Even if the appearance of the failed capacitor is not abnormal, care must be taken when handling the capacitor. In particular, take care to avoid electric shock *1 due to residual charge on the capacitor, contact of electrolytic solution *2 with the skin or eyes, and inhalation of electrolytic solution vapors.
Power Failure: Capacitors are crucial for smoothing out voltage fluctuations in power supplies. A failed capacitor can lead to power failures or, in severe cases, damage to the power supply. Audio Noise: Audio equipment capacitors are used for signal coupling and noise filtering. Failure can introduce noise or distortions in the audio output.
Diminished electrical performance is a common sign that a capacitor is not working properly. This can manifest in various ways, such as reduced power output, flickering lights, or unexpected device shutdowns.
Discharge the capacitor fully using a resistor or a dedicated discharge tool to neutralize any residual charge. After confirming the capacitor is safe, remove it from the circuit, ensuring that the replacement capacitor matches the original specifications for voltage, capacitance, and tolerance.
The capacitor may be worn out, and continued use without replacement may result in an open failure or short circuit. Snap mount type aluminum electrolytic capacitors are used in power supply devices. The heat sink and the top of the capacitor were placed close together to reduce the thickness of the device.
Use low leakage capacitors where appropriate to reduce the risk. Periodic Maintenance: Regularly check capacitors in critical systems, such as motherboard capacitors, to ensure they are not leaking or failing. Proper Storage: Store capacitors in a cool, dry place and avoid exposure to extreme conditions.

Do electrolytic capacitors expire if unused? : r/AskElectronics
I don''t remember where I read it or heard it, but I remember learning that electrolytic capacitors, if not used in a circuit, will die because the electrolyte dries out. It takes some number of years. Interestingly, if they are used in an operating circuit, the electricity keeps them from drying.
What happens when electrolytic capacitors ''dry out''?
The mechanism by which an electrolytic capacitor "dries out" is that the water in the electrolyte evaporates. This is just like the dregs in a bottle of beer drying out, only with quote marks (and without the mold). This "drying out" happens because all …
