How to Replace a Gas Stove Igniter: Step-by-Step (With Safety)

To replace a gas stove igniter, shut off the gas supply valve and unplug the range, lift the burner cap and grate to expose the ceramic spark electrode (cooktop) or remove the oven floor to reach the glow-bar igniter (oven), unclip the wire harness, swap in the OEM-matched part, then run a soap-water leak test before relighting.

That’s the short version. The long version is what keeps you from a delayed-ignition pop, a small gas leak, or a $300 service call you didn’t need. This guide walks through a gas stove igniter replacement for both cooktop spark electrodes and oven glow-bar igniters, with the safety steps the popular video tutorials skim past.

Key Takeaways

• Knowing how to replace gas stove igniter parts the right way comes down to four things: identify the part, diagnose before buying, kill the gas and power, and leak-test before relighting. A cooktop spark electrode replacement runs about 20 minutes; an oven glow-bar igniter takes under an hour. Part cost: $9 to $60.
• Diagnose before buying. A clamp multimeter that reads 2.8–3.0 amps on the bake-circuit wire confirms a healthy oven glow-bar; below 2.5 amps, replace.
• Before any disassembly, check your model number against the CPSC recall notice (~175,000 units affected).
• Per NFPA 54 §9.6.4, the appliance shutoff valve must be in the same room and within 6 feet. Confirm it works before you start.
• Use OEM part numbers (GE WB13K21, WB2X9154, WB18K10098; Frigidaire 316489403, 5304509706; Whirlpool 4342528, 98005652). Manufacturer-approved replacement parts are recommended for compatibility and safety.
• Always run a 50/50 soap-water leak test on every joint you touched before relighting. Bubbles = stop, call a pro.
• Reseat the rear leg into the anti-tip bracket. Modern freestanding ranges have included anti-tip brackets since the early 1990s.

Should You Replace a Gas Stove Igniter Yourself?

For most US homeowners, yes. A cooktop spark electrode swap is a 20-minute job, and an oven glow-bar igniter is usually under an hour once the oven is cool. The part runs $9 to $60 at Home Depot or RepairClinic, and which avoids the typical $150 to $300 service call. DIY replacement can significantly reduce labor costs compared to a full service visit.

You should not DIY this if any of these apply. You smell gas right now. Your supply line is corrugated stainless steel (CSST) and needs disconnection. You converted the range to propane and the orifices were swapped. The wiring connector you uncover looks burnt. 

The job sits in the same DIY tier as replacing a dishwasher drain hose or a dryer heating element. Solidly intermediate. If you’ve ever tested an outlet with a multimeter, you have the skill set.

Step Zero: Is Your Range Under Recall?

Before you remove a single screw, write down your model and serial number from the metal data plate (usually under the cooktop or behind the storage drawer) and check it against the active CPSC recall list. In March 2026, Electrolux Group recalled roughly 175,000 Frigidaire gas ranges over a burn hazard linked to the front-control knobs. “CPSC Frigidaire gas range recall (March 2026)” notice for the affected model list and the free remedy.

If your unit is on that list, do not disassemble it. The manufacturer remedy may include a free repair or refund, and self-repair can void the recall fix.

What Type of Gas Stove Igniter Do You Have?

In many DIY repair cases, spark electrodes are replaced unnecessarily when the actual problem is a failing spark module, leading to wasted time and incorrect fixes.

• Spark electrode (cooktop). A small white ceramic body with a metal tip and a single spade-wire connector, mounted next to each burner. One burner clicks but won’t light is the classic sign.
• Spark switch (cooktop). A switch behind each control knob. If your cooktop won’t stop clicking, even with all the knobs off, the spark switch under one knob is shorted. Sears PartsDirect’s spark-switch guide covers this exact failure.
• Spark module (cooktop control unit). The black box, usually mounted under the cooktop or behind the back panel, that fires every electrode. If no burner sparks at all, it’s the spark module, not an electrode.
• Hot-surface igniter, also called the glow-bar (oven). A round or flat ceramic igniter inside the oven cavity. When it works, it glows orange before the gas valve opens. When it fails, the oven fan runs but never heats.

Cooktop sparking on one burner points to an electrode issue. Sparking on every burner with no ignition usually indicates a failing module. Continuous clicking suggests a faulty switch. An oven that runs but stays cold typically points to a glow-bar igniter problem.

How Do You Know the Igniter Is Actually Bad?

