Over the years I've had a couple of motor-run capacitors fail. A plastic cased one had some grey gunk come out of it. Recently I had an aluminium cased polypropylene film capacitor fail, and drop to <10% of its rated capacitance. When I opened it up, there was what looked like lumps of silver grey plastic that had melted, flowed to the bottom of the casing and solidified.
I was just curious as to what is actually going wrong in these capacitors.
Also, the latest one was on the refrigerant compressor of a heat-pump tumble dryer. Would I get better capacitor life and / or lower power consumption if I arranged the the capacitor disconnected after the heat pump started?
