A method for controlling the cooking process in a cooking chamber of an oven is provided. The chamber includes at least one heating element, at least one fan having respective intake and delivery areas, and at least one baking tray. A temperature sensor is arranged in the delivery area, measuring the temperature of the air and/or steam which comes into contact with the food at the entry to the at least one baking tray, and compares that to the cooking temperature which is set in the corresponding cooking program. The method includes: providing a second temperature sensor in the intake area of the fan; calculating temperature difference detected by the sensors; setting a predetermined difference between the temperatures; and controlling the heating element and the fan during cooking to keep the temperature difference in the cooking chamber equal to or below the predetermined value throughout the actual cooking time.

Point values for each element that exert thermal stress on a high-temperature furnace are integrated with an operation time of the high-temperature furnace as an integration period, in which the point values are obtained by converting actual values of a thermal stress of each of elements into a reference thermal stress (reference value of the thermal stress received by the high-temperature furnace per the unit time). A point value obtained by converting a limit value of the thermal stress with which the high-temperature furnace can normally operate into the reference thermal stress is set as a lifetime thermal stress, the point value integrated with the operation time of the high-temperature furnace as the integration period is set as an accumulated thermal stress, and a remaining lifetime of the high-temperature furnace equipment is predicted from the result of subtracting the accumulated thermal stress from the lifetime thermal stress.