The two-minute visual and audible test handles most cooktop diagnoses. Turn the burner knob to “light.” If you hear clicking but see no spark, the electrode is cracked or wet. If only one burner clicks while you turn another’s knob, the spark switch is shorted. If you hear nothing on any burner, the spark module is dead.

For the oven glow-bar igniter, iFixit’s GE bake-igniter guide documents the verifiable spec. A healthy igniter pulls 2.8 to 3.0 amps on the bake circuit. Below 2.5 amps, it has lost enough resistance to glow but not enough to open the safety gas valve, and it needs replacement.

To run that test, clamp a Fluke 323 (or any clamp meter that reads AC amps) around the white bake-circuit wire under the oven floor, set the oven to bake at 350°F, and read the meter once the igniter glows. Don’t remove the wire. The clamp meter reads the field around it. 

If the reading is healthy and the oven still won’t heat, the gas safety valve or control board is the suspect, not the igniter. Buy the meter test before you buy the part.

What Tools and Parts Do You Need?

• 1/4″ nut driver
• Phillips #2 screwdriver
• Needle-nose pliers
• Clamp multimeter (Fluke 323 or similar) for oven igniter diagnosis
• 50/50 dish soap and water in a spray bottle for the leak test
• Replacement igniter, OEM part for your model

Match the part number to your range. ANSI Z21.1, the voluntary standard for household gas ranges published by CSA and referenced by the “ANSI Z21.1 gas range parts standard”, requires that replacement parts be manufacturer-approved to keep the range compliant. Aftermarket “universal” igniters often fit but may pull the wrong amperage.

Common OEM part numbers:

Brand	Cooktop spark electrode	Oven glow-bar igniter
GE	WB13K21	WB2X9154, WB18K10098
Frigidaire	5304509706	316489403
Whirlpool	98005652	4342528

Cross-reference your model against the part number on RepairClinic, Home Depot, or the OEM parts portal. The part typically costs $8.85 (Seneca River Trading aftermarket electrode) to $58.96 (GE WB2X9154 from Appliance Warehouse), with a median around $26 across the five shopping listings we pulled.

How Do You Safely Shut Off Gas and Power Before Working on the Range?

This section is critical for safety. Skip a step here and you risk a delayed-ignition event the “CPSC delayed-ignition documentation” formally describes. Gas pools, then ignites all at once when the spark catches.

1. Find the appliance shutoff valve. Per the “NFPA 54 §9.6.4 accessible gas appliance shut-offs” interpretation of the 2024 National Fuel Gas Code, every gas appliance is generally expected to have an accessible shutoff valve in the same room, within 6 feet of the appliance, and accessible. For a freestanding range, that valve is usually behind the unit on the wall. Pull the range out and turn the valve handle perpendicular to the pipe. That’s “off.”
2. Unplug the range or trip the dedicated breaker. Photograph any wires before you disconnect them.
3. Confirm a working CO alarm in the kitchen. “CPSC carbon monoxide safety guidance” requires a CO detector on every level of a home with gas appliances. Press the test button before you start.
4. Note the anti-tip bracket position. The bracket has been required on every freestanding range sold since 1991, “CPSC range and oven safety”. Mark its floor location with painter’s tape so you can reseat the rear leg into it when you slide the range back.

How Do You Replace a Cooktop Spark Electrode?

1. Lift the grate and the burner cap off the burner you’re working on. Lift the burner head straight up. It’s not bolted; it just sits on the orifice holder.
2. Remove the screw or clip that secures the electrode to the orifice holder. On most GE and Frigidaire models, it is a single Phillips screw. On Whirlpool, a metal retainer clip slides off.
3. Trace the electrode’s wire back to the spark module connector. Some ranges require lifting the cooktop on a hinge: squeeze the spring clips at the front corners and tilt the cooktop up. Photograph the wire route before you unplug.
4. Unplug the spade connector at the spark module end and remove the old electrode.
5. Route the new electrode’s wire along the same path, plug it into the module, seat the electrode in the orifice holder, and replace the screw or clip.
6. Reassemble in reverse: cooktop down, burner head, cap, grate.

The new electrode tip should sit about 1/8 inch from the burner head, the same gap as the original. Too close and it will short to the burner. Too far and the spark won’t jump. If you’ve done this before, you know that gap is the part nobody tells you about.

