Abstract
Provided is a refrigeration appliance including a storage compartment, a user interface controller, and a user interface arranged in the storage compartment. The user interface is a stacked arrangement including a sensor assembly carrier, a graphic overlay, a light guide, and a printed circuit board (PCB) with a user interface controller and a self-capacitive electrode sensor. The main controller receives a signal from the user interface with self-capacitive electrode sensor and adjusts the temperature of the storage compartment based on the signal from the self-capacitive electrode sensor. A method controlling a refrigeration appliance with a stacked user interface is also provided.
