The Stove is a role-play item. The door can be opened in Fancy Furnishings but a bug does not allow you to open it on your base. This could be the same reason that the right door on the Refrigerator does not open either.
The Stove, just like the Refrigerator, dishwasher, etc. is used as a small type of storage, mainly for axes or other loose items such as the Lump of Coal. It can be used as a decoration for your base. The stove itself has no use, and cannot be turned on, it is only used for cosmetic purposes.
