Gas burner clicking but won't light? We fix igniters, spark modules, and gas valves. Same-day service, 90-day warranty. Average repair cost: $80–$250. Some causes are DIY-fixable — see below.
Gas burner ignition failures in San Francisco are driven overwhelmingly by the city's persistent humidity and fog-belt moisture. When humid air condenses on the ceramic igniter tip, it creates a conductive moisture bridge across the spark gap that dissipates the electrical charge before it can generate a visible spark. Fog-belt neighborhoods in the Sunset and Richmond districts see this issue at dramatically higher rates than drier neighborhoods like the Mission or Noe Valley. Boil-over liquids — common in busy kitchens where the city's food culture drives daily cooking — flood the igniter port, requiring full disassembly to dry the electrode assembly. Victorian galley kitchens concentrate cooking steam in a small space, keeping humidity elevated around the cooktop even when the weather outside is clear. San Francisco's soft Hetch Hetchy water at 30 ppm TDS means boil-overs leave minimal mineral residue compared to hard-water cities, but the moisture itself is the primary enemy of reliable spark ignition.
San Francisco's year-round humidity above 70% condenses on ceramic igniter tips, creating moisture bridges that prevent spark generation. Fog-belt neighborhoods experience this at 2-3x the rate of drier inland neighborhoods. Victorian galley kitchens concentrate cooking steam around the cooktop. Boil-overs flood igniter ports, requiring disassembly to dry. Soft Hetch Hetchy water at 30 ppm TDS leaves minimal residue from boil-overs, but the moisture itself prevents reliable sparking.
Clogged igniter port
Failed spark module
Wet igniter
Faulty gas valve
Broken spark electrode
Normal wear on internal parts is the leading cause of cooktop burner wont ignite issues. Regular use over 5-10 years gradually degrades moving parts and seals.
Cost: $130–$255 | Time: 60-90 minutes
Control board malfunctions, faulty sensors, or wiring issues can cause burner wont ignite symptoms. Power surges and age-related degradation are typical triggers.
Cost: $156–$304 | Time: 45-75 minutes
Debris, mineral deposits, or foreign objects can restrict normal operation. This is often preventable with regular maintenance.

Gas burner ignition repairs cost $80-$250 in the Bay Area. Spark module replacement runs $100-$175 installed. Individual igniter replacement averages $80-$150. In many SF cases, thorough drying and cleaning resolves the issue without parts replacement — saving $50-$100 versus a parts repair.
In San Francisco, salt-laden marine air and persistent fog deposit corrosive moisture on metal surfaces and electronics. This can affect your appliance's spark electrode: salt corrosion on the electrode tip widens the spark gap, causing weak or absent ignition sparks Clean electrode tips with fine sandpaper when clicking becomes weak; keep burner caps dry
In San Francisco, sustained relative humidity above 60% promotes mold growth, condensation on cold surfaces, and accelerated corrosion. This can affect your appliance's spark module (gas): moisture infiltrates the spark module housing, causing continuous clicking after burners are lit or failure to spark at all Keep the area under burner caps dry; if clicking persists after cleaning, the spark module may need replacement
In San Francisco, very low mineral content (<60 ppm tds) or sodium-softened water causes over-sudsing, rubber swelling, and reduced detergent rinsing. This can affect your appliance's glass surface (ceramic): soft water boil-overs are harder to remove from glass-ceramic surfaces because the low mineral content etches the glass during evaporation Clean boil-overs immediately with a ceramic cooktop cleaner; do not let soft-water residue dry on the surface
