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 issues in Sunnyvale are uncommon compared to coastal cities thanks to the dry Silicon Valley climate, but when they occur, the root causes are typically boil-over mineral deposits and aging Eichler-home electrical connections. San Jose Water Company supply at 250 ppm TDS leaves moderate calcium deposits from boil-overs that insulate igniter electrodes over months of accumulation. Many Sunnyvale Eichler homes have distinctive post-and-beam construction with radiant floor heating that shares gas supply with the cooktop, creating pressure competition during winter heating. Premium cooktops from Wolf and Thermador in tech-worker homes require consistent gas pressure that marginal Eichler-era supply lines cannot always deliver. The dry climate does keep igniters free from moisture corrosion, extending their typical lifespan to 10-12 years. Dust accumulation in the dry air settles into igniter ports and burner orifices, gradually restricting the spark gap over time without the moisture to wash it away.
Sunnyvale's dry climate prevents moisture corrosion on igniters but allows dust accumulation in igniter ports. San Jose Water at 250 ppm TDS deposits minerals from boil-overs. Eichler radiant floor heating competes with cooktop gas supply. Premium cooktops in tech-worker homes demand consistent gas pressure that Eichler-era supply lines may not deliver. Dry conditions extend igniter lifespan to 10-12 years.
Clogged igniter port
Failed spark module
Wet igniter
Faulty gas valve
Broken spark electrode
Normal wear on internal parts is the leading cause of gas stove burner wont ignite issues. Regular use over 5-10 years gradually degrades moving parts and seals.
Cost: $140–$270 | 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: $168–$320 | Time: 45-75 minutes
Debris, mineral deposits, or foreign objects can restrict normal operation. This is often preventable with regular maintenance.

Gas ignition repairs average $80-$250 in the Bay Area. Sunnyvale's dry climate makes igniter replacement less frequent than coastal cities. Most ignition issues resolve with cleaning and gas pressure adjustment. Eichler-home gas supply upgrades ($200-$400) resolve chronic pressure competition.
In Sunnyvale, wide day-night temperature swings (30f+ delta) stress thermal expansion joints, thermostat cycling, and sealed-system pressures. This can affect your appliance's flex gas connector: thermal cycling fatigues the corrugated stainless steel gas connector, increasing the risk of micro-cracks at the flare fitting Have the gas connector inspected during annual service; replace corrugated connectors every 10 years proactively
