I just installed 2 of the Micro Air thermostats but haven't used them yet. Will be going out in a couple of weeks.
Have you tried rebooting the Dometic Thermostat? You can press the mode button and up arrow until the display reads "--" to reset it. Then press mode again to get going. That may get you running again until you get the Micro Air shipped.
Also you might try just removing the faceplate. If the foam inside gets compressed, it will go wonky like you're seeing as well.
