How to Replace a Gas Oven Igniter

 

Range oven igniter PD_0022_664_8054129

This DIY repair guide shows how to replace the oven gas igniter in a gas wall oven or gas range. The igniter heats until it's white-hot and then ignites the gas from the oven burner so the oven can heat. Because the igniter is wired in series with the safety gas valve, the gas valve won't open unless it detects that the igniter is hot enough to ignite the gas. Replace the gas igniter with a manufacturer-approved replacement part if it doesn't heat at all or if it doesn't get hot enough to open the safety gas valve.

Tools Required

  • 1/4" nut driver
  • Work gloves

Before you begin

Wear safety gloves to protect your hands. The oven interior should be cool to the touch.

Don't touch the new igniter carbide electrode. Oil from your fingers damages the igniter carbide electrode and can cause premature failure.

Instructions

 Warning: Undertaking repairs to appliances can be hazardous. Use the proper tools and safety equipment noted in the guide and follow all instructions. Do not proceed until you are confident that you understand all of the steps and are capable of completing the repair. Some repairs should only be performed by a qualified technician.

How to replace a gas oven igniter

Step 1: Shut off the electricity and gas

At the breaker panel or fuse box, shut off power to the oven. Turn the gas shut-off valve to the off position. 

 Tip: You can unplug a freestanding range at the wall instead.

Shut off the gas.

Step 2: Remove the bottom panel

Remove the oven racks.

Remove the screws at the back of the bottom oven panel. Lift the back of the panel slightly and push back to release the bottom oven panel from the retaining lip. Push down on a front corner of the bottom panel so it tips enough that you can grasp the sides of the panel. Work the bottom oven panel up and out of the oven.

 Tip: If you can't complete this repair because the door gets in your way, remove the door, following instructions in your owner's manual. You might need help lifting the door off the oven. Set the door on a pad.

Remove the bottom panel.

Step 3: Remove the screws that hold the bracket

Note how the carbide electrode on the igniter overlaps the holes in the burner. Use a 1/4" nut driver to remove the 2 hex-head screws from the bracket that holds the igniter on the burner.

Remove the mounting screws from the bracket that holds the igniter.

Step 4: Disconnect the wire harness

Detach the igniter plug from the wire harness by releasing the locking tabs on the connector. Pull the igniter out of the oven and set it aside for disposal. 

 Tip: You may need to pull a wall oven or drop-in oven from the cabinet to reach the plug for the bake igniter from behind the oven. Have a helper assist you when pulling the appliance out of the cabinet.

Release the locking tabs and unplug the wire harness.

Step 5: Connect the new igniter

Being careful not to touch the carbide electrode with your fingers, plug the igniter into the wire harness. 

 Tip: If the plug on the new igniter doesn’t fit the original wire harness connector, use a wire cutter to snip off the plug and the wire harness connector. Strip the 1/2" of insulation from the wires and make the connection with ceramic wire nuts (don't substitute plastic wire nuts, which don't withstand high heat).

Step 6: Attach the igniter to its bracket

Position the new igniter so its holes line up with those on the mounting bracket. Insert the mounting screws and tighten firmly. Push the wires down, out of the way of the burner.

 Tip: Make sure the igniter is positioned so the carbide electrode overlaps the holes in the burner.

Step 7: Reinstall the bottom panel

Work the bottom oven panel into place.

Slide the oven racks into the oven. 

Step 8: Turn on the gas and electricity

Open the gas supply shut-off valve for the oven. At the breaker panel, switch on the circuit breaker for the oven.
