hello,
that is strang, both ovens with the same problem?
of course it could be the thermostat for both ovens, but it is not likely.
The first link shows you all the parts of the lower oven.
It has 2 elements. If one has gone and that one is not replaced, then nothing will change

The upper oven also has 2 elements.
Often the base element is gone first.
When you husband did not notice that, and both the base elements are gone, then indeed nothing will change
