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 Stove burner won't ignite repair typically costs $80 to $250. Some causes are DIY-fixable, but professional diagnosis is recommended if the problem persists. Most repairs are completed in 45 min-1.5 hours with a free diagnostic visit.
South San Francisco sits squarely in the Peninsula fog belt, experiencing persistent marine layer, strong winds, and cool temperatures that keep summer highs around 64 degrees. This makes it one of the dampest environments for gas stove ignition components on the entire Peninsula. Tract homes from the 1940s through 1960s line the hillsides with bay views, and these older structures with single-pane windows allow fog moisture to penetrate kitchens where it condenses on igniter electrodes and spark module contacts. Strong winds carry salt and moisture from the Pacific gap at San Bruno Mountain, accelerating corrosion on all exposed metal components. Cal Water supplies very soft water from Crystal Springs at 40 TDS, so mineral buildup is not a concern — moisture corrosion dominates the ignition failure picture. With 7 competitors serving 66,174 residents and the biotech campus growth bringing newer workforce housing with modern appliance packages, the repair market spans vintage damp-affected homes and newer installations.
South San Francisco's 66,174 residents live in one of the Peninsula's dampest climates, with persistent fog and strong Pacific winds creating aggressive conditions for gas stove ignition components. Hillside tract homes from the 1950s and 1960s orient toward bay views at the expense of kitchen ventilation, trapping moisture inside. The biotech campus growth is bringing newer construction with modern appliance packages, but most of the housing stock remains mid-century with vintage gas infrastructure. Cal Water's very soft Crystal Springs supply at 40 TDS eliminates mineral concerns, keeping diagnosis focused on moisture and salt corrosion.
Clogged igniter port
Failed spark module
Wet igniter
Faulty gas valve
Broken spark electrode
The spark igniter tip accumulates grease and food residue from daily cooking, insulating the spark gap. Bay Area humidity deposits a moisture film on the ceramic insulator, further reducing spark strength. Heavy cooking households in the Bay Area may need igniter cleaning every 6-12 months.
Cost: $60–$150 | Time: 30-60 minutes
The tiny holes around the burner cap clog with food debris, boil-over residue, and grease. Even if the igniter sparks, gas cannot reach the spark point for ignition. In busy Bay Area kitchens where multiple burners run simultaneously, boil-overs are frequent and clog ports of adjacent burners.
Cost: $60–$120 | Time: 30-45 minutes
The spark module generates high-voltage pulses to all igniters simultaneously. When it fails, some or all burners won't spark. PG&E power fluctuations in older Bay Area homes can damage the module. If no burners click, the spark module has likely failed rather than individual igniters.
Cost: $100–$220 | Time: 45-75 minutes
The gas valve for a specific burner can stick closed or the PG&E gas supply pressure may be low. Older Bay Area homes with original gas lines sometimes have restricted flow from pipe corrosion. The igniter clicks and sparks, but no gas reaches the burner for ignition.
Cost: $120–$280 | Time: 45-90 minutes

Gas stove ignition repairs in South San Francisco cost $80 to $250, with corrosion-related component replacements trending toward the higher end. The 7 local competitors provide reasonable coverage for a mid-size Peninsula city. Fog-belt conditions mean igniter replacement frequency is 20 to 30 percent higher than in drier inland cities.
In South San Francisco, salt-laden marine air and persistent fog deposit corrosive moisture on metal surfaces and electronics. This can affect your appliance's thermocouple: salt deposits on the thermocouple tip create an insulating layer, causing flame-sensing failures and gas shutoff Clean the thermocouple tip with fine emery cloth annually; never use water or cleaning solutions
In South San Francisco, sustained relative humidity above 60% promotes mold growth, condensation on cold surfaces, and accelerated corrosion. This can affect your appliance's igniter electrode: moisture on the ceramic igniter insulator allows the spark to track down the side instead of jumping to the burner, preventing ignition Dry the electrode and surrounding area if the burner fails to light; a hair dryer on low can remove trapped moisture
In South 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 oven interior: soft water steam clean cycles leave a sodium residue film on interior surfaces that can smoke during subsequent cooking Use distilled water for steam clean functions; wipe interior with a damp cloth after the cycle completes
