The reason why the indoor air conditioner does not heat up, the solution to the indoor air condition

When the outdoor temperature is lower than 0 degrees Celsius, the outdoor unit of the air conditioner will immediately frost, and when the user turns on the air conditioner for heating, it takes about 8-12 minutes to "defrost", 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 reason why the air conditioner cannot work normally is because the power consumption increases greatly, which 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; Open your fluoride port, use a screwdriver to push it up, and see if there is any fluorine coming out, if not, it is the protection caused by your compressor running in a state of lack of f! Hello! There are four main reasons for such problems:

1. The temperature you set is too high, and the air conditioner is shut down frequently, causing you to feel that the refrigeration effect will be good for a while, and bad for a while! This is not a fault, please don't worry, just turn the temperature down. 2. Your outdoor unit is caused by poor heat dissipation, and the compressor of the air conditioner is easy to overheat when it works under the condition of poor heat dissipation for a long time.

3. Your power supply voltage is too low, causing your air conditioning compressor to not start normally, for such a situation, you can install a voltage regulator to solve it! 4. If your compressor cannot be started, it may be a problem with the compressor or compressor capacitance, it is recommended to find a professional to check it for you.

As we all know, air conditioning is a necessary household appliance in our daily life, but after being used for a long time, there will be some minor problems, such as not heating. So what is the reason why the air conditioner is not heating? 

1. The current used by the air conditioner compressor is too large, which causes the overload protector to cut off the power supply, and eventually causes the air conditioner to fail to operate, so that the air conditioner does not respond when it is turned on and does not heat.

2. The refrigerant in the internal refrigeration system of the air conditioner is insufficient, resulting in the air pressure of the air conditioning compressor being too low, and finally the compressor cannot operate, resulting in the air conditioner not heating.

3. If the condensation pressure is too high, the compressor may not work properly, resulting in the air conditioner being unable to operate and heating normally.

4. The temperature of the air conditioner is reasonable, if the setting is relatively high, when the air conditioner is turned on, the room temperature is not set to the upper line value. As a result, the air conditioner compressor cannot start normally.

5. When the air conditioner is started, the voltage required is too low, and when the voltage is less than 10% of the normal voltage of the single phase or below 198V, it is difficult for the refrigeration compressor in the air conditioner to start. The above is the introduction of what is the reason why the air conditioner does not heat, I hope it will help you.

What should I do if the air conditioner is turned on and it is not warm?

There may be several factors for an air conditioner not heating up:

1. There is too much dust on the air conditioner, which affects the heating of the air conditioner. Cleaning inspections are possible.

2. There is a lack of fluorine in the air conditioner, so you can ask a professional to come to the door at this time and add freon to socks.

3. The ambient temperature is lower than minus 15 degrees, and the cold and heating are invalid. If there is electric heating, it can still be used.

4. The current used by the air conditioning compressor is too large, which leads to the cutting off of the power supply by the overload protector, which ultimately leads to the failure of the air conditioner to operate, so that the air conditioner does not respond when it is turned on and does not heat; Check the overload protector and have it repaired by a professional.

5. If the condensation pressure is too high, the compressor can not work properly, resulting in the air conditioner not being able to run and heating normally, you can contact the master to solve it.

The reason why the air conditioner does not heat: Qingxin.

1. There is too much dust in the air filter, the dust and scale of the evaporator and condenser are too thick, and the heating agent leaks.

2. The vents of the internal and external units are blocked by foreign objects.

3. The set temperature is too high during heating, and the set temperature is too low during heating.

4. If the ambient temperature is high during heating, the energy efficiency ratio of the air conditioner will be reduced, and if the ambient temperature is too low during heating, the energy efficiency ratio of the air conditioner will also be reduced.

Precautions for the use of air conditioners:

1. Ventilation is required before opening the leakage base air conditioner, and when the air conditioner is running, the doors and windows should be closed so as not to affect the refrigeration effect.

2. Do not blow the air conditioner directly on people, and the air conditioner should not be used for too long.

3. Do not use the air conditioner in a place with too much dust, which may cause the user to suffer from respiratory diseases.

4. When using the air conditioner, it is necessary to disinfect the air conditioner filter frequently.

5. When using the air conditioner, pay attention to the temperature difference between indoor and outdoor, and it is best not to smoke in the air-conditioned room.

