Flame rectification circuit system for a gas cooktop

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

• an open loop gas burner configured to perform an open loop cooking operation and a closed loop gas burner configured to perform the open loop cooking operation or a closed loop cooking operation;
• a flame rectification circuit for detecting a flame at the closed loop gas burner;
• a spark module comprising a plurality of spark electrodes, at least one of the plurality of spark electrodes being operably coupled to each of the open loop gas burner and the closed loop gas burner;
• and
• a controller in operative communication with the flame rectification circuit and the spark module, the controller being configured to:
• determine that the closed loop gas burner is performing the closed loop cooking operation;
• determine that no flame is present at the closed loop gas burner using the flame rectification circuit;
• and
• operate the spark module to energize the plurality of spark electrodes in response to determining that no flame is present during the closed loop cooking operation.
