Q:How long should my run capacitor last?
A:The mid point for a good quality aftermarket (a capacitor that didn't come with your motor) run capacitor would be 30,000-60,000 running hours. Factory installed run capacitors sometimes have a designed lifespan of much less that this. In highly competitive industries where every part can have a significant impact on cost, or where a motor's intended use would likely be intermittent and infrequent, a lower grade of run capacitor may be selected with a design life of as little as 1000 hours. Additionally, all of the factors from the section above (run capacitor causes of failure) may dramatically modify the reasonable expected life of a run capacitor.
