24 Volt Air Conditioner Compressor Failure and How to Repair the Compressor?

What is an Air Conditioning Compressor?

An air conditioning compressor is the part that compresses and pressurizes the air conditioning gas. This system takes the movement from the engine with the crank pulley and belt.

How Does an Air Conditioning Compressor Work?

It is used to increase the pressure of the refrigerant in the air conditioning compressor. In this case, the temperature of the coolant also increases. In other words, refrigerant enters and exits the air conditioning compressor, cold air enters and hot air comes out, low pressure enters and exits as high pressure.

Vehicle Air Conditioning Compressor Types

Piston Technology

Spiral Technology

Crawler Technology

Swash Plate Compressor (the latest system)

What are the Air Conditioning Compressor Failure Symptoms?

When the air conditioning in the vehicle is broken, the problem may be caused by the compressor unit or its internal equipment.

Compressors in vehicle air conditioners generally;

compressor pulley

compressor shaft

compressor gas

gas inlet


It consists of valve and valve sockets.

When the air conditioning compressor malfunctions, the vehicle air conditioner usually does not turn on.

Repairers usually solve this problem by replacing the air conditioning compressor. However, it is possible to resolve the fault without replacing the compressor. There are test devices to find out the fault in the air conditioning compressor clearly.

The usage advantages of air conditioning compressor testers are quite high.

Simulation of real operation in a car.

Detection of mechanical (impact, vibration) and visual malfunctions (feeding and suction pressure).

Real-time tracking of test results.

Load control in a tested unit.

Electromagnetic valve control from 0 to 100%.

MS111- AC Air Conditioning Compressor Test Bench

It is much easier to test defective compressors with the Ms111 compressor test bench. The repair made to the compressor can be tested actively as if it were on the vehicle. It is designed to test the wide compressor of vehicles on the R134a refrigerant in the air conditioning system.

With the Ms111 compressor tester, it detects malfunctions of the vehicle air conditioning unit, even if it is a remanufactured, repaired unit or a used unit, including those before it was installed in the vehicle.

Thanks to these test devices, you can operate as if the compressor is on the vehicle. During the test, you can see the values ​​given on the Ms111 bench. It also provides facilities such as saving and printing the given values.
