Kenmore 79078733406 gas range Parts

On the Kenmore 79078733406 gas range, an igniter problem shows up as a burner that will not light within a few seconds, repeated clicking/sparking with no flame, or an oven that takes longer than about 60 seconds to ignite after you start BAKE. Use the 79078733406 installation guide for the correct ignition checks and timing.

Quick symptoms to look for

• Surface burner: you hear sparking but the burner does not light within about 4 seconds (after air is purged from the gas line).
• Surface burner: burner lights only after a long delay, or only if you keep turning the knob back to LITE.
• Oven bake: igniter glows but the burner flame does not appear within 30 to 60 seconds.
• Oven bake: burner cycles oddly (short on time, long off time) and temperature performance is poor.
• Any burner: you smell gas without ignition; turn the control OFF and ventilate the area.

What to check first (safe, no-disassembly checks)

1. Confirm power: electric igniters need household power; make sure the range is plugged in and the outlet works.
2. Watch and listen: for surface burners, you should hear sparking at LITE and see the burner light quickly.
3. Clean and reseat burner parts: keep burner caps and heads properly positioned; spills and cleaners must not enter the gas orifice holder opening.
4. Purge air after a gas interruption: if gas was shut off, leave the knob at LITE until the burner ignites.
5. Oven timing check: set BAKE to 300°F; ignition should occur within about a minute.

Surface vs. oven igniter: what “normal” looks like

Location	What you should see/hear	Typical normal time
Surface burner	Sparking at LITE, then steady flame	About 4 seconds (after air is purged)
Oven bake burner	Igniter glows like a light bulb, then burner lights	30 to 60 seconds

When a part replacement is likely

If the oven will not ignite on BAKE and you have confirmed power and gas supply, the ignition system components are common suspects. For this model, a related part you may see listed is the igniter 316489401 (broil igniter); match the failure to the correct burner circuit before ordering.

Why it matters

A weak or failing igniter can prevent the gas valve from opening at the right time, causing delayed ignition, poor heating, and inconsistent cooking results.

A Kenmore gas range like model 79078733406 typically lasts 15 years with normal residential use. Regular cleaning to prevent grease buildup and prompt repair of ignition or burner issues are the biggest factors in reaching that lifespan; see the 79078733406 owner's manual for care guidance.

Typical lifespan and what affects it

Most gas ranges reach their full service life when heat, gas flow, and ventilation stay consistent.

• Cleaning habits: grease and food soils accelerate wear on burners, igniters, and controls
• Ventilation: using a hood or fan reduces heat and grease accumulation around the range
• Usage level: heavy daily cooking shortens life compared to average household use
• Maintenance timing: replacing small wear parts early prevents bigger failures
• Proper installation: correct gas and electrical setup reduces nuisance problems (see the 79078733406 installation guide)

Maintenance checklist that helps you get the full 15 years

Use these habits to reduce common gas range failures (weak ignition, uneven flames, overheating, and control issues).

• Wipe spills after cooking; do not let grease accumulate on the cooktop or around burners
• Keep burner heads seated correctly and ports clear
• Avoid excess cleaner residue near heat sources (residue can ignite)
• Ventilate well during the first self-clean cycle and follow the recommended self-clean duration
• If the oven light fails, replace it with the correct part for this model (example: range oven light bulb 316538904)

Quick reference: what “normal” looks like

Item	Typical expectation	What to do if it’s not happening
Burner ignition	Clicks and lights within a few seconds	Clean burner head and check igniter condition
Flame pattern	Even, steady blue flame	Clean ports; verify burner head alignment
Oven performance	Reaches set temp and holds it	Check bake burner and gas valve operation
Self-clean	2 to 4 hours depending on soil level	Use the cycle length recommended in the manual

Why it matters

A 15-year lifespan assumes the range stays free of grease buildup and is operated as intended. Grease accumulation and delayed repairs are two of the fastest ways to shorten the life of a gas range.

To change a spark electrode igniter on your Kenmore gas range model 79078733406, we remove the burner parts, disconnect the electrode wire, swap in the new electrode, then reassemble and test ignition. Keep spills and cleaners out of the orifice holder opening during the repair.

Safety first (gas and electricity)

• Turn all burner knobs to OFF and let the cooktop cool.
• Shut off the gas supply at the range shutoff valve.
• Unplug the range (or switch off the breaker) so the igniters cannot spark.
• Work in good light; avoid dropping screws into the burner box.
• Do not allow spills, food, or cleaning agents to enter the orifice holder opening (this can cause ignition problems).

