Your lazy start may be due to other factors and you might kick out the thermal overload or do other damage **Q: is thi capacitor will replace 370vac 70uf +/- 10% 50/60hz 70*c ?** A: You have to replaced with same size in all ways. **Q: How do you get warranty service?** A: Most capacitors are only warranted for 1 year. I suppose you would have to contact the capacitor manufacturer. **Q: is this the same as a 70/5 capacitor?** A: No! A 70/5 capacitor has three terminals on the top. This capacitors used for the compressor in conjunction with a smaller capacitor for the fan. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Capacitor 55 uF bipolar *by R***W on July 18, 2025* Perfect, the size was correct. I used it in our swimming pool pump. It works really well. I even bought another spare just in case. ### ⭐⭐⭐⭐⭐ Perfect Fit *by J***R on April 23, 2026* Perfect fit for a Century/AO Smith 2 hp pool pump J Frame motor where the capacitor is mounted inside the rear cover. ### ⭐⭐⭐⭐⭐ Just what I needed, and it fixed the problem! *by J***I on August 10, 2023* Great product, our AC unit went out and the compressor would not start other than tripping the breakers. We tested the start capacitor and found it not within specks. We ordered this one as it was the same as ours, and it worked beautifully as our AC unit works just as it should.
