Product review (1 stars): Not a quality product
I have a similar model to this one.  It never kept accurate temperature and has now given up after we ran the self-cleaning cycle.  My husband called the service line and they told him they had heard of their ovens dying after self-cleaning before.  They don't want to say this is a known problem but that is what it is.  If you do buy this oven definitely never run the self-cleaning cycle.  Its bad news.
