How long do ovens last?
The typical range
Ovens and ranges commonly remain in service for roughly 13 to 15 years, and it is not unusual to find one working well past twenty. They are the longest-lived major kitchen appliance, and the reason is mechanical simplicity: an oven is an insulated box, a heat source and a thermostat. There is no pump, no drum, no compressor, and very little that runs.
The published figures separate gas from electric, and gas comes out ahead.
| Source | Published figure | What it is based on |
|---|---|---|
| InterNACHI | 15–17 gas, 13–15 electric | Home-inspection reference; gas and electric listed separately |
| NAHB | 15 years (gas) | Survey conducted in 2006; gas ranges among the longest-lived appliances surveyed |
| This site | 13–15 years | A single band across both types, being the range in which most units are still in service |
Why gas tends to last longer
A gas burner is a valve, a tube and an igniter. An electric element is a resistance heater that expands and contracts every time it cycles, and eventually fails at a weak point. Thermal cycling is what wears out electric heating elements, and gas burners simply do not have that component.
The trade is that gas has an igniter, which is a genuine wear item and the single most common gas oven fault. A weak igniter that no longer draws enough current to open the gas valve produces the classic symptom: the oven clicks or glows but never lights, or takes a very long time to reach temperature.
Electric ranges with a glass ceramic top add a failure mode gas does not have — the top itself can crack, and on many models that is not economically repairable.
What fails, and roughly when
Almost everything on this list is a wear item worth replacing, which is why ovens stay in service so long.
| What has failed | How it shows | Usually worth repairing? |
|---|---|---|
| Bake or broil element (electric) | No heat from one element, or visible break in it | Yes — inexpensive and expected at least once |
| Igniter (gas) | Clicking or glowing but not lighting; very slow to heat | Yes — the most common gas oven fault, and a wear part |
| Temperature sensor or thermostat | Oven running hot or cold, uneven baking | Yes — cheap, and worth doing before assuming the oven is inaccurate |
| Door hinges or door seal | Door not closing square, heat escaping, long preheat | Yes — and a leaking door makes everything else look worse |
| Surface burner or receptacle | One ring not working | Yes |
| Spark module or switch (gas) | Continuous clicking, or no spark at any burner | Yes |
| Control board or clock assembly | Dead display, controls unresponsive | Depends — the one part costly enough to make an older range marginal |
| Glass ceramic cooktop cracked | Visible crack or chip in the surface | Rarely — often approaches the cost of replacing the range |
| Cabinet or cavity corroded, insulation degraded | Rust through, oven never reaching temperature | No — this is the end of it |
What shortens it
Ovens are hard to wear out, and two of the four items here are self-inflicted.
- Heavy self-clean use. The self-clean cycle runs the cavity far hotter than normal cooking, and it is hard on elements, door seals, thermostats and control boards. Occasional use is fine; running it monthly is a way of ageing the oven faster.
- Spills left to bake on. Acidic and sugary spills attack the enamel and, at the cavity floor, eventually the metal beneath it.
- Door misalignment. A door that no longer seals means longer heating, more cycling and more wear on everything that cycles.
- Cleaning products on the wrong surfaces. Abrasives on a glass top and oven cleaner on a self-clean cavity liner both cause damage that is not repairable.
Repair or replace
Ovens lean strongly towards repair, and for longer than any other appliance in the kitchen. Elements, igniters, sensors, switches, hinges and seals are all ordinary parts, and none of them indicates the appliance is finished. A twenty-year-old oven with a failed element is worth fixing.
Three situations change that. A control board on an old range can cost enough to be a genuine decision. A cracked glass cooktop is often uneconomic. And a cavity that has corroded through, or insulation that has broken down so the oven cannot hold temperature, is the end — those are the parts you cannot sensibly replace.
For built-in wall ovens there is a further practical point: cabinet openings and electrical provision were built around a specific unit, and current models do not always drop into an old aperture. Check dimensions before committing to replacement, because the cabinetry work can cost more than the difference between repairing and replacing.
Getting more life out of one
Use the self-clean cycle sparingly and wipe spills before they bake on. Check the door closes square against its seal and have the hinges seen to if it does not. If baking has become uneven or the oven seems to run hot, have the temperature sensor checked before concluding the oven is worn out — that is a cheap part and a common cause. Keep abrasives off a glass top.

Common questions
- Is a 20-year-old oven worth repairing?
- Often, yes. Ovens have very little that wears, and the common faults — elements, igniters, temperature sensors, hinges, seals — are inexpensive standard parts. A twenty-year-old oven with a failed element is a straightforward repair. The exceptions are a costly control board, a cracked glass cooktop, or a corroded cavity.
- My oven does not hold the right temperature. Is it finished?
- Usually not. The most common causes are a failed temperature sensor or thermostat and a door that no longer seals, both of which are cheap to put right. Insulation breakdown, which genuinely does end an oven, is much rarer and normally comes with other signs of age.
- Do gas ovens last longer than electric ones?
- The published figures suggest so — InterNACHI puts gas ranges at 15 to 17 years against 13 to 15 for electric. The likely reason is that electric heating elements fail from thermal cycling and gas burners have no equivalent part. Gas has its own wear item in the igniter, but that is cheap to replace.
- Does the self-clean cycle damage the oven?
- Used occasionally, no. Used frequently, it is one of the few things that measurably shortens an oven's life: the cycle runs far hotter than cooking and stresses elements, seals, thermostats and control boards. Wiping spills as they happen is gentler on the appliance than relying on the cycle.
Where these figures come from
- InterNACHI's Standard Estimated Life Expectancy Chart for Homes
International Association of Certified Home Inspectors · retrieved 30 July 2026
Home-inspection reference giving: refrigerator 9-13 years, dishwasher 9, clothes washer 5-15, clothes dryer 13, gas range 15-17, electric range 13-15, microwave 9, freezer 10-20, conventional gas or electric water heater 6-12, tankless 10. Explicitly presented as a guideline assuming recommended maintenance and normal wear, not a warranty. nachi.org blocks automated requests, so these figures were read from a verbatim reproduction and should be re-checked in a browser at the next review.
- Study of Life Expectancy of Home Components
National Association of Home Builders (Economics Group) · retrieved 30 July 2026
Survey conducted summer 2006, published February 2007, superseding NAHB's 1993 study in Housing Economics. Gives refrigerator about 13 years, dishwasher 9, clothes dryer about 13, gas range 15, microwave 9, and water heater about 10 whether gas or electric. Now twenty years old, which is the main reason it is shown alongside the InterNACHI figures rather than treated as current: it predates the shift to electronic control boards, and it is the disagreement between the two that is informative.
