What moves it
Why two of the same job cost different amounts
These apply at the same time and in both directions. Which of them is true of your kitchen is what the on-site diagnostic settles.
-
Igniter or valve
Both produce an oven that will not light, and one costs considerably less than the other.
-
Which oven
On a dual-fuel range only one side is gas, and the electric side is a different page.
-
Whether it lights and dies
That is supervision rather than ignition, and a different part.
-
Parts availability
Igniters, thermocouples and valves for the current line are stocked.
-
How many attempts have been made
Repeated tries fill a cold cavity, and we will ventilate and check before working.

from $275 Vaulted gas oven ignition repair
The vaulted gas oven has no display, no window and no error code — La Cornue's own Château guide contains no troubleshooting section at all. So an oven that will not light is diagnosed the way gas has always been diagnosed: igniter, safety valve, thermocouple, supply, in that order and with instruments.
- A glowing igniter that never opens the valve is the classic failure here
- Safety valve and flame supervision measured rather than swapped
- Same-day priority — an oven that smells of gas is not a next-week call

About La Cornue vaulted gas oven ignition repair cost
The measurement that separates the two causes
Igniters on a gas oven are current-operated: the safety valve opens when the igniter draws enough amps, not when it looks bright. So an igniter can glow convincingly, look entirely healthy and still be well below the threshold — which is why an oven can appear to be trying hard and never light. A clamp meter on the igniter circuit answers it in about a minute and decides whether the repair is the inexpensive part or the expensive one. Without it, this job is guesswork with a bill attached.

Questions about La Cornue vaulted gas oven ignition repair cost
Why does this cost more than a cooktop burner repair?
Two reasons, and neither is the part. First, there is nothing to read: a Château gas oven has no display, so the diagnosis is a current measurement on the igniter, a millivolt measurement on the supervision circuit and a functional test on the valve. Second, it is watched through a full second cycle, because an oven that lights once and fails on the next attempt is the commonest trap on this repair.
Can I keep using the cooktop meanwhile?
Yes, as long as the burners light and hold normally and you can smell nothing. The oven's gas supply and the cooktop's share a manifold but the failures are independent. What we would ask is that you stop trying the oven and shut the range off at its valve if there is any smell.
