What DEMO ON Means
DEMO ON means demonstration mode: features can be shown with no microwave power. The manual also warns that a cooking time counting down very rapidly is a sign of demo mode. It is set with Set Clock, 0 and START held for three seconds, and canceled with Set Clock, 0, STOP/CLEAR, or by unplugging and replugging.
Common Causes of DEMO ON
- Demo mode switched on
🔧 One Safe Check You Can Try
Press Set Clock, 0, then STOP/CLEAR. If that is awkward, unplug the microwave and plug it back in.
⚠ Why You Shouldn't Go Further Than That
- No repair is needed.
- If food still does not heat after leaving demo mode, the microwave needs service.
Opening a panel to inspect or repair something yourself doesn't automatically cancel your manufacturer's warranty — but it can risk accidental damage, and some manufacturers do have specific service conditions. Check your product's warranty terms, or ask us, before deciding.
