Guide :Microwave Ovens : Spacemaker JVM1640SJ Microwave Oven
Surface lights We replace the light bulbs frequently, about 12 in two years. We had the same style Microwave prior to the new one and did not have to change bulbs but once a year (approx).
The bulb socket is dropping little black pieces of a plastic material, I think the socket is deteriorating!
When the old bulbs are removed they are very black, like they are over heating.
