Abstract
A cooktop appliance includes a cooking panel comprising a heating zone, an infrared (IR) sensor array positioned below the heating zone, the IR sensor array comprising a shielded IR sensor and an IR source, and a controller operatively coupled to the shielded IR sensor and the IR source. The controller is configured to receive a first signal from the shielded IR sensor, energize the IR source to illuminate a pan in the heating zone, receive a second signal from the shielded IR sensor, identify a fault in the IR sensor array based on a comparison between the first signal and the second signal, and generate a fault signal in response to identifying the fault in the IR sensor array.
