How long do ranges last? Longer than most kitchen appliances: InterNACHI's chart lists a gas range at 15 to 17 years and an electric range at 13 to 15. Fuel type matters less to how a range ages than the condition of its heat source, its door seal and its controls.
Typical lifespan
InterNACHI gives these figures, with regular maintenance and normal wear:
- •Gas range: 15 to 17 years
- •Electric range: 13 to 15 years
- •Gas oven: 10 to 18 years
The gas oven figure is a separate row, and its range overlaps both range figures. InterNACHI doesn't explain the difference, and the chart calls all its figures guidelines only. The long life comes partly from simplicity: an oven cavity, a door and a heat source have fewer moving parts than a washer or a refrigerator.
What wears out first
| Part | Typical sign of wear |
|---|---|
| Oven igniter (gas) | Slow preheat, a delay before the burner lights, or no bake heat |
| Bake and broil elements (electric) | Visible blistering or a break, a section that doesn't glow, no heat |
| Oven door gasket | Heat escaping at the top of the door, uneven baking, a frayed or flattened seal |
| Temperature sensor | An oven that runs hot or cold compared with a thermometer |
| Surface burners or elements | A burner that lights slowly, a coil or radiant element that heats unevenly |
| Door hinges and springs | A door that won't stay closed, drops open or doesn't seal evenly |
| Knobs, switches and touch controls | Knobs that slip, keys that don't respond, a display with dead segments |
What shortens its life
- •Grease and spills left to bake on, especially around igniters and burner ports. KitchenAid notes that grease or debris buildup, or the age of the appliance, can affect a gas oven's ability to ignite.
- •Slamming the oven door or leaning on it, which strains the hinges and the gasket.
- •Cleaners the manual doesn't approve, especially on the door gasket and cooktop.
- •Using the oven or a gas burner to heat the room.
- •Heavy pans dropped or slid on a glass cooktop; see glass cooktop lifespan.
What helps it last
- •Wipe up spills once the range is cool, before they bake on.
- •Follow the manual's cleaning instructions, including what not to clean. See oven door gasket wear.
- •Close the door gently and don't rest heavy items on it.
- •Keep burner caps and heads seated and dry after cleaning; see gas burner wear.
- •Check your oven against a thermometer now and then, so drift doesn't go unnoticed.
Signs of age vs. signs of a fixable fault
An aging range shows wear across the whole appliance: worn knob markings, enamel chips, hinges that have loosened, a door that no longer seals as tightly, and controls that need a firmer press.
When one part fails, the change is usually sudden and limited to one function. The oven won't heat while the cooktop works. One burner won't light. The broil works but bake doesn't. Each points to one component, such as an igniter, an element or a sensor. Our post on gas oven igniter lifespan covers the most common one on gas models. If you ever smell gas, leave the house and call 911 or your gas utility from outside. For other problems, our range service covers gas and electric models.

Takeaway: Ranges are among the longest-lived appliances on InterNACHI's chart, and clean igniters, seals and burners help them get there.
When an oven or range loses one function, a single part is usually behind it; call True Fix Chicago at (312) 896-8111 to have it tested.
