I've got this 2 year old oven, only tried once before today to self clean. The first time, it would start fine, then abort within 1/2 hour. Sometimes sooner. I took out the racks and then it seemed to work fine.

(Oh, I just remembered, before that time, I had it running and my kid turned it off, thinking something was wrong, I have unplugged it for a bit as well trying to reset if required).

Today, I'm having the same issue, it won't go through the 3 hour cycle, only aoubt 1/2 hour. It does turn on, get hot, I can smell it.

Does this oven know when its really dirty or is it supposed to run the entire cycle I choose? (new dishwashers can tell how dirty they are).

To answer your question, no the range doesn't know how dirty it is. Chances are the self clean mode has malfunctioned, which is part of the control board.
I myself never use te self clean on the oven as virtually all the ranges with self clean seem to have issues.
