A Kenmore gas range like model 79070402012 typically lasts 15 years with normal household use. Consistent cleaning, correct burner flame, and quick repair of ignition or temperature issues help you reach that lifespan; see the maintenance guidance in the 79070402012 owner's manual.

What affects lifespan the most

• Cleaning habits: keeping spills and grease off burners, grates, and the oven bottom reduces corrosion and flare-ups.
• Ignition health: slow or failed lighting strains components and can lead to no-heat complaints.
• Oven temperature accuracy: chronic overheating or underheating increases wear and cooking time.
• Ventilation: using a vent hood and cleaning its filter helps reduce grease buildup around the range.
• Gas supply setup: correct installation and stable gas pressure support reliable burner operation (use the 79070402012 installation guide for setup checks).

Quick maintenance checklist (monthly)

• Wipe the cooktop and burner caps; keep burner ports clear.
• Check burner flames; they should be steady and mostly blue.
• Clean the oven interior after heavy spillovers.
• Inspect the power cord and outlet; a weak connection can cause intermittent ignition.
• Replace dim or failed oven lights with the correct bulb type.

Common “wear” items vs. longer-life components

Item	Typical symptom when failing	What we usually replace
Ignition parts	Clicking but no flame, delayed ignition	Range oven burner igniter 5304509706
Oven sensing	Oven temp swings, bakes unevenly	Range oven temperature sensor 316233903
Oven light	Light out, flickers	Appliance light bulb, 40-watt 316538904

Why it matters

A 15-year lifespan assumes the range heats efficiently and safely. When ignition gets weak or the oven runs off-temperature, cooking times increase and parts cycle harder, which shortens overall life.

If your Kenmore gas range model 79070402012 is not igniting, the most common causes are loss of electrical power to the range (needed for spark/glow ignition), the gas supply or regulator being OFF, or a failed oven ignition component such as the igniter. Use the checks below, then confirm control settings in the 79070402012 owner's manual.

Quick checks we recommend first

• Confirm the range is plugged in and the outlet has power (electric ignition needs power).
• Check for a home power outage; the oven will not ignite without power.
• Verify the gas supply is ON and the gas regulator valve is in the ON position.
• Make sure the oven controls are set correctly for the cooking mode you want (Bake or Broil).
• If surface burners are also acting up, clean burner ports and ignition ports after the burner is OFF and cool.

Most likely parts when the oven won’t light

A weak or cracked igniter is a top cause of “no ignition” on many Kenmore gas ranges.

Symptom	What it usually points to	What to do next
No heat, no ignition attempt	No power, control not set	Verify outlet power and settings in the manual
Clicking/glow but no flame	Weak igniter or gas flow issue	Inspect igniter; confirm regulator ON
Intermittent ignition	Igniter weakening, wiring issue	Check connections; consider igniter replacement

If you suspect the igniter, the model-specific replacement part is the range oven burner igniter 5304509706.

Safety notes before troubleshooting

• Turn the oven OFF and let it cool before inspecting or cleaning.
• Never block oven bottom slots, holes, or passages; restricted airflow can create a carbon monoxide hazard.
• Avoid spraying cleaner on electrical controls or switches to prevent shorts and sparking.

Why it matters

On model 79070402012, ignition depends on both utilities: electric power for the ignition system and gas flow through the regulator. A simple power or regulator setting issue can look like a bad part, so these checks prevent unnecessary replacement.

On our Kenmore 79070402012 gas range, a bad igniter shows up as repeated clicking with no flame, delayed ignition (sometimes a “whoosh”), a dim or non-glowing oven igniter, or a gas odor without ignition. Use the safety steps in the 79070402012 owner’s manual before testing.

