How could you repair an electric fan that is not working properly Apply a scientific method?

To repair an electric fan that is not working properly, first observe the fan to identify the issue, such as unusual noises or lack of movement. Next, formulate a hypothesis about the potential cause, such as a faulty motor or a blocked blade. Test this hypothesis by inspecting the fan for obstructions, checking the power source, and examining the motor and wiring for damage. Finally, analyze the results of your tests and make necessary repairs, such as replacing broken components or cleaning the fan, and then re-evaluate its functionality.
