refrigerant, the compressor is damaged by the motor and valve, the temperature control switch (far infrared switch) and the power supply of the motherboard are electrified, etc.
