Gas stove repair guides: igniter troubleshooting, gas leak detection, flame adjustment, and safety inspections for California homes.
Gas stoves demand a different approach from any other kitchen appliance because they combine electrical controls with an open fuel supply. A burner that clicks endlessly but won't light is annoying; a gas valve that leaks silently is dangerous. Our guides separate the two categories clearly: electrical ignition problems you can safely diagnose and often fix yourself, and gas supply issues that require a licensed technician and may warrant an immediate call to your gas utility.
The most common gas stove repair is igniter replacement — the ceramic spark electrode or hot-surface igniter wears out over time and either clicks without sparking or glows without opening the safety valve. We cover the testing procedure for both types, the specific igniter part numbers for the top-selling GE, Samsung, LG, and Frigidaire models, and the typical cost range for professional replacement. For burner flame problems — yellow tips, uneven rings, or weak output — we walk through the gas pressure adjustment and orifice cleaning procedures.
Earthquake preparedness adds a layer to gas stove safety in the Bay Area and Sacramento. Flexible gas connectors, automatic seismic shut-off valves, and post-quake relighting procedures are covered in dedicated guides. California law requires flexible connectors on all gas appliances, and our guides explain how to verify compliance during any repair visit.

A Viking burner that won't light is most often a worn igniter. One test splits the diagnosis: if no burner clicks, the spark module is dead; if one won't catch, it's that burner's igniter or ports.
Most likely: a failed igniter — it is the most frequently replaced part when a Thermador burner won't light. On the cooktop that is the ceramic spark electrode; in the oven it is the hot-surface igniter that must glow bright (reaching 1800-2500 degrees F) to draw enough current to open the gas…
A brief whiff as a burner lights is normal, but a persistent gas smell, or any odor when every burner is off, is not. The most common real cause is a loose flexible gas connector, then a burner not fully lighting, a valve that will not close, a cracked burner tube, or the oven safety valve seeping. If the smell is strong, shut the gas, evacuate, and call the utility.

A Viking gas burner that keeps burning with the knob off is a safety hazard — shut off the gas at the wall valve immediately. The usual cause is a grease-fouled gas valve, sometimes a damaged knob or a broken valve spring. Safe diagnosis steps.
