How to Replace an Upper Oven Igniter
If the upper oven will not heat or takes a long time to light, replacing the upper oven igniter is a common fix.
This repair is usually straightforward, but you need to work carefully around sharp metal panels and a gas ignition system. Start by confirming the igniter is the likely cause, then swap it with a matching replacement and test the oven through a full heat-up.
Before you start: Match the igniter style, connector, and appliance compatibility before ordering.
Safety first
- Turn off power before opening panels or disconnecting the igniter.
- Let the oven cool fully before reaching into the burner area.
- Wear gloves because oven panels and brackets can have sharp edges.
- If you smell persistent gas, stop and do not continue testing the oven.

Step-by-step fix
Step 1: Confirm the upper oven igniter is the likely problem
- Set the upper oven to bake and watch through the bottom opening or listen near the burner area.
- Look for a weak glow, no glow, or a long delay before the burner lights.
- Notice whether the oven temperature stays low even though the control appears to be calling for heat.
- Cancel the cycle and let the oven cool before starting the repair.
If it works: The symptoms point to a failed or weak upper oven igniter rather than a simple control setting issue.
If it doesn’t: If the upper oven heats normally, this is not the right repair. If nothing in the oven responds at all, check power supply, controls, or a broader ignition problem instead.
Stop if:
- You smell gas that does not clear quickly after canceling the cycle.
- The burner area shows heavy scorching, melted wiring, or damaged tubing.
- You are not confident working around a gas appliance.
Step 2: Shut off power and get safe access to the igniter
- Turn off power to the oven at the breaker or unplug it if the plug is accessible.
- Open the upper oven door and remove the racks so you have room to work.
- Lift out the oven bottom panel if your model uses one, then remove the flame spreader or burner cover if present.
- Use a flashlight to locate the igniter mounted near the burner tube.
If it works: You can clearly see and reach the upper oven igniter and its mounting hardware.
If it doesn’t: If the panel will not lift out, look again for hidden screws at the rear or sides before forcing anything.
Stop if:
- A panel is warped in place from heat damage.
- You uncover broken burner parts, loose insulation, or damaged wiring.
Step 3: Remove the old upper oven igniter
- Take a photo of the igniter position and wire routing before disconnecting anything.
- Remove the screws holding the igniter to the burner or bracket.
- Follow the igniter wires to the connector. Disconnect the plug if accessible, or carefully reach the connection through the rear access area if needed.
- Pull the old igniter out gently without banging the tip against metal parts.
If it works: The old upper oven igniter is out and you know how the new one needs to sit and route.
If it doesn’t: If the connector is out of reach from inside the oven, pull the oven forward carefully and remove the rear access panel to reach the wiring connection.
Stop if:
- The wire insulation is brittle, burned, or crumbling.
- The connector is fused together or the harness side is heat-damaged.
Step 4: Install the new upper oven igniter
- Compare the new igniter to the old one for mounting style, connector type, and wire length before installing it.
- Position the new igniter in the same direction and location as the original.
- Secure the mounting screws snugly without overtightening them.
- Reconnect the wiring and route the wires away from the burner flame path and hot surfaces.
- Avoid touching the igniter element more than necessary while handling it.
If it works: The new upper oven igniter is mounted firmly and the wiring is connected and safely routed.
If it doesn’t: If the new part does not line up or the connector does not match, stop and verify you have the correct replacement before reassembling.
Stop if:
- The replacement part clearly does not fit the burner bracket or harness.
- The burner tube or mounting area is cracked or badly rusted.
Step 5: Reassemble the oven interior
- Reinstall the flame spreader or burner cover in its original position.
- Set the oven bottom panel back in place and fasten any screws you removed.
- Slide the racks back into the upper oven.
- Restore power to the oven.
If it works: The oven is back together and ready for a live heating test.
If it doesn’t: If a panel rocks, rattles, or will not sit flat, remove it and check that no wires or brackets are trapped underneath.
Stop if:
- A panel cannot be secured because the mounting holes or supports are damaged.
Step 6: Test the repair through a full heat-up
- Set the upper oven to bake at a normal cooking temperature.
- Watch for the new igniter to glow and for the burner to light within a reasonable time.
- Let the oven continue heating long enough to confirm it climbs toward the set temperature and cycles normally.
- Listen and look for smooth ignition without repeated failed starts.
If it works: The upper oven lights reliably, heats up normally, and holds temperature better than before.
If it doesn’t: If the igniter glows but the burner still does not light, or the oven still will not heat properly, the problem may be with the gas valve, control, wiring, or another ignition component.
Stop if:
- You smell persistent gas during the test.
- Ignition is delayed with a loud whoosh or flare.
- The breaker trips or you see sparking or smoke.

FAQ
What are the signs of a bad upper oven igniter?
Common signs are no heat, very slow preheating, a glowing igniter that never lights the burner, or an oven that struggles to hold temperature.
Can an oven igniter fail even if it still glows?
Yes. A weak igniter can glow but still fail to draw enough current to open the gas valve properly, so the burner may not light.
Do I need to shut off the gas to replace the upper oven igniter?
For a basic igniter swap, the main safety step is turning off electrical power. If you smell gas or need to disturb gas tubing, stop and get qualified help.
How do I avoid ordering the wrong upper oven igniter?
Match the mounting style, connector type, wire length, and appliance compatibility. Comparing the old part to the new one before installation helps catch a mismatch early.
What if the new igniter does not fix the upper oven?
If the new igniter is installed correctly and the oven still will not heat, the issue may be in the gas valve, wiring, control, or another ignition-related part.
