Symptoms of air defective conditioning +47 causes + solutions

1. Possible causes of air conditioning failure

The air conditioner is a climatic system, which cools the air in a car. This is due to the refrigerant, which circulates in a closed system. Regardless of the vehicle brand and its cost, the design of the air conditioner is the same, the difference constituted only in its structural elements, the operational principle is similar.

The possible causes of failure of air conditioners on vehicles, depending on the external symptoms are:

2.

The CA pressure sensor is designed to protect the system from damage caused by overpressure. When this sensor is defective, the error P0533 appears.

The main causes that lead to the pressure of the pressure sensor are:

• Too much or too little refrigerant
• Improper operation
• Cooling fan defect
• The sensor is losing
• Damage to threads and contacts
• High humidity in the cooling system

3. Simptome includes the AC defect

The compressor is the main component of an air conditioner. He compresses the Freon and circulates it through the pipes of the evaporator.

The symptoms of an air air conditioning compressor for defective cars are:

• Foreign noise – More commonly, the noise in the form of a cycline occurs when the light pad is defective. It is a serious malfunction, which can lead to the breaking of the electromagnetic clutch, the deterioration of the compressive front lid, the cracking of the gasket and the loss of the refrigerant.
• The electromagnetic clutch does not work properly when applying the voltage correctly. The clutch block leads to the interruption of the operation of the air conditioning compressor.
• Lack of tension. – defect that can be easily resolved
• Hot air instead of cold, even if the device has been set to a small temperature: electrical touch blocked.
• Liquid losses-if the compressor bearings have been used, they can no longer keep the liquid when the cooling agent are pressing.
• Freon’s volume in the system does not correspond to the norm, being too or insufficient.
• The radiator is very dirty or the cooling fan is defective. Therefore wear is accelerated.
• Blocked thermal expansion valve
• Deformation of conductive pipes

4. Symptoms are lacking in Freon air conditioning

Any car that has a system of air conditioning or air conditioning, sooner or later, will have to face the recharge of Freon’s installation. Freon is a mix of gas with the property to be vaporized at very low temperatures, even very low compared to the rooms to cool.

The symptoms that indicate Freon’s lack of installation are:

• The cooling of the air is not correct
• The internal and/or external unit of the device does not work properly
• Cracking Cracks Crunching can lead to a rapid loss of Freon
• The compressor clutch does not mate
• Ice on the compressor

5. Symptoms lack of oil compressor

Many people forget a very important thing, that the oil used in the air conditioning system is mainly intended to lubricate the moving components, namely the compressor and the needle of the expansion valve. In addition, the oil guarantees the cooling of the compressor. As for the Freon, the oil in the air conditioning system must be resistant to chemical, which is why its quality and chemical properties must not be neglected. An inappropriate lubrication induced by the use of a lower oil, is the second most common cause of damage to the air conditioning compressor. Professionals of the repairs of air conditioners for vehicles use the term «black death». This appears due to the lack of lubrication of the air conditioning system. Usually when the oil is missing, the metal particles appear that spread throughout the system, clogging other components of the system, which subsequently require a complete washing and replacement of the components. For example: compressors in the air conditioning system in Ford vehicles are the most sensitive to the lack of lubrication. Similar problems also occur in the compressors found in the GM and Chrysler vehicles.

The symptoms of the lack of oil in the compressor of the Balm for Car are:

• The compressor works correctly, but sometimes it starts making noise during operation
• If the compressor pressure plate is rotated manually, it opposes a certain resistance
• When the system is partially disassembled, the traces of metal chips are visible on the expansion pipes and components of the compressor.

6. Causes of the defective AC clutch compressor

To understand why the clutch of the CA compressor is defective, you must first know that it is composed of:

• Electromagnet
• Bearing
• Pressure disk

The causes that lead to the defect of the clutch of the air conditioning compressor are:

• The defective operation of the bearing, which caused the mating overheating
• The block of the compressor, after which the press stopped and the light continued to rotate, until the electromagnet was burning due to the heating and opened the circuit.
• The increase in pressure in the system subjected the clutch to the maximum loads.

7. Why isn’t the couple of air conditioning compressor?

Often, the compressor of the car air conditioner does not mate, because the Freon is drained. The reasons for these losses are:

• Mechanical deterioration
• Defective operation of the bearing and patch
• Defective operation of the electromagnetic clutch
• Defect in the piston group
• Cracks in the compressor body
• Wear of rubber gaskets
• A weak voltage belt
• Break the fuses
• Interruption of the electrical circuit
• Accumulation of usury products and other contaminants

8. Air conditioning smell – Here’s what to do!

It is a paradox, but the responsible system of the comfortable climate in the car can become a source of discomfort. The smell inside the car is the «merit» of the air conditioner. There are several treatments for the vaporizer, such as: aerosol in boxes, foam, smoke bomb, etc. It is better to face a Service carWhich will remove the vaporizer outside, clean it and cosmetize correctly, removing all the misery and accumulated bacteria. This operation is recommended, because bad smell is actually a dusty air and bacteria, which can affect the health of people’s lungs in the machine.

9. Solutions for the most common symptoms of a defective car conditioning!

After carrying out any repair work relating to the restoration of the air conditioning system, experts recommend carrying out a preventive washing of both circuits before refueling with Freon. This solution will eliminate all types of contamination with fats and/or liquids that interfere with the efficient operation of the car conditioned in the car.

The air conditioning is rather expensive and the inability of the car appliances involves serious costs. To avoid these defects, the most useful solution is prevention, following the advice below:

• From the little time for the periodic maintenance of the air conditioner of your car. As a rule, the range of services is one year and it is better to perform these works in the spring, with the start of the active operational season of the air conditioner.
• It is recommended to periodically start the air conditioner, regardless of time or the season; It should be started for 10-15 minutes, at least once a month, so you will ensure constant circulation of oil in the system, reducing the probability of corrosion and clogging due to stagnation on installation. In this apparently trivial way, you will ensure the maintenance of seeds, reducing the risk of refrigerant losses.
• Wash and clean the accumulated dirty capacitor regularly, inspect the components of the air conditioner.

The correct care of the air conditioner on your car will guarantee its long and reliable operation.
