Gas stoves are reliable and familiar, but unexpected issues can catch anyone off guard. One of the more frustrating ones is when a burner keeps clicking or sparking even after the flame is lit and the knob is turned back to the right setting. We’ve handled this issue in many kitchens while providing appliance repair in Glendale, and we know it can leave people feeling uncertain about using their stove safely. Let’s break down what causes this and what steps can prevent it from getting worse.
Moisture Trapped in the Ignition System
Steam from boiling pots and liquids spilled on the cooktop often flow beneath the burners without being noticed. That moisture can settle into the ignition switches or burner base. As a result, the igniter keeps sparking because it detects the presence of fluid and assumes the flame hasn’t caught.
We usually find this problem happens more often in kitchens where heavy cooking involves water or sauces. Even wiping the top of the stove doesn’t remove water trapped inside the knobs or igniter channels. Sometimes, the moisture dries out naturally after a few hours. However, if it stays inside too long, corrosion can develop around the switches.
To avoid long-term problems, we recommend removing burner caps and letting the components air dry completely. If that doesn’t help, a deeper check of the burner base and ignition system might be needed. If the issue persists for more than a day, stove repair in Burbank can be the safest next step to prevent damage.
Ignition Switch Stuck in the “On” Position
Some gas stoves rely on mechanical switches behind each knob to control the spark function. If that switch becomes sticky or damaged, it may stay in the “on” position even after turning the flame down or off. That’s why the burner keeps clicking even when nothing seems wrong from the outside.
We often see this issue in older cooktops or when cleaning agents leak into the control panel. While it may not cause immediate danger, the clicking sound continues nonstop. This can wear out the ignition module over time or even short-circuit nearby wiring if not handled quickly.
Turning off the circuit breaker to stop the power temporarily can help verify whether it’s an electrical issue or not. If the clicking stops after power is disconnected, the switch is likely stuck. Replacing that switch is not a complicated job, but it does require careful access behind the control panel. Appliance repair in Glendale includes this type of work regularly for local homes with aging or worn-out stoves.
Faulty Igniter Module Causing Constant Sparking
Another reason burners keep trying to light is a faulty igniter module. This small control box sends the signal to spark when the knob is turned. When it starts to fail, it may send constant signals even after the flame is already burning.
We notice this most often in stoves that have been in use for several years. Constant heat and grease buildup near the module eventually cause electrical resistance or shorts. When this happens, all burners might click together—even the ones not in use. That’s a sign the problem is coming from the module, not individual burner parts.
You can sometimes test this by unplugging the stove and watching if the clicking stops. If every burner stops at once, the module is almost always the reason. Igniter modules are not universal, so it’s best to check model compatibility before ordering. In many cases, having the appliance repair experts in Glendale inspect the stove helps avoid unnecessary part replacements or extra labor.
Dirt and Grease Blocking the Flame Sensor
Even if the flame lights correctly, the igniter might not sense it if there’s dirt on the electrode tip. Grease and soot buildup interfere with the signal that tells the igniter to shut off. So, it keeps clicking, believing there’s no flame present.
This problem is more common in stoves used for frying or grilling. We’ve seen cases where just a thin layer of grease caused persistent clicking after every use. Cleaning the tip with a soft brush or a bit of rubbing alcohol can restore proper contact.
Avoid using metal tools or harsh scrubbing pads since that can damage the sensor tip. It only takes one scratch to make the spark jump to the wrong place. A gentle wipe once a week often keeps the system working reliably. However, if the tip looks worn or corroded, it may be time to replace it. If you’re not sure, our team at Quick & Pro Appliance Repair Glendale can take a look and confirm what’s needed.
Burner Cap Out of Alignment or Improperly Seated
A common but often overlooked issue is the burner cap sitting slightly off-center. When it’s not aligned properly, the flame doesn’t spread evenly, and the igniter may keep clicking because the sensor doesn’t detect the right flame path.
We find this happens after deep cleaning or when users remove caps to dry moisture. Even a small shift in position can confuse the sensor. Luckily, the fix is simple: lift the cap and reseat it until it rests flush with the burner base. You’ll often hear the clicking stop right away once the cap is in the right spot.
If your stove has grates that don’t lock in place, they might also push the cap out of alignment when bumped. Always check burner parts after moving the grates or adjusting pots. If realignment doesn’t solve the problem, the burner head itself may be worn or warped. In that case, professional appliance repair in Glendale can help find matching replacement parts.
Power Surge or Control Board Malfunction
Sudden power interruptions or voltage surges can confuse the stove’s internal electronics. If your model uses a control board instead of basic mechanical igniters, it may get stuck in a loop where the igniters keep sparking repeatedly.
We’ve seen this happen after storms or local outages. The board gets power back, but internal settings stay frozen in ignition mode. Restarting the stove at the breaker sometimes clears the error. If it doesn’t, the board may need reprogramming or replacement.
Unlike basic gas stoves, those with touchpad controls or digital timers are more sensitive to power inconsistencies. To protect your unit, using a surge protector made for kitchen appliances can help. If you’re unsure whether your stove uses a control board or manual components, it’s worth having our technicians inspect it. That quick visit could save you from replacing the wrong part or ignoring a warning sign. If needed, reach out through contact our appliance repair team to get help.
When to Disconnect and Wait Before Troubleshooting
Sometimes, the clicking isn’t from damage but a result of the system taking time to shut off after cooking. We often explain this when customers call after simmering a pot for hours or using multiple burners. The ignition can stay active briefly as the stove cools.
In this case, turning off the burner and waiting ten to fifteen minutes can be enough. If the clicking still continues after that, then other causes may be involved. Disconnecting the stove from power for a short time can reset the igniter control in some models.
It’s important not to keep twisting the knobs or lighting the burner repeatedly. That could cause wear to the spark electrode or let more gas through the valve. Instead, unplug the unit or turn off the circuit breaker and give it time. If it’s still clicking after 30 minutes, something likely needs repair. We’re always available to assess it safely and help get everything working right again.
FAQs
Why does my stove keep clicking even when it’s off?
The ignition switch may be stuck or the igniter module might be malfunctioning. It keeps sparking as if trying to light a burner.
Is it dangerous if the burner keeps clicking?
It’s not usually dangerous right away, but constant sparking can wear out components or cause short circuits. It’s best to check the source quickly.
Can cleaning the burners stop the clicking?
Yes, especially if grease or moisture is blocking the sensor. A good cleaning often solves the problem when buildup is the cause.
What if only one burner keeps clicking?
That usually means a problem with that burner’s cap, igniter tip, or switch. The issue is likely not with the entire stove.
Do I need to replace the whole igniter system?
Not always. Many times, just the switch or the module is the problem. A full replacement isn’t usually necessary unless there’s damage.
