Desktop Fan That Wont Turn On, Cleaning and Capacitor Replacement

In this repair tutorial, I tackle a desktop fan that completely stopped working, doing absolutely nothing when the switches are turned on. Initially suspecting that the fan's axle just needed a clean and some oil, a deeper look with an ESR meter reveals the real issue is a dead startup and run capacitor. Since a direct 1 microfarad replacement was unavailable, I demonstrate how to wire two smaller 0.47 microfarad capacitors in series to achieve the right capacitance and revive the motor. The video covers the entire process, from diagnosing a stiff spindle to fixing a tricky desoldered wire, and reassembling the fan just in time for the heatwave.
