You’ve pressed the timer button by accident (I just done the same thing)
All you have to do is wait a couple of minutes then hold the clock button for a few seconds and it will disappear
Hope this helps

That worked…kinda…now i have no display at all, it turns on briefly if i cycle through the timer/auto on/clock feature etc or the not yet at temperature thermometer icon comes on but i want the clock on as default… any ideas ? Thank you

So had the issue with my oven this morning, for my type I needed to change c 5 0 to c 5 2 .

Press and hold the clock for about 4 seconds to get in the the c code area - press the clock to move between c codes and use the + / - to move between 0,1,2,3
