# La Cornue appliance control board repair

### About boards, and why they are the last suspect here

Three quarters of the models on this site have no electronics to fail at all. Where there are electronics — an induction generator, a multifunction oven control, the Tourelle, a motorized hood control — the things in front of them fail far more often and cost far less: supply, connection, sensors, coils, elements. So the supply is proved, then every sensor, then every load, and the board is quoted last and with its lead time, because a control for a hand-built appliance can ship from France.

What this involves

Supply, sensors and loads eliminated before a board is blamed

Er numbers documented and quoted, since only the maker's own board clears them

Lead time stated up front on a hand-built appliance

Prove the inputs first

A board condemned with a failed sensor still attached comes back as a second visit and a second bill.

Prove the supply

Voltage and connection at the appliance. A board blamed for a supply problem fails again in a week.

Prove the sensors

Every input measured. This is where most board replacements should have stopped.

Prove the loads

Elements, coils, motors. A shorted load takes a new board with it on the first cycle.

Quote the board with its lead time

On a hand-built appliance a control can ship from France. The owner is told that before the order, not after.

### Why not just fit a board and see?

Because a board fitted with a failed sensor or a shorted load still attached fails again on the first cycle, and then you have paid for two. Measuring in order is arithmetic rather than caution: the cheap parts are also the likely ones.

### What if the board is not available?

We tell you in writing rather than leaving it open. On a current platform it 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 a reduced function — a range with one working oven is still a range. We will not fit something approximate into an appliance like this.
