665.5029100 Kenmore stove constant buzzing/humming

[NickG]

Wouldn't you know it?  After some recent purchases, our oven is the only appliance in the kitchen that is not stainless steel.  Naturally, my wife is dreaming of getting rid of this perfectly working appliance because it doesn't match.

Not a week after we got our new Dishwasher and refrigerator, the oven begins to emit an annoying buzzing sound 24/7.

What did my wife do to this oven?

Is it high pitched, low pitched? Does it sound like it's coming from the back of range?
