Oven turns on along without someone pressing a button

Strangely in all of this, u don't tell the oven when to start - it works it out itself!
First u need to set the length of cooking time, eg 2hrs.
Press the cooktime button(2nd one along), THEN use the +/- buttons to set the display to 2.00.
THEN press the readytime button (3rd one), and use the +/- buttons to set the end time.eg 1730hrs
The display should then revert to the present time.
THEN turn the oven control to the required temperature.
The oven will switch on at 1530 hrs.
If u were to press the cooktime button ONCE WHILST the oven was on - it will display the cooktime remaining.
AT 1730, the oven will switch off and the alarm will sound
To switch off the alarm, press the minuteminder button - first one - looks like a bell, THEN
REMEMBER to cancel the programme by pressing buttons 2 and 3 TOGETHER, otherwise it will do it again tomorrow!
HOPE THIS HELPS
I would suggest first.trying it when you're at home all the time the oven is on.

Press the on button again its a combo button.

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.

Press and hold the Broil Max Econo button for 5 seconds.
Only this button and without turning on oven.

This particular brand is well known for defective door switches.

Turn off amin power wait for a few min's then turn power back on it should come up normal , let's hope so !

HELLO.

If by not turning mean turntable fault,the solution is given below in detail.

1 Press "Stop" to halt microwave operation.

2 Press the "Turntable" button once to turn off rotation.

3 Push the door-release button to open the microwave oven if you do not have a "Turntable" button on your control keypad.

4 Lift and remove the glass platter from the oven, then pick up the plastic track with three wheels below the platter. Set aside these parts.

5 Insert the elevated microwave cooking tray into the oven. The tray has three to four short legs that hold it above the bottom of the microwave, keeping it from interfering with the rotating bolt in the bottom center of the oven the drives the turntable. You can now place food on the elevated tray and cook normally without disrupting the drive bolt.

Thanks.

My son came along and managed to get the clock operating once more by just pressing one of the buttons and turning the knob to set the time. Many thanks for your contact. It was much appreciated. I shall know what to do in case this ever happens again.

microwave quits working and F3 comes up on the readout - along with a series of beeps - pressing any of the buttons on the touchpad does nothing - The F3 stays there and beeps intermittently
