Abstract
A microwave oven comprises a cooking cavity and a RF generation module configured to deliver microwave energy into the cooking cavity. A controller is operatively associated with the RF generation module. The controller receives and processes a signal indicative of current state of an associated energy supplying utility for determining whether to operate the microwave oven in one of a normal operating mode and an energy savings mode in response to the received signal. The controller is configured to at least temporarily block the signal when the RF generation module is activated if a frequency of the signal is at least partially degraded by a frequency of the RF generation module.
