What DEMO ON means

DEMO ON on an Electrolux built-in microwave oven in the 24, 27 or 30 inch trim sizes, or an over-the-range microwave such as the EI24MO45IB, EW27MO55HS or EW30SO60QS, means the microwave is in demonstration mode. In this mode the display and keys work, but there is no microwave power, so food stays cold. It is the same mode a store floor uses to show the controls. Many owners first think the microwave has stopped heating.

Common causes of DEMO ON

Demo mode turned on from the panel
Mode switched on during setup or after a power interruption
Control that keeps entering demo mode

✓ One safe check you can try

1. Cancel demo mode as the owner guide describes by setting the clock, then pressing 0 and STOP/CLEAR. 2. If that does not work, unplug the microwave for a moment and plug it back in. 3. Set the clock, then heat a cup of water for one minute to test. 4. If DEMO ON returns, call us.

! Why to stop there

Demo mode is a setting, so the open question is how it got switched on, and we check the panel for that.
We test the heating after the mode is off to be sure the microwave has full power.
We give a written price before work, and we tell you when nothing is needed.

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.

DEMO ONDEMO ON questions

Why does my microwave run but not heat?

In demo mode the controls and display work, but there is no microwave power. The DEMO ON message is the sign. Turning demo mode off restores heating.

How do I turn it off?

Set the clock, press 0, then STOP/CLEAR, or unplug the microwave. The owner guide describes these steps. If the message returns, the control may need a check.

Is DEMO ON a sign of a failure?

No. It is a mode, not a failure. If heating stays missing after demo mode is off, that is a separate problem we can look at.
