Is the JennAir JOECC327TL a double oven or an oven with a microwave?

It is a combination unit: a microwave sits above a full-size electric oven in one 27-inch cabinet. The two sections run independently, so you can bake below and reheat above at the same time.

What is AirFry on this oven and do I need a separate air fryer?

AirFry is a convection mode that circulates hot air for crisp results on fries, wings and vegetables. It does not replace a basket-style air fryer for small batches, but it covers most of the same jobs in the main oven.

Will it fit my existing 27-inch wall oven cutout?

It is built for a standard 27-inch cutout, but check the exact height and depth against your cabinet opening before ordering. Combo units are taller than a single wall oven, so the opening usually needs to be sized for the full unit.

How does it compare with a 30-inch JennAir combo oven?

The 30-inch version gives you a wider cavity and more rack space. This 27-inch model fits tighter kitchens and is the better choice when the cabinet opening cannot be widened.

Does the microwave need a separate circuit?

No. The combo is wired as one electric wall oven on a dedicated circuit. Have a licensed electrician confirm your existing wiring matches the unit's requirements before installation.

What comes in the box?

The oven unit, oven racks, a microwave turntable and the installation hardware. Trim kits and filler panels for non-standard cutouts are usually sold separately.
