Step 3 · Check Fan Speed Control and Capacitor
Remove the fan's motor housing cover. Locate the capacitor, typically a small black or metal box with wires attached. Inspect the capacitor for any signs of bulging, leaking, or burn marks. If the capacitor appears damaged, it likely needs replacement. Test the capacitor's functionality using a multimeter if you are familiar with electrical testing procedures, though visual inspection is often sufficient for common failures.
