ABSTRACT OF THE DISCLOSURE A combination microwave and electric oven includes 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 automatically placed in a first position wherein the forced air flow is 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, micro- wavegenerating is terminated and the damper automatically assumes a second position wherein the forced air flow is prevented from entering the oven cavity. The damper is placed in the second position when electric cooking operations are performed so that the interior of the oven cavity can be maintained at high temperatures without excessive energy consumption.
