Write the code down in full, with its number. If it comes back, it needs a visit. ### Can I find out what the number after Er means on my CornuFé? La Cornue does not publish a list of those numbers for owners. Write the full code down and share it when you book, since it helps the technician narrow the search. ### Can my CornuFé induction top still be used with an Er code? La Cornue says the problem cannot be fixed by the user, so avoid using the affected zone until it is checked. ### Is Er on a CornuFé usually a board or a coil? The guide does not say, and the number is what points one way or the other. That is why the full code matters. --- **[Read on the site: La Cornue CornuFé induction top showing Er and a number](https://stoverepair.center/error-codes/la-cornue-er/)** **[Book a visit with StoveRepair.center](https://stoverepair.center/schedule/)**
