Questions people ask about DEMO ON

What does DEMO ON mean on a Dacor microwave?
DEMO ON means your Dacor microwave is operating in Demonstration Mode. In this state, the magnetron is disabled so no microwave energy is produced, but the display and controls work normally and the timer counts down rapidly to simulate a cooking cycle. This is not a fault code and does not indicate any damaged or failed components.
Is it safe to use my Dacor microwave while DEMO ON is displayed?
The microwave is safe to operate while in Demo Mode, but it will not heat any food or liquids because the magnetron is completely inactive. Running the unit in Demo Mode presents no electrical or radiation hazard. Simply cancel the mode using the CLOCK, 0, STOP/CLEAR sequence before attempting to cook.
How much will it cost to fix the DEMO ON issue on my Dacor microwave?
There is no repair cost associated with DEMO ON because it is not a hardware failure. The condition is resolved entirely through a button sequence on the control panel at no cost. If after following the cancellation steps the mode cannot be cleared, a service technician visit could range from $75 to $150 for diagnosis, though this scenario is very uncommon.
How do I turn off Demo Mode on my Dacor microwave?
To cancel Demonstration Mode, press CLOCK, then press 0, then press STOP/CLEAR. This three-button sequence is the only way to exit the mode. After completing these steps, the microwave returns to normal operation with full heating capability restored.
Will unplugging or resetting my Dacor microwave clear the DEMO ON display?
No, unplugging the microwave or cutting power to it will not clear Demonstration Mode. The setting is stored in the control board and persists through power interruptions. You must use the specific button sequence of CLOCK, then 0, then STOP/CLEAR to exit the mode.
