Gas Range Igniter Won't Click: Diagnosis and Repair

Gas range igniters fail quietly. One day you're turning the knob and hearing that satisfying rapid-fire click, and the next day—silence. The burner lights if you use a match, so you know the gas is flowing, but that click is gone. This isn't a minor annoyance. A clicking igniter saves you from the fumbling ritual of lighting your burner with external fire, and it's your first line of safety feedback that the system is working. The good news: this repair lives squarely in handyman territory. You're not replacing the entire cooktop or calling a technician. You're diagnosing which of four common failure points is the culprit, then swapping out one part. Most of the time it's the igniter module itself, which costs less than twenty dollars and takes longer to remove than to install.

1. Kill the Power First. Locate the breaker for your range in the main panel and flip it off. If your range is plugged in, unplug it from the wall outlet. Wait thirty seconds. This is not optional—you are working around live electrical components inside the range.
2. Find the Silent Burner. Turn the power back on temporarily. Turn the knob for each burner one at a time and listen carefully. You'll hear a clicking sound from the igniter under the grate—it's a rapid electric ticking, about 10 clicks per second. If one burner is silent, you've found your problem. If all burners are silent, the issue is likely the main control module or a shared ground wire. Turn the power back off again.
3. Expose the Igniter. Lift off the metal grates and set them aside. Then remove the burner caps—these are the metal crowns that sit on top of the burner. They lift straight up. Set them somewhere safe where you won't accidentally knock them over.
4. Spot the Ceramic Module. Look at the cooktop surface where the non-clicking burner is. The igniter is a small ceramic or porcelain piece, usually white or tan, sitting directly under that burner opening. It's roughly the size of a postage stamp, with a visible spark electrode (a thin metal pin sticking up). Follow the wire coming from it—it runs to a ceramic terminal block or directly into the range control assembly. This wire is what you'll disconnect.
5. Check for Water Damage. Look at the igniter closely. If it's wet, has white crusty deposits, or the electrode appears pitted or broken, you've found your problem. Moisture is the second most common reason an igniter stops clicking—it shorts out the electrical circuit. If the igniter looks clean and the electrode is intact, the module itself is likely internally failed and needs replacement.
6. Disconnect the Wire. Locate where the wire connects to the igniter. It's typically held in a ceramic terminal block that slides off, or it's screwed onto a brass connector. If it's a sliding terminal, gently wiggle it side to side while pulling straight out. If it's screwed on, use a small screwdriver to loosen the screw counterclockwise until the wire comes free. Take a photo of this connection before you disconnect it.
7. Extract the Old Module. The igniter is held in place by a single screw or a push-fit clip. If it's a screw, remove it with a screwdriver. If it's a clip, push down on the clip while pulling the igniter up gently. The igniter will slide out from under the cooktop. Some ranges have the igniter glued in place with high-temperature ceramic adhesive—if this is the case, wiggle it gently back and forth until it breaks free.
8. Clear the Debris. Before installing the new igniter, wipe out the area under the cooktop where the old igniter was sitting. Use a dry cloth or paper towel to remove any debris, corrosion, or residue. If you see heavy grease buildup, use a cloth lightly dampened with rubbing alcohol and let it dry completely before installing the new igniter.
9. Seat the New Igniter. Slide the new igniter into the mounting location under the cooktop, aligning it with the screw hole or clip. If it uses a screw, insert the screw and tighten it by hand first, then use a screwdriver to snug it down—don't overtighten, as this can crack the ceramic. If it uses a clip, push the igniter up until the clip seats fully and clicks into place.
10. Restore the Connection. Take the disconnected wire and reattach it to the new igniter using the same method it was originally connected—slide it onto the terminal or screw it on. Make sure the connection is snug and the wire is fully seated. If the connection is loose, the igniter will click intermittently or not at all.
11. Reassemble the Burner. Place the burner cap back onto the burner, making sure the center electrode aligns with the igniter electrode below. Then place the grate back on the cooktop, seating it firmly. The grate should sit flat and level.
12. Confirm the Click Returns. Turn the power back on at the breaker or plug in the range. Turn the knob for the repaired burner and listen for the clicking sound. You should hear rapid clicking immediately when you turn the knob. The igniter should spark visibly under the burner cap. If you hear clicking and see a spark, the repair is complete. If there's no click, turn off power and check the wire connection.
