The invention is for an enclosable evaporator/defroster unit for a refrigerated display case. The refrigerated display case has a cabinet with a floor, a ceiling, a front wall, a rear wall, and side walls. There is an access opening in one of the front wall, the rear wall and the side walls. An air duct extends around the cabinet for conducting a current of air. The air duct forms a substantially closed conduit. There is a gap in the conduit that coincides with the access opening in the cabinet. A fan circulates air in the air duct. An evaporator coil is positioned in the air duct to cool the circulating air. A defroster unit is also positioned near the evaporator coils to melt the condensation on the evaporator coil. The defroster unit has a heater, dampers, and an actuator for moving the dampers between an open and a closed position.
