@Buzzbea,
That number is connecting up on the search for an online copy of the oven's manual. It still might well be the oven's model number, but let's do a quick check.
Here is a pic of where the tag with the model number is likely to be located:
And here is a pic of what should be on the model plate. Often times, model plates also have serial numbers, lot numbers, etc. So be careful it is the model number. I frequently find it useful to use a magnifying glass on things like this, like I just did on my old lawnmower.
Does that help? There are still some things we can do if it doesn't help, but it's worth checking this first.
