What should I do if the Haier air conditioner turns on the cold air and the compressor blows the col

The external fan blows cold air, which means that the compressor is working, because the external fan is tied to the compressor, that is to say, the external fan of the compressor is working. And the causes and solutions of air conditioning:

1. The compressor lacks refrigerant, add refrigerant.

2. The compressor lacks oil, so you need to add some oil to the compressor.

3. If the refrigeration system line is faulty, check the line.

4. The thermostat interface is broken, replace the thermostat.

The air conditioner compressor blows cold air. You can tune it up, there is a setting, find the adjustment in the settings. Adjust to the right temperature. If the cold air is blowing all the time, then the components need to be replaced, perhaps caused by the aging of the wiring and components.

In this case, it is likely that the compressor is malfunctioning, so be careful in this regard, as other refrigerants may be missing.

If the air conditioner blows cold air outside, the internal unit will blow hot air, and the external unit will blow hot air, and the internal unit will blow cold air.

If the compressor fault is ruled out, it is a four-way valve failure, and even if the four-way valve fails, heat exchange will be carried out.

If the air conditioner blows cold air out of the compressor's position, it means that you are in indoor heating mode. Just turn on the cooling mode and the cool breeze can come out of the house.

This is because of the installation issue.

When the air conditioner is installed, the return pipe (thick pipe) is bent, and the flow of refrigerant in the pipeline is blocked, so the air conditioner will not be refrigerated, and the wind blowing out will be the same as the wind blown by an ordinary electric fan. If the return pipe is not bent, it is likely that the valve connecting the nozzle of the external unit has forgotten to open.

Hello friends, it may be the case just when the air conditioner is turned on, after the air conditioner runs for a period of time, the outside unit will blow hot air, if your air conditioner host is working normally, there is no problem with normal cooling and heating, thank you.

In this case, if you turn on the cold air compressor, the compressor must blow cold air, the compression is very normal, if it feels incorrect, you can ask their customer service, they will tell you how to operate.

It is very likely that it is because some of the refrigerant is missing, so this situation will occur, and it must be checked, it is very likely that there is a leak in the pipeline.

Air conditioning heating will generally be cold air in the following situations: 1. The air conditioner is just started in the preheating period, and this stage is caused by cold air; 2. When the room temperature reaches the set temperature, the compressor stops working, but the indoor temperature is high, and the air-proof air standard is not reached, and the internal machine continues to supply air, and the wind at this time is room temperature; 3. The room temperature is not at the set temperature, but the air conditioner begins to defrost, and the wind is below the room temperature; 4. If the air outlet hole of the air conditioner is in a state of blowing cold air for a long time, it is likely that there is a problem with the air conditioner. Workaround:

1. It takes three minutes to turn on the air conditioner and start the heating process of the compressor, which is the control program setting and the international general standard; 2. After running for a period of time, there is cold air, one situation is the defrosting state, and the return beam checks whether the control panel has a prompt; 3. After running for a long time, if the air outlet hole of the air conditioner still excludes cold air, it is recommended to find an after-sales service to repair the leakage limb.

The reason why Haier air conditioners blow cold air when heating:

1. The outdoor ambient temperature is too low, if the outdoor ambient temperature is lower than minus 5 degrees, the heating effect of the air conditioner will be very poor, or even not heated, but if the ambient temperature is high, the power supply voltage is also normal, and there is a problem with the air conditioner.

2. The thermostat is set incorrectly or the power supply voltage is unstable or too low.

3. There is no fault in the auxiliary electric heater of the indoor unit of the air conditioner, which is caused by the decline in the performance of the temperature sensing head.

When the outdoor temperature is too low, the outdoor unit of the hanging air conditioner cannot be frosted, and the hanging air conditioner cannot heat. In addition, if the voltage is too low, it may directly affect the cooling and heating effect of the hanging air conditioner.

