What is the reason for the burning smell of the air conditioner?

If the outside unit of the air conditioner has a burning smell, it may be one of the following reasons:

Wire short-circuited orFaulty circuits: When there is a short circuit or circuit failure in the wires of the air conditioner, the current may be too large, causing the wires and electrical components to overheat or even burn, resulting in a burning smell.

CompressorsProblem: The compressor of the air conditioner is one of the core components of the air conditioner, if the internal parts of the compressor are damaged or the lubricating oil is insufficient, it may cause the compressor to overheat or even burn, resulting in a burning smell.

FanProblem: The fan of the air conditioner may also malfunction, such as motor damage or deformation of fan blades, which may cause the unit to overheat and produce a burnt smell.

ExternalEnvironmental issuesIf the air conditioner is placed in a humid or poorly ventilated environment, it may cause the electrical components to become damp or overheated, resulting in a burning smell.

If you find that the air conditioner has a burning smell, you should stop using it immediately and contact professional maintenance personnel for overhaul and maintenance. At the same time, in order to avoid the recurrence of similar problems, it is recommended to regularly clean and maintain the outdoor unit of the air conditioner to ensure its normal operation.

The smell of burnt air conditioning.

1. There may be a "peculiar smell" caused by the deposition of mold or foreign matter inside the air-conditioning pipeline. Second, it may be due to the "peculiar smell" of the plastic parts of the air conditioning system itself, and the plastic also "heats up" when the air conditioner is hot, especially some parts with bad materials. 3. It may be that the line is heated or affected by the temperature increase after aging, and the insulation is heated and volatilized or even melted, and the "peculiar smell" may be emitted.

Fourth, the air conditioner filter has the possibility of foreign matter adhesion or poor ventilation causing "peculiar smell". 5. Other parts are brought into the air-conditioning system due to the "peculiar smell" emitted by short circuit of the line and the burning of electrical equipment. Sixth, the reason of the external environment, through the air conditioning system "inhale" the possibility of bringing into the interior.

6. The possibility of "peculiar smell" caused by other parts or causes is not ruled out. The reasons for the burnt smell in the heating of the air conditioner include: 1. The air conditioner will accumulate dust on the filter screen and the copper sheet inside the air conditioner after a long time of operation.

Dust can also accumulate between the fins of the heat exchanger, which will cause clogging after accumulating to a certain amount; A certain odor is generated, and as the air conditioner is turned on, the odor from the air conditioner will drift into the air. 2. After the air conditioner is heated, there will be moisture inside the indoor unit, so when the air conditioner is turned off, the air conditioner without dry and mildew prevention function will be shut down immediately, so that the internal moisture has always existed, and mold will be produced in the long run. 3. The air conditioner has not been enabled for a long time

Because the condensate trapped on the heat exchange coils, fins and their peripheral parts slowly evaporates, creating high temperature conditions around the coil that are suitable for microbial reproduction, a large amount of gas produced by microbial reproduction will be released under the drive of the air conditioning system, resulting in a burnt smell. Due to the many reasons for the burnt smell of the air conditioner, users should immediately stop the air conditioner and cut off the power supply when they find this phenomenon, and contact professional maintenance personnel for on-site maintenance and cleaning.

What happens when the air conditioner has a burning smell: 1. If the air outlet is in good condition, and the burnt smell does not belong to the smell of plastic and rubber, it usually does not matter, it may be that when using electric auxiliary heating, the dust on the heating tube is baked, and the smell will slowly disappear after several uses.

2. If you smell plastic, it may be that the air outlet of the air conditioner is blocked, resulting in the hot air in the air conditioner not coming out. If the heat cannot be dissipated, it will cause the plastic cup inside the air conditioner to burn, first check whether the air conditioner outlet is blocked, test whether the wind at the air outlet is very strong with your hands, if it is very small, it is recommended to open the air conditioner for inspection, and clean up the foreign objects that fall out of the air outlet.

3. It may also be that the circuit of the air conditioner is aging or the heating wire is abnormal, resulting in the temperature generated by the heating wire being too high, and the machine needs to be disassembled for inspection.

This answer is applicable to Gree GMV-H180WL C1 and Midea KY-15 N7Y-PHA brand air conditioner models.

Summary. Hello 1, if you smell the smell of burnt plastic, it may be that the air outlet of the air conditioner is blocked, resulting in the hot air in the air conditioner cannot come out, and the plastic inside the air conditioner is scorched. Check whether the air conditioner outlet is blocked, test the wind strength of the air outlet with your hands, if it is small, you need to open the air conditioner to check, and clean up the foreign objects that fall out of the air outlet.

