Interior light replacement - where is/how to get to bulb

Microwave Repair
1

I’m trying to find where the interior halogen light bulb is on a GE Spacemaker xl1800 model jvm1870sk04, self venting microwave is, above stove model, and how to get to the bulb, and which bulb it is that I need to replace with it.
The manual does not describe where it is on this specific model, or what bulb to replace it with.
I’m stumped.

help please.
Thanks.

Here is the manual, take a look at page 36.
If this does not work then you will probably have to unmount the unit and remove the outer cover to get at the bulb.
