hi i am dan i can help you with this. i assume you are refering to the display on the thermostat? if that is the case most likely it is a problem with the thermostat. first thing to try would be to reset the thermostat by removing the batteries and if they are over 1 year old replace them or if newer you can reinstall the same batteries afte 1 minute. if it does not have batteries turn the power off to the furnace for 1 minute and then back on and check to see if it works.
