How to Replace an Oven Igniter: A Complete DIY Guide

There’s nothing quite like the sinking feeling of a dinner plan gone wrong. You’ve prepped the perfect casserole, the family is hungry, and you preheat the oven… only to come back 15 minutes later to a cold, dark box. If you have a gas oven, the culprit is often a small, surprisingly simple part. Learning How To Replace An Oven Igniter might sound like a job for a pro, but it’s one of the most common and achievable DIY appliance repairs out there. Here at Oven Hi, we believe your oven is your creative partner, and we want you to feel empowered to keep that partnership going strong. So, let’s roll up our sleeves, save you a service call, and get that beautiful flame back in your oven.

First Things First: Is Your Oven Igniter the Culprit?

Before you start ordering parts, let’s play detective. A faulty igniter has a few classic tell-tale signs. Does any of this sound familiar?

The oven won’t heat up at all. This is the most obvious sign. The control panel might work, you might set the temperature, but nothing happens inside.
You smell gas but see no flame. When you turn on the oven, the gas valve opens, but if the igniter isn’t hot enough to combust the gas, it will simply accumulate. If you smell a strong gas odor, turn off the oven and the gas supply immediately, and air out your kitchen before proceeding.
The igniter glows, but the oven never lights. This is a tricky one. The igniter might still be glowing orange, but it may not be reaching the critical temperature (usually over 1800°F or 980°C) needed to open the safety valve and ignite the gas. A weak glow is a dead giveaway.
It takes a very long time for the oven to ignite. You might hear a “whoosh” as the gas finally ignites after a long delay. This indicates the igniter is weakening and on its last legs.

If you’re nodding along to one or more of these points, congratulations! You’ve likely found your problem, and the solution is a straightforward replacement.

Safety First: The Golden Rule of DIY Repair

We can’t stress this enough: safety is your number one priority. Working with gas and electricity requires your full attention. Before you touch a single screw, follow these essential steps.

Disconnect the Power: Unplug the oven from the wall outlet. Don’t just turn it off at the control panel. If you can’t reach the plug, go to your home’s circuit breaker and switch off the breaker dedicated to the oven.
Shut Off the Gas: Find the gas shut-off valve for your oven. It’s usually located behind the appliance. Turn the valve handle so it’s perpendicular to the pipe, which cuts off the gas flow.

Expert Tip: Sarah Jenkins, a certified appliance technician with over a decade of experience, reminds us, “Always double-check that the power and gas are off. A simple multimeter can confirm there’s no electricity, and a quick sniff test for gas after turning the valve provides peace of mind. Taking an extra 60 seconds on safety can prevent a major accident.”

Gathering Your Tools and Parts

You don’t need a professional’s toolkit for this job. Most of what you need is probably already in your home.

The Right Replacement Igniter: This is the most important part. You’ll need your oven’s model number (usually found on a sticker inside the oven door or on the frame) to order the exact replacement part. Don’t try to use a “universal” igniter unless it’s specifically listed as compatible with your model.
Nut Driver or Socket Wrench: A 1/4-inch or 5/16-inch nut driver is most common for removing the screws holding the igniter in place.
Screwdriver: A Phillips head screwdriver is often needed to remove the oven’s bottom panel.
Pliers: Needle-nose pliers can be helpful for disconnecting the wire harness.
Work Gloves: To protect your hands from sharp edges inside the oven.
Old Towel or Mat: To kneel on and to place screws so they don’t get lost.

Step-by-Step: Your Guide on How to Replace an Oven Igniter

Ready? You’ve got your tools, your new part, and you’ve completed your safety checks. Now for the main event. We’ll be focusing on the most common type, a flat-style “glow bar” igniter for the bake element at the bottom of the oven.

Step 1: Access the Igniter

First, you need a clear workspace.

Open the oven door and remove all the oven racks.
Look for a metal panel at the very bottom of the oven compartment. It’s usually held in place by two or more screws at the back.
Use your screwdriver to remove these screws and lift the panel out. Set it aside.
You should now see the gas burner tube (a long metal pipe with holes in it) and, attached to it, the igniter. It’s a small ceramic or metal part with wires coming out of it.

Step 2: Remove the Old Igniter

Now it’s time to take out the faulty part.

The igniter is typically held onto the burner assembly by one or two screws. Using your nut driver, carefully remove them.
Gently handle the old igniter. It can be brittle. Follow its wires to the back of the oven where they connect to a plastic wire harness.
Unplug the wire harness. This can sometimes be a bit stiff. You may need to press a small locking tab to release it. A little wiggle with your needle-nose pliers can help.
Once disconnected, you can fully remove the old igniter and its wiring from the oven.

Step 3: Install the New Igniter

You’re halfway there! Installing the new part is just the reverse of the removal process, with one very important detail.

Crucial Warning: The element on your new igniter is extremely fragile and sensitive to oils from your skin. Do not touch the dark gray or black part of the new igniter with your bare hands. Handle it by its ceramic base or metal bracket only. Skin oils can create a hot spot on the element, causing it to burn out prematurely.

Carefully position the new igniter.
Secure it to the burner assembly using the screws you removed earlier. Don’t overtighten them—just snug is good enough.
Route the wires to the back and plug the new wire harness into the oven’s connector. You should hear or feel a “click” as it locks into place.
Tuck the wires away so they aren’t touching the burner tube or the oven floor.

Step 4: Reassemble and Test

It’s time for the moment of truth.

Place the bottom oven panel back in position and secure it with its screws.
Put the oven racks back inside.
Turn the gas supply back on by turning the valve handle parallel to the pipe.
Plug the oven back into the wall outlet or flip the circuit breaker back on.
Set your oven to bake at around 350°F (175°C).
Watch and wait! Within 30 to 90 seconds, you should see the new igniter glow a bright orange-yellow, followed by the satisfying whoosh of the main burner igniting.

You did it! You’ve just successfully completed a major appliance repair. That feeling of accomplishment is almost as good as the smell of fresh-baked cookies, which you should definitely make to celebrate.

What if It Still Doesn’t Work?

In the vast majority of cases, the steps above will solve your problem. However, if the oven still won’t light, the issue might be a bit more complex, such as a faulty gas safety valve or a control board issue. At this point, it’s wise to acknowledge the limits of DIY and call a qualified appliance repair technician. You’ve already done the most common repair, so you can be confident you didn’t pay for a service call you didn’t need.

Frequently Asked Questions (FAQ)

How long does an oven igniter last?

On average, an oven igniter has a lifespan of 3 to 5 years, depending on usage. It’s a consumable part, much like a lightbulb, and is designed to be replaced over the life of the oven.

How much does it cost to replace an oven igniter?

Doing it yourself is incredibly cost-effective. A new igniter part typically costs between $20 and $60. In contrast, a professional service call, including parts and labor, can easily range from $150 to $300, so learning how to replace an oven igniter offers significant savings.

Can I replace the igniter myself?

Absolutely. As long as you are comfortable with basic tools and meticulously follow safety procedures for shutting off gas and electricity, this is considered one of the easier DIY appliance repairs.

Why is my new oven igniter not working?

The most common reason is accidentally touching the element with bare hands, causing it to fail immediately. Other possibilities include a loose wire connection or, less commonly, receiving a defective part. Double-check your connections first.

What’s the difference between a bake and a broil igniter?

Many gas ovens have two separate igniters: one for the bake element at the bottom and one for the broil element at the top. They often look similar but may not be interchangeable. Always make sure you are ordering and replacing the correct igniter for the function that has failed.
