The wires going to the screw terminals at the air handler look thicker than the ones going to the thermostat, are you sure they're the same wires, or are they spliced together somewhere in between? In that case the colors may not be consistent from one end to the other.
You are correct and I noticed that too. They are spliced but they are spliced to the same exact color, I just didn’t look for the orange cable, so I don’t know where that is going
I ask because if the B terminal on your old thermostat was really wired to the C terminal at the air handler, then if the thermostat ever energized the B output it would be short-circuited and might've blown a fuse or damaged the thermostat. That's why I was wondering if the colors might not match up.
