What s going on with the air conditioner not heating without wind, what s going on with the air cond

There may be several reasons why an air conditioner is not heating up:

The filter screen has dust, and it is well known that the filter screen will inevitably be stained with a lot of dust after being used for a long time, which can easily lead to the heat in the air conditioner not being discharged in time, resulting in the air conditioner not heating. It is necessary to clean the dust and foreign matter in the vent in time, if it is not cleaned in time, it will lead to a small air volume and no heating.

Solution: Clean the filter regularly to help unclog the vents so that the air conditioner can heat properly.

There is a problem with the air conditioner capillary or check valve: it resembles the human capillary, and is mainly made of capillary tubes with an outer diameter of up to 5 mm and a water supply circuit with an outer diameter of 20 mm. The check valve is mainly due to the prevention of reverse flow of oil flow and reverse flow of air.

If there is a problem with these two, the air conditioner will not be able to heat up.

Solution: Replace the capillary or check valve immediately, so that the air conditioner can heat normally.

The outdoor temperature is too low: Of course, if the outdoor temperature is too low, it will also affect the normal use of the air conditioner. Normally, if the outside temperature is too low, the indoor air conditioner will not be able to heat up, because the air conditioner will not be able to defrost in this case.

Solution: Use special appliances to clean the frost on the air conditioner, so that the heating can be normal.

Lack of fluorine in the air conditioner: If there is a lack of fluorine inside the air conditioner, it will affect the heating or cooling effect. Most of today's air conditioners are heat pump-heated air conditioners, which must use freon in order to function properly.

Solution: At this time, you need to ask a professional to fluoride the air conditioner, so as to ensure the normal operation of the air conditioner.

This answer is applicable to most brands of air conditioners such as Gree, Midea, and Haier.

After the air conditioner is heated, when there is no air response, first check whether the power supply line of the air conditioner is a path, and if the line is broken, it needs to be replaced immediately.

Secondly, whether the voltage in the home is too low, because the voltage is too low to play an obvious heating role.

It is also necessary to consider whether there is a lack of fluoride and whether the room area is too large for the air conditioner to heat significantly.

This answer is applicable to most brands of air conditioners such as Midea, Gree, Haier, etc.

The air conditioner does not heat the air, which may be due to the lack of fluoride and other reasons.

1. Lack of fluoride. This situation is the most common, the air conditioner may only be able to cool in the summer, although it is not very effective but can still cool.

But when the air conditioner needs to heat in winter, it is found that the air conditioner is too difficult to heat, and there is almost no hot air, although there may be a little hot air, but this hot air is almost minimal, in this case, the lack of fluorine in the air conditioner is one of the most common reasons, and the lack of fluorine needs to be added to solve the problem.

2. The temperature sensor is damaged.

When the temperature sensor or tube thermostat of the indoor unit of the air conditioner is damaged, there will be no air conditioning heating, and the indoor unit and outdoor unit of the air conditioner are not running, only when the air conditioner is turned on and refrigerated, it will run, generally the temperature sensor of the air conditioner is damaged, and the temperature sensor can be used as long as the temperature sensor is replaced.

3. The four-way valve is abnormal.

In this case, you may wish to check the four-way valve, the four-way valve is not opened, the four-way valve is stuck or the electronic control does not output the four-way valve voltage, and the specific problem needs to be analyzed.

4. The air conditioner is turned on too shortly.

The heating time of the air conditioner in winter is generally about 5 minutes before the hot air will come out, this is the normal air conditioning anti-cold wind function, when the air conditioner is turned on to heat up for 5 minutes, if there is no hot air, it may be a problem with the air conditioner.

5. The air conditioner filter is too dirty.

Although the air conditioner can be heated, the indoor and outdoor units of the air conditioner are not damaged, but the air conditioning filter is too dirty, and the heating of the air conditioner will be affected to a certain extent, so you need to clean the filter in time.

Features:

In winter, when the weather is cold, we need to heat to keep warm, and air conditioning is a very common form of heating. The warm air on the remote control of the air conditioner is the heating and air supply, which needs to be adjusted to the sun mode and turned on the air supply mode. The logo on the remote control of the air conditioner, the sun represents heating, the ice flower represents cooling, the water droplets represent dehumidification, and the wind page represents air supply.

The heating effect of the air conditioner is very good, the heating is fast, and the ring is clean.

