A method of operating a baking oven, the baking oven including a heating means (18, 20) arranged to underlie baking trays whereby a substantial proportion of heat provided by the heating means (18, 20) is provided to the baking trays, the method including: heating the heating means (18, 20) according to a bake program indicative of products loaded into the oven; and characterised in that the method further includes: determining an oven temperature at the start of a fixed baking time and in regular time intervals thereafter; determining the oven temperature at the end of a first predetermined portion of the fixed baking time and deactivating the heating means in response to the oven temperature reaching a trip temperature; and deactivating the heating means at the end of a second predetermined portion of the fixed baking time if the heating means is not deactivated at the end of the first predetermined portion of the fixed baking time, wherein the first predetermined portion of the fixed baking time is shorter than the second predetermined portion of the fixed baking time in case the heating means have not been switched off before the end of a second predetermined portion of the fixed baking time; whereupon the products are baked after deactivation of the heating means by residual heat within the oven for the remainder of the fixed baking time. heating the heating means (18, 20) according to a bake program indicative of products loaded into the oven; and characterised in that the method further includes: determining an oven temperature at the start of a fixed baking time and in regular time intervals thereafter; determining the oven temperature at the end of a first predetermined portion of the fixed baking time and deactivating the heating means in response to the oven temperature reaching a trip temperature; and deactivating the heating means at the end of a second predetermined portion of the fixed baking time if the heating means is not deactivated at the end of the first predetermined portion of the fixed baking time, wherein the first predetermined portion of the fixed baking time is shorter than the second predetermined portion of the fixed baking time in case the heating means have not been switched off before the end of a second predetermined portion of the fixed baking time; whereupon the products are baked after deactivation of the heating means by residual heat within the oven for the remainder of the fixed baking time. determining an oven temperature at the start of a fixed baking time and in regular time intervals thereafter; determining the oven temperature at the end of a first predetermined portion of the fixed baking time and deactivating the heating means in response to the oven temperature reaching a trip temperature; and deactivating the heating means at the end of a second predetermined portion of the fixed baking time if the heating means is not deactivated at the end of the first predetermined portion of the fixed baking time, wherein the first predetermined portion of the fixed baking time is shorter than the second predetermined portion of the fixed baking time in case the heating means have not been switched off before the end of a second predetermined portion of the fixed baking time; whereupon the products are baked after deactivation of the heating means by residual heat within the oven for the remainder of the fixed baking time.