Preventing future ignition problems

Grease buildup and liquid overflow around burner ports can interfere with ignition performance over time. Keeping the cooktop surface easier to clean and protected from heavy residue can help reduce debris accumulation around burner assemblies and spark electrodes.

How Do You Replace an Oven Glow-Bar Igniter?

1. With the oven cool, gas off, and range unplugged, remove the racks and the metal oven floor (usually two screws at the back).
2. The igniter sits at the rear, behind the burner tube. Two screws hold its mounting bracket. A ceramic wire-nut-style connector joins its leads to the oven harness.
3. Unscrew the bracket, pull the igniter forward, and twist the ceramic connector apart. Glow-bar igniters are brittle. Handle by the bracket, not the white element.
4. Install the new igniter. Match the connector orientation, twist the ceramic housing closed, and tighten the bracket screws.
5. Reinstall the oven floor and racks.

A note on touching the new igniter: oils from your skin can shorten its life. Hold it by the bracket or wear cotton gloves. RepairClinic’s WB13K21 video walkthrough shows the correct grip.

How Do You Test for Gas Leaks After Reassembly?

Reconnect the gas, leave the range pulled out, and run the soap test on every joint you touched. Mix dish soap and water 50/50 in a spray bottle. Spray the appliance shutoff valve, the flexible connector at both ends, and any union you opened. Bubbles forming = leak. Shut the gas off again and call a licensed gas technician. Do not relight.

If you see no bubbles, plug the range back in and test ignition. Cooktop electrodes should spark within one second of turning the knob to “light.” An oven glow-bar should glow orange within 60 seconds, then the gas valve opens and the burner lights with a soft whoosh, not a pop. A pop means delayed ignition, the same hazard the CPSC report describes. Shut off and recheck.

Push the range back into position, settle the rear leg into the anti-tip bracket, and verify with a hand wiggle that it doesn’t tilt forward.

When Should You Stop and Call a Pro?

There are five conditions where this stops being a DIY job:

• You smell gas at any point and the smell does not clear within minutes of shutting off the supply.
• The burner flame burns yellow or leaves soot on the cookware after replacement, a sign of incomplete combustion and a possible CO source.
• Your supply line is CSST (corrugated stainless steel tubing); it requires bonded fittings and is not a homeowner job.
• The range was converted between natural gas and propane and the orifices were swapped. A wrong-orifice install will pass a soap test but produce CO.
• Multiple igniters fail at once (every cooktop electrode plus the oven glow-bar). That points to the spark module or main control board, both of which sit at the upper edge of DIY difficulty.

A service call often ranges between $150 and $300 depending on region, labor rates, and appliance type. Compared to the potential safety risks associated with gas appliance issues, many homeowners consider this a reasonable cost.

How to Replace Gas Stove Igniter Parts Safely: Frequently Asked Questions

Can I replace a gas stove igniter myself? 
Yes, for the common cases. A single cooktop spark electrode or a single oven glow-bar igniter is a job most homeowners with basic hand tools can finish in under an hour. Stop and call a pro if you smell persistent gas, the supply line is CSST, or the range was converted between natural gas and propane.

How can you tell if a gas stove igniter is bad?
On the cooktop, listen and look. Clicking with no spark on one burner = electrode. No spark on any burner = spark module. Non-stop clicking = spark switch. For the oven, clamp a multimeter on the bake-circuit wire. A healthy glow-bar igniter pulls 2.8 to 3.0 amps. Below 2.5 amps, replace it.

How much does it cost to replace a gas stove igniter? 
The OEM part runs $9 to $60 at Home Depot, RepairClinic, or the manufacturer parts portal. Seneca River Trading lists an aftermarket spark electrode at $8.85, and a GE WB2X9154 oven igniter runs $58.96. A licensed appliance technician charges $150 to $300 for the same job, so DIY pays back on the first repair.

Do you need to turn off the gas to replace an igniter? 
Yes. The 2024 NFPA 54 / ANSI Z223.1 National Fuel Gas Code requires an accessible appliance shutoff valve in the same room, within 6 feet, for exactly this reason. Close that valve, unplug the range, and verify a working CO alarm before you start.

What is the difference between a spark electrode and a hot surface igniter? 
A spark electrode lives next to a cooktop burner and fires a high-voltage spark to ignite gas. A hot-surface igniter, also called a glow-bar, lives in the oven cavity and works by glowing orange. Its resistance drops as it heats, opening the gas safety valve. They are not interchangeable, and replacement part numbers are different even within the same range.
