Introduction

If your floor fan is not spinning properly or making unusual noises, this guide will help you repair it by replacing the rotor. A damaged rotor can cause reduced airflow, overheating, or complete fan failure. Before starting, check for any loose screws, dust buildup, or obstructions in the blades. Make sure to unplug the fan before beginning the repair process.

Unplug the fan from any power source before starting the repair to avoid electric shock.

Some internal components may have sharp edges. Handle parts carefully to prevent injury.
