Replacing the lamp in the microwave of a...

Question

I am trying to find out how to replace the lamp in the microwave on this built in oven/microwave. Nothing in the users manual mentions the bulb in the microwave. (They mention the bulb in the oven and that's a breeze) I checked the Kitchenaid site and found the parts manual and see that it's a halogen bulb and it's in the $30 range. Just need to know how to replace it. Any ideas?
