How to Replace a Cooktop Igniter
To replace a cooktop igniter, first confirm the burner is getting gas but not sparking or lighting reliably, then disconnect power, remove the burner parts and top access pieces, swap in the matching igniter, and test for strong, consistent ignition.
A worn, cracked, or shorted igniter can keep one burner from lighting or make it click weakly and inconsistently. This repair is usually manageable for a careful homeowner, but you do need to work safely around both electricity and gas components.
Before you start: Match the igniter style, connector, and appliance compatibility before ordering.
Safety first
- Disconnect electrical power before opening the cooktop, since the ignition system uses high voltage to create spark.
- Work only on a cool cooktop to avoid burns from grates, caps, and burner parts.
- Pull wire connectors by the terminal, not the wire, to avoid hidden wire damage.
- Stop if you smell persistent gas or find damaged gas tubing, valves, or melted wiring.

Step-by-step fix
Step 1: Confirm the igniter is the likely problem
- Try the problem burner and listen for clicking while turning the burner knob to light.
- Compare that burner to a working burner. A bad igniter often means one burner will not spark, sparks weakly, or clicks without producing a visible spark at the electrode.
- Check for obvious buildup, food residue, or moisture around the burner cap and igniter tip. Clean and dry the area first if it is dirty or wet.
- Make sure the burner cap is seated correctly. A misaligned cap can mimic an igniter problem by preventing proper lighting.
If it works: You have a burner that still will not spark or light reliably after basic cleaning and correct burner cap placement.
If it doesn’t: If the burner lights normally after cleaning, drying, or reseating the cap, you likely do not need to replace the igniter yet.
Stop if:
- You smell gas strongly and the smell does not clear quickly after turning the burner off.
- Multiple burners have the same ignition problem, which points to a broader spark module, switch, or power issue instead of one igniter.
Step 2: Shut off power and set up the work area
- Turn off power to the cooktop at the breaker or unplug it if it has an accessible plug.
- Shut off the gas supply if your setup allows easy access to the appliance shutoff valve.
- Make sure all burner knobs are off and the cooktop is completely cool.
- Lay out a towel or small container for screws and burner parts so nothing gets mixed up.
If it works: The cooktop is cool, de-energized, and safe to open.
If it doesn’t: If you cannot confidently disconnect power, pause and get help before opening the cooktop.
Stop if:
- You cannot safely shut off electrical power to the appliance.
- The shutoff valve, wiring area, or cooktop top is damaged, loose, or corroded enough to make disassembly unsafe.
Step 3: Open the cooktop and reach the igniter
- Remove the burner grates, burner caps, and any burner heads or trim pieces that block access.
- Take out the screws holding the burner base or top panel as needed to lift the cooktop top or access panel.
- Lift the top carefully and support it if needed so you do not strain wires or gas tubing.
- Locate the igniter for the problem burner and note how the wire is routed and attached before removing anything.
If it works: You can clearly see the igniter, its mounting point, and its wire connection.
If it doesn’t: If the top does not lift easily, look again for hidden screws under burner parts instead of forcing it.
Stop if:
- You find cracked gas tubing, damaged valve parts, or signs of arcing and melted wiring beyond the igniter area.
- The cooktop top or burner base is seized in place and forcing it may bend or break the appliance.
Step 4: Remove the old igniter
- Disconnect the igniter wire by pulling on the connector, not the wire itself.
- Remove the mounting screw or clip holding the igniter in place.
- Lift the old igniter out and compare it to the replacement, checking the tip shape, bracket position, and connector style.
- If there is grease or carbon buildup around the mounting area, wipe it away so the new igniter seats cleanly.
If it works: The old igniter is out and the replacement matches the original connection and mounting style.
If it doesn’t: If the replacement does not match, stop and verify compatibility before installing anything.
Stop if:
- The wire terminal is burned, brittle, or broken back into the harness.
- The mounting area is cracked or too damaged to hold the new igniter securely.
Step 5: Install the new cooktop igniter
- Set the new igniter into the same position as the old one so the spark tip sits in the same relation to the burner.
- Reinstall the mounting screw or clip snugly without overtightening and cracking the ceramic body.
- Reconnect the wire firmly to the igniter terminal.
- Route the wire the same way it was originally so it stays clear of hot surfaces, sharp edges, and moving parts.
If it works: The new igniter is mounted securely, connected firmly, and routed safely.
If it doesn’t: If the wire will not seat firmly or the igniter does not align with the burner correctly, recheck the part and mounting position before reassembling.
Stop if:
- The ceramic body cracks during installation.
- The connector is loose enough that it will not stay attached or the wire insulation is damaged.
Step 6: Reassemble the cooktop
- Lower the cooktop top or reinstall the access panel carefully without pinching the igniter wire.
- Reinstall all screws, burner bases, burner heads, caps, and grates in the same order they came off.
- Double-check that the burner cap on the repaired burner is centered and seated flat.
- Restore power and, if you shut it off, restore the gas supply.
If it works: The cooktop is fully reassembled and ready for testing.
If it doesn’t: If parts do not sit flat or screws do not line up, reopen the top and check for a trapped wire or mispositioned burner part.
Stop if:
- You smell gas after restoring the supply.
- A burner part will not seat correctly because of hidden damage or a warped mounting surface.
Step 7: Test ignition and confirm the repair holds
- Turn the repaired burner to light and watch for a strong, visible spark and prompt ignition.
- Let the burner run for a minute, then turn it off and relight it several times to confirm consistent operation.
- Test the neighboring burners briefly to make sure nothing was disturbed during reassembly.
- Listen for normal clicking behavior and make sure the repaired burner lights without repeated attempts.
If it works: The repaired burner sparks consistently and lights normally through several test cycles.
If it doesn’t: If the burner still does not spark or light reliably, the problem may be in the spark module, switch, wiring, burner alignment, or gas flow rather than the igniter alone.
Stop if:
- You see arcing to the wrong metal surface, repeated misfiring, or exposed damaged wiring during testing.
- The burner releases gas but still will not ignite after rechecking burner cap alignment and the new igniter connection.

FAQ
How do I know the cooktop igniter is bad?
A bad igniter often affects one burner more than the others. You may hear clicking with no visible spark, see a weak or inconsistent spark, or have a burner that only lights occasionally after the cap and burner area have been cleaned and dried.
Can I replace a cooktop igniter myself?
Many homeowners can, as long as they can safely disconnect power, remove the cooktop parts without forcing them, and reinstall the new igniter in the same position. Stop if you run into damaged wiring, gas parts, or a strong gas smell.
Do I need to shut off gas to replace the igniter?
If your cooktop has an accessible shutoff valve, it is a smart extra safety step. The most important requirement is disconnecting electrical power before opening the cooktop, since the igniter circuit creates spark.
Why does the burner still not light after I replaced the igniter?
The root cause may be elsewhere. Common possibilities include a bad spark module, a faulty ignition switch, damaged wiring, a misaligned burner cap, or a gas flow problem at that burner.
Can I clean the igniter instead of replacing it?
Sometimes, yes. If the igniter tip is just dirty or damp, careful cleaning and drying may restore normal spark. If the ceramic is cracked, the tip is damaged, or the burner still misfires after cleaning, replacement is the better fix.
