As temperatures rise, role of car air conditioners becomes more important. However, when many people use car air conditioner, they find that air conditioner does not cool from time to time. Some people will panic, not know what to do or even how to deal with it, and worry that they will be deceived when they go for maintenance. Today, I will briefly talk about how to deal with this and put a four-step self-test method to easily find problem and fix it.
If air conditioner is not cooling, check air conditioner filter first
The cabin filter is an important part that ensures smooth operation of air conditioner. If filter is clogged or dirty, it will affect airflow and reduce cooling effect. Car owners can check for themselves whether filter is dirty or clogged, and if it needs to be replaced, they can go to a car repair shop or a 4S store to buy an air conditioning filter suitable for their model for replacement.
Check A/C compressor
The air conditioning compressor is main component of cooling system. If compressor fails, cooling effect will inevitably suffer. The car owner can try turning on car's A/C switch while engine is running and A/C is off, and listen for sound of compressor running. If there is no running sound, compressor may be defective. At this time, car owner needs to go to the car repair shop for inspection and maintenance.
Check capacitor
A condenser is an important cooling component of an air conditioner that dissipates heat. If surface of condenser is dirty or heat dissipation is poor, cooling effect will be affected. The owner can check if surface of condenser is dirty or clogged, and if so, use a professional condenser cleaner to clean it. In addition, car owners can also check if condenser cooling fins are intact, if there is deformation or blockage, you should contact car repair shop for repair.
Check for leaks in air conditioning piping
For this method, you first need to know where air conditioning pipe is located. It's usually easier to find. There are relatively small aluminum tubes in engine compartment of a car. There are H and L standards on inner interface cover. Spray water on pipe to see if there are bubbles and like, can of course be checked with special tools, but this requires understanding principles of air conditioner, and you can go to repair shop , to solve this problem. .
The above self-test method consists of four steps. You can check for problems with air conditioner yourself according to method described above. If above methods cannot solve problem, it is recommended that you go to an auto repair shop in time for inspection and repair. At same time, in daily use, it is also necessary to pay attention to maintenance of air conditioner, clean air conditioner filter and condenser regularly, keep air conditioner clean and extend life of air conditioner.
