I can't find the model number, but on the front it says "super Capacity 465" and "accubake system". While we were moving the range the door came off, it is now back on, but the light won't turn off. Is this problem connected to the door coming off? Do we need to call a repair man to fix it, or can we do it ourselves? Is it safe to cook in teh oven or could there be a short in it somewhere?
