There are six reasons why an air conditioner does not heat up

One of the maintenance of the air conditioner not heating: there is a problem with the capillary or check valve of the air conditioner.

The capillary network is a simulated capillary mechanism of the human body, which is mainly divided into capillaries with an outer diameter and a water supply circuit with an outer diameter of 20mm.

The check valve is used to prevent the reverse flow of oil and also prevents the reverse flow of air. If there is a problem with both, it will cause the air conditioner to not heat up.

Solution: Replace the capillary or check valve in time, so that the air conditioner can be heated again.

Air conditioner does not heat maintenance two: the outdoor temperature is too low.

Generally speaking, if the outdoor temperature is below zero, then the indoor air conditioner will not be able to heat normally, because in this case, the air conditioner cannot be defrosted, so the air conditioner cannot be cooled.

Solution: Manually use tools to clean the frost on the air conditioner, so that the air conditioner can be heated.

The third maintenance of the air conditioner does not make heat: the four-way valve of the air conditioner is leaking.

The four-way valve is a control valve with four oil ports, which is an indispensable part of the air conditioning system, so if the four-way valve leaks, then it will cause the air conditioner to be unable to heat and cool.

Solution: Replace the four-way valve to solve the problem of air conditioning not heating.

The air conditioner does not heat the maintenance four: the filter screen has dust.

After a long time of use, the filter will accumulate a lot of dust, which will cause the heat in the air conditioner to be unable to be brought out in time, resulting in the air conditioner can not be heated, and the internal and external vents of the filter screen will be blocked by dust and foreign matter in the process of long-term use, if it is not cleaned in time, then it will lead to less and less air outlet, resulting in the air conditioner can not heat.

Solution: Clean the filter of the air conditioner regularly, so that the vents can be dredged, so that the heating of the air conditioner is normal.

Air conditioner does not heat maintenance No. 5: Lack of fluorine in the air conditioner.

There is no freon inside the air conditioner, it can not be refrigerated, the same way, there is no freon will also affect the heating effect, now most of the air conditioners are heat pump heating air conditioners, this air conditioner is the use of freon evaporation for the normal operation of the air conditioner, if there is no freon, it will cause the air conditioner to be unable to absorb heat normally, and there is no way to work normally.

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

Air conditioner non-heating maintenance six: the applicable area of air conditioning heating is smaller than the area of the room using air conditioning.

Solution: Separate the room area so that the room area matches the heating area of the air conditioner, so that the air conditioner can heat normally.

The so-called glorious years are not the days that will shine later, but the paranoia of your dreams when no one cares.

Take dreams as horses and live up to your time.

In winter, many homes use air conditioners to keep them warm. But many of them find that their air conditioners are not heating, and they can cool down in the summer before, so why is there no heating now, so what is the reason?

What is the reason why the air conditioner does not heat up:

1.There is no heating function.

The common air conditioners on the market have single cold and hot and cold air conditioners, if your own air conditioner does not heat, you can first figure out whether it is single cold or hot and cold, if it is a single cold air conditioner, it is not possible to heat.

2.Lack of freon.

Freon is the refrigerant of air conditioning, it is not only used in cooling, but also needs it to heat normally. If the refrigeration does not heat, it may be that the freon has been consumed almost before, because the demand for freon is greater for heating, so the heating work can be better started.

3.The defrosting work was not completed.

When the air conditioner heats up in winter, due to the low outdoor temperature, it takes a while to do the defrosting work when it is turned on, and sometimes it takes up to ten or twenty minutes to complete. When it is not finished, there will be no heating spray, so it will make people think that it will not be able to heat up.

4.Four-way solenoid valve failure.

If the air conditioner does not heat up, it is possible that the four-way solenoid valve is damaged or cannot enter the working state normally, which will cause the air conditioner to fail to heat. The failure of the four-way solenoid valve is generally not solved by the individual, and a professional master is needed to repair or replace the new four-way solenoid valve.

There are six reasons why an air conditioner is not heating:

1. The internal capillary network is damaged, and the check valve is broken, resulting in reverse flow of oil and air. 2. The outside temperature is too low to cause it to be unable to operate. Repentance J 3, the four oil port control valve seal is not good, resulting in air leakage.

4. There is dust on the filter screen, which makes the hot gas unable to circulate. 5. The lack of fluorine in the machine makes the machine unable to absorb heat. 6. If the voltage is too low, the machine will be turned on but the temperature will not go up.

What is the solution for the air conditioner not heating:

1. If it is caused by internal components that cannot be used, the components can be replaced, but they are generally disassembled, so after-sales help should be requested, and the power should be cut off before replacing. Here you can focus on capillary tubes, check valves, and four-way valves.

2. If it is caused by the outdoor temperature, then you need to start with the external unit and clean up the frost on the external machine. Under normal circumstances, the use of air conditioners at too low temperatures will cause greater damage to it.

3. In addition, if it is caused by dust accumulation, then do a good job of cleaning, and voltage instability should be done to stabilize the voltage, such as installing electric auxiliary heating elements.

How to maintain the air conditioner:

1. Do a good job of cleaning, the inner machine is mainly the filter core, which can be disassembled, first removed with a brush and then rinsed with water, and then installed back after drying. The external unit is mainly cleaned with dust on the shell and chassis and the fan, and the fan can be soft-brushed with a vacuum cleaner.

