Abstract

A method for controlling a pyrolysis cleaning process in an oven includes the steps: a) heating an oven cavity of the oven by switching on a heat source; b) measuring, using an oxygen sensor, an oxygen concentration in the oven cavity or in an exhaust-air conduit configured to discharge fumes from the oven cavity; c) comparing, in an evaluation circuitry of an electrical control unit, the measured oxygen concentration to a predefined limit value stored in a memory; d) operating, if the measured oxygen concentration drops below the limit value, the oven for a predefined first time interval with the heat source switched off, a duration of the first time interval being stored in the memory; and e) repeating steps b) through d) after the first time interval has ended; or f) repeating steps a) through d) if the measured oxygen concentration is equal to or greater than the limit value.
