A burner that won’t click or light can stop dinner in its tracks. We understand how frustrating that is. You turn the knob, expect that familiar ticking sound and flame, but nothing happens. This kind of issue is often simple to troubleshoot if you know where to look first.
Let’s walk through what we usually check when a cooktop burner refuses to ignite. Whether it’s a gas connection issue, an electrical fault, or just built-up grime, the problem is often fixable with a few basic steps.
Check the Burner Cap and Assembly
The first place we check is the burner itself. Most gas cooktops rely on a metal cap that sits on top of a burner head. If that cap is misaligned or upside down, the gas may still flow, but the spark won’t catch correctly. As a result, the burner stays silent or emits gas without ignition.
We always recommend removing the burner cap and realigning it to ensure it’s sitting properly. To clarify, this small adjustment can make the difference between no spark and full ignition. While you’re at it, clean any food residue off the burner head using a stiff brush or a paper clip to unclog the small gas holes.
This is a fast and easy first step that can save you from calling for help. For instance, we’ve seen customers in cooktop repair Pasadena resolve their issue on the spot just by reseating the cap properly.
Inspect the Igniter for Damage or Moisture
If the cap is secure but the burner still doesn’t click, the next thing we check is the igniter. The igniter is a small ceramic or metal tip located near the burner that creates a spark. If you don’t hear the familiar clicking sound when you turn the knob, the igniter might be dirty, wet, or even cracked.
Moisture is a common issue, especially after cleaning the cooktop. Even a few drops of water around the igniter can prevent it from firing. Therefore, we usually suggest using a dry cloth or cotton swab to gently blot the area and then waiting a few hours before trying again. If the igniter is visibly cracked or corroded, it may need replacement.
Sometimes, a dirty igniter is the only problem. For example, grease buildup can block the spark, causing the burner to stay silent. A careful cleaning can often bring it back to life without needing parts.
Test for Gas Flow and Smell
If the igniter clicks but there’s no flame, we turn our attention to the gas flow. First, we check whether the gas valve behind the appliance is fully open. It might seem obvious, but people often bump or partially close it during cleaning or moving.
To check if gas is reaching the burner, we gently try to ignite it with a long lighter. If it lights this way, then the issue is clearly with the ignition system, not the gas supply. However, if it doesn’t light at all and there’s no gas smell, then gas flow might be blocked.
On the other hand, if you do smell gas but nothing happens when turning the knob, it could be dangerous. In such cases, it’s safest to turn off the valve and seek help right away.

Look at the Knob and Switch System
Another overlooked component is the ignition switch built into the knob. When you turn the knob on a modern gas cooktop, it pushes a small switch that sends power to the igniter. If that switch fails, the igniter won’t click, even if everything else is working.
To test this, we turn on a different burner. If other burners click normally, the issue is likely isolated to that one switch. This helps narrow down the problem without taking the appliance apart. If none of the burners click, the issue might be electrical or related to a tripped breaker.
We’ve helped many homeowners troubleshoot these issues quickly just by comparing burner responses. Similarly, keeping an eye on whether other knobs make the igniter click can help you isolate the faulty one.
Check for Power Supply Problems
Gas cooktops still rely on electricity to operate the igniters. So if your cooktop suddenly stops clicking altogether, even when all knobs are turned, the appliance might have lost power. Start by confirming that it’s plugged in. Some outlets have built-in circuit breakers that can trip easily during a power surge or if there’s moisture in the line.
After that, we often recommend checking your home’s breaker box. Look for any flipped switches, especially those labeled for the kitchen or cooktop. Reset them and test the cooktop again. If it works, that was likely the cause.
Power issues are common after storms, remodeling projects, or after plugging in high-demand appliances. If this sounds familiar, it might be time to contact us for help. You can Contact Us to arrange a visit and make sure everything is set up correctly and safely.
Keep the Area Clean to Prevent Repeat Issues
We’ve seen that prevention makes a big difference when it comes to burner issues. Regular cleaning is one of the best ways to keep everything running smoothly. That is to say, food spills, oils, and cleaners can get into tiny gaps and clog the ignition system.
Every few days, we recommend lifting the grates and wiping around the burners with a damp cloth. Then, allow the area to dry completely before using the stove again. Use a toothbrush or small nylon brush to clear out hard residue. Most importantly, don’t pour water directly over the cooktop surface during cleaning, especially near the igniters.
In the same vein, don’t forget to let everything cool down first. Trying to clean while the burner is hot can cause burns or even damage fragile parts.
When You’ve Tried Everything and It Still Won’t Light
Sometimes, even after checking the burner cap, igniter, gas flow, knobs, and power, the burner still won’t ignite. That’s when we step in. Diagnosing deeper issues often requires tools to measure voltage or disassemble the unit safely.
In these cases, we inspect the internal wiring, the igniter module, or the safety valves that regulate gas. Faulty modules are common in older cooktops or in homes with frequent electrical issues. Replacing them usually restores full function.
We’ve handled dozens of these cases through our cooktop repair Pasadena service. Often, it turns out to be something small that just needs an experienced hand.
If you’re still unsure what the issue is, or if the smell of gas makes you uncomfortable, don’t wait. We’re here to help. Reach out and Contact Us so we can check things over and get your cooktop working again.
Frequently Asked Questions
Why does only one of my burners not click while the others do?
This usually means the ignition switch or igniter for that specific burner is faulty. The rest of the system is working, so it’s not a power or gas issue.
Can a wet cooktop cause the igniter to fail?
Yes. Moisture around the igniter can prevent it from sparking. It’s a common problem after cleaning. Always dry the cooktop completely before turning it on again.
Is it dangerous if I smell gas when the burner won’t light?
It can be. If you smell gas and there’s no flame, turn off the gas valve and ventilate the room. Do not attempt to light it again until it’s inspected.
Do I need a technician to replace a faulty igniter?
Replacing an igniter is possible on your own if you’re experienced with appliances, but we recommend letting a technician handle it to avoid damaging other components.
What’s the most common reason burners stop clicking?
Grease and food debris on the igniter tip are the top causes. A quick cleaning with a brush or cloth usually restores normal operation.
