    Your wiring looks correct, did you wire this live or did you turn off the power first? If you didn't turn the power off you may have blown a fuse or let the smoke out of something. If you put the...

    Those pictures don't help. I will say that your furnace (by the looks of it, a Goodman GMP series) IS capable of running a five wire thermostat BUT these are not wired directly to the control board....

    It's possible. I replaced a heat exchanger in a furnace only to have the gas valve fail when I started it back up. It's rare but it happens.

    Is the common connected on your NEST? They tend to cause goofy stuff like this when they are power stealing. Take the NEST off and put a real thermostat, I bet it stops doing that.

    Judging by the gas valve, that unit is from the late 50's to early 60's. Coleman floor furnace. Probably should be replaced.
