My A/C unit went out about a month ago and the technician diagnosed the problem as a bad half of the dual capacitor (the fan side I think). He didn't have the correct capacitor to do a swap, but he did have one that he could install that he said would substitute for the bad half of the original. He installed the new capacitor and things went along fine until last Wednesday when, I believe, we lost the other half of the original capacitor (similar symptoms, intermittent buzzing sound, A/C stopped working). I ordered a replacement for the original dual capacitor and am preparing to install it myself only I'm not exactly sure how to do it. I'm assuming I can just move over the wires that are still connected to the original cap to the new one, but I'm not sure where the blue and yellow wires would go. I have included some images that I hope will allow someone to help me. The pic showing the blue wire is the new capacitor that was installed that I hope to remove. The other pic with the yellow, orange and red wires is the original capacitor that I want to replace. I have also included a pic of the wiring diagram. Thanks!
