# 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.

What moves this figure

from $275, and the second cycle is part of the job

A glowing igniter with no flame is the classic failure here

Same-day priority — a sealed cavity is not somewhere to leave gas

Igniter or valve

Both produce an oven that will not light, and one costs considerably less than the other.

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.

### 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.
