As soon as the car turns on the heater, it smells of burning rubber

The car has a burnt smell when the heater is opened, why?

There are many reasons for the smell of turning on the heater when driving, such as not using it for a long time, or the air filter is dirty, in this case, if the odor is not always a problem, it is not big, but it is still necessary to judge the odor according to the actual situation**!

If you turn on the heater, the external circulation mode used, there is a smell from the engine compartment, and there are a lot of plastic and rubber parts in the engine compartment, the temperature becomes higher after the engine works normally, some plastic and rubber parts may emit a mushy smell, especially for new cars, but this smell will disappear soon, if the smell is obvious, and there is a long-lasting odor, it is recommended to test the engine compartment, either there is oil leakage or leakage!

If the use of internal circulation, generally will not have a burnt smell, after the smell of burning, or should be ruled out of other situations, if only the heater has a burnt smell, then this is a normal situation, because there is electric auxiliary heating, is the smell of electrical components when working, warm air through hard plastic pipes, plastic heating, and some car air outlet material is also related, this situation is basically just beginning to have hot air.

So don't worry!

Three countermeasures for the smell of burnt smell in cars.

1.If you smell a non-metallic material with a burnt smell, it is usually the clutch.

The friction plate is burned out or too hot. This burnt smell is usually mixed with a burnt smell, as the clutch plate material is also due to rubber and asbestos.

Waiting for some materials to be compounded, that time also needs to be dealt with by the repair shop!

2.Long downhill times or handbrake.

Forget to put down that brake pad when you put it down.

It is easy to heat up too high, resulting in a mushy smell on the tires, so it is best to pull over immediately if you smell the bad smell.

Wait for the brake pad temperature to slowly decrease before driving. In addition, perhaps due to the engine belt.

If there is a failure, then it is also necessary to check whether the belts in the engine compartment are loose and slippery!

3.If you smell plastic paste, it is mostly caused by the heat of the electrical wiring. Burned wires often have localized heat.

As long as you carefully detect the smoke, it will not be difficult to find the cause of the accident, and then you can determine where the car is malfunctioning!

Hello, the current number of people consulted may not reply in a timely manner, if it is a vehicle failure problem, it is recommended to use the computer to detect the specific cause of the failure, search for "car master" can consult car problems at any time, 24 hours ** answer.

All car owners will turn on the heater air conditioner in the car in winter to make the car a little warmer, but there are also car owners who report that the heater has a smell of burning rubber, and want to know what the situation will be The reason why the car has a burnt rubber smell when the heater is turned on, you can learn about some of the reasons why the heater has a burnt rubber smell:

1. The owner can check whether the air conditioning line has been aged, or the heating wire is abnormal, resulting in the heating wire temperature being too high, which makes the car have a burning smell.

2. This situation is more likely to occur for new cars, because there are a lot of plastic and rubber parts in the engine compartment, and when the engine temperature rises, it is possible to make these plastic parts heat up and emit a burnt smell.

3. The owner can also check whether the air volume of the air conditioning outlet is large. If not, it may be that the air outlet is blocked, preventing hot air from entering the car, causing the plastic in the air conditioner to heat up and burn and emit odors.

If not, you can go to a 4S shop or repair shop to find a professional maintenance personnel to open the air conditioner to see which parts are damaged and the heater will emit a burning rubber smell, and replace the faulty components for maintenance.

In addition, it may also be that this is not a good point if it is opened into an internal loop. The second is to check the cabin filter. You can clean the air duct of the air conditioner.

Changing the filter element and cleaning the air duct are generally less than 15. It is advisable to check the exhaust pipe on the engine for blockage. Check the engine for oil leaks.

The warm air in the car has a choking smell and is caused by bacteria in the channels of the air conditioning system. If the occupants of the car have the habit of smoking or often do not use the air conditioner, and do not continue to turn on the blower for a period of time, it will be shut down immediately, and it is easy to make the condenser moldy. When the air conditioner is turned on for heating, the smell is stronger.

