Gas surface burner will not ignite; no clicking or spark is heard.

Safety first: Turn off power and gas before lifting the cooktop or accessing ignition components. Do not attempt repair if you smell gas.

Steps to check and correct:

• Swap components: Move the burner cap and head from a working burner to the non-working one. If it still does not spark, the issue is electrical.
• Inspect igniter: Check the ceramic igniter for cracks or heavy buildup. Clean gently and ensure the gap to the burner is correct.
• Check wiring: Lift the cooktop (if design allows) and inspect the igniter wire from the spark module to the burner. Reconnect any loose wires.
• Test burner switch: The small switch on the gas valve may be open. Replace the switch if it does not close when the knob is turned.

When to call a technician: If wiring or the spark module needs replacement, or if multiple burners are affected, professional diagnosis is advised.
