Gas cooktop burner ignites but flame is weak, uneven, or yellow instead of blue.

Safety first: Turn off all burners and allow them to cool before cleaning. If you suspect gas supply issues, contact your gas provider.

Steps to check:

• Clean burner: Remove burner caps and heads. Clean ports with a soft brush and warm soapy water. Use a wooden toothpick to clear stubborn clogs; avoid enlarging ports.
• Dry thoroughly: Ensure all parts are completely dry before reassembly.
• Check cap placement: Reinstall burner caps correctly; misalignment can cause yellow or uneven flames.
• Gas type: Confirm the range is set up for your gas type (natural gas vs LP). Incorrect orifices can cause improper flame color.
• Air shutter: Some burners have adjustable air shutters near the orifice. Adjust slightly to achieve a stable blue flame.

Warning: Do not attempt to drill or modify gas orifices. Use only manufacturer-specified parts.
