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.

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 …
Air Conditioner Capacitor Keeps Failing [SOLVED]
Bad Ac Run Capacitor Symptoms. Having a bad AC run capacitor can cause several symptoms, including delayed fan start-up, noisy operation, and reduced cooling efficiency. Additionally, you may notice that the compressor motor has difficulty starting, or it will hum for a few seconds before tripping the circuit breaker.

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.

8.2: Capacitance and Capacitors
Capacitors are available in a wide range of capacitance values, from just a few picofarads to well in excess of a farad, a range of over 10(^{12}). Unlike resistors, whose physical size relates to their power rating and not their resistance value, the physical size of a capacitor is related to both its capacitance and its voltage rating (a consequence of Equation ref{8.4}.
