What s the deal with the constant sizzling of the air conditioner when it heats up?

The sound emitted by the heating unit of the air conditioner may also be caused by the unconstant organization of the air flow. For example, the filter is very dirty, which causes the air intake of the air conditioner to be blocked, which will make the internal unit noisy. It is enough to clean the air conditioner, and it is best to clean the filter once every half a month.

The sound emitted by the heating unit of the air conditioner may also be caused by the air conditioning parts not being installed properly and hitting each other. We can check whether the air conditioner cover is tightly covered, whether the fixed wall of the internal and external units, the indoor extension motor, the connecting pipe of the internal and external units are firmly installed, whether the air conditioning fan is stuck, whether it needs to be lubricated, etc.

1. The wall is not firm or the installation position is on the top, causing the wall resonance, the outdoor unit should be installed on the outer wall from the concrete beam of the floor as far as possible, so that the installation is the most firm, the noise is the smallest, and it will not cause the wall resonance.

2. The screws fixed by the bracket are loose or the outdoor unit is not firmly installed.

3. If the compressor base is not fixed firmly or the pipelines in the machine collide with each other, if the distance between the pipelines is too close, it is recommended to separate.

4. The fan blades of the outdoor unit are deformed or broken, the fan bracket is loose or the fan motor bearing is seriously worn and the lubrication is poor, etc., which should be checked and eliminated one by one.

If it keeps ringing, it may be the sound of air flow, and the heating is that the gas is directly from the compressor to the indoor unit, and the high-pressure gas flows in the pipeline, and there may be noise.

If it's intermittent, it may be that the air conditioner has gone into defrosting. There is also noise from the change of air path. If you want to solve it, you should find after-sales service.

This is the sound of refrigerant flowing! If it does not affect the use! Just use some! If it doesn't work out! That's a serious interception! It's troublesome to fix the advantages.

Poor contact ignition has to see a doctor.

The sizzling sound of the air conditioner leaking and sizzling can be caused by the following reasons:

1.Condenser plugging: When the water in the condenser flows through, it will make a sizzling sound. If it is not cleaned for a long time or if the filter is dusty and dirty, it will cause the condenser to clog.

2.Insufficient refrigerant or compressor failure: If the refrigerant inside the air conditioner is insufficient or the compressor is faulty, it will cause abnormal noises in the entire air conditioning system, including the noise of searching and dismantling.

3.Loose or deformed pipes: Poor connection between pipes and pipe joints or deformation and damage of the pipes themselves can also cause sizzling sounds in the air conditioner.

4.Aging of air conditioning motor: The air conditioner has been used for a long time, and the motor is easy to make sizzling sound after aging.

The sizzling sound from the air conditioner can be caused by:

Clogged condensate pipes: Air conditioners will produce a large amount of condensate when they are cooling, and if the condensate pipes are blocked, they will crack and produce sizzling sounds.

Evaporator frosting: When the air conditioner is running for too long or the temperature is too low, the evaporator may frost, and this is when there will be a sizzling sound.

Fan failure: The fan inside the air conditioner may malfunction, resulting in poor air flow and sizzling sounds.

Compressor problem: The compressor of the air conditioner is the core component of the refrigeration, and if it fails, it will also cause a sizzling sound.

Other Causes: There are some other reasons that can also cause the air conditioner to make a sizzling sound, such as faulty circuits, loose pipes, etc.

In the summer, many people will use the air conditioner to cool down, but when using the air conditioner, sometimes they will find that the air is making a sizzling sound, what is the reason for this? Let's take a look. 1. The filter screen is dirty and blocked

If we hear a sizzling sound when using the air conditioner, it may be due to a blockage in the filter, which causes the air to circulate poorly, resulting in this sound. At this time, we need to clean the filter, generally only need to clean the dust on the filter, and then put it in the sun to dry. 2. Blocked air outlet:

If we find that the air outlet is in this situation, then it may be because our air outlet is blocked by foreign objects, causing the air to circulate normally, resulting in a sizzling noise. At this time, we can turn on the external unit, gently pat it with our hands to make the foreign matter inside fall off, and then clean it up. 3. There is abnormal sound in the indoor unit

If you hear the sound of the indoor unit in the process of use, it is likely to be caused by the low temperature of the indoor front scale, at this time we can adjust the temperature a little higher. In addition, when installing, be careful not to let the cold air pour directly into the pipe, otherwise this sound will also appear. 4. Compressor failure:

