Alright first a few things.
Check batteries on thermostat.
Check the switch at the furnace to make sure its in the ON position.
Sometimes you can look on the lower half of furnace you will see a small red light/green light if you can see this please count the number of times it flashes also...... I hate to say it but im thinking that thermostat failed. But let me know, Unfortunately I will be heading to work but I will try to answer when I can :) Lets get this fixed!
