# La Cornue appliance control board repair cost

### The most expensive sentence in appliance repair

“It is probably the board.” On a La Cornue it usually is not: three quarters of this site’s model pages describe appliances with no electronics to fail. Where there are electronics, this figure buys the discipline of proving the supply, then every sensor, then every load, before the board is even quoted — and of writing the measurements down so you can see why. It also buys an honest lead time, because a control for a hand-built appliance is not a shelf item and finding that out after the old one is removed is nobody’s idea of a repair.

What moves this figure

from $345, and it is the last suspect rather than the first

A board condemned with a failed sensor attached fails again in a week

Lead time stated before anything is ordered

Which platform

An induction generator, a multifunction oven control, a Tourelle board and a hood control are four different parts.

Whether the inputs were proved

Supply, sensors, loads. This is where most board replacements should have stopped.

Whether there is an Er number

The one message that points here directly, and it is worth writing down exactly.

Board availability

Current-platform boards are obtainable; an older configuration may be a long wait or unavailable.

Whether something took it out

A shorted load or a bad supply will take a new board with it on the first cycle.

### Why is a board the last thing you look at?

Because on this make it is rarely the problem and always the expensive answer. Most of the line has no electronics at all. Where there are electronics, the things in front of them — supply, connection, sensors, coils, elements — fail far more often and are far cheaper, and a board fitted with one of those still faulty fails again immediately. Measuring in order is not caution, it is arithmetic.

### What if the board is not available?

Then we tell you, in writing, rather than leaving it open. On a current platform this is unlikely. On an older configuration it happens, and the honest options are a repair to the existing board where that is genuinely possible, or living with a reduced function — a range with one working oven is still a range. What we will not do is fit something approximate into an appliance like this.
