X 2 on the capacitor but, in my case on the Carrier Air V, the only indication was what looked like, at some point, a little oil leaked out of it. Other than that, it looked fine. Sometimes it buldges out when it blowes but my didn't.. Anyway, that electrical smell is what I experienced, also. The blower will work on "Fan" but nothing else.
Careful, capacitors are nothing to mess with without reading up on the subject. They store a charge that will get your attention.
