How to care for your floor fan

In hot weather, even an ordinary floor fan can be a real lifesaver. Despite the relatively simple design, this technique requires periodic maintenance. It’s good that doing this is not at all difficult and even beginners can handle it with the simplest tool. We will tell you in detail how and why to do this.

Do fans need cleaning?
Dirt on the external structural elements is not a critical breakdown, but it causes several inconveniences. Firstly, it spoils the appearance of the equipment and over time it becomes more difficult to eliminate pollution. Secondly, dust often settles on the fan blades, which, when layering, is carried throughout the room by an air stream. This can be critical for allergy sufferers.

In the worst case, dust or fine threads can get caught on the moving parts, causing the fan to stop spinning completely. In order not to bring it up to this, we recommend to monitor the appearance of the device – cleaning the structure does not require much time and effort.

For clarity, we will perform cleaning using a typical Vitek 1909W floor fan as an example.

The described instruction is quite suitable for other similar models.Cleaning the grate and blades
Although most floor fans have a typical design, we recommend that you read the technical manual. In it, you will find out exactly how and in what order you need to dismantle all the elements. For example, in the model under consideration, the entire structure consists of 16 elements. We will only work with parts numbered 5-10.

Before cleaning, be sure to disconnect the device from the power supply!

The first step is to dismantle the protective grill. Usually its halves are held by a special tightening tape, in the diagram it is number 10. To remove it, you need to loosen the fastener – you need a regular Phillips screwdriver. Loosen the screw until the ring tension is loose.

Remove the tightening ring carefully while holding the front of the protective grille.

Next, you need to remove the blade block (number 7). It is secured with a central plug (number 9). You can unscrew it with any hard and thin object, for example, a metal ruler or knife. Please note that the parts usually have inscriptions that explain which way to turn. In our case: TIGHT – twist, and LOOSE – twist.

While holding the blades, unscrew the center piece.

By unscrewing the cap, the blades themselves can be removed. After that, you need to screw on one more fastener (number 5) that fixes the rear protective grill. Also pay attention to the labels that tell you which way to turn the part.

You now have all the basic details at your disposal. You can start cleaning.

If the contamination is small, then the blades, plastic parts and gratings can be treated with the most common damp rags, after which all surfaces can be wiped dry.

Do not bend the blades, otherwise you may imbalance the balance.

If there is abundant contamination or you do not want to manually wipe each bar of the grate, then all the parts can be soaked in a large container, filling it with warm water. Additionally, you can use ear sticks to clean out dirt from hard-to-reach areas. For plastic parts, you can use a mild detergent or alcohol. The latter is recommended by the designers themselves in the technical manual.

If there are already traces of rust on the metal grill, you can use a glass or toilet cleaner. Apply the compound to rusty areas for 3-5 minutes, then wipe with a damp and dry cloth.

Do not use strong solvents to clean plastic parts.

All parts can be soaked in detergent solution for 7-10 minutes, then wiped dry and left to dry for several hours.

Do not forget to inspect the shaft itself – dirt and small debris can also accumulate in the inside. Remove them with tweezers.

Once cleaning and drying are completed, it remains only to assemble the fan in reverse order, checking its functionality.

Important nuances
To make the whole process go without force majeure, we recommend that you adhere to a few simple rules during disassembly, cleaning and assembly of the fan:

Do not apply excessive force to the plastic parts – they can crack or deform, and in the worst case, you damage the threads.
Do not rotate the upper fan assembly when it is off – this may damage the mechanism, which will prevent the head from rotating smoothly after being turned on.
Do not use abrasive brushes. They can not only spoil the appearance, but also impair the airflow from the blades.
Do not let water get into the head with the electric motor. If you are going to wipe the housing or shaft, then do it only with a dry cloth.
Do not run the fan without protective grilles – many will want to check if everything is working before final assembly.
Disassembly is most convenient when the fan is on a stand, as this will allow you to adjust the height to suit your height.

What to do if the blades or top block won’t rotate
The most common failure of a floor fan is that it has stopped rotating. There may be several reasons for this:

dried grease or lack of it;
dry condenser;
short circuit or broken wires;
mechanical displacement of the motor shaft.
Three of the four reasons are difficult to eliminate on your own – here we recommend contacting professionals. However, experienced users can update the lubricant themselves, for this they will have to get to the electric motor by disassembling the case of the upper block.

If only the fan head does not rotate for you, then inspect the integrity of the gearbox. It is a small rotary mechanism consisting of two fasteners and a metal rail. The plastic may crack, which will simply detach the guide.

To renew the lubricant, you will have to dismantle the gearbox. This will allow you to gain access to the bearing and then remove any dirt from it and lubricate it if necessary.

Any good quality penetrating lubricant will do, and prepare WD40 as well. It is best to apply the composition using a special nozzle, which will allow the lubricant to be driven into a narrow space. Excess or dirt can be removed with a cotton swab or stick.

After completing all the work, you can assemble the structure. This is an operation for experienced users who have disassembled some household appliances not for the first time.

All other malfunctions can be diagnosed only with specialized equipment. For example, a multimeter will be required to check the capacitance of a capacitor. A typical sign of loss of capacitance is a drop in fan speed. If you are going to change the capacitor yourself (soldering is required), then you need to buy an identical one or an analogue with the same parameters for replacement.

Now you know not only how to clean the fan structure, but with a certain skill you can even lubricate the bearings. And if you don’t have a fan yet, it’s time to choose!
