THe AC on your thermostat indicates we are not getting power from the furnace.Most likely causes are power off to furnace, a blown transformer or a blown fuse inside furnace.

Can you give me model on furnace?It will be on a label on inside furnace panel just above burners.Remove panel to burner compartment and look inside. The model number will help me give accurate assistance for your specific unit.

Below is a link showing where to find label with model number:

If you have an electric furnace, label should be on front panel. We will go from here.

I just reset the fuse on the furnace, and she fired right back up. Should be good to go. Thanks
