I love the french door oven, but the burners are pretty bad. The non-20K burners maintain high burn until you almost reach low. Only the last 20% of the know rotation is used to lessen the flame. I contacted support, sent them a clear video, and they told me that it was doing what it was designed to do. I told them that it was a broken design if medium on the knob isn't medium flame. They essentially told me to deal with it. The 20K burner is only slightly better because it has a separate mid point for when the main burner turns off.
We purchased this range because we wanted a gas appliance and the French doors make it easier for the baking we do (nearly every day). Love this thing!
