Step-by-step fix
Step 1: Confirm the igniter is the likely problem
- Set the oven to bake and watch through the bottom vents or remove the oven bottom if needed to see the burner area.
- Listen and look for the igniter. A failed igniter may stay dark, glow weakly, or glow for a long time without the burner lighting.
- Pay attention to timing. If the oven takes much longer than normal to light or you smell gas before ignition, a weak igniter is a common cause.
- Make sure the cooktop burners still work if this is a gas range. That helps narrow the problem to the oven ignition side rather than the home gas supply.
If it works: The symptoms point to a weak or failed oven igniter.
If it doesn’t: If the igniter glows bright and the burner still will not light, or the whole range has no gas or no power, this may be a different repair.
Stop if:- You smell a strong gas odor that does not clear quickly after turning the oven off.
- You see burned wires, melted insulation, or signs of arcing around the igniter circuit.
- You are not comfortable working around a gas appliance and live electrical parts.
Step 2: Shut the range down and open the oven for access
- Turn the oven controls off and let the oven cool fully.
- Unplug the range or switch off the circuit breaker.
- If you need to pull the range out to reach a rear access panel, shut off the gas supply valve first.
- Remove the oven racks.
- Lift out the oven bottom panel and any flame spreader or burner cover above the bake burner, keeping screws organized as you go.
If it works: The range is safely shut down and the igniter is exposed or nearly exposed.
If it doesn’t: If the igniter wiring does not disconnect from inside the oven, pull the range forward carefully and check for a rear access panel.
Stop if:- The gas shutoff valve will not turn and the range must be moved to continue.
- A panel is stuck because of corrosion or hidden fasteners and forcing it may bend or damage the oven interior.
Step 3: Remove the old igniter
- Locate the igniter mounted beside the bake burner tube.
- Take a photo of the wire routing and connector position before disconnecting anything.
- Remove the igniter mounting screws while supporting the part so it does not hang by the wires.
- Disconnect the igniter plug if it has one. If it uses wire nuts or spliced leads, undo the old connection and save any high-heat connectors that are still usable.
- Pull the old igniter out carefully without scraping the fragile igniter element against metal parts.
If it works: The old igniter is out and you know how the new one needs to be routed and connected.
If it doesn’t: If a screw is seized, use steady pressure and the correct driver size. If it still will not move, apply penetrating oil only away from the igniter and burner openings, then try again after waiting.
Stop if:- The burner tube is cracked, badly rusted through, or loose at its mounting points.
- The wire insulation is brittle or damaged beyond the igniter leads.
Step 4: Install the new igniter
- Compare the new igniter to the old one for bracket shape, lead length, and connector style before mounting it.
- Handle the new igniter gently and avoid touching the carbide tip more than necessary.
- Mount the new igniter in the same position and orientation as the old one so it sits correctly by the burner.
- Reconnect the wiring. Use the plug connector if it matches. If the new igniter has bare leads, make secure high-heat connections with ceramic wire nuts and keep the splice away from direct flame.
- Route the wires back through the same path so they are clear of the burner, hot surfaces, and sharp edges.
If it works: The new igniter is mounted securely and wired safely.
If it doesn’t: If the new igniter does not match the old bracket or connector well enough to mount cleanly, pause and verify the replacement part before going further.
Stop if:- The replacement part clearly does not fit the burner or wiring setup.
- You cannot make a safe high-heat wire connection with the parts on hand.
Step 5: Reassemble the oven and restore power
- Reinstall the burner cover, flame spreader, and oven bottom panel in the same order they came out.
- Put the racks back in place.
- If you moved the range, slide it back carefully without kinking the gas line.
- Turn the gas supply back on if you shut it off.
- Plug the range back in or reset the breaker.
If it works: The oven is back together and ready for a live test.
If it doesn’t: If a panel will not sit flat, remove it and check for a misplaced screw, crossed panel edge, or wire caught underneath.
Stop if:- You smell gas after turning the supply back on.
- The range power cord, outlet, or terminal area shows heat damage.
Step 6: Test a full bake cycle and make sure the repair holds
- Set the oven to bake and watch for ignition through the vent openings or listen for the burner to light.
- The new igniter should begin heating promptly and the burner should light without a long delay.
- Let the oven run long enough to cycle at least once so you know it can relight normally after reaching temperature.
- Check that there is no repeated clicking, delayed ignition, or gas smell before lighting.
- Confirm the oven reaches and maintains a normal baking temperature in real use.
If it works: The burner lights reliably, the oven heats normally, and the repair holds through a full cycle.
If it doesn’t: If the igniter glows but the burner still does not light correctly, the problem may be with the gas valve, burner, wiring, or control circuit.
Stop if:- The burner lights with a loud whoosh, delayed ignition, or repeated gas odor.
- The breaker trips, wiring overheats, or the igniter does not behave normally during the test.

FAQ
How do I know the oven igniter is bad?
Common signs are no bake ignition, very slow ignition, weak glowing without flame, or a gas smell before the burner lights. A weak igniter can glow and still be bad.
Can I replace a range oven igniter myself?
Many homeowners can, as long as they are comfortable shutting off power, removing oven panels, and making safe high-heat wire connections if needed.
Do I need to shut off the gas to replace the igniter?
If you can access and replace the igniter from inside the oven without moving the range, the main gas supply usually does not need to be shut off. If the range must be pulled out or a rear panel opened, shut the gas off first.
Why does the new igniter have bare wires instead of a plug?
Some replacement igniters are universal-style parts. They may need to be spliced to the existing harness with high-temperature ceramic wire nuts instead of plugging directly into the old connector.
What if the igniter glows but the oven still will not light?
That can mean the igniter is weak, installed incorrectly, or the problem is elsewhere, such as the gas valve, burner, wiring, or control. A bright glow alone does not prove the igniter is good.