Hello dear, according to the situation you described, first, the reason why the air conditioner does not heat - the lack of fluorine in the air conditioner Everyone knows that freon is the main driving force for the operation of the air conditioner, which is also the main reason for the lack of heating. Now most of the air conditioners in Xuzhi are heat pump heating air conditioners, which use the evaporation of freon for the normal operation of air conditioning. Processing*:

It is necessary for our professional staff to fluoride the air conditioner so that it can be restored to normal operation. Second, the reason why the air conditioner does not heat - air conditioning four-way valve leakage There is an important component in the air conditioner is the four-way valve, which is an indispensable part of the air conditioning system. Processing*:

Even replacing the four-way valve can solve the problem. Generally speaking, if the outdoor temperature is below zero, it will cause the air conditioner to be unable to heat normally, because in this environment, the air conditioner cannot carry out normal defrosting treatment, so it causes the air conditioner to be unable to refrigerate. Processing*:

You need to use tools to clean up the frost on the air conditioner, and you can resume work after cleaning it up.

Hello dear! Reasons why the air conditioner does not heat: 1. The defrosting controller fails to cause the air conditioner to not heat.

2. Due to the leakage of the refrigeration system, the refrigerant involved in the thermal cycle in the system is lacking, resulting in the lack of heat production. 3. If the four-way valve is gas-flowing, the refrigerant participating in the heat exchange will be reduced, and the heat exchange efficiency will be reduced. I hope to help you.

Summary. Hello, I am happy to serve you and give you the following answers: 1.

You are happy to serve you and give you the following answers: 1. The air conditioner does not heat up due to the failure of the temperature sensor in the interior or hidden part of the air conditioner, resulting in the air conditioner being unable to control the indoor temperature normally; 2. The heating system of the air conditioner may fail, resulting in the air conditioner being unable to heat normally; 3. The power supply of the air conditioner may fail, resulting in the air conditioner not working normally; 4. The filter screen of the air conditioner may be blocked, resulting in the air conditioner being unable to heat normally; 5. The heating system of the air conditioner may be out.

I'm sorry I don't understand, but can you elaborate on that?

You are happy to serve you and give you the following answers: 1. The air conditioner does not heat up due to the failure of the temperature sensor in the interior or hidden part of the air conditioner, resulting in the air conditioner being unable to control the indoor temperature normally; 2. The heating system of the air conditioner may fail, resulting in the air conditioner being unable to heat normally; 3. The power supply of the air conditioner may fail, resulting in the air conditioner not working normally; 4. The filter screen of the air conditioner may be blocked, resulting in the air conditioner being unable to heat normally; 5. The heating system of the air conditioner may be out.

1. The ambient temperature is low, and it is in the preheating period of the air conditioner, so it takes a period of time to preheat it.

Solution: Work for a period of time, warm up for a period of time to work normally.

2. Insufficient refrigerant means lack of fluorine and poor heating effect.

Solution: Leak detection of air conditioning system pipelines, and fill leakage points. At the same time, check whether there is any abnormal condition of the temperature sensor of the indoor coil unit, and supplement fluorine.

3. There is too much dust and the heating effect is poor.

Solution: Remove dust and clean pipes.

The outdoor temperature is too low, and the general outdoor temperature is generally below minus 15 degrees, which will cause the air conditioner to not heat. The air conditioner lacks fluorine, and less fluorine will lead to a decrease in the heating effect of the air conditioner. The size of the room is too large, and the power of the air conditioner is not large enough, which will also cause the air conditioner to not make heat.

Dust accumulation in the filter will block air circulation, and hot air will not be able to escape. Suggested treatment: 1. The defrosting function of the air conditioner cannot operate normally in a low temperature environment, and the frost accumulation of the air conditioner can be manually cleaned, but the ice must not be defrosted with hot water, which will damage the machine twice.

2. The air conditioner does not heat due to the lack of fluoride, the pressure gauge in the air conditioner is to judge whether there is a leak in the air conditioning pipeline by testing the pressure of the air conditioning heating system, if the pressure is lower than the normal value, it means that the freon leakage causes the air conditioner not to heat, it is recommended to ask the maintenance personnel to add fluoride. 3. The power of the air conditioner is not large enough, resulting in the air conditioning not heating, for the space with a relatively large room area and a high ceiling, the power requirements for the air conditioner will be relatively high, and the low power will affect the heating effect, and the high-power air conditioner can be replaced. 4. Filter dust will block air circulation, if you do not clean the filter in time, the dust will block the air outlet and reduce the air outlet, the hot air can not come out, and the heating effect will become worse.
