Review: Identical to the original and saved the day. - My pool pump quit. It kept popping the breaker. After a little research, it seemed the starter capacitor was the most likely culprit. Replaced the original with this and viola! All is well. A note of caution. Replacing capacitors can result in a VERY nasty shock. If you're not sure what you're doing, don't do it and get an electrician to replace it for you.
Review: Works great - Works great so far. Pool pump was humming and not starting. Replaced this $16 part and it started right up and ran quieter.

## Questions & Answers

**Q: What size SSP hard start kit?**
A: Only use a hard start kit if it's old and staring. They come in a range of sizes.

**Q: will this work for replacing 97F9899 Genteq Capacitor?**
A: The capacitor is a 45/5.  The 45 for the hermetic and 5 for the fan.  The voltage should be in range.  The number should be on your old capacitor.  The data I have states that it will work.

**Q: My old capacitor has a 5% tolerance rating. Can I replace it with this one which is rated at 6%?**
A: The tolerance rating is not as important as the voltage rating. Your 220VAC system can be as high as 230VAC. The tolerance is referring to the amount of farads, which will make your motor run faster or slower.

**Q: USA made**
A: No
