What d E means

On JennAir electric radiant and touch-control cooktops, d E shown in the OFF position means demo mode is on. In demo mode the cooktop does not heat up and its functions do not come on, even though the display and keys respond. It is a showroom setting and not a breakdown. The cooktop cannot cook until demo mode is switched off.

Common causes of d E

  • Demo mode switched on
  • Setting changed during a power-up key press
  • Cooktop left in showroom setting after installation
✓ One safe check you can try

1. Confirm that all controls are off and that d E shows. 2. Do a short power reset: breaker off, one minute, breaker on. 3. Look at the display after power returns. 4. If d E remains, do not hold keys down repeatedly. Call us and we will switch demo mode off for you.

! Why to stop there
  • Wrong key sequences can change other settings.
  • Demo mode on a new install is a common surprise.
  • Your cooktop is not damaged by it.
  • We can turn it off and check the cooktop in one visit, with a written price.
Opening a panel yourself does not automatically cancel a manufacturer warranty, but it can cause accidental damage, and some manufacturers set their own service conditions. Check your warranty terms, or ask us, before deciding.

d Ed E questions
Why does my new cooktop not heat?

If d E shows, demo mode is on. It lets the display and keys respond while the elements stay cold, which is common with a new installation.

Is d E an error?

No. It is a setting, and nothing is broken. Turning demo mode off restores normal cooking, and we can do that on a short visit.

Can you switch it off?

Yes. We confirm the setting, turn it off, and test the elements. If other work is needed, we quote it in writing with a 30-day warranty.
