| description | A method for operating a consumer appliance, as provided herein, may include detecting a preliminary first conversion value from a first sensor input pin electrically connected to an analog-to-digital converter (ADC) and detecting a preliminary second conversion value from a second sensor input pin electrically connected to the ADC in electrical parallel with the first sensor input pin. The method may further include determining a preliminary variation between the preliminary first and second conversion values is less than or equal to a predetermined preliminary threshold. The method may still further include activating a pull-up resistor in electrical communication with the first sensor input pin, identifying a fault state in response based on a conversion value variation following activating the pull-up resistor, and directing the appliance based on the determined fault state. |
