Wide does not mean tall. The HDS8657U puts a gas cooktop over a 3.2 cu ft electric oven in a 36-inch freestanding dual fuel body from the 800 Series, and the cavity is broad and shallow. Baking sheets and roasting trays fit it nicely, while tall items are a tighter match. What you gain is shelf area, not headroom, and it is better to understand that before buying.
A wide cavity also asks more of the convection fan, which has to even out heat across the whole width. When baking comes out uneven, the fan or the door seal is usually responsible, not the oven design itself. The door is heavy as well, so its hinges carry a lot of weight and eventually lose tension.
On a visit, we check the seal, then the fan, then the hinges. Measure a tall roast against the cavity before you plan a holiday meal.
Measure first. These ovens are wider than they are tall, so a big bird may touch the top rack or the ceiling of the cavity even when there is plenty of side room.
Not when the convection fan is healthy, since that is its job. Uneven results across the width usually point to the fan or the door seal.
They carry the weight of the door and keep it balanced as it opens and closes. When they wear, the door drops, sticks or no longer closes flush, and they are replaced as a pair.
