BYD F3, a new car, is only 3000 kilometers, why is the air conditioner not cooling?

1. Check the air conditioning filter, the air conditioning filter is too dirty, which will lead to a small air volume of the air conditioner and increase the air pollution in the car.

2. If the air volume of your air conditioner suddenly decreases after being turned on for a period of time, which is caused by the freezing of the evaporation box, just turn the temperature higher.

3. If the air conditioner is working normally, but it always feels that the refrigeration is not as strong as before, you need to rinse the condenser plate with clean water, too much dust will affect the heat exchange efficiency of the air conditioning system, thus affecting the quality effect.

4. If the air conditioning and refrigeration system is started, the two cooling electronic fans run at the same time. However, if the air conditioning pump does not engage, and of course the air conditioner does not refrigerate at all, it is likely to be a car computer failure.

5. If the idle speed of the vehicle is too low, it will also cause the air conditioning pump to be repeatedly engaged or not working, because the engine computer needs to run the air conditioning pump under the premise of ensuring driving safety. This kind of problem can be judged by lightly pressing the accelerator and observing the working condition of the air conditioning pump.

6. If the above problems are eliminated, it is basically impossible for the owner of such a fault to repair by himself, and he needs to go to the repair shop to deal with it.

The initial testing steps are as follows: Turn on the AC button first and then turn on the air conditioner. Observe whether the electromagnet clutch on the compressor is engaged, if the pressure gauge is installed on the thick pipe for suction, increase the throttle and observe whether the low pressure is about 2kg, which is less refrigerant or the compressor is broken.

If the effect is not very good at about two kilograms, please clean the car water tank and indoor air conditioning filter. If it does not suction then measure whether the solenoid coil has a resistance value. If there is, then there is a problem with the control line and it needs to be repaired in a repair shop.

Hello, is this check that the refrigerant is leaking? If my answer is helpful to you, please set it to.

Pro: There may be a problem with the compressor or the mode is not set correctly. Thank you.

See if the air conditioner filter is dirty.

The reasons why the air conditioner does not refrigerate after a few hours of BYD F3: 1. The air conditioner condenser is blocked; 2. The air conditioner filter is blocked; 3. The refrigerant of the air conditioner is not enough; 4. The compressor of the air conditioner is broken or the compressor clutch is broken.

There are generally three main reasons why the BYD F3 air conditioner is not refrigerated: the first is that the filter element of the air conditioner becomes dirty, the second is because the cooling fan of the vehicle is not rotating normally, and the third is caused by the blockage of the low-pressure system of the air conditioner.

BYD F3 air conditioner is not refrigerated from three places to check and maintain: first, check whether the vehicle's water tank and condenser are too dirty, which affects its heat dissipation, which has a great impact on the refrigeration effect of air conditioning, and can consider whether the vehicle's heat dissipation system has been cleaned.

Second, the air conditioning filter is used to block dust from outside the car from entering the car, and after long-term use, the air conditioning filter will appear stolen, odorous, and even blocked. When the air conditioner filter is blocked with dust and foreign matter, it will seriously affect the air volume of the air conditioner, and the cold air blown out will be reduced a lot, affecting the refrigeration effect.

Third, the blower is faulty or damaged. The blower is the power source of the air conditioner, and if it has a problem, the air conditioner will not ventilate. As for whether the blower is damaged or not, after the owners of the car hall turn on the air conditioner and turn on the maximum wind, they can listen to the location of the blower installed in the vehicle, whether there is work in it, or the sound of something stuck in the blower.

If your BYD F3 air conditioner isn't cold enough, there could be several reasons:

1.Fluorine leakage in the air conditioning system: Freon, the refrigerant in the air conditioning system, may leak, which can lead to poor cooling effect of the air conditioner.

2.Cabin air filter blockage: The cabin air filter can be clogged with dust and dirt, resulting in insufficient air flow and affecting cooling effectiveness.

3.Air Conditioner Compressor Failure: An air conditioner compressor may malfunction, resulting in poor refrigeration.

4.Air conditioner condenser failure: The air conditioner condenser may malfunction, resulting in poor refrigeration.

Workaround:1Check whether the air-conditioning system is leaking fluoride, and if there is fluorine leakage, you need to find a professional technician for maintenance.

2.Replace the cabin air filter regularly to keep the air flow flowing.

3.If the air conditioner compressor fails, you need to find a professional technician for repair or replacement.

4.If the air conditioner condenser fails, you need to find a professional technician to repair or replace it.

Summary. Hello, master, in this case, the first thing you need to check is whether the air conditioner refrigerant is normal. Check the pressure of the air conditioner, the low pressure is around 30 40, the high pressure is 120 150, and use the high-pressure water gun to flush the condenser of the air conditioner.

If it is too dirty, it will cause the air conditioning system to dissipate heat poorly, and use the diagnostic computer to read whether the request signal of the air conditioner pressure sensor is on when the AC is turned on. Check whether the air conditioner tank fan is working properly? In this case, if you repair and deal with it, it will be about 3 400 yuan, and there may be differences in each place**.

Check the pressure of the air conditioner, the low pressure is around 30 40, the high pressure is 120 150, and use the high-pressure water gun to flush the condensation gear of the air conditioner. If the bureau is too dirty, it will cause the air conditioning system to dissipate heat poorly, and use the diagnostic computer to read whether the request signal of the air conditioning pressure sensor is turned on when the AC is turned on.

Is it that the compressor is in bad contact, I let the repairman see it, and he said that the plug is not good, and it is good after replugging and unplugging, and then it is not good.

In this case, check the pressure and whether the tank fan is running properly when the air conditioner is not working.

Manual air conditioner, disassemble the air conditioner panel, check whether the wind direction adjustment cable is broken or disengaged. Disassemble the instrument panel to check the wind direction adjustment cable, automatic air conditioning check whether the sensor is invalid, regardless of manual or automatic air conditioning, if adjusted to the gear of the glass blowing, except for the wind of the blowing glass stool, the other tuyeres are very small, if you adjust to the glass blowing and floor block, these two tuyeres are not much different from other tuyeres without wind.

The knob of the BYD G3 warm air conversion is broken

Check whether it is a switch problem or a wire problem, disassemble the panel and take out the linear key from the panel, see if you can pull it can be pulled is the panel switch problem, check whether the line is bent or caught by something if you can't pull it, repair the car air conditioner manually to see if there is a foreign body stuck, or it may be that the lubrication is not good, you can add some lubricating oil, or there is a problem with the adjusting plate, you need to detect and replace the adjusting plate. Good way to use the air conditioner.

After the car has been exposed to the sun, just into the car, you should first open the window for ventilation, and open the external circulation, the hot air is basically discharged and wait for the temperature in the compartment to be reduced, and then replace it with the internal circulation, the car air conditioner should close the window in the process of use, if the closure is not strict, it will play the refrigeration and heating function of the air conditioner, and it is also quite fuel-intensive, as far as possible to prevent the air conditioning from being turned on for a long time, which will cause loss to the refrigeration system.

Hello, I am your exclusive technician, file rough Chang with a heart, careful, concentrate on answering your car questions, for you to find the corresponding problem solutions and solutions! First, the air conditioner is not refrigerated, first check whether the refrigerant pressure is normal, and whether the engine system and instrument system have fault codes. Second, check the water temperature sensor data, the external temperature sensor data stream, whether it is normal, if it is normal, turn on the air conditioner to check whether the compressor plug voltage is normal, if normal, the stool family check the compressor, if it is not normal, check whether the compressor circuit is short circuit or open circuit, and whether the compressor relay is connected or corroded.
