Fortunately, a run capacitor that is failing often exhibits a tell-tale clicking noise that you can use to pinpoint the problem. The part may click on start up or on shut down. This is one of the main symptoms of a bad motor run capacitor.
Capacitor Failures
Open mode failure. An open mode failure in a capacitor can have undesirable effects on electronic equipment and components on the circuit. For example, if a large capacitor is used in the smoothing circuit of a power supply, a large wave-like voltage *4 can be converted to a flat DC voltage, but if the capacitor is open, a large voltage wave is …

How To Tell If A Ceiling Fan Capacitor Is Bad (5 Telltale Signs)
If you were hoping to remove the capacitor and just let the fan run on its own that way, you''re out of luck. A ceiling fan needs a capacitor in order to start and run. Without a capacitor, the motor and winding will not have the power necessary to keep the fan running. So, if you have a bad capacitor, you absolutely need to replace it.
Why Do Capacitors Fail? (It''s not why you think)
Capacitors have oil to keep them cool, so they are a bit sensitive to heat. High-voltage surges (transients) can also decrease the life of the compressor, as bridging across the plates can cause premature failure. High voltage, high amperage, and poor capacitor manufacturing are mostly to blame for run capacitor failure.
