Does the furnace turn on when you set it to heat with the thermostat hooked up to the jumper wire? I would imagine the red wire would be supplied by the furnace considering that is a 12volt device. If the furnace not working may need to be reset? - that may fix the problem of no power to the thermostat. Can't say for sure but grasping for straws at this point!
