Sensor Cooking
The Sensor Cooking function uses a special gas sensor that detects both humidity (steam) and hydrocarbons
(food odors) during the cooking process. Before conducting either of the sensor tests below, ensure the unit is
plugged into a wall outlet for at least 5 minutes. Do not power the unit during the 5 minutes. If unit is already
plugged in, proceed. The gas sensor is a plug-in device located in the vent area at the top, left-hand corner of
the cavity behind the grille.
