What's Included
- Spark module replacement for total ignition failure
- Electrode and electrode wire service for burner-specific ignition failure
- Burner port cleaning and gas manifold pressure verification
- Gas valve diagnosis and replacement
- Air shutter and combustion air adjustment
- Gas type conversion with La Cornue-specified orifice kits
- Brass burner cap and control knob inspection
The La Cornue gas rangetop delivers the same handcrafted French cooking performance as the Château range's surface section — polished brass burner caps, powerful gas output, and the precision that professional chefs demand. When a burner misfires or refuses to light, the fault needs a technician who understands La Cornue's gas ignition architecture and respects the quality of the components involved.
La Cornue Rangetop Problems We Fix
- Total ignition failure (all burners): spark module failure or 120V power supply issue. Spark module replacement from $225.
- Single burner will not ignite: damaged electrode or broken electrode wire. Electrode replacement from $155.
- Burner lights but flame is low or weak: restricted gas flow, clogged ports, or partially-closed gas valve. Port cleaning and pressure check from $185.
- Yellow or orange flame: incomplete combustion due to incorrect gas type configuration or blocked air shutter. Safety-critical — requires immediate service. From $195.
- Burner keeps clicking after lighting: moisture or food residue at the electrode. Cleaning resolves most cases; spark module service from $225 if persistent.
- Gas smell without visible flame issue: gas valve leak or fitting failure. Gas leak investigation from $185 — treat as an emergency.
La Cornue's Gas Heritage
La Cornue has been building gas cooking appliances since 1908. The company's Château Gas Range — the original product that established La Cornue's reputation — is still manufactured to order in France today. That heritage informs every aspect of the brand's gas burner design: the heavy brass caps, the precision-drilled orifices, and the gas valve assemblies are all engineered to perform at a level that mass-market alternatives cannot match. They also require specialist knowledge to service correctly.
Gas Type Conversion
La Cornue gas rangetops are factory-configured for either natural gas or LPG. If the appliance has been moved between homes with different gas supplies, or if it was incorrectly installed, a yellow flame indicates a gas type mismatch — a safety issue requiring conversion with La Cornue's factory orifice kit.
