Step-by-step fix
Step 1: Confirm the igniter is the likely problem
- Make sure the burner cap and burner head are seated correctly and not blocked by grease or food debris.
- Turn the burner knob to light and watch for spark at that burner while comparing it to a working burner.
- Listen for steady clicking. A bad surface burner igniter often gives no spark, a weak spark, or sparks in the wrong spot while the other burners work normally.
- If the burner lights with a match but does not spark on its own, that points more strongly to the igniter or its immediate connection at that burner.
If it works: You have a single burner with a spark problem that matches a failed surface burner igniter.
If it doesn’t: If all burners have spark problems, check power to the range and look into the spark module or switch system instead of replacing just one igniter.
Stop if:- You smell gas that does not clear quickly after turning the burner off.
- The burner base is badly rusted, cracked, or loose enough that it cannot hold parts in position safely.
Step 2: Shut off power and open the burner area
- Unplug the range or switch off power at the breaker.
- Make sure all burner knobs are off and the cooktop is cool.
- Remove the grate, burner cap, and burner head from the problem burner.
- Take out any screws holding the burner head or cooktop section in place. If screws are stuck from corrosion, apply steady pressure and avoid stripping them.
- Lift the cooktop or access panel enough to reach the igniter and its wire connection.
If it works: The range is de-energized and you can see the old igniter and its wiring.
If it doesn’t: If the cooktop will not lift after visible fasteners are removed, look for hidden screws under caps or trim before forcing it.
Stop if:- You find damaged gas tubing, a loose burner valve, or heavy corrosion that makes the burner assembly unstable.
- A screw breaks off in a way that prevents safe reassembly of the burner.
Step 3: Remove the old igniter
- Take a clear photo of the igniter position and wire routing before disconnecting anything.
- Disconnect the igniter wire connector by pulling on the connector, not the wire itself.
- Remove the mounting screw or clip that holds the igniter to the burner base.
- Lift the igniter out carefully and compare it to the new part for matching shape, length, and connector style.
If it works: The old igniter is out and the replacement appears to match the original.
If it doesn’t: If the new part does not match closely, pause and verify fit before installing it.
Stop if:- The wire insulation is burned, brittle, or split back into the harness where a simple igniter swap will not solve the problem.
- The burner base is cracked or warped where the igniter mounts.
Step 4: Install the new igniter
- Set the new igniter in the same position and angle as the original so the spark will land at the burner correctly.
- Reinstall the mounting screw or clip snugly without overtightening and cracking the ceramic body.
- Reconnect the wire connector fully so it fits securely and does not sit loose.
- Route the wire the same way as before, keeping it away from hot surfaces, sharp edges, and moving hinges if the cooktop lifts.
If it works: The new igniter is mounted securely and wired like the original.
If it doesn’t: If the connector feels loose, inspect for bent terminals or the wrong connector style before reassembling the burner.
Stop if:- The new igniter cannot be mounted firmly in the original location.
- The wire cannot be routed safely away from heat and sharp metal.
Step 5: Reassemble the burner parts
- Lower the cooktop or reinstall the access panel carefully so no wires get pinched.
- Reinstall any screws you removed from the cooktop or burner assembly.
- Set the burner head back in place, making sure it sits flat and aligns with the gas ports.
- Reinstall the burner cap and grate in their proper positions.
If it works: The burner is fully reassembled and everything sits flat and aligned.
If it doesn’t: If the burner head or cap rocks or sits crooked, remove it and reseat it before testing.
Stop if:- Any part will not sit flat because of hidden interference, bent metal, or a trapped wire.
Step 6: Restore power and test the repair in real use
- Plug the range back in or turn the breaker on.
- Turn the repaired burner to light and watch for a strong, regular spark at the correct spot.
- Let the burner ignite and run for a minute on low and medium settings to make sure the flame stays steady.
- Turn the burner off, then relight it several times to confirm the fix holds during normal use.
If it works: The burner sparks reliably, lights promptly, and stays lit through repeated tests.
If it doesn’t: If there is still no spark or the burner still lights poorly, the problem may be in the spark wire, spark module, burner switch, or burner alignment rather than the igniter alone.
Stop if:- You hear clicking with no visible spark and also smell unburned gas.
- The flame is lifting, uneven, or burning in the wrong place after reassembly.

FAQ
How do I know the surface burner igniter is bad and not just dirty?
First clean and reseat the burner cap and head. If one burner still has no spark, a weak spark, or a spark in the wrong place while the other burners work normally, the igniter at that burner is a likely cause.
Can I replace just one burner igniter?
Yes. If the problem is limited to one surface burner, you can usually replace only that igniter instead of changing the whole ignition system.
Why does the burner click but not light after I replace the igniter?
The burner cap or head may be misaligned, the igniter may be mounted at the wrong angle, or the issue may be in the spark wire or spark module instead of the igniter itself.
Do I need to shut off the gas supply for this repair?
Usually you only need the burner knobs off and the range unplugged because you are working on the spark side, not opening gas tubing. If you find damaged gas parts or smell gas that lingers, stop and address that before continuing.
What if the mounting screw is rusted or stripped?
Do not force it until the burner base is damaged. Try the correct bit with firm pressure first. If the screw breaks or the burner base cannot hold the igniter securely afterward, the repair may need additional parts beyond the igniter.
