Thank you KC13 for responding.
Yes it is the display that reads AC. I will try your suggested solutions when
I get home from work today. Would there be a dedicated fuse to the furnace? All other
Power in our home is working? What would cause this to happen(if it is the fuse)?
Currently there is no power getting to the actual furnace from the thermostat control.

Usually the furnace would be on a dedicated circuit. The "AC" displayed means that the thermostat is not sensing the presence of low-voltage power from the furnace. There are several possibilities, but check the basics first (my previous post) when you get home and post back the results.
