Carlos, ime there is a very well developed market for counterfeit capacitor= s of all kinds out there. Try to buy the capacitors from a different outlet / brand next time. Also it may be dimensioned too tightly. Carrier is a good brand, I mean the capacitor. Someone suggests to use 2 caps of half capacitance instead of one full sized one. http://www.achrnews.com/articles/84931-the-motor-doctor-diagnoses-motor-cap= acitors With a certain country copying anything anywhere anyhow the problems are really unavoidable. Searching a little with +counterfeit motor run capacito= r will unfortunately yield lots of telltale results: http://www.illinoiscapacitor.com/tech-center/certifications.aspx --=20 http://www.piclist.com/techref/piclist PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
