Causes of car air conditioning failure
The air conditioner in a car in summer means comfort and convenience for the driver. It is used in summertime almost daily, what causes the frequent breakages and the necessity of refueling. The reasons of air conditioner malfunction in the car are known not to each driver, as well as the first signs of forthcoming malfunction. Not every driver knows that they get very good money for faulty cars: https://scrapmycarnear.me.
It is important to know how to avoid air conditioner breakdown in the car, how to fix it in case of damage and what the average prices for air conditioner repair in the car service center offer masters.
Despite the fact that the air conditioner has a fairly simple design, it tends to break down. The main reasons for the malfunction of the air conditioner in the car can include the following:
Contamination or breakage of the condenser;
Failure of the car air conditioner compressor;
Broken pressure sensor;
Damage to the thermostatic expansion valve;
Dirty or broken condenser
The condenser is responsible for cooling the fluid that lowers the temperature of the air supply from the system. In other words, it lowers the temperature of the refrigerant (refrigeration agent), which draws off the heat and releases the cooled air. Refrigerants include liquids that change from liquid to gaseous at temperatures below 0°C.
Contamination of the condenser results in poor performance, which is not enough for cooling. This is why the condenser automatically shuts down.
Malfunction of a car air conditioner compressor
The main cause of malfunction of the air conditioner in the car is related to the breakdown of the compressor. This is evidenced by noises and oil leaks from the auto device. Freon (refrigerant) leakage can cause malfunction. It may occur because of wearing of auto conditioner’s parts, circuit failure, outer damage of details and certainly contamination. The main reason is corrosion. Freon leak occurs exactly because of corrosion, and as a consequence, auto conditioner stops working, having faced with lack of coolant.
It is possible to find the place of a leak with the help of car diagnostics in a car service center.
The pressure sensor is responsible for the pressure in the system. If it changes sharply, the sensor will independently shut down all the equipment. Its operation can be affected by dirt, damage to the electrical circuit and improper external influences.
You can check the operation of the pressure sensor with the help of car diagnostics at the car service center.
Thermostatic expansion valve
The thermostatic expansion valve is responsible for supplying freon to the auto air conditioning system based on the set temperature and pressure.
You can tell if the thermostatic expansion valve is malfunctioning by the operation of the air conditioner in the vehicle. Intermittent shutdowns and delivery of cold air that cannot be adjusted indicate a faulty valve.
Evaporator malfunction can be caused by corrosion, a clogged fluid drain, and mechanical damage sustained in accidents and similar situations.
The main signs of evaporator damage are an unpleasant smell in the cabin, traces of fluid, and deterioration of equipment performance.
The air conditioner, having an uncomplicated system, has a whole system of filters that ensure the flow of cold or warm air. They clean the fluid and remove moisture from the system. It is the clogged filters that can cause the air conditioner in your car to malfunction. Initially, the performance will simply drop and then a complete failure will follow.
Filters require special attention after the air conditioner has been charged.
Once signs of a car air conditioner malfunction are detected, it is important to contact an auto service for diagnosis, refilling, or repair in a timely manner. Timely professional service is the key to success and relative savings. Prices for air conditioner repair at an auto service center depend on the complexity of the work performed.
