Remove microwave outer cover. Turn on side & locate the upper & lower door switches. Better to replace in pairs even if one is ok. Remove the wire harness to each switch. Then replace switch and re connect the wire harness. Re attach outer cover and test to see if that solved the problem. If so then well done!!

Fixed.