2. The circuit of the air conditioner is aging or the heating wire is abnormal, resulting in the temperature generated by the heating wire being too high. This problem requires the machine to be disassembled for inspection.

What's the matter with the smell of burning outside the air conditioner.

The smell of glue in the air conditioner.

Fainting. Refunds.

If you smell the smell of burnt plastic, it may be that the air outlet of the air conditioner is blocked, resulting in the hot air in the air conditioner not coming out, and the plastic inside the air conditioner is scorched. Check whether the air conditioner outlet is blocked, test the wind strength of the air outlet with your hands, if it is small, you need to open the air conditioner to check, and clean up the foreign objects that fall out of the air outlet. 2. The circuit of the air conditioner is aging or the heating wire is abnormal, resulting in the temperature generated by the heating wire being too high.

This problem requires the machine to be disassembled for inspection.

If the air outlet is in good condition, and the burnt smell does not belong to the smell of plastic and rubber, it usually does not matter, and it will be fine after a while; If it is the smell of burnt appliances, you need to open it for inspection.

Air conditioning heating is the use of heat pump principle to move heat energy from the outside to the interior. Some air conditioners will be supplemented with electric heating.

The temperature of the heating devices is relatively high when the air conditioner is heating, and the surface of these heating devices will inevitably be contaminated with dust, lint, and even some small insects and the like, which will produce a burning smell when heated. In particular, air conditioners that have not been used for a long time after being used in the summer have a humid interior during refrigeration, and the dust is easy to form a mud-like form and attach to the parts, and the smell will be relatively large when it is heated for the first time in the year. After a period of time, the volatile substances in it have evaporated and the flavor will not continue to be produced.

If the air conditioner does not ventilate after a few minutes of turning on, or there is a smell of burnt electrical materials, the air conditioner may be faulty and should be repaired by a professional.

It is best to clean the interior of the air conditioner once or twice a year, and it is best to cover the top of the hang-up unit with a cloth or paper if it is not used for a long time to reduce the entry of dust.

If the smell is not the smell of burnt plastic, it may be that the dust on the heating tube is baked when using electric auxiliary heat, and the smell will slowly disappear after a few uses. If the smell is unbearable, it is recommended to turn off the electric auxiliary heat of the air conditioner, or ask the air conditioner maintenance personnel to disassemble the air conditioner to clean the dust on and next to the heating pipe.

After the air conditioner is turned on, the maintenance times during the air conditioner start-up process are determined by many factors such as environmental conditions, climatic conditions, number of hours of start-up, surrounding dust, air cleanliness, and whether the room is clean. The environmental conditions are not good, the weather is hot, the air conditioner is outdated, the air conditioner is turned on for a long time, and the number of maintenance during the air conditioner start-up process increases, usually once every month and a half.

If the environmental conditions are good, the air conditioner is relatively new, there is less dust in the air, the air conditioner is turned on reasonably, and the electric fan is used alternately, the maintenance cycle can be appropriately extended, from the start of the air conditioner to the shutdown of the air conditioner for maintenance 1-2 times. Maintenance should be careful and careful, leaving no dead ends. Comply with the specifications, improve the refrigeration speed and refrigeration effect, and achieve energy saving, freshness and comfort.

After the air conditioner has been used for a long time, after turning on the air conditioner, the air conditioner will emit a peculiar smell, which is very unpleasant, which affects the air at home, in order to improve this phenomenon, I specially found a professional air conditioning maintenance master to check and clean, according to the maintenance master, there are many reasons why the air conditioner has a peculiar smell, they are:

Reason 1: After the air conditioner is used for many years, the indoor filter and copper sheet will squeeze a certain amount of dust, so that after accumulating a certain amount, a certain odor will be generated, and with the air conditioner turned on, the air conditioning outlet odor will drift into the air.

Reason 2, because the air conditioner in the refrigeration heat, in many cases, there will be moisture inside the indoor unit, so when the air conditioner is turned off, the air conditioner without dry and mildew prevention function will be shut down immediately, so that the internal moisture has always existed, and mold will be produced in the long run, and the musty smell will naturally occur.

Reason 3: The system has not been running for a long time, and the heat exchanger ribs are nearly full.

Reason 4: Some non-high-efficiency filter systems at the end of the air supply, such as computer rooms, hotel rooms, etc., although the interior decoration is good, and the fresh air and air conditioning air supply are filtered, dust can still be found near some indoor air supply outlets and on the surface of the window sill, and a layer of dust is also adhered to the surface of the internal parts of the machine.

