Can I replace just one gas stove burner igniter?

Often, yes, when the parts list identifies a separate igniter or electrode for that burner and only one burner is affected. The worked example replaces one complete large-front assembly while leaving the other three in place. Use the appliance model and the original part's mounting and connector details to select the replacement.

Do I have to disconnect the gas line to replace a burner igniter?

No. The worked repair keeps the gas line connected, closes the supply valve during access, and reopens it for testing. If the valve or supply is not safely accessible, stop and use a qualified professional.

What if the new igniter still does not spark?

Do not keep cycling the burner. Recheck the connector latch, wire route, electrode position, and part match, then stop. A new igniter does not rule out a switch, harness, control, or grounding problem, so further electrical diagnosis should be handled by a qualified technician.

Can I replace a gas oven igniter using these steps?

No. An oven glow-bar igniter is a different component with different access, wiring, and testing considerations. Identify the exact oven igniter from the oven's model information and follow its manufacturer instructions or have it serviced.

How to Replace a Gas Stove Igniter: A Step-by-Step DIY Walkthrough

Confirm the burner igniter is the failed part

This walkthrough covers a replaceable burner igniter, the electrode beside the burner cap that makes the visible spark. It does not cover the round glow-bar igniter inside a gas oven. A no-spark complaint can also come from moisture, a loose connection, a damaged harness, a faulty switch, or a control module, so replacement should follow a basic check of the burner assembly and accessible wiring.

In the worked case, the large front burner on a freestanding four-burner gas range makes no spark while the other three work. That pattern makes one burner-specific part more plausible than a shared power problem, but it does not prove the igniter is defective. The range is moved only far enough to reach the rear service area, with the floor protected and the appliance kept stable.

If the model uses electronic ignition, a flame can often still be lit manually according to the manufacturer's instructions. Follow that procedure only; do not improvise a lighting method. Stop and contact a gas-service professional if you smell gas, hear continuous hissing, find damaged wiring, or cannot confirm the failed component.

Identify the exact replacement igniter

The worked range has model number RGB525BH printed on a label inside the storage drawer. The service sheet lists burner igniter assembly WH14X26772 for all four positions. A removable electrode marked 5304525190 is also available, but it is not the complete assembly used in this repair. The original part number is useful for cross-checking, not a universal substitute list.

The replacement is checked against the old assembly before installation. Both have a flat mounting tab with one screw hole, a ceramic spark electrode, a metal spark tip, and a two-wire connector. The harness length and connector orientation also match. A visually similar igniter with a different tab, terminal, or cable route may not install correctly.

Attribute	Worked-example match	Why it matters
Appliance model	RGB525BH	Confirms the parts-list context
Original assembly	WH14X26772	Matches the listed complete assembly
Electrode-only number	5304525190	Different part scope; not selected
Mounting	One flat screw tab	Must line up with the cooktop bracket
Electrical lead	Two-wire connector	Must match the range harness
Burner position	Large front burner	Parts can differ by burner size

Prepare the range and reach the igniter

Unplug the range and shut off the gas-supply valve. Do not disconnect the gas line for this repair. If the valve cannot be reached or operated safely, stop and use a qualified professional. Work on a dry floor with the burner controls in the off position, and keep children and pets away from the appliance.

Remove the grate, burner cap, and burner head from the large front position. The worked range uses a removable grate and cap; the burner head lifts away after the cap is removed. Parts are placed in order on a towel. No cleaner is added, because residue or moisture around the electrode can interfere with the new part.

From the rear, remove the two screws holding the service cover and lift the cover away. A flashlight shows the igniter lead passing through an open channel in the cooktop support. The wires are followed from the connector to the electrode before anything is detached, and their original route is noted for reassembly.

Remove the old igniter and install the matching assembly

The connector is reached from behind the cooktop. Its locking tab is pressed while the connector is pulled straight apart; the wires are not tugged. One Phillips screw secures the igniter's flat mounting tab. The screw, tab, and electrode are removed as one assembly, with the burner base supported so it does not drop into the range.

The new WH14X26772 assembly is placed in the same orientation as the old one. Its tab sits flat on the bracket, the ceramic body remains clear of the burner, and the spark tip points toward the original gap. The mounting screw is tightened until the tab is secure, without forcing the ceramic or twisting the lead. The connector is pushed together until its latch engages.

Before replacing the service cover, the wire is checked for slack through its full route and for contact with the burner or sharp metal. The burner head, cap, and grate are reinstalled in their original positions. On this model, the burner head has locating features that help align it; forcing it is unnecessary. The cover is then secured with its two screws.

Confirm the replacement matches the old igniter before removing anything.
Keep the burner cap, head, grate, and screws organized by position.
Press connector latches instead of pulling on wires.
Support the burner base while removing the mounting screw.
Verify the electrode and lead are clear after installation.

Test the replacement and check for gas leaks

Restore power and reopen the gas-supply valve. Stand beside the control rather than directly over the burner, and turn the large-front control to the ignite position. The replacement should produce a spark and the burner should light. Release the control when the flame is established. A brief gas odor during ignition can occur, but gas should not continue escaping or accumulate.

The worked example produces a spark and a steady flame after the new assembly is connected. The burner is observed through several ignition cycles. A weak spark, delayed ignition, flame lift-off, or uneven flame is not treated as a successful repair; stop using that burner and reassess the installation or call a qualified technician.

Check every disturbed gas connection with a commercial gas-leak detector or the method specified by the range manufacturer. Do not use a flame. If bubbles form, a leak detector alarms, or gas is smelled, close the supply valve, leave the area if conditions feel unsafe, and contact the gas utility or a licensed gas professional. Have the appliance inspected before using it again.

Return the range to service and record the repair

When the burner remains stable and no leak is detected, slide the range back carefully without pinching the power cord or gas supply. Leave enough clearance for the manufacturer's installation requirements, and confirm the appliance is level and stable. Do not use the burner again if the flame changes, the spark disappears, or a gas odor returns.

Record the range model, the installed assembly number, and the replacement date in a maintenance file. Keep the old igniter until the repair has completed several normal cooking cycles. This makes it easier to compare parts if the new assembly does not fit or if a later inspection is needed.

This repair addresses one replaceable burner igniter. It does not establish why a different burner stopped sparking or how much a professional replacement would cost. For repeated failures, multiple dead burners, damaged wiring, or uncertain ignition timing, use a qualified appliance or gas-service technician.
