The quiet advantage of the NEM5666UC is that age takes it one zone at a time. Bosch built it as a radiant electric cooktop for a 36 inch opening, with 37 inch black ceramic glass, and has since discontinued it.
Wide radiant tops have lots of separate elements and switches, so when one gives out the cooktop keeps working: a 36 inch radiant with a single dead zone still has four others. That lets you book the repair calmly, which you cannot say about a refrigerator that has stopped cooling.
Over the years, the infinite switches wear and no longer hold a setting, and the glass shows wear across the large cooking area. On a visit we test each element and switch in turn, so we can tell you which are tired, and we give the price in writing before ordering parts.
Yes, the other zones keep working, so the repair can be scheduled. Avoid using the dead one, and let us test the element and switch to find the part.
The infinite switch, which sets the zone's power, can wear until it stops holding a setting. We can test it and, if needed, replace it.
Usually not. A repair is normally more sensible than a new cooktop when the rest is working. We tell you honestly if the combined repairs start to approach replacement.
