DEMONSTRATION MODE – PROGRAMMABLE CONTROLLER MODELS
For display purposes, the appliance has a demonstration mode to enable demonstration of oven functionality without consuming power. In demonstration mode, the display, the light and the fan only are operational.
When the appliance is in demonstration mode and the display is switched on, the clock symbol will be on.
If the appliance is in demonstration mode, to operate the appliance normally the demonstration mode will need to be deactivated.
To deactivate demonstration mode:
1. Ensure the oven is off by pressing the ON/OFF button. 2. Press and hold the ON/OFF button until the display turns
ON then OFF and a single ‘beep’ is heard. Immediately after press and hold the ‘Timer’ and ‘–’ buttons simultaneously, until a triple beep sounds to confirm
the operation.

Have issue on my kenmore mic oven model 721.6365330 have no power although fuse is not burnout and poweroutlet has no either problem.

This can be due to wrong choice or fault in the power supply ,main board or the magnetron.
You should try with a preset selection and if the microwave works then the fault relates to correcting the power to time settings.
Check out with microwave cooking tips.

Without a make and model number it is difficult to guess.
If the door switches are faulty, odd things will happen. I suggest they are checked first of all.

would probably help us to understand if you would please re word your question. Not too clear, sorry
