A molded access door assembly for an access opening in a wall or ceiling is provided. It includes a molded frame with a frame channel forming the outside of the access door assembly. The frame channel has spaced apart exterior and interior walls joined at the top edge by a top wall and a lip extending from the bottom edge of the inner wall into the interior of the molded access door assembly to define an opening. The lip provides a stop rest for the door in the closed position so that the door is capable of being attached to the wall or ceiling. The assembly also includes a door having a top surface and a first part of a hinge assembly along one edge of the top surface which cooperates with a matching second part of the hinge assembly along one edge of the frame channel to allow the door to move between an open and a closed position.
