You should be able to access it by removing the grill. Then remove the bulb holder. Don't touch the bulb with bare fingers. If you do touch it, clean it with rubbing alcohol before turning it on.
FOUND IT! Yes, removed the grill, and right in the middle area, near the front, is a metal "box like" bulb holder. One screw allows that to come up.
This model has convection heat....there is no glass lens or any removable panels on the inside. The bulb is above an area which has a "grill" of holes in the stainless.
