Also check the AC (LEFT) side of the high-limit switch in the thermostat stack.
Press (lightly) the button behind the rubber circle.
If that does not work, remove the rubber cover and EXAMINE the thermostat.
This thermostat has a burned connecting wire between the high and the low limit bellows switches.
