Hi Lisa! This model has 2 very similar options, Timer On/Off and Cooking Time. The Timer option is only a kitchen timer and does not affect the operation of the oven. The Cooking Time feature does control the cooking time of the oven compartment. Another notable feature of the range is that once the oven has been in use, the cooling fan will continue to run, even after the oven is shut off, until the oven compartment is cooled down. ^Jecca
