How long should a Kenmore gas stove last?
A Kenmore gas range like model 79073232313 typically lasts 15 years with normal household use and basic maintenance. Keeping burners clean, ensuring proper ignition, and addressing heating issues early helps you get the full service life from the oven and cooktop.
What affects lifespan the most
- Cleaning and spill control: baked-on spills and grease can clog burner ports and stress components.
- Ignition health: weak ignition can cause delayed lighting and extra wear.
- Heat accuracy: an oven that runs hot or cold makes parts work harder.
- Ventilation and grease management: reduces buildup around controls and surfaces.
- Prompt repairs: replacing a failing part early prevents secondary damage.
Quick maintenance checklist (monthly or as needed)
- Wipe cooktop and burner areas after spills; keep burner ports clear.
- Confirm the oven lights normally; in many gas ovens the igniter should glow and the burner should light within about a minute.
- Use the correct bulb type and wattage for the oven light; replace if it flickers or fails.
- Check that knobs turn smoothly and flames look steady (not lifting, yellow, or noisy).
- Review cleaning steps and safe operating practices in the 79073232313 use and care guide.
Common “wear” parts that can shorten performance
If the oven struggles to light or takes a long time to heat, these parts are often involved:
| Symptom | Common cause | Example part for this model |
|---|---|---|
| Oven won’t ignite or ignites slowly | Weak oven igniter | Range oven igniter 5304509706 |
| Oven temperature seems off | Sensor drifting out of range | Range oven temperature sensor 316233903 |
| Oven light out | Burned-out bulb or socket issue | Appliance light bulb, 40-watt 316538904 |
Why it matters
A gas range can keep running for years even with minor issues, but delayed ignition, inaccurate temperatures, and poor airflow increase stress on the igniter, gas valve system, and controls. Routine cleaning plus timely part replacement helps your 79073232313 cook more consistently and last its full expected life.

How to change Kenmore spark electrode igniter?
On Kenmore gas range model 79073232313, changing a surface-burner spark electrode means removing the grate and burner pieces, unfastening the electrode from the orifice holder, moving the wire to the new electrode, then reassembling and testing ignition. Use the 79073232313 installation guide for burner-cap placement and ignition verification.
Safety and prep
- Turn all surface burner knobs to OFF.
- Shut off the gas supply at the range shutoff valve.
- Unplug the range (spark ignition uses electricity).
- Let the cooktop cool completely.
- Remove the grate, then lift off the burner cap and burner head.
Replace the electrode (typical steps)
- Remove the mounting screw holding the electrode to the orifice holder.
- Lift the electrode enough to access the wire connector.
- Transfer the wire to the new electrode (push-on terminal fully seated or crimped securely).
- Reinstall the electrode into the holder and tighten the screw.
- Reinstall the burner head and cap; keep the cap centered.
Test ignition after reassembly
The installer procedure for this model describes what “normal” looks like.
| Check | What you should see | What to fix if not |
|---|---|---|
| Spark in LITE | Clicking/sparking sound | Restore power; check connection |
| Ignition time | Lights within about 4 seconds after air is purged | Re-seat cap/head; confirm gas is on |
| After lighting | Turn knob out of LITE | Leaving in LITE keeps sparking |
If it still will not spark
These parts commonly cause “no spark” across one or more burners:
- Range igniter switch and harness assembly 316580611 (switches that trigger spark when you turn a knob)
- Range spark module 808608802 (creates spark for the surface burners)
Why it matters
Correct electrode mounting and burner-cap alignment help the burner light quickly and evenly, reducing delayed ignition and nuisance clicking.

What does F31 mean on a Kenmore gas stove?
On Kenmore gas range model 79073232313, the F31 error points to an oven temperature sensing problem (the control is seeing an out-of-range temperature signal). Clearing the code may get you cooking again briefly, but the fix is usually checking the sensor circuit and replacing the sensor if it tests bad; see the 79073232313 owner's manual for the exact reset steps and error behavior.
What to do first (safe, quick checks)
- Press Clear/Off to clear the code.
- Turn power off at the breaker for 5 minutes, then restore power and set the clock.
- Try Bake again; if F31 returns, stop using the oven until the cause is corrected.
- If you smell gas or suspect a gas leak, shut off the gas supply and have the range checked by a qualified technician.
Most common causes of F31
| Likely cause | What you may notice | Typical fix |
|---|---|---|
| Failed oven temperature sensor | Oven won’t heat correctly; code returns quickly | Replace the sensor: range oven temperature sensor 316233903 |
| Loose or damaged sensor wiring/connector | Code appears intermittently, especially after moving the range | Reseat connector; repair damaged wires |
| Control board input issue | Sensor tests good but code persists | Diagnose wiring first; control board may need service |
How we recommend diagnosing it
- Inspect the sensor harness at the sensor and at the control for loose pins or heat damage.
- Test the sensor resistance with a multimeter (room-temp readings are typically around 1,000 to 1,100 ohms for many ranges).
- If wiring is good and readings are out of range, replace the sensor.
- If the sensor tests in range and wiring is solid, the issue is usually in the control circuit.
Why it matters
The oven control uses the temperature sensor signal to regulate heat. When that signal is wrong, the range can overheat, underheat, or shut down for safety, which is why the control triggers an F code.