If you hear the sound of the compressor during use, it is likely that there is a problem with the refrigeration system, which causes the compressor to run abnormally, resulting in such a sound. If so, we need to contact the after-sales personnel and let them come to the door to repair and deal with it. 5. The fan motor of the outdoor unit is faulty

If you hear the squeak of the fan motor of the outdoor unit during use, it is likely that this part has been damaged, resulting in abnormal operation of the machine. In such a situation, we should replace the fan of the outdoor unit in time, or let the after-sales personnel repair it. 6. The connecting pipe of the internal machine is loose

If it is found that the connecting pipe is loose in the process of use, this phenomenon will also occur. At this time, we can re-tighten it or replace it with a new one, so that this problem can be solved. The above are the reasons for the sizzling sound of the ** air conditioner, and you can judge it according to the actual situation of your home.

There could be a variety of reasons why an air conditioner is making a sizzling sound.

For example: Air flow: When the air conditioner blows out cold air, it will form the sound and vibration of air movement. This is a normal phenomenon, as long as it does not affect the use and other abnormal noises and can cool down normally, there is no need to worry about picking up stupid birds.

Pipeline pressure: When the refrigerant flows in the pipeline, the expansion and deformation of the pipeline due to pressure imbalance or heat transfer may occur, and the deformation process is accompanied by friction, vibration, etc., and some sounds may also be generated.

Blocked air inlet: If the air filter entering the air conditioner is blocked or damaged, it will cause the air to enter the system smoothly and produce a sound similar to "swishing spring".

There are several reasons why the air conditioner is making a sizzling sound:

1.There are debris on the air inlet, outlet or filter screen of the indoor unit of the air conditioner or the outdoor unit of the excavation: the air conditioner absorbs the air during the working process, filters it through the filter and then sends it out.

If there is debris on the filter or the air inlet or outlet, it will cause resistance when the air flows, causing a sizzling sound. The filter, air inlet, and outlet can be cleaned, or a professional can do so.

2.Fluorine leakage in the pipeline or unnoticed refrigerant sleepiness: When the air conditioning pipe leaks fluoride or the refrigerant is insufficient, the refrigerant pressure decreases, which will cause the refrigerant to make a sizzling sound when it flows in the pipe. If you need to find a fluorine leak or replenish the refrigerant, it is recommended to ask a professional to deal with it.

3.Damage to the internal parts of the indoor or outdoor unit of the air conditioner: such as fans, motors, compressors, etc., if they are damaged or do not work properly, they will emit a sizzling sound. If the damaged parts need to be replaced or repaired in time, it is recommended to consult a professional to deal with them.

4.Insecure or improperly positioned air conditioner: If the air conditioner is not installed securely or in the wrong position, it will cause vibrations and resonances, which in turn will make a sizzling sound. The air conditioner needs to be adjusted and the installation reinforced.

It should be noted that the above are some common reasons, and if you are unable to identify or solve the problem, it is recommended to have a professional overhaul and repair.

Water accumulation inside the air conditioner: If water accumulates inside the air conditioner, it will cause the air conditioner to make a sizzling sound. You can check whether the water tank and water pipes of the air conditioner are blocked or leaking, and the water tank and water pipes need to be cleaned or replaced.

Dirty air conditioner filter: If the air conditioner filter is dirty, it will cause the air conditioner to make a sizzling sound. You can check whether the filter of the air conditioner needs to be cleaned or replaced, and the filter needs to be cleaned or replaced according to the instructions.

Frost inside the air conditioner: If there is frost inside the air conditioner, it will cause the air conditioner to make a sizzling sound. You can check whether the condenser pipe of the air conditioner is blocked or leaking fluorine, and the condenser pipe needs to be cleaned or replaced.

If the air-conditioning compressor fails, it will cause the air conditioner to make a sizzling sound. You can check whether the compressor of the air conditioner has abnormal noise or heating, and you need to contact professional maintenance personnel for inspection and maintenance.

If the above methods cannot solve the problem, it is recommended to contact a professional maintenance personnel for inspection and repair. At the same time, in order to avoid sizzling sound from the air conditioner, it is recommended to clean the air conditioner and replace the filter regularly.

The sizzling sound from the air conditioner can be caused by:

1.The sound produced when the compressor of the air conditioner is working. The air conditioning compressor is the core component of the air conditioner, and it will produce a certain amount of noise when it is working, which is a normal phenomenon. However, if the noise is too loud or the interruption lasts for a long time, it may be that the compressor itself is faulty.

