What Is A Typical Sign That A Capacitor Is Bad Or Has Failed?

Bulging or Swollen Top. Appearance: A bulging or swollen top is the most common and easily identifiable sign of a failing electrolytic capacitor. Normally, the top of these capacitors is flat, but as they fail, the top can dome or bulge outward. Causes: This bulging is typically due to gas buildup inside the capacitor.
