This is a high-end dual-fuel professional range typically purchased for premium performance, strong baking control, and long-term kitchen investment. Repairs are often worth doing because replacement involves major cost plus potential cabinetry and ventilation changes.
Common service items include igniters, sensors, and electronics; these can be justified even when expensive if the range is otherwise in excellent condition. Replacement becomes more likely when multiple control systems fail or when structural issues emerge (significant corrosion, oven cavity damage, repeated gas-safety shutdowns).
Also consider parts availability: older pro ranges can have longer lead times, which matters if this is the household's primary cooking appliance. If the range is a centerpiece of the kitchen and the failure is isolated, repair often preserves value better than replacement.
