A combined microwave and electric heating oven including a damper mechanism for selectively and automatically introducing a forced air flow into an oven cavity. A timer is provided for determining a microwave cooking period, wherein a magnetron is energized to perform the microwave cooking operation. The damper mechanism is associated with the timer so that the damper is placed in a first condition wherein the forced air flow is automatically introduced into the oven cavity, when the timer is wound up to select a preferred microwave cooking period. When the preselected time period has been counted by the timer, the microwave generation is terminated, and the damper is placed in a second condition wherein the forced air flow is automatically never introduced into the oven cavity. The damper is placed in the second condition when the electric heating cooking is performed, whereby the interior of the oven cavity is maintained at a high temperature.
