Jen, air gas, downdraft, cooktops
Unfortunately, JennAirs were engineered as an electric range, and the gas cooktops and the dual fuel stove top never really cut it. They all had the problems. Ralph mentioned they were under powered and cooked on evenly. The gas grill feature did not work nearly as well as the electric one either.
Thankfully, the world is moving back to electric ranges.
