<p>The method involves monitoring operating temperature of magnetrons (22-26). A predetermined operating temperature or a predetermined operating temperature curve indicating impending failure of one of the magnetrons is detected. A signal e.g. optical and/or acoustic information signal, is outputted to a user via a controller (20), where the signal is predefined for the impending failure of the magnetron. Power distribution between the magnetrons is changed on a control side by the signal such that the failure magnetron is controlled. An independent claim is also included for a microwave oven comprising magnetrons.</p> |
