What are the causes of capacitor trouble?

Some of the causes of capacitor trouble are listed below. Transient surges, incurred as a result of switching operations, malfunction of associated circuits or components when of sufficient duration and amplitude produce dielectric failure, permanent shift in capacitance, and failure of seals.

What happens if a capacitor fails?

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.

What causes a refrigerator capacitor to fail?

Capacitors fail due to overvoltage, overcurrent, temperature extremes, moisture ingress, aging, manufacturing defects, and incorrect use, impacting circuit stability and performance.
