Function of Car AC Magnet Clutch and Signs of Its Damage

Car AC basically has a number of components, namely the main components and supporting components. Among the many components in the AC, the AC magnetic clutch is a very important component.

This magnetic clutch can be said to be like a pulley that continuously rotates following the engine. If this component is damaged, the performance of the AC will be greatly affected. So, what are the functions and signs of its damage?

Understanding AC Magnetic Clutch

As part of the AC, the magnetic clutch is a component consisting of a magnetic spool, pulley, and clutch. The pulley part will continuously rotate following the engine's rotation connected from the fan belt. This component is also often referred to as the activator and deactivator of the compressor's operation.

Function of AC Magnetic Clutch

The magnetic clutch functions as a connector between the compressor and the engine's rotation. Not only that, the magnetic clutch also functions to disconnect the compressor from the engine's rotation. The main function of the magnetic clutch is to regulate the operation of the compressor.

This component will later regulate when the right time is for the compressor to keep working even though the pulley is rotating in the engine. When the compressor starts to work, the pressure in the Freon section will increase.

If the pressure becomes higher, the magnetic will stop the Freon pressure. The way the magnetic clutch works is that when the car engine is running, the pulley will rotate following the engine's rotation and generate electric current in the magnetic spool.

This will cause the compressor to rotate and Freon to be channeled to the AC. Meanwhile, when the engine is not running, the pulley will stop working because there is no engine rotation. If there is no electric current in the magnetic spool and the compressor does not work, the function of this component also cannot work normally when a malfunction occurs.

Signs of AC Magnetic Clutch Damage

There are various signs of damage to this magnetic clutch component, such as:

1. Decreased Car AC Performance

One of the most noticeable signs of magnetic clutch damage is decreased AC performance. Thus, the AC only blows air and does not emit cold air.

2. Sounds Coming from the Magnetic Clutch

Sounds that come from the magnetic clutch can occur when the AC is on and off. When the AC is off, a sound will come out, generally caused by the continuous friction of the pulley rotation.

3. Change in Pulley Color

Another indication is the presence of red or burnt color on the pulley part. This indicates wear caused by repeated slipping. As a result, the edges become red due to heat.

You can check and ensure the damage to this clutch by positioning the ignition key and the AC button in the on position. Later, the magnetic clutch will be supplied with electricity from the car battery.

Then, you can check the electric current. If the center of the clutch is not attracted when supplied with electric current, it can be confirmed that the magnetic clutch is experiencing problems. Another way to do this is by using a test pen.

This test pen is used to check the electric current that will flow in the magnetic clutch. If there is force but the clutch does not work, you should take your car to the nearest workshop as soon as possible.

In addition to understanding the AC magnetic clutch component, you should also know the signs of its damage well. When damage occurs, take your car to an official Daihatsu workshop as soon as possible. With experienced technicians, any problems that occur with your car can be resolved well. Not only that, you can also book online service to avoid long waiting times.
