Frigidaire Microwave Error Code DEMO

DEMO indicates the microwave is in Demonstration Mode, a setting designed for retail store displays. In this mode the controls and display function normally and the timer counts down rapidly, but the magnetron is completely inactive and no heat or microwave energy is produced. This is not a fault code and does not indicate any damage or malfunction. It can be cleared with a specific button sequence or by cycling power.

The microwave will not heat food while DEMO is active because the magnetron is completely disabled in this mode. There is no safety hazard associated with the DEMO mode itself, but you cannot use the appliance for cooking until the mode is cleared. Do not place food inside expecting it to cook, as nothing will be heated regardless of how the display appears to count down.

There is no repair cost associated with the DEMO code because it is a software mode, not a hardware failure. No parts need to be replaced and no technician visit is required. The fix involves a button sequence or a power cycle, both of which can be performed by the owner at no cost. If the DEMO mode cannot be cleared after multiple attempts, a service call to inspect the control board could range from $75 to $150 depending on your location and service provider.

Press the Timer/Clock pad, then the number 0 pad, and then the Clear/Off pad in sequence. If the display does not return to normal after this sequence, unplug the microwave from the wall outlet, wait about 30 seconds, and plug it back in. After restoring power, test the unit by attempting to heat a cup of water to confirm the magnetron is now active.

Unplugging the microwave and replugging it can clear the DEMO mode on some Frigidaire models because it resets the control board. However, on models that store the Demo Mode setting in non-volatile memory, a power cycle alone may not be sufficient. If the DEMO indicator returns after replugging, use the button sequence: Timer/Clock, then 0, then Clear/Off to exit the mode properly.
