1. An airflow control system for an oven having an oven cavity partially bounded by a rear wall, a first side wall, and a second side wall, the first side wall and the second side wall being parallel, the airflow control system comprising:
a baffle housing disposed in the oven cavity, the baffle housing spaced from the rear wall and extending to, but not intersecting, the first side wall and the second side wall, the baffle housing being spaced from the first side wall by a first outlet and being spaced from the second side wall by a second outlet;
a reversible fan in the cavity disposed between the baffle housing and the rear wall, the fan having a first operating mode for directing a first flow of air when the fan is operated in a clockwise direction and a second operating mode for directing a second flow of air when the fan is operated in a counterclockwise direction; and
the baffle housing including an upper baffle and a lower baffle disposed between the baffle housing and the rear wall, the first outlet bounded at least partially by the upper baffle, lower baffle, baffle housing, rear wall, and first side wall, the second outlet bounded at least partially by the upper baffle, lower baffle, baffle housing, rear wall, and second side wall, the upper baffle and the lower baffle being configured to direct the first flow of air, along the rear wall to exit the first outlet prior to intersecting the first side wall, to a first region of the cavity and to direct the second flow of air, along the rear wall to exit the second outlet prior to intersecting the second side wall, to a second region of the cavity.
