Ice bin level sensor

An appliance, comprising:

• a housing configured to receive ice from an ice maker, the housing comprising at least a first wall;
• and
• an ice level sensor comprising a control circuit and at least a first electrode array,
• the first electrode array comprising a first sense electrode, a second sense electrode and a first shield electrode, such that the second sense electrode and the first shield electrode are each oriented parallel to the first sense electrode, with the first shield electrode positioned between the first and second sense electrodes, and the first electrode array positioned one of on an outside surface of the first wall of the housing and on an inside surface of the first wall of the housing,
• the ice level sensor configured to detect ice in the housing based on a measured capacitance of at least one of the first and second sense electrodes, and
• the control circuit configured to compensate for frost build-up detected by the first shield electrode.
