How to replace bearings in vacuum cleaners Lg and Samsung by yourself

Nowadays, it is essential for every household to have a vacuum cleaner. Modern consumers tend to opt for top-notch models manufactured by well-known brands like Lg, Samsung, and others due to their sleek design and outstanding quality. However, even the most reliable appliances can experience malfunctions and cease to function properly. In such situations, it is advisable to seek assistance from professional service centers. However, if the issue is minor, it may be possible to fix it on your own. For instance, you can replace the bearings in a Samsung vacuum cleaner without professional help. Let us explore the steps involved in this process.

Principle of operation of vacuum cleaners

All Lg and Samsung vacuum cleaners operate using a similar basic mechanism. These models are equipped with inertia air pumps that are powered by a brushed electric motor. This motor, as well as the flow of air, pulls in dust and small debris. The particles then collect on the filters of the device and, after passing through them, gather in special dust containers, which need to be cleaned regularly (more information on the internal structure – the device of the vacuum cleaner: main components, classification). Additionally, most Samsung vacuum cleaners feature various functions and components, including:

• An air flow regulator.
• A dust bag fill indicator.
• A motor power regulator.
• An automatic shut-off feature when the dust bag is full.
• An automatic cord retraction system.
• Pushing refuse.
• An enclosure for concealing the power cord, which can range from 3 to 5 meters in length.

Causes of breakdowns and their elimination

There can be various factors that can lead to malfunctions in Lg and Samsung vacuum cleaners, such as:

1. A common issue is a problem with the cord. Usually, the electrical part of the appliance is located behind the fan. It is crucial to inspect the cord for any damage to its outer sheath or the current-carrying conductor.
2. Another problem could be related to garbage collection. For instance, the Samsung vacuum cleaner may work and provide normal suction, but it may collect garbage poorly. One possible cause for this issue is the jamming of roller bearings. To confirm this, it is necessary to remove the brush roller and unscrew the end caps. These end caps should be free from any debris, threads, or hair. If there is any present, it should be removed.
3. The malfunction of the Samsung vacuum cleaner motor can also be caused by the bearing itself. If you hold the device’s motor in your hand and gently shake it by the anchor, you may notice that with faulty bearings, the shaft will also move from side to side. In this case, it is necessary to replace the bearings.
4. If there is a smell of burning rubber, the bearings may also be the culprit. In this case, check the brush roll for free rotation. If the rotation is tight, then in most cases, replacement is necessary. You can try lubricating them first, but if this does not solve the problem, replacing the bearings is inevitable.

If your Samsung, LG, or any other vacuum cleaner brand starts to hum loudly and "roar," it indicates that the bearings are faulty. Only attempt to replace them yourself if you have experience in repair work.

Where to start with repairs

Despite the exceptional quality, user-friendly interface, and effortless maintenance of the vacuum cleaners produced by Korean corporations Lg and Samsung, no one is exempt from encountering occasional breakdowns and malfunctions.

The process of self-repair for vacuum cleaners, including models made by Samsung, commences with disconnecting the device and detaching the casing.

1. Take off the filters that block access to the motor.
2. Loosen and take out the screws holding the motor housing.
3. Detach the motor from the housing.
4. Disassemble the fan mechanism.

How to replace the bearings yourself

To replace the bearings in Lg and Samsung vacuum cleaners, you will need to follow these steps:

1. First, remove the brush assembly and then unscrew the screws that hold the device’s body in place.
2. Gently remove the motor covers using a screwdriver and a small hammer. Be careful throughout this process to avoid damaging the motor winding.
3. Take extra caution while removing the old bearings from the armature shaft.
4. Using a small hammer and a tube with the appropriate diameter, carefully install the new bearings in place.
5. Finally, reassemble the motor of the vacuum cleaner in the reverse order of the previous steps, whether it’s a Samsung or Lg model.

Diagnosis of the motor

There are several potential causes for the vacuum cleaner to stop working:

1. One possible reason is that the collector has overheated, caused by sparking or physical damage to the bearings.
2. Another possibility is insufficient ventilation, leading to the motor overheating.
3. Water may have entered the engine, causing a short circuit or corrosion on its components.

If the fan impeller is undamaged, it may be possible to repair the engine. However, if the impeller is damaged (often due to foreign objects), it will be necessary to replace the motor with a new one.

While it’s true that not every kind of malfunction can be fixed by yourself, it’s always a good idea to reach out to the experts at Lg and Samsung service centers if you’re unsure. They can provide you with professional advice and, if needed, replace the bearings and motor with genuine spare parts.
