A motor is operatively coupled to the rotisserie arm for rotating the rotisserie arm and a food product. The oven also includes a control interface having a rotisserie cooking mode input and a control system for controlling the rotisserie motor and the heating element. In addition to other functions, the control system automatically causes the rotisserie motor to cycle on and off to allow for intermittent rotation of the food product supported on the rotisserie arm when the oven door is opened. ## Claims ### Claim 1 An oven for performing a rotisserie cooking operation comprising: an oven cavity; a door moveable between open and closed positions in order to selectively access the oven cavity; a heating element for heating the oven cavity; a rotisserie arm adapted to support a food product positioned within the oven cavity; a motor drivingly connected to rotate the rotisserie arm; a control interface having a user selectable input for a rotisserie cooking mode; and a control system for controlling said motor and said heating element wherein, upon selecting a rotisserie cooking mode through the user selectable input, the control system activates the motor for non-continuous rotation of the rotisserie arm in the oven cavity while operating the heating element to heat the oven cavity with the door in the closed position and, upon shifting the door to the open position, automatically cycles the motor on and off to cause intermittent rotation of the rotisserie arm while the door is open, and wherein the control system is configured to activate the heating element while the motor is stopped during a portion of a cooking phase with the door in the closed position. ### Claim 2 (depends on 1) The oven according to claim 1, wherein the control system cycles the motor on and off to provide for an intermittent 360 degree rotation of a food product supported on the rotisserie arm. ### Claim 3 (depends on 2) The oven according to claim 2, wherein the control system causes the intermittent 360 degree rotation to occur in 20-30 seconds. ### Claim 4 (depends on 1) The oven according to claim 1, wherein the control system regulates rotation of the rotisserie arm based on a preset timing sequence. ### Claim 5 (depends on 1) The oven according to claim 1, further comprising: a temperature sensor for sensing a temperature within the oven cavity, wherein the control system regulates rotation of the rotisserie arm based on the sensed temperature when the door is in the closed position. ### Claim 6 (depends on 1) The oven according to claim 1, wherein the cooking phase is established when the door is shifted to the closed position and the control system alters operation of the rotisserie arm supporting the food product, from when the door is in the open position, during the cooking phase. ### Claim 7 (depends on 1) The oven according to claim 1, further comprising: a convection system exposed to the oven cavity, wherein the control system shuts off both the heating element and the convection system when the door is opened, while the motor is cycled. ### Claim 8 (depends on 7) The oven according to claim 7, wherein the control system causes the motor to be automatically pulsed to rotate the rotisserie arm when the door is opened. ### Claim 9 (depends on 8) The oven according to claim 8, wherein the control system causes the rotisserie arm to be rotated through 90° with each pulse. ### Claim 10 (depends on 1) The oven according to claim 1, wherein the control system regulates a rotational speed of the motor based on user inputs. ### Claim 11 An oven for performing a rotisserie cooking operation comprising: an oven cavity; a door moveable between open and closed positions in order to selectively access the oven cavity; a heating element for heating the oven cavity; a rotisserie arm adapted to support a food product positioned within the oven cavity; a motor drivingly connected to rotate the rotisserie arm; a control interface having a user selectable input for a rotisserie cooking mode; and a control system for controlling said motor and said heating element wherein, upon selecting a rotisserie cooking mode through the user selectable input, the control system controls the motor to pulse, cycle or completely stop the rotisserie arm in the oven cavity while operating the heating element to heat the oven cavity with the door in the closed position and, in response to the door being shifted to the open position, the control system automatically cycles the motor on and off to cause intermittent rotation of the rotisserie arm while de-activating the heating element with the door in the open position, and wherein the control system is configured to activate the heating element while the motor is stopped during a portion of a cooking phase with the door in the closed position. ### Claim 12 (depends on 11) The oven according to claim 11, wherein the control system cycles the motor on and off to provide for an intermittent 360 degree rotation of a food product supported on the rotisserie arm. ### Claim 13 (depends on 11) The oven according to claim 11, further comprising: a temperature sensor for sensing a temperature within the oven cavity, wherein the control system regulates rotation of the rotisserie arm based on the sensed temperature when the door is in the closed position. ### Claim 14 (depends on 11) The oven according to claim 11, further comprising: a convection system exposed to the oven cavity, wherein the control system shuts off both the heating element and the convection system when the door is opened, while the motor is cycled. ### Claim 15 (depends on 14) The oven according to claim 14, wherein the control system causes the motor to be automatically pulsed to rotate the rotisserie arm when the door is opened. ### Claim 16 (depends on 11) The oven according to claim 11, wherein the control system regulates a rotational speed of the motor based on user inputs. ### Claim 17 An oven for performing a rotisserie cooking operation comprising: an oven cavity; a door moveable between open and closed positions in order to selectively access the oven cavity; a heating element for heating the oven cavity; a rotisserie arm adapted to support a food product positioned within the oven cavity; a motor drivingly connected to rotate the rotisserie arm; a control interface having a user selectable input for a rotisserie cooking mode; and a control system for controlling said motor and said heating element wherein, upon selecting a rotisserie cooking mode through the user selectable input, the control system is configured to: a) activate the motor to rotate the rotisserie arm in the oven cavity while operating the heating element to heat the oven cavity to establish a cooking phase with the door in the closed position; b) automatically cycle the motor on and off to cause intermittent rotation of the rotisserie arm while the heating element is deactivated with the door in the open position; and c) activate the heating element while the motor is stopped during a portion of the cooking phase with the door in the closed position.
