Kitchens that cook for a crowd tend to choose the NGM3650UC. This 36 inch 300 Series gas cooktop has five sealed burners and 41,400 BTU, and its extra width is used mostly to separate the burners so that five full-size pans can sit on it together.
That width also means larger, heavier grates. Dropping one on a foot, or onto the ceramic-topped glass, is a real risk when cleaning, so lift them slowly and set them down on a towel. Over time the rubber feet can perish, and then the grates slide and scratch the surface.
Two things stand out when we service one. The simmer burner may run too high for delicate sauces if its valve needs adjusting, and the spark module may fire every igniter when a single flame is lost. We check both, along with the feet, before looking at anything more involved.
Often yes. The simmer burner's valve has an adjustment, and when it is set too high the lowest flame is still too strong. A technician makes that change, and we confirm it with a pot of water.
The spark module is designed to fire when a flame is lost, so more than one igniter may tick together. It is normal behavior and stops once the flame is back or the knob is off.
Check that every rubber foot is present and clean. If they are cracked, flattened or hard, replacing them stops the scratching. Do not use a grate that rocks over a lit burner.
