The NGM8655UC is a gas cooktop with an electronic ignition module, which means two different families of trouble can show up on one machine. Some are mechanical, such as burner parts that are dirty or out of place. Others are electrical, where the module that makes the spark is not doing its job.
Owners usually notice it as a burner that clicks and never catches, a flame that looks uneven, or a burner that goes out on its own. Cast-iron grates and burner caps get grimy over time, and a dirty cap alone can change flame quality, so routine cleaning matters more than people expect.
When we arrive we separate the two possibilities. First we look at the caps, the burner heads and their seating, then we watch the igniters while we try each burner. An E9000-type electrical problem points toward the ignition module, and we confirm that before suggesting any part.
A few seconds of ticking while it catches is normal. Ticking that keeps going without a flame usually means a dirty or misplaced cap, moisture, or a weak spark. Turn the knob off if no flame appears.
This model is not like the induction cooktops, which display codes. The one electrical family to know is E9000-type, tied to the ignition module. Most gas complaints are visible in how the flame behaves.
Whenever spills build up, and always before they bake on. Let everything cool, lift the grates and caps, wash and dry them fully, then set the caps back flat so the flame spreads evenly.
