This 500 Series double oven belongs to an earlier generation. It is controlled by turning knobs and flipping switches, not by a touch display, so you will never see an E0xx code on it, however badly something has gone wrong.
Owners who have kept one for years describe the same story: knobs that feel loose or stick, a set temperature that no longer matches what the oven actually does, and a door that has lost some of its seal and hinge firmness after many self-clean cycles. All of that comes from age and heat, not from a design flaw.
Since there is no display to read, we diagnose it the old-fashioned way. We test the thermostat, the switches and the heating elements one at a time with a meter and see which one has drifted out of range.
We test the thermostat, switches and elements directly instead of reading a code. Our technicians are equipped to do that kind of testing on knob-controlled ovens like this one.
A little harder than for current digital models. Heating parts and switches are still commonly serviced, though, so a repair is often still practical, and you see a written price first.
Only the upper one, which uses a European Third Element. The lower cavity is a standard thermal oven without convection, so it bakes with plain radiant heat only.
