When you say a Duo-Therm register, do you mean thermostat? If not, then as suggested, check furnace for loose, disconnected or crushed duct. Some ducts also have a way to turn them off at the outlet. Mine have a small round knob and when turned shut them off/on.
I suspect however you have 2 thermostats. The rear would control a rear furnace perhaps AC too. That tstat would of course have to be on,set to furnace and set to proper temp.
More info is needed to properly direct you.
