How long should a Kenmore gas stove last?
A Kenmore gas range like model 79072903013 typically lasts 15 years with normal household use. Keeping burners clean, confirming proper ignition, and addressing weak flames early helps reduce wear on ignition parts, gas valves, and oven components.
Typical lifespan and what affects it
Most gas ranges reach their full service life when heat and ignition systems stay clean and properly adjusted.
- Heavy daily cooking shortens lifespan faster than occasional use
- Spills and boilovers can clog burner ports and corrode igniters
- Poor ventilation can leave grease residue on controls and surfaces
- Power surges can stress electronic ignition and control components
- Delayed repairs (igniter, sensor, gas valve) often lead to bigger failures
Maintenance that helps you reach 15 years
Use the care and cleaning steps in the 79072903013 owner's manual and keep these habits consistent:
- Clean surface burner caps and ports so flames stay even and blue
- Wipe up acidic spills quickly to prevent corrosion
- Keep the oven bottom area free of heavy grease buildup
- Replace a dim oven light promptly (it is a wear item)
- Verify burners ignite promptly after cleaning or moving the range
Quick ignition check (surface burners)
The installation instructions note that each surface burner should light within about 4 seconds after air is purged from the gas line. Use the 79072903013 installation guide for the exact procedure.
| What you notice | What it usually means | What to do next |
|---|---|---|
| Clicking but no flame for several seconds | Air in line, dirty burner, weak spark | Clean burner parts; retry ignition check |
| Flame is uneven or lifting | Clogged ports or mis-seated cap | Re-seat cap; clean ports |
| Oven takes long to heat or won’t ignite | Weak igniter or gas flow issue | Check igniter and gas valve operation |
Parts that commonly wear out first
These are common wear-related repairs on gas ranges:
- Tappan range oven burner igniter 316489403 (bake ignition problems)
- Frigidaire range oven temperature sensor 316490000 (temperature accuracy issues)
- Appliance light bulb, 40-watt 316538904 (oven light not working)
Why it matters
A gas range can often run well past a decade, but ignition and temperature control problems can cause slow preheat, uneven baking, or burners that will not light. Routine cleaning and fast part replacement protect performance and help you get the full expected lifespan.

What does F31 mean on a Kenmore gas stove?
On Kenmore gas range model 79072903013, the F31 code is an oven control fault tied to the oven temperature sensing circuit; it shows up when the control is not getting a normal temperature signal. Use the troubleshooting steps in the 79072903013 owner's manual to match the code behavior to your symptoms.
What to do first (quick checks)
- Press Clear/Off to stop the beeping.
- Reset power: turn the range breaker off for 1 minute, then turn it back on.
- Start Bake and watch when F31 returns (immediately, during preheat, or after the oven is hot).
- If the oven was recently installed or moved, confirm the basics in the 79072903013 installation guide (proper grounding and correct hookup help prevent control faults).
Most common causes on gas ranges
F31 is usually triggered by a problem in one of these areas:
- Oven temperature sensor out of range
- Loose or heat-damaged sensor wiring or connector
- Control board connection issue
- Wire harness damage from pinching or rubbing
| Symptom | What it points to | What we do next |
|---|---|---|
| F31 appears as soon as Bake starts | Sensor circuit or connector issue | Inspect and reseat connections, check wiring |
| Oven heats erratically before the code | Sensor drifting or intermittent wiring | Inspect harness, replace sensor if needed |
| Code comes and goes when the oven is bumped or door is moved | Loose plug or damaged harness | Secure connector, repair wiring |
Parts that commonly resolve F31-type faults
If inspection shows the sensor is the issue, a common replacement for this model is the range oven temperature sensor 316490000.
Why it matters
When the control cannot trust the temperature signal, it can shut the oven down or regulate heat incorrectly; that leads to poor baking results and repeated alarms until the circuit reads normally.

What model is my Kenmore gas range?
Your Kenmore gas range model number is printed on the identification plate. On Kenmore model 79072903013, that plate is on the right-hand surface of the oven front frame; you can see it by opening the storage drawer, warmer drawer, or broiler drawer (depending on your configuration). See the 79072903013 installation guide for the exact plate location.
Where to look (fast checklist)
- Pull out and open the bottom drawer (storage, warmer, or broiler drawer)
- Look at the right-hand front frame of the oven opening
- Find the identification plate (model and serial label)
- Write down the model number and serial number exactly as shown
- Also note any lot number or letter listed on the plate
What the identification plate tells you
Besides the model number, the plate typically includes key specs used for parts and service.
| Label item | What it’s used for |
|---|---|
| Model number | Matching the correct Kenmore parts diagrams and parts |
| Serial number | Verifying production run details for service |
| Lot number/letter | Helps narrow down version changes within a model |
| Fuel and pressure info | Confirms how the range was set up when it left the factory |
Why it matters
Kenmore ranges often have similar-looking designs across multiple model series (for example, 790.7250, 790.7280, 790.7290 families). Using the exact model number from the identification plate prevents ordering the wrong igniter, temperature sensor, burner parts, or hardware.
