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.
-
What the display shows
Nothing at all means supply. U400 latched means connection. Not the same call.
-
What changed
A breaker replaced, a range moved, kitchen electrical work. This problem has a date nearly every time.
-
Whether it trips protection
A circuit that trips repeatedly is tested rather than reset.
-
Whose work it is
If the problem is upstream of the appliance, our finding is a report for whoever owns that work.
-
Whether the control is genuinely damaged
Sometimes a bad supply has taken the control with it, and that is quoted separately.
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 $295 Cooktop control and wiring repair
U400 latched on the display, a hob with no display at all, a fuse or residual-current device that trips repeatedly. All three are supply-and-connection problems in the maker's own words, and all three turn up after something in the house changed.
- The appliance connection checked against the maker's specification
- Over-voltage and lost supply distinguished from a dead control
- Findings written down when the problem is upstream of the range

About La Cornue cooktop control and wiring repair cost
The figure that sometimes buys a report instead of a repair
U400 means the cooker has been incorrectly connected, in La Cornue's own words, and that makes it one of very few messages on this make where the honest outcome may be that your appliance is undamaged. The visit measures the supply and the connection against the maker's requirements document, establishes what changed and when, and writes the finding down. Where the problem is upstream that report is the deliverable — and it is worth considerably more than a part fitted to work around somebody else's wiring.

Questions about La Cornue cooktop control and wiring repair cost
If nothing in my range is broken, do I still pay?
Yes, and we would rather say that plainly than surprise you. What you are paying for is the measurement and the written finding — which is precisely what lets you go back to whoever replaced the panel or moved the range, and precisely what stops you buying a generator board you did not need. A visit that ends in "your appliance is fine and here is the evidence" is a successful visit.
Can I reset U400 myself?
There is nothing to reset. The maker's own text is that the control switches off after about a second and the code stays permanently displayed — it is designed not to be cleared until the connection is right. Power-cycling it proves nothing and tells you nothing.
