Although it has shape keys which you might want to remove before doing more edits. Moving and scaling stuff would get stored in the key(s), changing the geometry can break the shape keys, and there is something to change;
Selected in the screenshot is an interior face, a non-manifold mesh error, because it can be a part of several surfaces instead of one. If you want the geometry connected with the door face, it should have thickness and connected just like the sides. Although, it’s a separate part in all fridges I’ve seen.