The possible reasons for the lack of air conditioning heating are as follows:

1. Lack of fluoride. This situation is the most common, the air conditioner may only be refrigerated in the summer, although the effect is not very good, but it can also be refrigerated, but when the air conditioner needs to heat up in winter, there is almost no hot air, although there may be a little hot air, but this hot air is almost minimal, this situation air conditioning fluoride deficiency is one of the most common reasons, fluorine deficiency needs to be fluorinated to solve the problem.

2. The temperature sensor is damaged.

When the temperature sensor or tube thermostat of the indoor unit of the air conditioner is damaged, there will be no air conditioning heating, and the indoor unit and outdoor unit of the air conditioner are not running, only when the air conditioner is turned on and refrigerated, it will run, generally the temperature sensor of the air conditioner is damaged, and the temperature sensor can be used as long as the temperature sensor is replaced.

Determination of fluoride deficiency in air conditioners

1. After turning on the machine for more than ten minutes, open the panel of the indoor unit, and you should be able to see that the evaporator (the part of the copper pipe strung with aluminum sheets for heat exchange) is evenly covered with condensate (like dew), which is normal. If half of them are not, it may be fluoride deficient. If there is local frost or ice, it is also abnormal.

2. Users who have used the air conditioner for more than half a year can check whether there are obvious signs of oil leakage at the pipe joints of the indoor unit and the valve of the outdoor unit, if there is obvious oil leakage, it indicates that the machine has leakage, because the oil and fluorine are miscible and the oil must leak fluorine, and the fluorine leakage must leak oil.

Under normal circumstances, some models have different warm air and cold air outlets, such as Volkswagen Group cars, the front and rear ** air outlets only produce cold air by default, and the air outlets on both sides will only produce warm air.

Of course, it is also possible that the air conditioning system's blower or flap motor is faulty.

Broken heat sensor in the evaporation chamber? Mine is the same, turn on the air conditioner for more than 10 minutes and there is no wind, and the air conditioner refrigeration pipes are all ice.

There are two main reasons for the heating of the air conditioner, namely: 1. When the air conditioner is heating in winter, there should be a preheating stage when the machine is turned on, and the external machine will work first, and when the temperature of the internal machine pipe rises, the internal machine will start to supply air, which is the anti-cold air function of the air conditioner. 2. After a period of time, the external machine should be defrosted, and the internal machine will not work at that time, and the defrosting will generally take about 10 minutes.

The main reasons why the air conditioner does not heat are: 1. The reason why it takes about 8-12 minutes to "defrost" when the user turns on the air conditioner for heating is because when the outdoor temperature is lower than 0 degrees Celsius, the outdoor unit of the air conditioner will immediately frost. The room temperature may be lower, and some users mistakenly think that the heating effect of the air conditioner is not ideal.

2. Due to improper use and maintenance by users, etc. 3. The large increase in electricity consumption may cause the regional power supply voltage to be unstable or too low. 4. There may be a lack of fluorine, at this time we need to ask after-sales service personnel to check the fluoride.

Most users use heat pump type or heat pump plus auxiliary electric heating type air conditioner. 5. The applicable area of air conditioning heating is smaller than the area of the room using air conditioning, resulting in the room temperature not rising ideally, that is, the customized heat is not enough. At this time, we need to use cloth curtains and spray-painted portrait partitions to reduce the room area; -5 degrees below it is recommended not to turn on the air conditioner, use auxiliary electric heating, use wall-hung boiler or heater; When using air conditioners, we try to avoid using air conditioners during peak hours.

6. The reason why it affects the heating effect of the air conditioner is because the outdoor temperature is below -5. The lower the outdoor temperature, the worse the heating effect of the air conditioner, and the actual heating is not enough.

<> If your air conditioner is working properly in cooling and dehumidification mode, but no air is coming out in heating mode, there could be a few possible reasons: Self-ordering.

Temperature setting issues for hailstorms: Make sure you set the desired heating temperature correctly. If the temperature is set to be much higher than the current indoor temperature, the air conditioner may not start the heating mode.

Wind speed setting issues: Check your air conditioner's wind speed setting to make sure it is set at the appropriate level. If the wind speed is set to automatic, it may cause the air conditioner to not get air. Try setting the wind speed to an appropriate level, such as medium or high, to see if there is any improvement.

Incorrect mode selection: Confirm that you have selected the correct mode. Some air conditioners may have multiple mode options, such as automatic, cooling, heating, and more. Make sure you have selected the correct heating mode.

