New Range or Wall Oven Door Doesn’t Seal Properly
Door Gasket
With a new range or wall oven the door will close but may appear to not seal properly. It may also seems to stick out more at the top than near the hinges. This is normal.
The gasket around the door or oven opening is brand new and will be somewhat stiff. It is compressed more by the hinges than at the top. After the oven is used several times the gasket will become more pliable and "mold" itself to the door and oven cavity to create a tighter seal. To speed the process the oven may be ran through a short self clean cycle.
Other Causes
On models that have a hidden bake element, the oven floor may slide forward during installation and block the door from closing completely. To correct this, push the oven floor back into place.
