Step-by-step fix
Step 1: Confirm the burner head is the likely problem
- Make sure the range is cool before touching the burner parts.
- Remove the grate and burner cap from the problem burner.
- Compare that burner to a working one on the same range.
- Look for a burner head that is cracked, warped, heavily corroded, clogged, or sitting crooked on the base.
- If the burner has been lighting poorly, note whether the igniter clicks normally but the flame spreads unevenly or only lights on one side.
If it works: You have a clear reason to replace the burner head instead of guessing.
If it doesn’t: If the burner head looks normal and the igniter does not click, the cap does not fit right, or the burner still seems wet or dirty, troubleshoot those issues before replacing this part.
Stop if:- You smell a strong gas odor that does not clear quickly with the burner off.
- The burner base, gas tube area, or igniter looks damaged, loose, or burned through.
- Rust or damage is severe enough that the burner head cannot be removed without breaking surrounding parts.
Step 2: Shut off power and set up the work area
- Turn the burner control to off.
- Unplug the range or switch off power at the breaker so the igniter cannot spark while you work.
- If your range has a gas shutoff valve that is easy to reach, turn it off for extra safety during the repair.
- Set the grate, cap, and any screws aside where they will not get mixed up.
If it works: The range is safe to work on and the burner parts are organized.
If it doesn’t: If you cannot safely disconnect power or access the burner area without forcing parts, pause and get help before continuing.
Stop if:- You cannot turn off power to the appliance.
- A control knob feels stuck between settings or does not turn fully off.
Step 3: Remove the old burner head
- Lift off the burner cap if you have not already removed it.
- Check whether the burner head lifts straight off or is held by one or more screws.
- If screws are present, remove them carefully and keep them for reuse unless the new part includes replacements.
- Lift the burner head straight up to avoid bumping the igniter or scraping the gas opening.
- Compare the old burner head to the new one to make sure the size, shape, and mounting points match.
If it works: The old burner head is off and the replacement matches the original layout.
If it doesn’t: If the burner head is stuck, apply gentle pressure and clean around it first rather than prying hard against the cooktop.
Stop if:- The mounting screws are seized and start stripping.
- The igniter cracks, loosens, or shifts out of place during removal.
- The new burner head does not match the old one closely enough to seat the same way.
Step 4: Clean the burner base and alignment points
- Use a soft brush to remove loose food, grease, and corrosion from the burner base.
- Clear any visible debris around the gas opening and around the igniter, but do not bend the igniter.
- If the old burner ports were clogged, use a wooden toothpick or other nonmetal pick to clear loose debris from the surrounding area only.
- Wipe the surface dry so the new burner head can sit flat.
If it works: The burner base is clean and ready for the new part to sit level.
If it doesn’t: If buildup will not come off or the burner base itself is rusted through or misshapen, the problem may be deeper than the burner head alone.
Stop if:- You find cracks, heavy rust, or a distorted burner base under the old part.
- The igniter is damaged or no longer aligned near the burner edge.
Step 5: Install the new burner head
- Set the new burner head in place, lining up the notch, tabs, or screw holes the same way the old one sat.
- Make sure it sits flat without rocking.
- Reinstall any screws and tighten them snugly without overtightening.
- Place the burner cap back on top and make sure it sits centered and stable.
- Reinstall the grate.
If it works: The new burner head is seated correctly and the burner stack is back together.
If it doesn’t: If the cap rocks, the head sits unevenly, or the screw holes do not line up, remove the part and realign it before testing.
Stop if:- The burner head will not sit flat even though the part appears to match.
- A mounting point is broken or the cooktop surface under the burner is damaged.
Step 6: Restore power and test the burner in real use
- Turn the gas back on if you shut it off earlier.
- Restore power to the range.
- Light the repaired burner and watch for ignition within a normal few clicks.
- Check that the flame spreads around the burner head evenly and burns steady instead of lifting, sputtering, or leaving dead spots.
- Let the burner run for a minute on low and then on medium to confirm the flame stays even.
- Use the burner again during normal cooking to make sure the repair holds once the parts heat up.
If it works: The burner lights reliably and the flame stays even during actual use.
If it doesn’t: If the burner still clicks repeatedly, lights only on one side, or smells like gas when trying to light, recheck cap and burner head alignment. If alignment is correct, the issue may be with the igniter, burner base, or gas flow rather than the burner head.
Stop if:- You smell ongoing gas while the burner is on or after turning it off.
- Flames are large, uneven, yellow, or lifting off the burner head after correct installation.
- The burner will not ignite consistently even though the new head is installed properly.

FAQ
What does a bad range surface burner head look like?
Common signs are cracks, warping, heavy corrosion, clogged flame ports, or a burner head that no longer sits flat. Any of those can cause delayed ignition or uneven flame spread.
Can I clean the old burner head instead of replacing it?
Sometimes yes. If the burner head is only dirty, careful cleaning may restore normal flame. If it is warped, cracked, badly rusted, or still burns unevenly after cleaning, replacement is the better fix.
Why does the burner click but not light evenly?
That often means the igniter is sparking but the gas is not spreading correctly across the burner head. A clogged, damaged, or misaligned burner head is a common cause.
Do I need to shut off the gas to replace the burner head?
Turning off the burner control and disconnecting power are the main safety steps. If your gas shutoff valve is easy to reach, turning it off adds another layer of safety while you work.
What if the new burner head does not fit quite right?
Do not force it. Recheck the part against your exact range model and compare the mounting shape, tabs, and screw locations to the original. A burner head that does not sit flat is the wrong part or the wrong alignment.
