how to fix oven light cover on hnb131551b/02?

unfortunately if the glass has split leaving the threaded part only in the housing the removal tool is no use. What I would try is to tap the glass around with a screwdriver whilst wearing protective goggles but for health and safety reasons I cant recommend that you do it as pieces of glass will fly off. Other option is to replace the complete light fitting Cheers
