Has the fan started making knocking noise? Technical glitch or your mistake, know how to fix it in minutes

In summer, if the fan suddenly starts making a whirring or rattling sound, then most people ignore it. But this small problem can increase huge expenses in future. In many cases this problem can be easily fixed at home. If you take action at the right time, huge expenses on fans can be saved.

Why does the fan make rattling sound? There can be many reasons for the noise of the fan. The most common causes include loose screws, bent blades, or friction in the motor. Noise can also occur due to accumulation of dust and not cleaning for a long time. Sometimes the fan gets out of balance, causing vibration and rattling noise. Therefore, this voice should not be ignored.

First of all, check the screws and fittings: If the fan is making noise, first check its fittings. Sometimes the screws of the blade or cover become loose, due to which noise occurs. Lightly tighten all the screws with the help of a screwdriver. Keep in mind that excessive tightening can damage the threads, this is the easiest and effective solution.

Cleaning and balancing of blades is important: Accumulation of dust and dirt spoils the balance of the fan blades. In such a situation, clean the blade with a dry or slightly wet cloth. If a blade is slightly bent, straighten it gently. When the balance is correct, the vibration reduces and the sound stops automatically. It is beneficial to do this maintenance every few months.

Understand the need for oiling in the motor: In old fans, friction increases due to drying of the oil inside the motor. Due to this the fan starts making whirring or rattling noises. In such a situation, it is beneficial to add lubricant or machine oil of the right grade. But if you are not experienced, it would be better to take the help of a technician, so that there is no damage to the motor.

When to call an expert: If the sound does not stop even after tightening the screws, cleaning and oiling, then the problem may be in the motor or bearing. In such a situation, running the fan again and again can cause great harm. Therefore, get it checked by a trusted electrician. By getting the repair done on time, there is no need to buy a new fan.

Regular maintenance is necessary: ​​Periodic cleaning and checking of the fan significantly increases its life. If maintenance is not done, even a small defect can become a big problem. It is considered a wise decision to check the fan once every 3 to 4 months and get it serviced at least once a year.
