Thermador Cooktop

[LEFT]I have a SGSCV36GW Thermador cooktop. Front left burner (XLW) has had problems for a sometime with staying lit. Burner would frequently go out after some time, igniter would start clicking. Now, it doesn’t come on at all and the igniter makes a clicking sound. I don’t smell any gas.

[COLOR=#000000]Recently, the lft rear burner does not click and not light up. However, it lights up when I turn on one of the burners on the right side.
