Hello Sheldon;
My name is Peter. I am a retired field service appliance technician.
You did not provide a model number, which should be on the face of your microwave after you open the door.
So, you are going to have to help yourself.
Go into the following website. Put in your model number. You will get diagrams, part numbers and cost.
You can get the light from your local Lowe's or Home depot.
