During hot days, when temperatures rise, fans such as pedestal fans, wall-mounted fans, ceiling fans, etc., become indispensable in households. However, have you ever encountered the issue of a fan rotating slower than usual despite setting it to the highest speed? If so, read this article immediately to understand the reasons behind it and how to resolve this issue.
1. Dust Accumulation on Fan
After extended use without proper cleaning, fans tend to accumulate a significant amount of dust, affecting their rotation speed. This leads to weaker airflow and discomfort during usage, resulting in the fan rotating slowly.
Solution:
To ensure the smooth operation of the fan motor and to provide cool air, users should regularly clean the fan at least once every 1 to 2 months. The process involves disassembling the fan to remove the fan blades, the fan cage, and the motor housing, then wiping off any accumulated dust.
2. Fan with worn-out motor and dry bearings
This is a common cause for fans to spin slowly and emit uncomfortable noise. It could be due to the fan running dry, increasing friction causing the motor's silver-coated bearings to wear out, or the fan spinning slowly. To diagnose the cause more thoroughly, turn off the fan and remove the fan cage. Then, use your hand to manually spin the fan blades. If the fan spins but then stops abruptly, it can be concluded that the fan has a worn-out motor with dry bearings.
Solution:
Remove the fan casing and take out the fan control box. Use a soft cloth to thoroughly clean off all the dust and dirt accumulated on the fan blades. Next, apply a few drops of lubricating oil to the bearing. If you lack experience in fan repair, take it to authorized service centers for assistance.
3. Faulty electric fan capacitor
Even after users have cleaned the fan thoroughly and applied oil to the bearing, if the fan still spins slowly, it means the capacitor is faulty. Since the capacitor plays a crucial role in determining the fan's rotation speed, a faulty capacitor will result in the fan spinning very slowly or not functioning at all.
Solution:
Purchase a new capacitor with the same voltage and capacitance rating as the old one to ensure stable fan operation. Alternatively, seek assistance from skilled technicians for fan repair.
4. Damaged copper winding of the fan
If none of the above causes are correct, the reason may be a broken copper winding of the fan due to long-term use.
Solution:
Take the fan to authorized repair centers for assistance. You can also replace the fan's copper winding. However, be sure to carefully follow online guides to perform accurate and safe winding replacement procedures. If you lack deep knowledge of electricity, it is not advisable to attempt fan repairs at home.
