How to Replace a Cooktop Burner Igniter
To replace a cooktop burner igniter, shut off power and gas, remove the burner cap and top pieces needed to reach the igniter, swap in the matching new igniter, then reassemble and test for a strong spark and normal burner lighting.
This repair is usually worth trying when one burner will not spark, sparks weakly, or keeps misfiring even after the burner cap and ports have been cleaned and dried. Work carefully around gas parts and stop if you find damaged wiring, a gas smell that does not clear, or a cracked cooktop surface.
Before you start: Match the igniter style, connector, and appliance compatibility before ordering.
Safety first
- Shut off electrical power before opening the cooktop or touching ignition wiring.
- Shut off the gas supply if you will be lifting the cooktop or working near burner tubing.
- Do not force stuck screws or burner parts on a glass or ceramic surface.
- Watch for sharp metal edges under the cooktop.
- If you smell gas that does not clear quickly, stop and address that before continuing.

Step-by-step fix
Step 1: Confirm the igniter is the likely problem
- Make sure the burner cap is seated correctly and the burner head is clean, dry, and lined up the way it should be.
- Try the burner again and listen for clicking while watching for a visible spark at that burner.
- Compare it to a working burner. A bad igniter often gives no spark, a weak spark, or sparks in the wrong spot while other burners work normally.
- If the burner has been wet recently, let it dry fully before replacing parts.
If it works: You have a clear reason to suspect the cooktop burner igniter instead of a simple cleaning or moisture issue.
If it doesn’t: If cleaning, drying, and reseating the burner parts restores normal ignition, you do not need to replace the igniter.
Stop if:
- You smell gas before starting the repair or after turning the burner knob off.
- More than one burner has the same ignition problem, which can point to a switch, wiring, or spark module issue instead of one igniter.
- The cooktop surface is cracked or broken around the burner area.
Step 2: Shut off power and gas, then open the cooktop
- Turn off electrical power to the cooktop at the breaker or unplug it if it has a plug.
- Shut off the gas supply valve to the appliance if it is accessible.
- Remove the burner grate, burner cap, and any burner head pieces covering the failed igniter.
- Take photos before removing screws or disconnecting anything.
- Remove the screws or fasteners holding the burner assembly or cooktop top in place, then lift the top carefully enough to access the igniter underneath.
If it works: The cooktop is safely opened and you can reach the igniter and its wire connection.
If it doesn’t: If the top will not lift after visible screws are removed, check again for hidden fasteners under caps or trim instead of forcing it.
Stop if:
- You cannot safely shut off power or gas.
- A screw is seized badly enough that forcing it may crack the cooktop or damage the burner base.
- You find heavy rust, burned insulation, or signs of heat damage around the burner.
Step 3: Remove the old igniter
- Locate the igniter at the problem burner and trace its wire to the connector or terminal.
- Take a close photo of the wire routing and connector position.
- Disconnect the igniter wire by pulling on the connector, not the wire itself.
- Remove the mounting screw, clip, or bracket holding the igniter in place.
- Lift the old igniter out carefully so you do not bend nearby gas tubing or damage the burner base.
If it works: The old igniter is out and the mounting area is ready for the new part.
If it doesn’t: If the connector is stuck, use needle-nose pliers gently on the terminal and wiggle it free rather than pulling harder on the wire.
Stop if:
- The wire terminal is burned, loose, or crumbling.
- The burner base is cracked or too corroded to hold the new igniter securely.
- You find damaged gas tubing or a loose gas fitting near the burner.
Step 4: Install the new cooktop burner igniter
- Compare the new igniter to the old one for mounting style, length, connector type, and spark tip position.
- Set the new igniter in the same position as the original so the spark gap lines up with the burner correctly.
- Reinstall the mounting screw, clip, or bracket without overtightening.
- Reconnect the wire firmly and route it the same way as before, keeping it away from hot surfaces and sharp edges.
- Double-check that the igniter sits solidly and does not touch parts it should not touch.
If it works: The new igniter is mounted securely and wired the same way as the original.
If it doesn’t: If the new part does not match the old one closely enough to mount and connect the same way, pause and verify the replacement before reassembling.
Stop if:
- The replacement part will not mount securely or the connector does not fit.
- The wire insulation is damaged enough that it could short against metal.
- The igniter position cannot be set close to the original spark location.
Step 5: Reassemble the burner parts
- Lower the cooktop top carefully and reinstall all screws and fasteners.
- Reinstall the burner head, making sure it sits flat and aligns with its locator tabs or openings.
- Set the burner cap back in place correctly.
- Reinstall the grate and any other removed trim pieces.
- Check that nothing rocks, binds, or sits crooked around the repaired burner.
If it works: The cooktop is back together with the burner parts seated correctly.
If it doesn’t: If the burner head or cap will not sit flat, remove it and realign it before testing. Poor alignment can mimic a bad igniter.
Stop if:
- A burner screw spins without tightening because the mounting area is stripped or broken.
- The cooktop top will not sit down properly after reassembly, which can mean a trapped wire or misrouted part.
Step 6: Restore power and gas, then test the repair in real use
- Turn the gas supply back on if you shut it off, then restore electrical power.
- Turn the repaired burner to ignite and watch for a strong, regular spark at the igniter.
- Confirm the burner lights within a normal few clicks and that the flame looks even around the burner.
- Turn the burner off and on a few times to make sure the repair holds after repeated use.
- Listen for clicking to stop once the flame is established, if that matches normal operation on your cooktop.
If it works: The burner sparks normally, lights reliably, and works like the other burners.
If it doesn’t: If the burner still will not spark or still clicks abnormally after the new igniter is installed, the problem may be in the spark wire, ignition switch, burner alignment, or spark module.
Stop if:
- You smell gas and the burner does not light promptly.
- Sparking happens away from the burner or to the cooktop frame.
- The burner lights but the igniter keeps behaving abnormally compared with the other burners.

FAQ
How do I know the igniter is bad and not just dirty?
If the burner parts are clean, dry, and seated correctly but that burner still has no spark, a weak spark, or a spark in the wrong place, the igniter is a likely cause. If several burners act up at once, the problem is more likely elsewhere.
Can I replace a cooktop burner igniter myself?
Many homeowners can handle it if they are comfortable shutting off power and gas, removing burner parts, and reassembling them carefully. Stop if you find damaged wiring, cracked surfaces, or anything involving a gas leak.
Why does my cooktop igniter keep clicking after replacement?
That can happen if the burner cap is misaligned, the burner is still damp or dirty, the spark is grounding in the wrong place, or the issue is actually in the switch or spark module rather than the igniter itself.
Do I need to shut off the gas to replace the igniter?
If you are lifting the cooktop or working near burner tubing, shutting off the gas is the safer approach. It reduces risk while you have the appliance open.
What if the new igniter looks a little different from the old one?
Small cosmetic differences can be fine, but the mounting style, connector, and spark tip position need to match closely enough to install securely and spark in the right spot. If those do not match, verify the part before using it.
