I already have made the thread "Can a defective DRC [Dual Run Capacitor] on a heat pump cause the fan motor to go bad?" Earlier today I told my father how a defective DRC on my heat pump caused the run winding on my fan motor to burn up. My father asked me if a defective fan motor can cause a run capacitor to go bad, which is the reverse of the topic of my other thread. I don't know enough about how capacitors work to deduce the answer to my father's question.

Can a defective PSC fan motor on a heat pump cause the run capacitor for the PSC motor to become defective? If so, how does a defective PSC fan motor on a heat pump cause a run capacitor to become defective?

Do you have a schematic or picture? Usually caps have ratings, so if it is overcharged or shorted it will fail.

For a Run capacitor, more likely a shorted motor winding would decrease the capacitor lifetime due to the higher current causing a greater temperature rise in the capacitor. This would be a long-term failure, not instantaneous.

A Start capacitor could be subject to a short-term failure by the same reasoning but with a much higher current.

Cheers,
Tom
