Mainly this means “gunk” made up of dust combined with typical plant air which usually contains oil, moisture, and metallic particles. This buildup is probably the number one cause of VFD failure! And it''s not the actual dirt itself.
Notes on Capacitors. Capacitors are essential voltage storage units placed inline to an electrical component to ensure a constant supply of energy. This is done through the processes of charging and discharging. If the voltage is too high, the capacitor will reduce it. If the voltage is too low, the capacitor will fill the gap with its held charge.

The capacitor may survive many repeated applications of high voltage transients; however, this may cause a premature failure. OPEN CAPACITORS. Open capacitors usually occur as a result of overstress in an application. For instance, operation of DC rated capacitors at high AC current levels can cause a localized heating at the end terminations.
Recognizing the signs of a failing capacitor and knowing how to test a refrigerator capacitor can be the difference between a minor maintenance task and a costly repair or replacement.

A good capacitor will initially show a low resistance, then increase rapidly as it charges. A bad capacitor may show a low resistance or no resistance at all. Other Signs of a Bad Capacitor: Malfunction of Electronic Devices: Intermittent performance, unexpected shutdowns, or complete failure can be symptoms of a bad capacitor.
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.

Their core functions include energy storage, voltage stabilization, and signal filtering, which are critical for ensuring the proper functionality of electrical devices. Over time, however, capacitors are prone to failure due to various stress factors, leading to performance degradation or system failure.
Generally, a capacitor is considered to have failed when its capacitance drops by 3% or more compared to its initial value. The probability that a failure will occur is called 'failure rate'. There are two types of failure rates: average failure rate and hazard rate (instantaneous failure rate).
In the case of film capacitors, when a local short circuit failure occurs, the shorted area may temporarily self-heal. An open mode failure in a capacitor can have undesirable effects on electronic equipment and components on the circuit.
Capacitors are essential components in almost every electronic device. They store and release electrical energy, helping to smooth voltage fluctuations and power transient events. However, when a capacitor begins to leak, it can cause significant damage to electronic circuits, affecting their performance and lifespan.
