Why does my gas stove keep clicking? Causes and fixes
A gas stove that keeps clicking - sparking with the knobs off or after lighting - is most often caused by moisture in the igniter system, a misaligned burner cap, or a shorted igniter switch. Because the switches are wired in parallel, one shorted switch makes every burner click. If clicking continues with all knobs off, unplug the range. Identify your model number to order the correct replacement parts.

Safety information
GAS APPLIANCE - READ BEFORE ANY WORK. If you smell gas at any point, stop immediately, do not operate switches or create sparks, ventilate, leave the area, and contact your gas utility from outside the home. Unplug the range before testing the igniter switches, electrodes, or spark module - the ignition circuit runs on household power. Do not disassemble gas-carrying components; valve, orifice, and regulator work requires a qualified technician.
Most common causes
- Moisture in the igniter system — water from cleaning or a boilover bridges the spark electrodes or switch contacts; the most common cause and one that often resolves as things dry.
- Misaligned burner cap — a cap seated crooked after cleaning changes the spark gap and keeps the module firing.
- Shorted igniter switch — the small switch behind one control knob shorts closed, and because the switches share a circuit, all burners click continuously.
- Cracked spark electrode — a damaged ceramic insulator leaks spark to ground, and the module keeps firing trying to complete ignition.
- Failing spark module — the module itself sticks in the firing state or fires erratically.
- Knob or valve not fully off — a knob resting just off its detent holds the ignition circuit closed.
Step-by-step diagnosis
- Confirm every knob is fully in its off detent - a knob resting a few degrees off keeps the circuit live. If clicking is accompanied by any gas smell or hissing, stop: turn the knobs off, do not operate other switches, ventilate, leave the area, and contact your gas utility before any further work.
- Dry the burner area thoroughly if the clicking began after cleaning or a boilover. Remove the grates, caps, and burner heads, towel-dry everything, and let the igniter electrodes and the area around them air-dry for several hours - overnight for a soaking. Moisture is the most common cause and needs no parts.
- Reseat the burner caps and heads. Each is keyed to sit one way; confirm every cap sits flat and doesn’t rock. A crooked cap changes the electrode gap and keeps the module sparking even after a successful light.
- Unplug the range (or switch off its circuit) if clicking persists with everything dry and seated. Constant sparking wears the module and is a nuisance; the range should stay unplugged except during the tests that follow.
- Isolate a shorted igniter switch. With the range unplugged, disconnect the igniter switch harness (the tech sheet shows the connector) and restore power briefly: if the clicking stops with the switches disconnected, one switch in the set is shorted. Switch kits replace the full set on most models - moisture or grease in any one switch causes this.
- Inspect each spark electrode for cracks in the ceramic insulator and burnt or rounded tips. A cracked electrode leaks its spark to the burner base and keeps the module firing; replace the damaged electrode.
- Replace the spark module last. If clicking continues with the igniter switches disconnected, the module itself is stuck firing - replace it. The module mounts under the cooktop or behind the control panel with a wiring plug and two screws on most models.
Replacement parts to consider
Common parts for constant clicking: igniter switch kit, spark electrode, spark module, burner cap, burner head. Enter your oven’s model number on reliableparts.com for the exact parts for your specific model.
Related FAQs
Why does my gas stove keep clicking after the burner is lit?
Clicking that continues after ignition means the system still sees an incomplete light: a cap sitting crooked, moisture on the electrode, or a flame-sensing gap issue on models that monitor the flame. Reseat the cap first and dry the burner area - those two cover most post-ignition clicking.
Why do all my burners click when I only turned on one?
That’s by design revealing a fault: every igniter fires from one shared spark module, so all burners always click together during ignition. Constant all-burner clicking with the knobs off means one shorted igniter switch is holding the shared circuit closed - any single wet or worn switch does it.
How long does it take a wet igniter to dry out?
A light splash usually dries in an hour or two with the caps and grates removed; a boilover or an enthusiastic deep-clean can need overnight. Speed it up with a fan across the cooktop. Avoid aiming a hair dryer at the switches behind the knobs - gentle air across the burner area is enough.
Can I keep using my stove while it clicks constantly?
The burners will usually still light and cook, but constant sparking wears the module, drains into the switches, and is telling you something is wet, misaligned, or shorted. Unplug the range when not in use until it’s resolved - and if clicking ever comes with a gas smell, stop using it entirely and ventilate.
How do I stop my gas stove from clicking without replacing parts?
The no-part fixes cover most cases: seat every knob fully off, dry the burner area completely after any cleaning or boilover, reseat each cap flat in its keyed position, and clean debris from around the electrodes. If clicking survives all of that, a switch, electrode, or module has genuinely failed.