It is recommended to clean the car air conditioner once a year, and if conditions permit, the air conditioner can be sterilized once every season.

There are generally two methods of air conditioning disinfection, using ozone disinfection and dismantling parts for cleaning and disinfection, the owner can buy an ozone machine to plug in the car, close the doors and windows, and then open the air conditioning cycle, the temperature is the highest, the air volume is the largest, and it can be disinfected in about 20 minutes.

Because the temperature of the fan inside the heater is too high, the temperature of the plastic inside the air outlet will be very high. The materials used in the interior walls of the car are not environmentally friendly, and when the temperature rises when the heater is turned on, the unpleasant smell of the inner wall will waft out. The car is not purified and the air is not circulated, so it is easy to smell of burnt skin.

There is a failure in the system, the wind is turned on too much, the heat is too high, the air conditioner is used for too long, and the material of the heater is not good, because of these reasons, the car will be turned on the heater, and there will be a burning smell.

It may be because the car's heater is faulty, or the car's oil is not changed in time, or there is a problem with the car's coolant, or there may be some problems with the car, or it may be that the car is not driving in the right way.

The car is not maintained, the car wiring is aging, the heating wire is abnormal, the heating wire temperature is particularly high, the air volume of the air outlet of the air conditioner is not very large, and so on.

The smell of gasoline when the car heater is turned on may be an external engine leak, an air conditioner filter, and a mold in the air conditioning duct, which are described as follows

If there is an exhaust gas leak from the external engine and a foreign object at the air intake, it will be obvious to see that it enters the air inlet of the air conditioner from the air conditioner.

Precautions: 1. The fuel supply system of the car is a closed system, and there is generally no gasoline vapor escape. But there is a part of the area from which gasoline vapor escapes if it malfunctions or we use it improperly, causing the smell of gasoline in the engine compartment.

2. If the gasoline is overfilled, the snorkel is also filled with liquid gasoline, and even the carbon canister is also filled with gasoline, in this case, the carbon canister will not work properly, and the gasoline will escape into the engine compartment.

In the northern winter, the drivers will turn on the heating as soon as they get in the car, and it can be said that the heating is given in winter. However, some car owners find that the wind that will blow out after their car turns on the heater will have a strong smell of engine oil, so why does the car turn on the heater with organic oil smell? How do we solve this?

In some models, the air conditioning damper is installed in the engine compartment, which means that some of the air comes from the engine compartment, and when the engine leaks or leaks, there will be a phenomenon of organic oil smell in the warm air. Secondly, if you turn on the external circulation while driving, the smell of oil in the engine compartment will enter the cabin along the external circulation pipe. Finally, if the air conditioner filter we replace is stained with some oil, the warm air blowing will also smell of organic oil.

Warm air organic oil odor treatment method.

When there is a smell of organic oil in the warm air, we can try to adjust the air conditioner to the internal circulation, which is just to continuously circulate the air in the cab so that there will be no organic oil smell. Secondly, we should check whether there is oil leakage in the engine, generally open the engine to see if there is oil stains or sludge near the cylinder head, if there is, it should be repaired as soon as possible, and the oil smell will disappear after repair. Finally, we should check whether the canister can work properly, if the canister does not work properly, the fuel vapor in the fuel tank will go to the atmosphere and then be sucked into the cab by the fan, and we need to replace it in time when the canister fails.

Why does it smell of gasoline after getting into the car?

Filling up too much, aging rubber lines of the canister, poor or not properly sealed fuel tank caps, leaking gasoline pipes, and cracked gasoline pumps can all be the causes of gasoline smell in the car that are not easy to inspect or easy to ignore. If the refueling is too full, the gasoline will overflow, and enter the carbon tank along the pipeline, the role of the carbon tank is to collect gasoline vapor, when the gasoline flows to the carbon canister, the carbon canister will release excess gasoline vapor from the vent, and if the air conditioner external circulation is turned on, the gasoline smell can enter the car.

