Repair cost
La Cornue gas valve and thermocouple repair cost
Two safety-critical parts and a leak check on every joint that was opened. Mechanical valves on a made-to-order manifold rather than a common assembly, which is what separates this figure from the equivalent on a mass-market range.
- From $95 diagnostic, credited to the repair
- 59 cities and neighborhoods covered
- OEM parts available on order
- In writing the price, before anything is opened

On the labor we performed
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.
-
How many valves
The labor of reaching the manifold is the same for one valve or four, which is why the diagnostic works all of them.
-
Rebuild or replace
A valve stiff with residue can sometimes be rebuilt. A galled taper cannot, and we will say which.
-
Which valve
An oven valve is further in than a surface burner valve.
-
Whether the thermocouple is involved
Flame supervision and the valve are two parts that produce one symptom.
-
Parts availability
Valves for the current line are sourced domestically; a valve specific to one older configuration may not be.
The work itself
What we actually do
The job behind the figure: what it involves, when a symptom points at it, and what we check first.
-
from $265 Gas valve and thermocouple repair
The safety chain: a valve that will not hold open, a thermocouple that no longer tells it to, a knob that has gone stiff or will not shut off cleanly. This is the part of a gas range where nothing gets improvised and nothing gets left half-diagnosed.
- Safety valve and flame supervision tested as a system
- Stiff or leaking knob valves rebuilt or replaced, never lubricated over
- Leak-checked at every joint that was opened

About La Cornue gas valve and thermocouple repair cost
The one figure on this site we will not discount
Not for commercial reasons. A safety valve, a thermocouple and a leak check are the components that decide whether unlit gas can enter your kitchen, and there is no version of this job with a step left out. The figure covers measuring the supervision signal against what the valve needs, proving the valve holds and shuts, testing every joint that was opened, and relighting and watching every burner affected. If that sounds like a lot for one repair, it is — and it is the right amount.

Before you book
Questions about La Cornue gas valve and thermocouple repair cost
Can you just adjust it instead?
No. A gas valve is either sealing or it is not, and the two things people mean by "adjust" — lubricating a stiff taper and easing a seat — are both ways of hiding a problem for a few weeks. If a valve is passing gas with its knob off it comes out, and if it is stiff it is rebuilt or replaced.
Is this covered by anything?
On a range still inside its warranty, possibly, and the report we leave is written so it can be used for a claim — part reference, measured findings, cause. Out of warranty it is an ordinary repair, and on an appliance built to be serviced for decades it is a proportionate one.
