Hi my name is Robert....

IS the fan for the furnace coming on at all? IS the electrode sparking?

IT sounds like the thermostat is not doing anything at all. On that thermostat if you remove the face there should be a glass fuse, make sure the fuse is good and then I would remove it for 5 mins and see if the thermostat will respond. IF you have power going to the thermostat then it will have to be replaced, click HERE for some troubleshooting, hope this helps some... Robert
