Burner won't light
A cooktop burner that won't light splits by fuel type, with gas burners failing through a different set of mechanisms than electric burners. Gas burners use a spark igniter that clicks rapidly to ignite gas flowing through the burner ports — failures typically involve food debris or spilled liquid clogging the ports, a misaligned burner cap blocking the ignition path, moisture on the igniter electrode (especially after cleaning), or a worn electrode that's lost its spark. Electric burners don't have ignition at all; they heat resistively when current flows through a coil or radiant element. Electric burner failures are usually element failure (the coil burns through and opens the circuit) or receptacle corrosion (the plug-in socket that powers the coil has corroded contacts). Before any disassembly, pull the burner cap and burner grate, clean the area thoroughly, and reseat the cap — this fixes roughly half of 'burner won't light' complaints on gas cooktops.
Safety
Critical- Kill the breaker before electric cooktop work: Electric cooktops run on 240V circuits with two breakers. Turn off both before removing a coil or accessing the receptacle. Voltage at the coil terminals is lethal — verify with a multimeter after killing the breaker. The receptacle can remain energized even with the coil removed.
- Gas-bearing work requires a licensed professional: Cleaning burner ports, wiping igniter electrodes, and reseating burner caps are DIY-friendly. Gas-bearing work — orifice cleaning, valve replacement, regulator adjustment, gas line repairs — is restricted by local code in most jurisdictions and requires licensed service. Do not attempt to modify gas components yourself.
- Stop if you smell gas during diagnosis: If you smell gas during cleaning, inspection, or testing, stop immediately. Don't create sparks (including turning knobs or operating electrical switches nearby). Leave the area, open windows, and call your gas utility's emergency line from outside. Don't return until the utility confirms the area is safe.
- Burner surfaces stay hot after use: Gas burner caps and electric cooktop coils remain hot enough to cause burns for 15-20 minutes after use. Allow full cooldown before cleaning burner ports, handling coils, or reaching into the burner area. Use a timer if needed to ensure components are cool.
How to approach this
Start with cleaning and cap alignment on gas cooktops. Remove the burner grate, lift off the burner cap, and clean food debris and spilled liquid from the burner ports (the small holes around the burner base where gas emerges). Wipe the igniter electrode — the small ceramic spike near the burner — dry with a clean cloth if there's any visible moisture. Reseat the burner cap carefully; misaligned caps block the ignition path and are the cause of many 'sparks but no ignition' complaints. Turn the knob to ignite — you should hear rapid clicking and see a spark at the electrode. If no clicking occurs, the spark module has failed or power isn't reaching it. If clicking occurs but gas doesn't ignite, check whether other burners light (confirms gas supply). On electric cooktops, lift the suspect coil out of its receptacle and inspect for visible breaks or burned sections. Swap the suspect coil with a working one from another position; if the working coil also fails in that position, the receptacle has corroded contacts. Test the coil itself for continuity — 10-50 ohms working, infinite means a failed open element.

maintenance
The ceramic glass cooktop requires gentle cleaning - allow to cool completely and never apply cold water to hot surface as it can cause cracking.

Common causes
Ordered by how frequently each component is involved, based on OEM manual analysis.
Food debris or moisture in burner ports (gas)
Most commonThe small holes around a gas burner base (the ports) can clog with food debris, spilled liquid, or dried residue from boil-overs. Moisture from cleaning can sit in ports briefly and disrupt gas flow. Clean the burner cap and ports with a dry cloth or a toothpick; do not use metal pins that could enlarge the ports. This is the single most common cause of gas burners failing to light and typically costs nothing to fix.
Failed surface element (electric)
CommonElectric coil burners contain a resistive heating element that fails open over years of thermal cycling. A visible break in the coil or a burned-black section indicates failure. Swap the coil with a burner from another position to confirm — if the working coil fails in the suspect position, the receptacle has failed instead. Replacement coils run $20-50 and install by plugging into the socket.
Misaligned burner cap (gas)
CommonThe burner cap sits on top of the burner base and directs gas flow to the ports. If the cap is seated slightly off-center or tilted (after cleaning, after the cooktop was moved, or from impact), gas doesn't reach the igniter electrode properly. The spark happens but no ignition occurs. Lift the cap, clean any debris, and reseat it squarely on the burner base — the cap should sit flat with no rocking.
Failed spark igniter electrode (gas)
CommonThe igniter electrode is a ceramic spike with a metal tip near each burner. Over years, the ceramic can crack, the metal tip can corrode, or the wire connection can fail. Symptoms include weak sparking, erratic ignition, or no spark at all while other burners still work. Replacement electrodes are typically $15-30 each and are accessed by lifting the cooktop surface.
Failed infinite switch (electric)
Less commonThe infinite switch is the control behind each burner knob that cycles power on and off to produce variable heat settings. When it fails, the burner may work only at certain settings (high only, off only) or not at all. Swap with a working infinite switch from another burner to confirm. Replacement switches run $15-30 and install behind the cooktop's front panel.
Corroded receptacle or burner socket (electric)
Less commonThe receptacle is the plug-in socket that powers each coil burner. Spilled liquids can seep in, and thermal cycling can oxidize the contacts. A corroded receptacle passes reduced current (burner runs weak or not at all) even when the coil tests good. Diagnose by swapping a known-good coil into the position; if the known-good coil also fails, the receptacle is the issue. Replacement receptacles run $20-40.
