How to Replace a Cooktop Burner Head
To replace a cooktop burner head, let the cooktop cool, remove the grate and burner cap, lift off or unscrew the old burner head, clean the mounting area and gas ports gently, install the matching new burner head in the same position, then reassemble and test for an even flame and normal ignition.
A damaged or badly corroded burner head can cause weak flame, uneven heating, delayed ignition, or no ignition at that burner. This is usually a straightforward replacement, but work carefully around gas parts and stop if anything does not line up cleanly.
Before you start: Match the replacement part to your exact cooktop before ordering.
Safety first
- Work only on a fully cool cooktop.
- Handle burner parts gently so you do not damage the igniter or misalign gas openings.
- Do not force stuck screws or parts if they may break the burner base.
- Stop and get help if you smell gas or if the new burner head does not fit cleanly.

Step-by-step fix
Step 1: Cool the cooktop and set up the work area
- Make sure all burner controls are off and the cooktop is fully cool.
- Open a window or turn on kitchen ventilation if available.
- Remove any cookware from the cooktop.
- Set a towel nearby to hold the grate, burner cap, and any screws so small parts do not get lost.
If it works: The cooktop is cool, clear, and ready to work on.
If it doesn’t: Wait longer if any burner parts still feel warm.
Stop if:
- You smell gas before starting.
- A control knob feels loose or does not turn normally.
- The burner area is cracked or visibly damaged beyond the burner head.
Step 2: Remove the grate and burner cap
- Lift off the grate over the burner you are repairing.
- Remove the burner cap and set it aside in the order it came off.
- Look at how the burner head sits on the base so you can match the new part's position later.
- Use a flashlight if needed to note tabs, notches, or screw locations.
If it works: You can clearly see the burner head and how it is mounted.
If it doesn’t: If the cap or grate is stuck from grease, clean around it with warm soapy water and try again gently.
Stop if:
- The burner cap or surrounding surface is cracked.
- You have to pry hard enough to risk bending or breaking nearby parts.
Step 3: Take off the old burner head
- Lift the burner head straight up if it is a drop-in style.
- If screws hold it in place, remove them with the correct screwdriver and keep them together.
- If the burner head is stuck, wiggle it gently rather than forcing it.
- Compare the old burner head to the new one before installing anything.
If it works: The old burner head is removed and the new part appears to match its size and mounting pattern.
If it doesn’t: Clean away visible buildup around the edges and try lifting it again gently.
Stop if:
- A screw is stripped and will not turn.
- The new burner head does not match the old one closely.
- You uncover damaged wiring, a broken igniter, or a damaged gas tube.
Step 4: Clean the burner base and surrounding area
- Wipe the burner base with a damp cloth and mild dish soap.
- Use a soft brush to remove grease or food debris from grooves and around the igniter.
- Do not enlarge or poke burner openings with a drill bit, nail, or other hard metal tool.
- Dry the area fully before installing the new burner head.
If it works: The burner base is clean, dry, and free of debris that could affect alignment.
If it doesn’t: Repeat with a little more warm soapy water and a soft brush until the mounting area is clear.
Stop if:
- The igniter is loose, cracked, or out of position.
- You see heavy rust, severe corrosion, or damage on the burner base itself.
Step 5: Install the new burner head
- Set the new burner head onto the burner base in the same orientation as the old one.
- Align tabs, notches, and screw holes carefully so the part sits flat.
- Reinstall any screws snugly if your burner uses them, but do not overtighten.
- Place the burner cap back on top and make sure it sits level.
- Reinstall the grate.
If it works: The new burner head sits flat, the cap is level, and the grate is stable.
If it doesn’t: Lift the part back off and realign it until it drops into place correctly.
Stop if:
- The burner head rocks, tilts, or will not sit flush.
- Screw holes do not line up without force.
- The cap will not sit level after the new head is installed.
Step 6: Test the burner and check the flame
- Turn the burner on and watch for normal ignition.
- Let the flame run briefly and look for an even ring of flame around the burner.
- Turn the burner from low to high to confirm the flame responds normally.
- Turn the burner off and make sure the flame goes out completely.
If it works: The burner lights promptly and burns evenly without unusual flare-ups or dead spots.
If it doesn’t: Turn the burner off, let it cool, then recheck the burner head and cap alignment and clean away any remaining debris.
Stop if:
- You smell gas during testing.
- The burner clicks repeatedly but does not light.
- The flame is very uneven, lifts off the burner, or burns in the wrong place.

FAQ
How do I know the burner head needs replacement?
Replace it if it is cracked, badly corroded, warped, or if cleaning and proper reassembly do not fix uneven flame or ignition problems at that burner.
Can I clean the old burner head instead of replacing it?
Yes, if it is only dirty. Remove loose debris, wash with mild soap, dry it fully, and reinstall it correctly. Replace it if it is damaged or no longer sits properly.
Do I need to shut off the gas supply for this job?
For a simple burner head replacement on a cool cooktop, homeowners usually remove only the top burner parts. If you smell gas, need to disturb gas tubing, or are unsure what you are seeing, stop and get qualified help.
Why won't the new burner light evenly after installation?
The most common causes are a misaligned burner head, a burner cap that is not seated level, leftover debris in the burner area, or another failed part such as the igniter.
What if the burner head screws are rusted or stripped?
Do not force them until they break. Try the correct screwdriver and gentle pressure. If the screws will not come out cleanly, it is safer to stop than to damage the burner base.
