Gas burner clicks and sparks but will not light or lights only with a match.

Safety first: Turn off the burner and allow components to cool before handling. Do not use sharp metal objects that can damage burner ports.

• Check gas supply: Ensure the main gas valve is fully open and that other gas appliances in the home work normally.
• Clean burner: Remove the burner cap and head. Soak in warm soapy water and use a soft brush or wooden toothpick to clear blocked ports.
• Dry thoroughly: Dry all parts completely before reassembly to prevent ignition problems.
• Reassemble correctly: Place the burner head and cap back in their exact positions. Misalignment can prevent proper gas flow.
• Test ignition: Turn the knob to ignite and observe. If the burner still fails to light, have a gas technician check pressure and the gas valve.
