Burning through capacitors on pump motor?

[Benji]

Good day all-

I moved into this house less than three years ago and I just changed out a capacitor on the pump motor for at least the third time, maybe the fourth. Luckily, I am a little bit excessive and stock extra capacitors for pool pump and hvac system and reorder as soon as I replace, but this seems like an excessive amount of replacement.

Granted, the capacitor is mounted to the motor and has some sun exposure in Houston sun / heat but it still seems like they are blowing too often. I have my pump set to run about 2 hours twice a day. I did run it for about 2 days straight recently though.... my stabilizer disappeared on me with all the rain and i got a tiny bit of algae and backswimmers, so I corrected cya level, slammed it, and let the SWCG run on high for 48 hours or so.

Is capacitors blowing a sign of some other issue with the pump motor or problem in the system somewhere? Or is it just attributable to texas heat and my long run time?

Are you also going through capacitors on your HVAC?

no, not really. one on the old outdoor condenser that was who knows how old since moving in. i have just been stranded on a holiday weekend in the past at an old house not being able to get my hands on a replacement capacitor. ever since i stock my own replacements for important equipment considering they are cheap and critical and common failure point. esp with the pool being dependent on working pump as chlorine source.
