A gas stove burner that will not turn off in San Jose is an emergency — close the gas shutoff valve behind the stove immediately, ventilate the kitchen, and call PG&E at 1-800-743-5000 if you cannot stop the gas. In San Jose's ranch homes from 1970, heat buildup behind stoves during the 85°F summers softens valve stem grease, causing it to seize in the open position. The warm, dry climate accelerates grease hardening during cooler months, creating a seasonal cycle of valve degradation. With 65 local repair providers serving 970,000 residents, emergency valve service is readily available.
San Jose's warm climate creates a specific valve failure pattern. Summer heat of 85°F softens valve grease behind the stove, allowing it to migrate and redistribute. When temperatures drop, this grease hardens in new positions, potentially locking the valve stem open. The dry climate means grease doesn't get washed through by moisture as it would in humid coastal cities — it simply accumulates and hardens cyclically.
Stuck gas valve
Faulty control knob
Melted valve stem
Control board failure
Broken valve spring
The gas valve seizes in the open position from internal grease buildup, corrosion, or a failed spring. Bay Area cooking habits that include daily high-heat use accelerate valve wear. The knob turns but the internal valve does not respond — gas continues flowing regardless of knob position.
Cost: $100–$250 | Time: 45-90 minutes
The D-shaped valve stem that connects the knob to the internal valve strips from forceful turning with greasy hands. The knob rotates freely without actuating the valve. In Bay Area homes with heavy daily cooking, this develops after 5-8 years of use.
Cost: $60–$150 | Time: 30-60 minutes
Extended high-heat cooking or a grease fire can overheat the valve body, deforming internal seals. Bay Area homes with high-BTU commercial-style stoves generate enough heat to affect adjacent valve assemblies. The valve passes gas even in the OFF position.
Cost: $120–$300 | Time: 1-1.5 hours
Electronic gas stoves use solenoid valves controlled by the circuit board. A stuck relay or board failure keeps the solenoid energized (valve open). PG&E power surges in older Bay Area neighborhoods can damage the board relay, locking the valve in the ON state.
Cost: $150–$350 | Time: 1-2 hours

In San Jose, 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
