I have a model 143-841550 cast iron stove that a previous property owner bought from Sears. The stove is fully cast iron, i.e. no glass in the door. The handle to open the door rotates 360 degrees with releasing the latch. Has anyone experience this or something similar.? The door opens down so it can't be lifted off the hinge pins. There seem to be pins in the cast iron casing at the bottom on each side.