Step-by-step: replacing the surface spark electrode

1. Remove the grate, then lift off the burner cap and burner head.
2. Locate the ceramic spark electrode next to the burner.
3. Remove the mounting screw holding the electrode.
4. Disconnect the electrode wire connector.
5. Install the new electrode:
   • Push the connector fully onto the electrode terminal.
   • Seat the electrode in the holder and secure it with the screw.
6. Reinstall the burner head and cap (make sure they sit flat and aligned).
7. Restore power and gas, then test.

What “normal” ignition looks like on this model

Your 79078733406 uses electronic ignition; when you turn a knob to LITE, you should hear sparking and the selected burner should light quickly once gas is present.

Quick check table

What you see	Most likely cause	What we do next
Sparks but no flame	Gas not reaching burner, cap/head misaligned	Re-seat cap/head; confirm gas is on
Delayed ignition “whoosh”	Electrode bumped, dirty burner parts	Clean and align; verify electrode position
No spark at any burner	No power to range	Check outlet/breaker; restore power

Why it matters

A correctly installed electrode and properly seated burner head/cap help the burner light within a few seconds and prevent delayed ignition, uneven flames, and repeated clicking.

On Kenmore gas range model 79078733406, the cooktop (top) is not removable, so we do not remove the entire top panel for service. For cleaning and most burner access, we remove the grates and burner pieces only; follow the steps in the installation guide.

What you can remove for cleaning and burner access

• Remove the surface grates.
• Lift off the burner caps.
• Lift off the burner heads (where applicable) and clean ports.
• Wipe the cooktop surface with hot, soapy water; avoid harsh cleaners on stainless.
• Reinstall parts dry and seated correctly so the burner lights evenly.

If you need deeper access (gas and electrical safety)

If you are trying to reach wiring, igniters, or gas components, we service this range from the front, back, or inside the oven cavity, not by lifting the cooktop.

• Turn all controls to OFF.
• Shut off the gas supply valve.
• Unplug the range (or switch off the breaker).
• Pull the range forward only as far as needed to access the rear (protect the floor).
• After service, reconnect and check for gas leaks per the 79078733406 owner's manual.

Quick comparison: removable vs non-removable cooktops

Task	What you do on 79078733406	What you do on some other ranges
Clean spills	Remove grates/caps; wipe surface	Lift cooktop (if designed to lift)
Access surface burners	Remove caps/heads; clean ports	Lift cooktop for full access
Access wiring/gas parts	Pull range out; remove panels as needed	Often lift cooktop first

Why it matters

Trying to force a non-removable cooktop can bend the top, damage burner alignment, or create ignition and gas-leak problems. Using the correct access points keeps the burner flame stable and the range safe to operate.

On the Kenmore gas range model 79078733406, an oven that “stops working” is usually caused by a loss of electrical power to the ignition/control system, a failed oven ignition component, or an electronic control fault (often shown as an F-code). Start by resetting controls to OFF and checking power.

Quick checks we recommend first

• Confirm the range has power (clock/display on, outlet and breaker OK).
• Press STOP/CLEAR to cancel a stuck cycle or clear beeping.
• If an F-code appears, write it down; clear it with STOP/CLEAR and see if it returns.
• Make sure the oven door is fully closed (some functions will not run with the door open).
• If the issue started during an outage, keep the oven OFF until power is stable (electric ignition models should not be operated during a power failure).

Most common causes (and what they look like)

Symptom	Likely cause	What to do next
No heat, no ignition sound	No power to controls or control not set	Verify power; reset controls; reprogram bake per the 79078733406 owner's manual
Beeping with an F-code (example: F11)	Electronic control detected a fault	Clear with STOP/CLEAR; if it recurs, use the recorded code for diagnosis per the 79078733406 owner's manual
Oven won’t start after outage	Controls left ON during power loss	Turn oven OFF; once power returns, reset clock and function settings
Oven light out but oven otherwise works	Burned-out bulb or socket issue	Replace the range oven light bulb 316538904 (and inspect the socket if the new bulb does not light)

Why it matters

This model uses electric ignition for the oven. That means the oven depends on household power for safe ignition and control operation; power interruptions and control faults can make the oven appear “dead” even when gas is available.