2. Avoid exposure to the sun, especially outside the machine. It can be used as a shelter, but it can't be used to ventilate the blue, and the damage to the machine is also relatively large due to wind and rain.

Here are six common reasons why six air conditioners don't heat:1Wrong temperature setting:

Please make sure that the temperature of the air conditioner is set correctly for heating operation. If the set temperature is too low or the heating mode is turned off, the air conditioner will not heat up. 2.

Power issue: Check whether the air conditioner is connected to the power supply and make sure the power cord is connected properly. Also make sure that there are no fuses or trippers triggered in the circuit.

3.Thermostat Pattern Masking: The thermostat is one of the key components that control the operation of the air conditioner.

If the thermostat is damaged or malfunctions, it may cause the air conditioner to fail to heat up. Check the settings and status of your thermostat and consider replacing or repairing it. 4.

Clogged air filter: A clogged air filter can restrict air flow and affect the heating effect of the air conditioner. Cleaning or replacing your air filter regularly can improve your air conditioner's heating performance.

5.Compressor problem: Compressor is one of the key components of air conditioning heating.

If the compressor is damaged or malfunctions, the air conditioner may not heat properly. In this case, a professional technician is required to inspect and repair it. 6.

Refrigerant problem: Proper refrigerant circulation is required for air conditioning heating. If the amount of refrigerant is insufficient or there is a leak, the heating efficiency of the air conditioner will be affected.

Specialized technicians are required to inspect the refrigerant system and make the necessary repairs and additions.

Summary. 1.Insufficient levels of refrigerants (e.g. freon) inside the air conditioner; 2.

Failure of the compressor inside the air conditioner refrigeration; 3.Condenser failure of the air conditioning system; 4.Evaporator failure of the air conditioning system; 5.

The control unit of the air conditioning system is faulty.

1.The amount of refrigerant (such as freon) in the interior of the air conditioner is insufficient; 2.Failure of the compressor inside the air conditioner refrigeration macro dust stove; 3.

Condenser failure of the air conditioning system; 4.Evaporator failure of the air conditioning system; 5.The control unit of the air conditioning system is faulty.

Can you tell us more about that?

1. Power supply voltage problem: air conditioning refrigeration does not heat, often due to the power supply voltage is too low, such problems, you need to check whether the power supply voltage connected to the air conditioner meets the requirements. 2. Failure of air conditioning control panel:

The failure of the air conditioning control board will also cause the air conditioner to only cool and not heat, at this time, it is necessary to check whether the circuit board is damaged, such as the smile ruler needs to replace the control board. 3. There is water in the hot water tank: there is water in the hot water box, which will cause the heating function to be unable to be used normally, at this time, the water needs to be discharged, and check whether the water pipe is connected normally, if the connection is normal, you can determine the failure of the air conditioning control board.

Summary. Hello dear, glad to answer for you! The reasons why air conditioners do not heat up refrigeration are:

1. The air filter of the air conditioner has too much dust. 2. The refrigerant of the air conditioner is insufficient, which leads to the decline of heat exchange efficiency, and the air conditioner will not heat if the heat is insufficient. 3. The defrosting controller of the air conditioner fails, so that the air conditioner does not turn into the defrosting operation state in time, which affects the heating effect of the air conditioner, resulting in the air conditioner being unable to heat <>

Hello dear, glad to answer for you! The reasons why the air conditioner does not heat up are: 1. The air filter screen of the air envy crack is too dusty.

2. The refrigerant of the air conditioner is insufficient, which leads to the decline of heat exchange efficiency, and the air conditioner will not heat if the heat is insufficient. 3. The defrosting controller of the air source is out of order, so that the air conditioner does not turn into the defrosting operation state in time, which affects the heating effect <>of the air conditioner, resulting in the air conditioner being unable to make the air conditioner hot

There is another reason: four-way valve or Qingchuan regret blue air, because the heat pump type air conditioner switches the cooling and heating state through the four-way valve. If the four-way valve is crossed, some of the refrigerant that should be involved in heat exchange will be returned directly from the compressor outlet pipe to the return pipe at the four-way valve, resulting in a decrease in the refrigerant participating in the heat exchange, and a decrease in the heat exchange efficiency, resulting in <>insufficient heat production

Pro, the refrigeration of air conditioners does not heat for the following reasons: 1. The design of the air conditioner itself. Generally, there are two modes of air conditioning: refrigeration and heating, but the energy consumption of the heating mode is much higher than that of the refrigeration mode, which is also the reason why the air conditioner does not heat the refrigeration.

2. The reason for the compressor. The compressor of the air conditioner is mostly a one-way compressor, which can only achieve the refrigeration effect, but it cannot realize the heating effect, so the air conditioner does not heat the limb. 3. The reason for the ambient temperature.

The general ambient temperature has a certain difference between the outdoor temperature and the indoor temperature, and the heating effect of the air conditioner is achieved by transferring the heat from the outside to the indoor, but if the outdoor temperature is lower than the indoor temperature, then the heating effect cannot be realized, so the air conditioning refrigeration does not heat.