Signs that point to an igniter problem

• Surface burner keeps sparking at LITE but does not light
• Burner lights slowly, then ignites suddenly
• Oven burner will not light; igniter glows weakly or not at all
• You smell gas and the burner does not ignite (stop and ventilate)
• Ignition works sometimes, then fails again (intermittent)

Quick checks we use to rule out simple causes

• Turn the knob fully to LITE; visually confirm the burner lights, then adjust flame
• Clean and dry the burner cap and ports; clogs can cause partial flame around the burner head
• Confirm the range has power (electronic ignition needs electricity)

Testing and what the results mean

Test/observation	What it indicates	Next step
Strong spark but no flame	Burner/cap alignment or clogged ports	Clean, dry, reseat parts
No spark on any surface burner	Power, wiring, or ignition circuit issue	Check outlet, then wiring/service
Oven igniter glows but burner never lights	Weak hot-surface igniter	Replace igniter

Part that commonly fixes oven ignition

If the oven burner is slow to light or will not light, the oven igniter is a common repair:

• Range oven burner igniter 5304509706

Why it matters

Fast, consistent ignition prevents delayed lighting and reduces the chance of gas odor during startup.

A gas stove (gas range) like Kenmore model 79070402012 is made up of the cooktop burner system (burners, caps, grates, valves, igniters), the oven burner system (burner, igniter, gas valve), and the control and safety components that regulate gas flow and temperature. For diagrams and names, use the 79070402012 owner's manual.

Main parts you will see on a gas range

• Surface burners (burner heads and burner ports) that mix gas and air to create a stable flame
• Burner caps and grates that spread heat and support cookware
• Knobs and burner valves that control gas volume and flame size
• Ignition system (spark electrode and wiring) that lights the surface burners
• Oven burner and igniter that light and maintain the bake flame
• Oven temperature sensor that helps the control maintain the set temperature
• Pressure regulator that stabilizes incoming gas pressure (natural gas or LP/propane)

Parts on this model that commonly come up in repairs

If you are troubleshooting “won’t light,” “weak flame,” or “oven not heating,” these parts are frequent suspects on the 79070402012:

• Range oven burner igniter 5304509706 (oven lights slowly or not at all)
• Range oven temperature sensor 316233903 (temperature swings, underbakes, overbakes)
• Range pressure regulator 5304521339 (gas flow issues after installation or conversion)
• Appliance light bulb, 40-watt 316538904 and range light socket 316116400 (oven light problems)

Quick “what it does” reference

Part/system	What it does	Common symptom when it fails
Surface burner + electrode	Lights and shapes the cooktop flame	Clicking but no flame, uneven flame
Oven igniter	Opens the oven gas valve by drawing current and igniting gas	No bake, long preheat
Pressure regulator	Keeps gas pressure consistent	Weak flames, poor heating
Temperature sensor	Feeds oven temperature to the control	Inaccurate oven temperature

Why it matters

Knowing the correct part names helps you match the right replacement and diagnose faster. For example, cleaning burner ports and keeping the electrode area free of spills can restore ignition, while an aging oven igniter often causes slow ignition and low oven heat.

To change a spark electrode igniter on your Kenmore gas range model 79070402012, we shut off power, remove the grate and burner parts, swap the electrode and wire connection, then reassemble and test on LITE. Use the 79070402012 installation guide for access details.

Before you start (safety)

• Turn the burner knob to OFF and let the cooktop cool.
• Shut off power at the breaker (spark ignition is electrical).
• Remove the burner grate, burner cap, and burner head.
• Keep screws and small parts organized.
• Avoid pulling on the wire itself; grip the connector.

Replace the electrode (typical surface burner)

1. Remove the screw holding the electrode to the burner base or orifice holder.
2. Pull the wire connector straight off the electrode terminal.
3. Transfer the connector to the new electrode (crimp only if your connector style requires it).
4. Reinstall the electrode and tighten the mounting screw.
5. Reinstall burner head and cap so they sit flat; then reinstall the grate.

Test and troubleshoot

• Restore power; turn the knob to LITE and verify ignition.
• After it lights, turn the knob off LITE to set the flame (the ignitor keeps sparking if left on LITE).
• If it clicks but will not light: reseat the burner cap and dry/clean burner ports.

Symptom	Likely cause	Fix
All burners click when one is on LITE	Normal on this design	Light the selected burner; then adjust flame
No spark at one burner	Loose connector, cracked electrode	Reseat connector; replace electrode
Spark present, no flame	Gas off or clogged ports	Verify gas; clean ports

Why it matters

A tight connector and correctly positioned electrode give reliable ignition and prevent repeated clicking. The use and care information also notes that when any knob is set to LITE, multiple surface ignitors may spark even though only one burner should ignite.
