An oven comprising: an oven cavity;at least one heat source for supplying energy to said cavity;at least one fan assembly for circulating air in said cavity, said fan assembly comprising a fan motor, a shaft extending from said motor, and a fan coupled to said shaft; andan oven controller operationally coupled to said fan motor and said at least one heat source, said oven controller configured to:energize said fan motor during a cook cycle;de-energize said fan motor during the cook cycle;re-energize said fan motor during the cook cycle;accept data regarding a number of racks; andcontrol energization of said at least one heat source based upon the accepted data.11. An oven in accordance with claim 10, wherein said oven controller is further configured to energize said fan motor during a cook cycle for a pre-determined first time period.12. An oven in accordance with claim 11, wherein said oven controller is further configured to de-energize said fan motor during the cook cycle for a pre-determined second time period different from the first time period.13. An oven in accordance with claim 12, wherein said oven controller is further configured to re-energize said fan motor during the cook cycle for a pre-determined third time period different from the first and second time periods.14. An oven in accordance with claim 10 wherein said at least one heat source comprises a bake element, a broiler element, and a convection heating element, and wherein to accept data regarding a number of racks, said oven controller is further configured to:accept an indication of a number of racks including an indication of a single rack and an indication of multiple racks;energize said convection heating element when the accepted indication is an indication of multiple racks; andenergize at least one of said broiler element and said bake element when the accepted indication is an indication of a single rack.15. A method for controlling at least one heat source of an oven, said method comprising: receiving data regarding a number of racks;energizing a convection heating element when the received data is an indication of multiple racks; andenergizing a broiler element and a bake element when the received data is an indication of a single rack.16. A method in accordance with claim 15 wherein said receiving data comprises receiving at least one of an indication of a single rack and an indication of multiple racks.17. A method in accordance with claim 15 further comprising:energizing a fan during a cook cycle;de-energizing a fan during the cook cycle; andre-energizing a fan during the cook cycle.
