customer changed m/o light bulb with a cheaper bulb..
when he tried it nothing happend so he tried to screw bulb in a bit further cooker then made a bang.. now main oven and clock wont come on..
top still works ok.. had a quick look clock looks ok….cant really seen anything where a bang would come from …
any ideas..
customer said there is lots of complaints about this on google..ie light bulb change then bang
