Kenmore microwave model number illegible

[paulw]

My over-the-range Kenmore microwave's light and fan don't turn off when the door is shut, all of a sudden.  I'm going to need to take it apart to see if I can find anything broken, but getting parts might be a challenge: the thing on the inside front that lists the model number is sort of smudged/rubbed off across the middle, so some of the model number isn't legible.  Is there any other way to figure out what model number this thing has?

And now, after a few days of being a slacker, as I started to get to work and take it off so I could look behind it for a model number, it's suddenly working again!
