A typical residential oven or range lasts 13 to 18 years, per Consumer Reports reliability data. Gas ranges average the longer end of that range because their ignition components (spark modules, gas valves) fail less frequently than electric heating elements.
Premium brands are a different category. Wolf, Viking, Thermador, Miele, and Monogram are engineered for 20-plus years of service, and the repair ecosystem for those brands supports it — OEM parts stay available, and the sealed-burner and convection systems are serviceable rather than disposable. A 15-year-old Wolf range with a $400 igniter-assembly repair is almost always worth the fix. A 15-year-old basic electric range with a $400 control-board failure often isn't.
Induction cooktops are newer to the mainstream U.S. market, but early reliability data suggests lifespans similar to smooth-top electric (12 to 15 years) with lower failure rates on the cooking surface itself and higher failure rates on the inverter electronics.
The most common late-life failures on ranges are: bake elements and broil elements (electric), igniters and spark modules (gas), oven temperature sensors (both), and door hinges and door seals (both). All are routine repairs. The repairs that argue for replacement are control-board failures on units past the 12-year mark, where the replacement board cost approaches half of a new mid-tier range's purchase price.
