Abstract: A rotatable two-piece basket assembly is behind upper and lower doors in a blower driven recirculating hot air oven. An electric heater directly adjacent a catalytic converter directly above the cooking chamber, removes contaminants. The lower basket is removed through the lower door opening, while the upper door stays closed to conserve heat. A homing control homes the basket assembly whenever the door is opened or a cooking cycle is completed, for removal of the lower basket. A filter at the blower inlet is removable through the lower doorway when the lower basket is out, for cleaning or replacement. The blower wheel is removable through the lower doorway when the filter assembly has been removed. The upper basket is removable through the combined doorway by a push-and-turn motion applied to a bayonnet connection to the basket drive shaft. Other components are then removable through the front opening.
