i followed the tests for the micro/hood on appliancerepair.com. did the cancel/door open/unplug/plug in / uncancel/ close door . it said 8 on the display. tried all the buttons. the auto reheat displayed Hm 460. all other buttons pushed displayed 8 . but now all is working properly (?!?!) . did i reset something by doing those tests ? electrons !?!?
