Abstract
A convection cooking appliance includes an oven cavity surrounded by an air channel assembly. The appliance includes heating units and a microwave generator arranged in the air channel assembly. A blower assembly is provided to generate a recirculating flow of air through the air channel assembly and the oven cavity. A controller, responsive to operator inputs, as well as signals from both temperature and pressure sensors located in the air channel assembly, regulates the activation/deactivation state of each of the components. One of the heating units in the air channel assembly is preferably constituted by an open coil heating element which is de-activated when the pressure is sensed to be below a specified threshold.
