Report "Hi. On my Baumatic BTM24 Microwave, the "10 MIN", "1 MIN" and "10 SEC" buttons have suddenly stopped working, all other functions of the microwave are working properly. Is there a way to reset the microwave to enable the buttons to work again, or are there any other ways to re-activate them please? I have tried turning the microwave off (at the main power switchboard as the microwave is inbuilt and the plug is behind it) but had no effect. Regards David Cook"
