Tech is called out to the house because of the GSHP not providing heat. Tech immediately determines that compressor start cap is blown and needs to be replaced BUT the original cap has a value of 60mfd and he only has two 30mfd caps on his truck. Not a problem as he connects the two 30mfd caps in parallel to get to the original 60mfd value needed for the compressor. Once connected the GSHP is back up and running. So with the parallel cap configuration, what happens if one of the caps fails (most likely fails open) and that leaves only 30mfd for the compressor to start? How does this effect the long term reliability of the compressor? Are you better off going back after you have the GSHP unit running and replace the two caps with the original single 60mfd cap?
