In my experience, overheating tends to cause bulk failure of the metalized film capacitors. As pointed out by Marko above, voltage spikes (thunderstorms, heavy duty appliances switching on and off, switching on and off the equipment itself) produce spikes that can damage those caps over time b y reducing the effective capacitance.

The switch is closed, and charge flows out of the capacitor and hence a current flows through the inductor. Thus while the electric field in the capacitor diminishes, the magnetic field in the inductor grows, and a back electromotive force (EMF) is induced in the inductor. Let (Q) be the charge in the capacitor at some time.
