In a previous message, I described a problem with my AC system in that the compressor did not always start - the compressor overload was tripping. I added a Super Boost kit across the compressor run capacitor and this seems to have fixed the problem. I measured the capacitance of the start capacitor at about 90 mf and the label says 88 mf. The Copeland Web site says that the start capacitor for my model of compressor should be about 270 mf. I suspect that the Super Boost unit was adding about 200 mf during start (as measured by my capacitor meter). Should I change out my start capacitor to a 270 mf unit and why would Rheem put a small value capacitor in the unit if Copeland calls for a much bigger value?