Timing Setting Issue: Check if the timing function of the air conditioner is set to make sure it doesn't automatically turn off before or after the scheduled time.

If you have ruled out the above issues but the air conditioner is still not coming out in heating mode, there may be one of the following possible causes of failure:

Fan failure: The fan inside the air conditioner may malfunction, resulting in the inability to blow hot air normally. This may require repairs or replacement of faulty fan parts.

Faulty control panel: The control panel of the air conditioner may malfunction, resulting in the heating mode not being activated correctly. This usually requires a professional repair person to inspect and fix.

Faulty sensor: The temperature sensor inside the air conditioner may be damaged or malfunctional, and it may not be able to properly sense the indoor temperature and activate the heating function. This requires a service professional to overhaul and replace the sensor.

In this case, it is recommended that you contact a professional aircon repairer or contact the customer support of the aircon manufacturer, who can troubleshoot the aircon in more detail and provide appropriate repair solutions.

Whether it is refrigeration or heating, the air conditioner needs to take a certain reaction time to produce the effect, so it may not be able to produce air within a few minutes, and it takes three to five minutes for the external unit to produce air during heating, which is the process of preheating and the process of preventing cold air.

If the air conditioner does not ventilate after waiting for a long time, it may be that the filter and condenser have not been cleaned for a long time.

If there is no wind all the time, it may be a problem with the wind wheel, remove the window machine sock cover, find the fan wheel under the air outlet, turn it by hand to see if it can be easily rotated, if it doesn't work, it means that there is something stuck inside or the motor bearing is short of oil, if it can be rotated, it may be that the capacitor is broken, it is recommended to contact professional maintenance personnel for maintenance.

The solutions for air conditioners to not heat up and not ventilate are: cleaning or replacing air conditioner filters, checking the air conditioner room slag air unit, checking the air conditioner indoor unit, etc.

1. Clean or replace the air conditioner filter.

If the empty car does not heat or ventilate, first check whether the air conditioning filter needs to be cleaned or replaced. If the filter is dirty, it will affect air circulation, you can remove the filter, rinse it with clean water, dry it and put it back on, or replace it with a new one.

2. Check the outdoor unit of the air conditioner.

If the air conditioner filter has been cleaned or replaced, but the air conditioner still does not heat or ventilate, then you need to check whether the outdoor unit of the air conditioner is working properly. You can check whether the outdoor unit has abnormal noise, whether there is leakage, whether there is refrigeration effect, etc. If the outdoor unit fails, you can contact professional maintenance personnel for maintenance.

3. Check the indoor unit of the air conditioner.

If the outdoor unit of the air conditioner has been checked, but the air conditioner still does not heat and does not produce air, then you need to check whether the indoor unit of the air conditioner is working properly. You can check whether the indoor unit has abnormal noise, whether there is water leakage, whether there is refrigeration effect, etc. If the indoor unit fails, you can also contact professional maintenance personnel for repair.

Precautions for air conditioners not to heat or ventilate:

1. Clean or replace the air conditioner filter regularly.

In order to avoid the situation that the air conditioner does not heat and does not produce air, the air conditioner filter can be cleaned or replaced regularly to ensure smooth air circulation, so as to ensure the cooling effect of the air conditioner.

2. Regularly inspect the outdoor unit and indoor unit of the air conditioner.

In order to avoid the failure of the outdoor unit and indoor unit of the air conditioner, you can regularly check the outdoor unit and indoor unit of the air conditioner to ensure their normal operation, so as to ensure the refrigeration effect of the air conditioner.

3. Choose a regular air-conditioning brand and service provider.

In order to avoid the situation that the air conditioner does not heat and does not produce air due to poor quality or poor service, we can choose a regular air conditioner brand and service provider to ensure the quality and after-sales service of the air conditioner.

<> What happens when the air conditioner does not blow the air: whether the air conditioner is refrigeration or heating, it takes a certain reaction time to produce the effect, so it may not be able to produce air within a few minutes, and it takes three to five minutes for the external unit to come out of the air after heating, if the air conditioner does not blow after waiting for a long time, it may be that the filter screen and condenser have not been cleaned for a long time.

This answer is applicable to most of the air conditioning models of brands such as Midea KFR-26GW N8MJA3 &> Gree KFR-35GW NHA1BAJ.