Reason 5: After the air conditioning system is started, the concentration and odor of indoor bacteria increase, which is due to the slow evaporation of the condensate retained on the heat exchange coil, ribs and their surrounding parts to form a high humidity (and high temperature) condition around the coil, and become an environment suitable for microbial reproduction, and a large amount of gas generated during reproduction is suddenly released due to the system drive, becoming the source of foul odor. It is believed that the large amount of dust brought by the fresh wind and accumulated in these places not only carries microorganisms, but also provides indispensable nutrients for microorganisms to multiply.

After the air conditioner odor is cleaned, the air conditioner is cleaned.

Do 1 more step at a time.

Cleaning the filter is not enough Radiator cleaning and disinfection is the key At present, there are still most households that usually only stay at the filter level for cleaning the air conditioner, in fact, this can not completely remove the pollution caused by the air conditioner. Because the filter only filters a part of the dust, some dust will still accumulate on the heat sink through the filter and accumulate a large number of germs. After understanding the real cause of air conditioning pollution, we can do one more step at a time to clean the air conditioner, clean the filter screen and clean and disinfect the air conditioner radiator, so as to effectively inhibit the bacterial breeding of the radiator and bring pollution to the indoor air.

Disinfect 1 time per month.

Clean and disinfect the air conditioner radiator every month In addition to developing the habit of cleaning and disinfecting the air conditioner in 1 more than 1 step each time, it is also necessary to clean and disinfect the air conditioner radiator regularly. Every year, the air conditioner should be thoroughly cleaned and disinfected before the first turn on during the seasonal season, but in the months when the air conditioner is frequently used, such as summer, because people may stay in the air-conditioned room for a long time, the indoor air quality directly affects our health, so the air conditioner needs to be cleaned regularly. The easy way to do this is to disinfect the air conditioner once a month.

Hello answer, about your question, I learned that 1. There is a lot of dust in the environment where the air conditioner is used, resulting in a large amount of dust covering the heating pipe inside the air conditioner. When the heating is turned on, the dust is heated and produces a burning odor. Workaround:

Remove the cover of the air conditioner's internal unit and wipe off the dust from the internal heating pipe with a dry towel. In the process of long-term non-use, cover the inner unit with a dustproof cloth.

2. The air outlet is blocked, and the hot air is blocked, resulting in all the heating being added to the external plastic of the air outlet, resulting in a burning odor. Solution: Turn on the air conditioner, check the status of the air outlet of the air conditioner, whether it is blocked, and clean it up in time if it is blocked.

3. The heating wire is abnormal. Solution: Go to the after-sales service department of home appliances for disassembly testing and replace the heating wire with a new one.

Question: I use it today, I go out at noon and turn it off, and when I come back at night, I have a burning smell.

Answer: If the air outlet is in good condition, and the burnt smell does not belong to the smell of plastic and rubber, it usually does not matter, and it will be fine after a while; If it's the smell of burnt appliances, the air conditioner is out of order. At this time, the air conditioner should not be used anymore, and professionals should be asked to overhaul it in time.

Question: Did the electrical appliances inside burn out after being turned on to the lowest temperature for a long time?

Probably heating or cooling, normal.

If you continue to use it for a period of time, if the burning smell gradually decreases, it is because the electric heating assist is also put into work when the heating is enabled, and the smell of dirt and dust near the heater is baked, and it is fine;

If the burning smell of long-term heating becomes more and more serious, it means that the electric heating auxiliary circuit is damaged, and it is recommended to ask an expert to disassemble the cover to check and deal with it.

This happened after the maintenance, and later found that some oil was sprinkled near the oil port when the oil was changed, and there was a mushy smell after the engine was hot.

There are generally two reasons for the burnt taste.

1: The air inlet of the air conditioner is blocked, resulting in the hot air inside not being blown out, the heat cannot be dissipated, and the plastic parts are scorched. The elimination method is to check whether the air inlet is unblocked, and then test whether the air outlet is normal with your hands, and listen to whether there is any abnormal sound in the air conditioner.

2: The circuit is aging, the circuit is scorched by heat when the electric heating is electrically heated, or the plastic parts are displaced internally, resulting in heating. If this is the case, it is necessary to disassemble the machine for inspection and repair.

Maybe the plastic woven bag is wrapped around the exhaust pipe under the car, and the exhaust pipe is very hot and melts, but every time the car runs for a long time, there is a mushy smell, and then the plastic residue on the exhaust pipe is hung up. You can go to a car repair shop to see if it is a similar problem.
