Two Systems Built to Work Independently
Most ILVE stoves run dual fuel — gas burners up top, an electric fan forced oven underneath. Unlike some combined stoves where the cooktop and oven share a control board or ignition circuit, ILVE's dual fuel design keeps the two largely separate. That's good news in one sense: a fault in the burners is unlikely to be connected to a fault in the oven, so the two rarely need to be diagnosed as one problem.
It also means the two halves genuinely need different expertise. The cooktop is a gas appliance, with its own burners, jets, ignition and regulator to understand. The oven is an electric appliance, with its own element, thermostat and control logic. A technician who's confident with one and unsure of the other ends up guessing on whichever half they know less well, or calling in someone else to finish the job.
The build itself also asks for a heavier hand. Cast iron trivets, brass burner heads and thick steel doors are part of why ILVE stoves have such a following among serious home cooks, and part of why parts and adjustments on them don't behave quite like a lighter, mass market stove.