Well, this heater is basically the smell of machine heat dissipation, if there is a smell of burning oil, it means that your engine, I don't know where it is overheating, resulting in the smell of burning oil, you can check it, this is not normal, it should not be asked.

If the car heater has the smell of burning oil, it should be checked carefully where there is oil leakage in the engine of your car.

It may be that when doing maintenance, the oil drain plug of the oil pan is not tightened, and the oil seeps to the bottom plate or guard plate, and there will be organic oil smell as soon as the car is hot, or the exhaust pipe is broken and leaked!

This is the pipe of the heater or some places, so it will smell of organic oil. You can find a repair shop and ask the master to check the reason for you.

If you open the external circulation, the smell in the engine compartment will enter the cab along the external circulation pipe, so you will smell the smell of engine oil I hope it will help you, hope!

The car heater has a kiss on it, it may be uh the temperature of the car is too high. The smell of the chicken used came down the way, so it was necessary to wipe down the text of the vehicle or the muscles on the car.

Oil is very important for the engine of a car, the oil is called the blood of the engine, if there is no oil in the engine, the engine will not function properly.

That's because there is dust on the electric auxiliary heater, and there is also the dust and bacteria in the environment attached to the filter screen and the evaporator of the indoor unit.

There are two main situations in which the air conditioner has a burning smell:

1. Caused by electrically assisted heating. If your air conditioner is electric-assisted, it is because the electrically assisted heater has dust on it, and the dust and bacteria attach to the filter and the evaporator of the indoor unit, and after heating, it bakes at a high temperature, and it has a burning smell. If it is the first time to heat, then this situation is normal.

Second, the electrical wiring problem. If your air conditioner is not an electric-assisted type, it is reasonable to say that it will not smell, then the burning smell is likely to be caused by a problem with the wiring of the electrical appliance.

1.Ventilation is strengthened.

It is common to have odors when using the warm air of a car air conditioner in winter. After using rain and cold air in summer and autumn, the air conditioning system on the car is humid and easy to breed bacteria, and the doors and windows are closed when the heater is turned on, and the car is prone to odors. For the unserious air conditioning odor, the owner can find a sunny day to drive in the sun, put the air conditioning system in the warm air block, and then adjust the air volume to the maximum, and open the doors and windows for ventilation for more than 10 minutes.

2.Replace the cabin air filter.

Regarding the maintenance of the air conditioning filter, the air conditioning filter is the filter element imported from the air conditioner in the car. If it is not replaced for a long time, the dust attached to it will blow into the car with the air conditioner turned on, causing respiratory tract, allergies, vomiting and other diseases. In general, the air conditioner filter should be replaced every 20,000 km or 12 months.

3.Caused by mold inside the evaporator and air conditioning lines.

If it is caused by mold inside the evaporator and air conditioning pipeline, we can make some improvements through the non-disassembly cleaning of the air conditioning evaporator and pipeline, that is, adding the foam cleaning agent of the air conditioning system to the air conditioning pipe and evaporator to complete the cleaning, because there is no direct contact treatment, it is difficult to completely solve the problem, generally washing in the outside auto repair shop is about 200 yuan, if the situation is serious, it is best to wash it several times in a short time, if it really doesn't work, you can only disassemble the evaporator to wash, the cost will be very high.

This may be due to some overheating of the heater, or it may be due to uneven heat dissipation. You can put some aromatherapy in the car, you can also put some essential oils, or you can put some wormwood or activated charcoal on the heater.

You can open the window for ventilation, sometimes it is some plastic pieces, some smells occur, and there is no longer it after a long time, if it is more serious, you should find after-sales, it is likely that there are some problems inside the vehicle.

You can put some adsorption carbon packets in the car to let these smells out, or you can open all the windows of the car when driving to let the smell disperse quickly.

We can choose to remove the heater from the car and wash it and then turn it back on, which can reduce the smell of burnt plastic.
