How To Repair The Fan If It Doesn't Work?

The fan cannot rotate due to the lack of oil in the fan. You can use a screwdriver to disassemble the motor and apply some lubricant to the shaft and shaft sleeve. If the fan blade does not rotate due to severe fan wear, you can replace the parts and shaft sleeve to restore normal operation. If the capacity of the capacitor decreases, the fan will not rotate. You can remove the capacitor and replace it with a new one of the same model, which will have a good rotating effect.
