It's 26 quarts but the rack feels too small. Why?
Because volume and usable cooking area are different measurements. The 26-quart figure describes the whole interior, and a tall interior is what lets Emeril promise room for a rotisserie chicken or a 12-inch pizza, both of which need height or diameter rather than shelf space. But most of what people cook needs flat area on a rack, and the rack's size is set by the width and depth of the cavity, not by its height, so an oven can be large in volume and still give you one tray's worth of crisping surface. Crisping needs hot air to reach every surface, so food must sit in a single layer with space around it however much volume the oven has.
Can I cook on two racks at once to fit more food?
For baking and roasting, yes: a second rack works there because even heat is enough and both trays warm through. For crisping, no: the upper tray shields the lower one from the airflow that does the crisping, so a second rack of chips or wings underneath will come out soft. Plan for one crisping tray at a time and use the extra height for taller items like a chicken or a pizza instead.
My oven smells or smokes after a few uses. What should I clean?
The cavity roof and the heating elements, which is the job most people skip. Fat driven off food during cooking travels upward and bakes onto the elements and the roof of the chamber, then smokes on later runs, and washing the accessories does nothing about it. Unplug it, let it cool completely, and wipe the roof and the visible element surfaces gently and often. Clean the accessories that touch food after each use too, since baked-on grease on a rack is far harder to shift once set.
Should I be careful with the French doors?
Yes, a little. The two doors are linked so they move together, and that linkage is a moving part a single hinged door does not have. Open them fully rather than partway, since they can swing back, and never hang a tea towel over the handle, since the extra weight works against the mechanism every time it opens. Treated normally the doors are fine, but they deserve a gentler touch than a conventional door.
Will it actually replace my toaster and my air fryer?
For most households, yes, and that is the case for buying it. The toast function counts down and switches off by itself rather than relying on you watching it, though anyone fussy about toast may still prefer a pop-up toaster. The wide temperature range covers everything from dehydrating at 75°F to hard browning at 500°F. The trade is counter space: at 16.9 inches deep and needing clearance above and behind, it is not a small appliance, so measure your worktop before assuming it replaces two smaller devices.
Is reliability something to worry about?
Worth factoring in rather than dismissing, but not disqualifying. Most units serve their owners well, and reliability is uneven rather than poor. For an appliance with a fan, a touchscreen, linked doors and several heating elements, some spread in how long units last is unsurprising. Buy from a seller with a straightforward returns process and use it properly in the first few weeks rather than saving it, which is sound advice for any appliance of this kind.
