At least two blowers are controlled with baffles to create circulating zones of airflow which circulate in a substantially horizontal plane within a convection oven cavity. This airflow minimizes the potential for airflow paths to be broken up or blocked by the configuration of objects placed in the oven. The substantially horizontal airflow reduces the non-uniformity of air temperature distribution within the oven cavity. The blowers may be controlled to rotate either simultaneously or alternately, depending on the selected mode of operation. The blowers and associated heating elements are controlled to operate in various cooking modes by the controller in response to a mode selector input.
