How long should a Kenmore gas stove last?
A Kenmore gas range like model 79070502013 typically lasts 15 years with normal household use. Keeping burners lighting properly, maintaining steady oven ignition, and cleaning grease and spills regularly helps you reach that lifespan.
Most gas ranges reach their full service life when heat, ignition, and gas flow stay consistent.
- Heavy daily cooking shortens lifespan faster than occasional use
- Frequent self-clean cycles (if equipped) add heat stress to wiring and controls
- Poor ventilation and grease buildup can damage finishes and switches
- Repeated ignition problems can overwork igniters and spark components
- Improper installation clearances can increase heat exposure to surrounding parts
Use these habits to reduce wear on common failure points like igniters, sensors, and control components.
- Keep burner caps seated correctly and ports clear of food debris
- Wipe up boilovers quickly to prevent clogged burner heads and sticky valves
- Confirm each surface burner lights within a few seconds after purging air from the gas line
- Watch for slow oven ignition (30 to 60 seconds is normal; much longer points to an ignition issue)
- Follow the setup and clearance guidance in the 79070502013 installation guide
These issues do not always mean the range is done, but they are the most common repair triggers.
| Symptom | What it often points to | Example part for this model |
|---|---|---|
| Oven will not ignite or takes too long to light | Weak oven igniter | Range oven burner igniter 5304509706 |
| Oven temperature swings or bakes unevenly | Temperature sensing problem | Range oven temperature sensor 316233903 |
| Surface burners click but do not light consistently | Igniter switch/harness or spark system issue | Range igniter switch and harness assembly 316580611 |
A 15-year lifespan assumes safe, stable ignition and proper combustion. When ignition gets unreliable, cooking performance drops and other components (like the gas valve and controls) can be stressed by repeated retries.

How to change Kenmore spark electrode igniter?
On the Kenmore gas range model 79070502013, you replace a spark electrode by removing the burner parts, swapping the electrode and its wire connection, then reassembling and verifying the burner lights within a few seconds in the LITE position. Use the 79070502013 installation guide for the correct burner-cap seating and ignition check.
- Turn all burner knobs to OFF.
- Shut off the gas supply to the range.
- Unplug the range (spark ignition uses electricity).
- Let the cooktop cool completely.
- Work in good light so you do not cross-thread screws or pinch wires.
- Remove the burner grate.
- Lift off the burner cap and burner head.
- Remove the mounting screw holding the electrode to the orifice holder (a small screw is commonly used; see range screw 316240600 if yours is stripped or missing).
- Pull the electrode up and disconnect the wire connector.
- Connect the wire to the new electrode; push the connector on fully so it seats tight.
- Reinstall the electrode into the orifice holder and secure it with the screw.
- Reinstall the burner head and burner cap.
Correct burner-cap placement matters on this model.
- Center the cap on the burner head until it sits flat.
- You should feel or hear the cap “click” into place when seated.
- The cap should not slide off-center when nudged side to side.
After restoring power and gas:
- Turn one surface knob to LITE.
- You should hear rapid sparking.
- The burner should ignite once gas is available; after air is purged, ignition is typically within about 4 seconds.
| Symptom | Most common cause | What to check |
|---|---|---|
| Sparks but no flame | Cap/head not seated, gas off | Re-seat cap/head; confirm gas supply |
| No sparks on one burner | Loose wire, bad electrode | Recheck connector; inspect electrode tip |
| No sparks on all burners | Power issue, failed spark module | Confirm outlet power; inspect wiring |
A properly mounted electrode and correctly seated burner cap help the igniter spark reach the gas stream, so the burner lights quickly and the knob can be turned out of LITE without repeated clicking.

How to use warm and hold?
On the Kenmore 79070502013 gas range, Warm and Hold (keep warm) is used to keep cooked food warm after baking. On many settings, it turns on automatically when a timed bake finishes; pressing Stop/Cancel ends Warm and Hold and stops oven operations. See the exact key sequence in the 79070502013 owner's manual.
- Cook your food using Bake (or Timed Bake, if your model supports it).
- When the timed bake ends, keep warm typically starts automatically.
- If you want to start it manually, use the Warm and Hold/Keep Warm pad (wording varies by control overlay).
- Set the hold time or temperature if prompted.
- Press Start to begin.
- Press Stop/Cancel to turn Warm and Hold off.
- Make sure the oven is not in a power failure condition; reset controls to OFF after an outage.
- Confirm the oven control is accepting key presses (a worn overlay can cause missed inputs).
- Verify the oven is heating normally in Bake; a weak igniter can prevent proper oven operation.
| Symptom | Most likely cause | What we recommend |
|---|---|---|
| Warm and Hold will not start | Control not set correctly | Follow the steps in the 79070502013 owner's manual |
| Oven will not heat, so keep warm cannot work | Ignition problem | Inspect/replace the range oven burner igniter 5304509706 |
| Buttons respond inconsistently | Worn keypad/overlay | Check the control overlay condition and connections |
Warm and Hold is designed to maintain serving temperature without continuing to cook aggressively. Using the correct setting helps prevent overcooking, drying out food, and unnecessary burner cycling.

Why is my Kenmore 79070502013 oven not heating?
If your Kenmore 79070502013 gas range oven is not heating, the most common causes are a weak oven burner igniter, a problem in the gas valve circuit, or an airflow/venting issue that prevents proper burner combustion. Use the ignition timing checks in the 79070502013 installation guide to pinpoint where the heat cycle stops.
- Confirm the range has electrical power; this oven uses an electric igniter to light the burner.
- Set Bake to 300°F and watch for ignition; normal ignition is typically within 60 seconds.
- Look for the igniter glow; it should glow before the burner lights.
- Make sure the oven vent and the area around the base/lower front panel are not blocked.
- If there was a power outage, reset all oven controls to OFF, then try again.
| What you see | What it usually points to | What to do next |
|---|---|---|
| No igniter glow at all | Power, wiring, control, or switch/harness issue | Check connections; inspect harness; test safely with a meter |
| Igniter glows but burner never lights | Weak igniter or gas valve not opening | Replace the igniter first in most cases |
| Burner lights after a long delay, then cycles oddly | Weak igniter or marginal gas valve operation | Time ignition; replace igniter if slow |
| Burner lights but goes out quickly | Normal cycling can occur after preheat | Verify temperature stability; check sensor if temps are off |
For model 79070502013, these parts are frequent solutions when the oven will not ignite or heat correctly:
- Range oven burner igniter 5304509706 (most common for “glows but won’t light”)
- Range oven gas valve (if the igniter is proven strong but the valve will not open)
- Range oven temperature sensor 316233903 (more common for incorrect temperature than no heat)
This Kenmore gas range relies on an electric igniter to heat up enough to open the oven gas valve and light the burner. If the igniter is weak, the valve may never open, so the oven stays cold even though the control is set to Bake.