2.The inside of the air conditioner is icing. Sometimes the inside of the air conditioner freezes, causing the air to circulate properly, resulting in sizzling sounds. At this time, you can set the air conditioner as a heating mode to increase the indoor temperature, or shut down to solve the problem of icing.

3.The fan or air duct is loose. If the fan or air duct inside the air conditioner is loose, it will produce noise. At this time, you can check whether the fan and air duct are installed securely, or contact a professional for repair.

Analysis of the reasons for the large heating sound of air conditioning:

1. It may be that some pipelines are deformed due to thermal expansion and contraction and then stick to the compressor or metal shell, which will cause resonance, resulting in noise.

2. Check whether the internal and external units are fixed and strong on the wall, if the fixing screws are loose, it will also cause the air conditioner to vibrate and make loud noises when working.

3. Check whether the connecting pipes between the indoor and outdoor air-conditioning are fixed, and whether they have collided with the indoor and outdoor units or other objects.

4. It is also possible that the refrigerant in the air conditioner makes a louder sound before reaching the equilibrium, and the air conditioner cannot reach the balance when the air conditioner is turned on and stopped.

Air Conditioning Maintenance and Repair:

1. Frequently clean the dust on the air conditioner panel and casing.

Generally, wipe with a dry cloth. Wipe first, then wipe off the detergent with a damp cloth of water. Do not wipe the air conditioner panel and casing with hot water, gasoline, volatile oils and corrosive solvents above 40 degrees Celsius.

Do not use a stiff brush to brush the air conditioner, so as not to damage the shell, causing paint stripping, fading, etc.

2. Clean the condenser and evaporator coil of the air conditioner regularly.

Dust can be cleaned from the coil using a brush and vacuum cleaner. Note that the brush and vacuum cleaner should be cleaned in the vertical direction of the coil, not in the horizontal direction, so as not to damage the ribs of the coil.

What is the abnormal sound of the air conditioner heating: The abnormal sound of the air conditioner may be caused by the unconstant airflow organization, which is caused by hitting each other, or because of the loose screws that fix the gland of the motor. Workaround:

1. Clean the filter screen regularly (should be cleaned once every half a month), if the filter screen is too dirty, the air inlet is blocked, which will not only make the internal machine noisy, vibrate, low wind sound, and the wind speed can not be raised, but also when the outdoor ambient temperature is not too low, it will make the indoor unit evaporator overheating protection and frequent standby, generally about 10 minutes. 2. Check whether the inner cover is tightly covered, sometimes the inner cover is not tightly covered after cleaning the filter screen or after cleaning, resulting in the vibration sound of the air conditioner when working. This answer is applicable to Gree GMV-H180WL C1 and Midea KYR-35 N1Y-PD2 brand air conditioner models.

The situation where the air conditioner makes a sizzling sound is as follows:

First, the sound of the compressor belt may be caused by the damage of the compressor belt tensioner, or it may be the sound of the compressor malfunctioning. This is easy to identify. Second, the sound of the blower, this is not only the sound of the air conditioner, but also the sound when the external circulation is opened, which is generally the loosening of the parts of the air conditioner.

The third is that the cold and warm switches in the panel or the fault caused by the failure of the internal and external circulation motors, the sound is generally the sound made by the sound in the central control panel.

Air conditioning maintenance

When the air conditioner is not used for a long time, in order to fully dry the inside of the air conditioner, it should first run in the air supply mode for 4 hours, add some lubricating oil to the fan motor part, then cut off the power supply, and then cover the air conditioner with an envelope, and cover the outdoor body with a protective cover to avoid sun and rain. At the same time, wipe the remote with a clean, soft, dry cloth and remove the battery. When reusing the air conditioner, it is necessary to do a basic cleaning and do an operation test.

Professional and technical personnel are requested to carry out comprehensive and thorough cleaning and maintenance of the core components of the air conditioner from the inside to the outside, so as to find the hidden problems of the air conditioner in time, effectively extend its service life, and be healthier and more energy-saving. The in-depth maintenance of the air conditioner is generally sufficient once every 2-3 years.

Tightly closed doors and windows should not rely on air conditioning to raise and lower the temperature for a long time, and windows should be disconnected for ventilation to maintain indoor air circulation and avoid lack of fresh air. The installation of an air conditioner and a ventilator can deliver a large amount of filtered fresh air to the air-conditioned room.
