Gas cooktop with griddle assembly including temperature probe for monitoring failure modes

A method for operating a gas cooktop, the gas cooktop comprising a primary gas burner, an auxiliary gas burner, a fuel supply system, and a griddle assembly comprising a griddle and a temperature probe positioned proximate the auxiliary gas burner, the method comprising:

• initiating operation of the fuel supply system in an auto griddle mode where a flow of fuel is supplied to operate the primary gas burner and the auxiliary gas burner at a target heat level;
• obtaining a griddle temperature of the griddle using the temperature probe;
• identifying a heating failure based at least in part on the griddle temperature, wherein identifying the heating failure comprises determining that the griddle temperature changes at a rate that is below a predetermined heating rate when the auto griddle mode is operated and identifying the heating failure as the failure of a bridge line valve to open;
• and
• implementing a responsive action in response to identifying the heating failure.

A gas cooktop defining a vertical direction, a lateral direction, and a transverse direction, the gas cooktop comprising:

• a primary gas burner and an auxiliary gas burner positioned adjacent to the primary gas burner;
• a griddle assembly comprising a griddle positioned over the primary gas burner and the auxiliary gas burner and a temperature probe positioned proximate the auxiliary gas burner;
• a manifold for supplying a flow of fuel;
• a primary supply line providing fluid communication between the manifold and the primary gas burner;
• an auxiliary supply line providing fluid communication between the manifold and the auxiliary gas burner;
• a bridge line providing fluid communication between the primary supply line and the auxiliary supply line;
• a supplemental line providing fluid communication between the manifold and the bridge line;
• a bridge line valve operably coupled to the bridge line for regulating the flow of fuel through the bridge line;
• a supplemental line valve operably coupled to the supplemental line for regulating the flow of fuel through the supplemental line;
• and
• a controller in operative communication with the temperature probe, the controller being configured to:
• initiate an operation of the bridge line valve and the supplemental line valve in an auto griddle mode where the flow of fuel is supplied to operate the primary gas burner and the auxiliary gas burner at a target heat level;
• obtain a griddle temperature of the griddle using the temperature probe;
• determine that the griddle temperature changes at a rate that is below a predetermined heating rate when the auto griddle mode is initiated;
• identify a heating failure corresponding to a failure of the bridge line valve to open;
• and
• implement a responsive action in response to identifying the heating failure.
