Abstract: An electronic door opening system for an appliance is provided. The door opening system includes a resilient member having a pin that moves in a linear direction to urge an appliance door open. The door opening system further includes a toothed gear member configured to engage with the resilient member. The gear member may be driven by a motor to move the resilient member to urge the door from a closed position to an open position. Accordingly, upon receipt of a door opening command received from a user interface, the motor drives the gear to engage with the resilient member and open the door. The door opening mechanism includes components that are free from contact with other systems of the appliance. For example, in a microwave oven, the door opening system components may be free from contact with a door latch and an interlock switch system.
