Cracked or Broken Casing Visual Clues: Physical damage to the capacitor''s casing, such as cracks or splits, is a clear sign of a problem. This can be due to mechanical stress, overheating causing the casing to burst, or manufacturing defects.
When the operating voltage of a capacitor exceeds its nominal value, it will lead to the breakdown (of insulation) between its plates. As a rule, this results in mechanical damage, but not always. You can check whether there is breakdown when measuring resistance.

If the "15V" comes straight from an unregulated rectifier, e.g. from a mains transformer, then it''s not really 15V even if an RMS voltmeter indicates so - the peaks are higher, and as the capacitor ages and loses capacitance and gains ESR, the ripple will only grow

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 directly applied to the circuit, which …
