Does the no-preheat mode really work?

Yes. It lets you start baking without waiting for the oven to preheat, which owners say works well for items like casseroles and frozen foods. Delicate baked goods still do better with a full preheat.

Is this range self-cleaning?

Yes. It has a self-clean cycle that burns off food residue at high heat. You still wipe out the ash afterward.

Does it have convection?

No. It is a standard gas oven without a convection fan, so heat comes from the bake and broil burners only.

The oven is 5.0 cu ft, large enough for a turkey or several baking sheets at once.

Does it need a special gas line?

It runs on natural gas and needs a standard gas hookup and a 120V outlet for the ignition and controls. Conversion kits for propane are typically available from Whirlpool.

Is it worth it over a convection range?

If you mostly use the stovetop and want self-clean without extra features, it covers the basics. If even browning and faster roasting matter, a convection model is the better fit.
