electure, I didn't think to check the neutral when I had the panel open; from the symptoms, I was absolutely convinced it was just a faulty breaker and replacing it would fix the issue.

Greg, yes, I wired it myself. I can see how your thermostat would cause issues, lol...

Thanks everyone- I'll check it later today and let you know how it goes. Man, I hope it's just a loose screw on the neutral bar, that's such an easy fix... If that fails, I'll throw the multimeter everywhere I can and jumper over that first leg of cable if anything points to damage.
