This is not to be confused with how heat affects capacitors. High operating temperature can, over the long term, cause the electrolyte to more quickly evaporate or boil out. Figure 7 – Inverse Relationship Between Run Temperature and Capacitor Life
Run capacitor hot to the touch | DIY Home Improvement Forum
An ideal capacitor would never heat up, but real world capacitors have internal resistance. I guess one failure mode for these caps would be an increase in internal resistance. Each 10C increase in temperature halves the life of insulation and I assume this also applies to caps.
The Impact of a Faulty Capacitor on Your HVAC System
Capacitors may seem like an insignificant part of your HVAC System, however, if you have a failing AC capacitor, your unit will not be able to properly turn on as it was designed to. By understanding how capacitors work and the value in replacing them when it is needed, you can ensure that your home in the Sacramento area has a unit that …
