johntelling Report post Posted November 13, 2015 Ironically, the RV Comfort LCD display on my coach doesn't display properly when it is cold, so it it almost impossible to set the temperature. I tried warming up the display with a hair drier, and that works, so I know that ambient temperature is the issue. By the way, I live in Sacramento, so 40 degrees is cold for us! Does anyone know if the display can be changed, or do I have to replace the entire thermostat? And if I did, would that solve the problem? Thanks! JT Share this post Link to post Share on other sites
