9 Causes of Noisy Car AC Blowers and How to Overcome Them
Noisy car air conditioner blowers are a problem that is often experienced in addition to the air conditioner that is not cold enough. The emergence of noise in the car air conditioner will certainly be very disturbing so that it makes the cabin less comfortable.
Moreover, as a car air conditioner component, the function of this blower is very important. Thanks to the blower, the air around the blower can be sucked in. Then, the air is blown into the cabin space through the fins from the evaporator.
This is where the air then releases heat to the freon which has a lower temperature.
Well, when there is noise from the car air conditioner blower, it is certainly something to worry about. Because, if left too long, it can damage other components. In fact, it is not impossible that the car air conditioner is not cold and damaged.
Therefore, it is important to know what causes the car air conditioner blower to be noisy and how to overcome it. Here is the complete information.
the Cause of the Noisy Car Air Conditioner Blower
There are several things that cause the car air conditioner blower to soundand make noise. Here are some of them:
There Is Friction in the Car AC Engine
The first possibility that most often occurs when the blower motor is noisy is due to friction in the car's AC engine.
Pistons that have run out of oil are the main cause. In addition, friction can also occur when the AC engine is worn out because it has been used for too long.
A car's AC engine that is too old will work harder, causing a noisy and disturbing sound.
Oblak Fan Shaft
The sound of the car air conditioner blower is caused because the blower fan shaft is oblique, aka swaying left and right because the screw is loose. If this is the cause, then the car's AC blower will make a grek grek grek sound.
If the axis is blocked, the blower fan will wobble when the blower rotates. This then hits the frame blower causing a sound.
The reason why this happens is due to worn blower shaft and flared bushing or blower shaft retaining housing. The blush component, which is generally made of plastic, is easily deformed.
Worn Blower Bearings
Another cause that causes a car air conditioner blower to make noise is the worn part of the bearing. This is still related to the oblique fan shaft.
The shape of this bearing resembles a ring made of aluminum. Aluminum that rubs against each other for too long will erode one of the metals. This is what ultimately makes the bearing wear out.
Wear that is left too long can trigger a friction sound when the AC blower is turned on.
There Is a Foreign Object in the Car Air Conditioner
Try checking the inside of the car air conditioner, is there a foreign object that enters? If so, this is the reason why the noise from the car air conditioner blower appears.
The things that most often enter are dry leaves, paper, or used tissue that goes into the car air conditioner engine. This object can disrupt the performance of the car's AC engine so that friction appears which as a result can make a noise because it will also enter the blower section.
Dust That Contaminates the Car Air Conditioner
In addition to foreign objects, dust also often enters the car air conditioner engine. This is because the particles are quite small. Even though the car air conditioner is equipped with a filter, dust can still enter.
Well, if this dust will settle on the wet surface of the evaporator and also settle on the sidelines of the blower fan shaft.
This dust deposit interferes with the performance of the fan so that a loud and rough sound appears on the blower of your car's air conditioner.
AC Engine Components That Are Not Installed Properly
Pay attention when you want to install car air conditioning components, especially if you do it yourself. This is because improper and imprecise installation of a car air conditioner can trigger a noisy sound.
The cause of this noise is because there are parts that are still loose. As a result, when the car air conditioner turns on and vibrates, there will be a noisy sound, including coming from the blower.
Leaks, One of the Causes of Noisy Car Air Conditioner Blowers
In a number of cases, a leaking car AC line is also the cause of the noise. This is because when there is a leak, the freon and oil in it will drain quickly and run out quickly.
If the car's AC oil runs out, it will trigger friction in the pistons. As previously mentioned, friction can make the car air conditioner blower sound noisy.
Magnetic Clutch Problem
Another reason why the car air conditioner blower is noisy is because there is a problem with the magnetic clutch. This part is one of the most important components in the car air conditioner because it is the link between the engine and the compressor.
If there is a problem with the magnetic clutch, it can result in reduced performance of the car's air conditioner as a whole, one of which is noise. A damaged magnetic clutch can also cause the car ac not to cool. you know.
Loss of Compression in the Compressor Section
If the compressor part has been hit, then this indicates a fairly severe damage. The main function of a car AC compressor is to pump air from the freon to the condenser.
If the compressor performance weakens, then the air pumped into the condenser will also be weak.
Besides the noise, if the compressor has lost its compression, it can make the car air conditioner not cold at all.
How to Deal with Noisy Car AC Blowers
No need to worry if the car air conditioner's indoor blower fan becomes noisy. There are several things that can be done by vehicle owners to overcome them.
Come on, see how to deal with a noisy and buzzing car air conditioner blower:
- Turn off the blower by pressing the switch on the AC panel
- Open the drawer on the left dashboard behind the drawer to check the blower housing
- See if there is dust, dirt, or foreign matter that is sucked in by the blower and is difficult to get out of the fan. If yes, take it by hand
- If the cause is worn bearings, you can just replace the bearings.
- If the cause is a damaged blower motor, then replace the AC blower motor with a new one.
- Complete the car with an AC filter
- To avoid the wrong partner, make sure you always bring an official car AC repair shop
