How long should a Kenmore gas stove last?
A Kenmore gas range like model 79078803501 typically lasts 15 years with normal household use. Regular cleaning to prevent grease buildup and addressing small issues early (like weak ignition or uneven baking) helps you reach that lifespan.
- How often you cook (daily use wears igniters, valves, and controls faster)
- Grease and spill cleanup (grease can become a fire risk and damages finishes)
- Proper ventilation during high-heat cooking and self-clean cycles
- Avoiding harsh cleaners or incorrect tools on sensitive surfaces
- Fixing small performance problems before they strain other parts
Use the cleaning and care steps in the 79078803501 owner's manual and keep these habits consistent:
- Wipe up spills promptly; remove sugary or melted plastic spills as directed
- Keep the cooktop and burner area free of grease buildup
- Use the self-clean cycle appropriately; ventilate the kitchen during the first self-clean
- Let the range warm above 32°F for at least 3 hours before powering it on after cold storage
- Replace failed wear items promptly (for example, a burned-out oven light)
| Part type | What you’ll notice when it’s failing | Typical impact |
|---|---|---|
| Ignition components | Clicking but no flame, delayed ignition | More stress on gas/ignition system |
| Oven door seal | Heat leaking, longer preheat, uneven temps | Higher fuel use, poorer baking |
| Oven light | Light out | Convenience issue, not heating-related |
If your oven light is out, the range oven light bulb 316538904 is a common replacement part for this model.
A 15-year lifespan assumes safe operation and normal wear. Grease control and correct cleaning methods reduce fire risk and help key components (burners, controls, insulation, and door sealing surfaces) last longer.

What are the most common stove parts to replace?
On the Kenmore 79078803501 gas range, the most commonly replaced parts are the ones that handle heat, ignition, and sealing: surface burner components, igniters, oven light parts, and the oven door seal. These parts wear faster because they see the most heat, spills, and daily use.
- Surface burner head and related hardware: keeps the flame even and properly shaped; clogged ports cause uneven flame or ignition trouble.
- Ignition parts: create spark and deliver gas correctly for reliable lighting.
- Oven light parts: bulb and socket wear out from heat and vibration.
- Oven door seal (gasket): keeps heat in the oven for stable baking temperatures.
- Oven door hardware: hinges and handle parts can loosen or wear from repeated opening.
| Symptom | Likely part to check | Example model-matched part |
|---|---|---|
| Burner lights unevenly or flame is irregular | Burner head, burner ports need cleaning | Range surface burner head 316212400 |
| Oven light out | Bulb, socket | Range oven light bulb 316538904, range light socket 316116400 |
| Oven not holding temperature, heat escaping | Door seal | Range oven door seal 5304498835 |
| Oven burner problems (no heat or weak heat) | Bake burner, gas valve (diagnosis required) | Range bake burner 316404400 |
- Clean first: remove grates, caps, and burner heads; keep burner ports clear to prevent improper ignition and uneven flame.
- Confirm power is off before servicing the oven light; the manual calls for shutting off power and using a 40-watt appliance bulb.
- Inspect the door seal for gaps, tears, or hardened spots.
- Look for loose hardware on handles and hinges if the door feels sloppy.
- Match by model number (79078803501) to avoid fit issues.
Replacing the right wear part restores safe ignition, steady oven temperatures, and efficient cooking. It also prevents secondary issues like overheating controls, longer preheat times, and scorched cookware from uneven flames.
For part locations, removal steps, and safety notes, use the 79078803501 owner’s manual and the 79078803501 installation guide.

What model is my Kenmore gas range?
Your Kenmore gas range model number is printed on the appliance’s rating label; on many ranges like model 79078803501, you’ll find it in the oven door jamb area or on the back of the range. Use the exact model number from that label when ordering parts or checking specs in the 79078803501 owner's manual.
Check these common locations on a Kenmore free-standing gas range:
- Inside the oven door opening, along the door frame (door jamb)
- Behind the storage drawer or lower panel area
- On the back panel near the vent area
- Along the side frame (less common, but possible)
- Turn the oven light on and open the oven door so you can see the frame clearly.
- Look for a sticker or metal plate with MODEL and SERIAL.
- If you do not see it, pull out the bottom storage drawer and look on the frame behind it.
- As a final check, look on the rear panel.
For this Kenmore series, the manual lists the format as 790.7880* (the * is the color code). Your full model is typically the digits without the dot, such as 79078803501.
| What you see on the label | What it means | What to use for parts |
|---|---|---|
| 790.7880* | Model family/series | Use the full model from the label |
| 79078803501 | Full model number | Use this exact number |
| Serial number | Production identifier | Not used to pick most parts |
We use the model number to match the correct burner parts, oven igniter, control overlay, and door hardware; even small differences in a series can change fit, wiring, and gas components.