The main reason for the poor heating effect of many hanging air conditioners is that there is no electric auxiliary heating power to accompany the starting energy, and the situation of the old-fashioned hanging air conditioner is very prominent. The air filter of the hanging air conditioner has accumulated too much dust, and the vents of the inner and outer units are blocked by foreign objects.

The function of the filter screen is to adsorb the dust in the air, if the dust is too much and not cleaned in time, the air circulation will be blocked, resulting in the reduction of the air outlet volume, resulting in the key chaos and the heat production in the machine without a manuscript method is brought out by the flowing air in time, resulting in insufficient heat production.

1. When just heating, the internal machine is not windy, and the hot air will be blown after a certain temperature needs to be preheated, which is about the cold air of the air conditioner.

2. Take a closer look at the remote control or button of the air conditioner to see if it is pressed for heating, whether it will be pressed wrongly, and if it is wrong, you can adjust it by pressing the wrong button.

3. If the temperature is not high or the air is still cold after 15 minutes of using the air conditioner, it may be that the refrigerant inside the air conditioner is leaking, and you need to find a professional to fluoride the air conditioner.

4. Generally, the air conditioner will carry out a defrosting process during the heating process, and the internal and external machines of the air conditioner will automatically stop working during the defrosting process, and the heating function will be automatically turned on again after the defrosting is over.

5. If none of the above reasons are true, the lead can be controlled by the open circuit of the CT coil or the load is not detected, the compressor is not allowed to run or the CT current mutual sensing circuit of the computer board of the outdoor unit is broken, and the motherboard and EEPRO of the external unit need to be replaced.

Now there are many people who report that the heating effect of the air conditioner is very poor, which is a normal phenomenon and has nothing to do with the machine itself, please rest assured.

1.Does your air conditioner have electric fluorine heating? If you have one, turn on this feature.

2.This year, the weather is unusually cold, which causes the indoor temperature to be very low, so the temperature cannot be raised, and it can only reach about 12 degrees Celsius at most.

3.The air conditioner is heated by the internal machine, and the external unit will be refrigerated, so the external unit will often frost, and the air conditioner has the function of automatic defrosting. So don't worry about the smoke coming out of something burned.

During the defrosting process, the air conditioner stops working, so the indoor temperature decreases again.

4.As you know, this year's weather is the coldest in 50 years, so please understand if the temperature does not reach it.

Two scenarios:

If the heating can be normal for about 50 minutes, and there is a "cold air" for about 6 minutes, it means that the air conditioner is defrosting, which is a normal phenomenon.

If the phenomenon you describe occurs within a short period of time during the heating cycle, it is most likely that the amount of cooling in the air conditioning system is insufficient, causing the air conditioner to malfunction and shut down.

Thank you for asking questions.

It may be caused by insufficient refrigerant. For specific reasons, please call after-sales **4006 999 999, and professional after-sales personnel will come to investigate.

You are welcome to ask the company questions again.

This is a sign of bad refrigeration, no way, it's been too cold lately and it will be fine for a few days.

Hello! The heating effect of air conditioning in winter is poor, mainly due to the following reasons:

1. The temperature setting is unreasonable, it is recommended to set it at 30 degrees, use a breeze, the room should be closed, and the window should be opened for ventilation appropriately.

2. The inner filter screen and the condenser of the outer unit are too dirty, which affects the heating effect and can be cleaned.

3. The system pressure is low, and if the normal heating pressure is lower than this standard, the heating effect will be poor, so it is recommended to add fluoride in an appropriate amount.

4. It is difficult for the air conditioner to work in an environment with low ambient temperature.

It is recommended to clean up and adjust it yourself, if it still can't be used normally, you can contact the manufacturer after-sales door-to-door inspection, I hope mine can help you!

If it's useful, give it a good review o( o

Adjust the heating mode. If the refrigerant is properly missing. It is normal for the air inlet and outlet to differ by 15 degrees.

The air conditioner will be defrosted in winter, and the machine will not be blown when defrosting.

There is a heater switch, just switch it and you're good to go.

Press the reset button and reset again.
