How to Fix Oven Igniter: Guide for Homeowners

If you’re wondering how to fix an oven igniter, you’re not alone. A faulty igniter is one of the most common reasons a gas oven stops heating properly—and it can be incredibly frustrating when you’re trying to cook dinner and the oven just won’t cooperate.

In this guide, I’ll walk you through everything you need to know: how oven igniters work, what signs to look for when they go bad, why they fail, and step-by-step instructions on how to fix or replace them safely. Whether you’re dealing with a gas or electric oven, this article is packed with practical tips from real-world experience to help you get your oven working again.

How Do Oven Igniters Work: The Basics You Need to Know

To fix an igniter, it helps to first understand how it works. In gas ovens, the igniter’s job is to light the gas burner so your oven can produce heat.

There are two main types:

• Glow-bar igniters: These are the most common in home ovens. When you turn on the oven, electricity flows to the igniter. It heats up and starts glowing. Once it reaches the right temperature, it signals the gas valve to open, and the gas ignites.
• Spark igniters: Found in some gas stoves and ovens, these work like a spark plug, creating a quick spark to ignite the gas.

Electric ovens don’t usually use igniters. Instead, they rely on electric heating elements to generate heat directly.

If you hear clicking but no flame or notice your oven is sparking and then shutting off, it could be a sign that your gas igniter is not clicking or functioning properly.

Signs Your Oven Igniter Is Bad

Before replacing anything, let’s talk about symptoms that point to a bad igniter:

• Oven won’t heat up: The igniter might be glowing but not hot enough to open the gas valve.
• Clicking or sparking but no flame: Common with spark igniters, this usually means the igniter is trying but failing.
• Igniter glows but burner doesn’t light: A partially functioning igniter can still glow but not trigger the gas valve.
• Igniter not glowing at all: This means it’s likely burned out or not receiving power.

When my oven stopped heating last winter, the first thing I noticed was the long preheat time. Eventually, it stopped heating altogether. That was the moment I knew something was wrong with the igniter.

If you’re experiencing any of these issues, chances are you’re dealing with an oven igniter not working.

Why Do Oven Igniters Fail?

Like any hardworking appliance part, oven igniters wear down over time. Here are the main reasons they fail:

• Wear and tear: Most igniters last between 3 to 5 years with regular use. They heat up every time you use your oven, which puts a lot of stress on the element.
• Electrical issues: Loose wires, faulty control boards, or power surges can damage the igniter.
• Grease or food debris: Grease buildup can coat the igniter, affecting its performance or causing it to short.
• Overheating: Poor ventilation or running the oven at high temps frequently can reduce the igniter’s lifespan.

If your oven is a few years old and you’ve never replaced the igniter, it might just be its time. Yes, oven igniters do wear out eventually.

How to Fix an Oven Igniter (Gas and Electric Ovens)

Safety First – Before You Begin

Before you start taking your oven apart, safety is the top priority:

• Unplug the oven or shut off the breaker to cut off electricity.
• Turn off the gas supply if you’re working on a gas oven.
• Wear gloves and keep the area well-ventilated.

Don’t skip this step—it can save you from electric shocks or gas leaks.

Step-by-Step Instructions

Here’s how to fix or replace a faulty oven igniter:

• Access the igniter:
  • Remove the oven racks.
  • Take off the bottom panel of the oven to expose the burner and igniter.
• Inspect the igniter:
  • Look for visible cracks or discoloration.
  • Use a multimeter to test for continuity. No reading means the igniter is dead.
• Remove the faulty igniter:
  • Unscrew it from its mounting bracket.
  • Carefully disconnect the wires.
• Install the new igniter:
  • Use the exact same model for your oven. (Model numbers matter!)
  • Connect the wires securely.
  • Mount the new igniter in place.
• Test your oven:
  • Reconnect the power.
  • Turn on the oven and watch for the igniter to glow and the burner to light.

Tips for Success

• Use the correct replacement part—check your oven’s make and model.
• Don’t touch the igniter tip with bare hands; oils from your skin can damage it.
• If your oven has an error display, check the codes before and after the repair.

Replacing an igniter might sound technical, but it’s one of the easier DIY repairs—especially compared to full oven replacements.

Can You Clean an Oven Igniter?

Yes, but only in certain situations. Cleaning can sometimes restore function—especially if grease or food has built up on the igniter.

When Cleaning is Okay

• If the igniter still glows but struggles to light the burner
• If there’s visible dirt or gunk

How to Clean It Safely

• Turn off power and gas before cleaning.
• Use a soft brush (like a toothbrush) to remove loose debris.
• Lightly dab with isopropyl alcohol on a cotton swab to remove grease.
• Avoid water, steel wool, or anything abrasive.

In my own kitchen, I once cleaned a visibly dirty igniter and got a few more months out of it before it finally failed. It’s a good temporary fix—but don’t expect miracles.

When Should You Replace Your Oven Igniter?

So, how do you know it’s time to move on from cleaning and just buy a new part?

Signs It’s Time to Replace:

• Igniter doesn’t glow at all
• Multimeter shows no continuity
• You’ve cleaned it and it still won’t light
• Preheat times are getting longer and longer

Typical Lifespan

• 3 to 5 years, depending on how often you use your oven

Cost Breakdown

• DIY replacement: $30–$60 for the part
• Professional service: $100–$250 total

If you’re comfortable using a screwdriver and a multimeter, this is definitely a job you can do yourself.

Common Mistakes to Avoid When Fixing an Oven Igniter

Even a simple repair can go wrong if you’re not careful. Here are some common mistakes:

• Skipping the power and gas shutoff—serious safety hazard
• Buying the wrong igniter—model mismatch can damage your oven
• Improper wire connections—can lead to shorts or no ignition
• Touching the igniter tip—finger oils can shorten lifespan
• Ignoring the manual—each oven has its quirks, and instructions matter

Take your time and double-check every step. It’s worth the extra few minutes to avoid a bigger headache later.

Frequently Asked Questions (FAQ)

Q1: Why is my oven igniter not working?

Most likely, the igniter has worn out or lost electrical continuity. Test it with a multimeter to confirm.

Q2: Can you fix an oven igniter yourself?

Yes, if you’re comfortable with basic tools and safety steps. Always shut off power and gas before starting.

Q3: How do I know if my igniter is bad or the gas valve is faulty?

If the igniter glows but there’s no flame, it could be either. But a weak or no-glow igniter usually means it’s the culprit.

Q4: Is it safe to use an oven with a bad igniter?

No. A faulty igniter can prevent proper ignition, leading to gas buildup and safety risks.

Q5: Can cleaning the igniter fix it?

Sometimes. If the issue is grease or debris, a gentle cleaning can help. But not always.

Q6: Why is my gas igniter not clicking anymore?

For spark igniters, it may be a bad switch or power supply. For glow-bar igniters, they don’t click—they glow.

Q7: What does it mean if my oven sparks and stops working?

Likely a spark igniter fault or a short circuit. Turn off the oven and inspect immediately.

Q8: How long do oven igniters usually last?

Typically between 3–5 years, depending on usage and maintenance.
