Kenmore 79077449804 gas range Parts

A Kenmore gas range like model 79077449804 typically lasts 15 years with normal household use. Keeping burners clean, preventing grease buildup, and fixing ignition or temperature issues early helps you get the full service life from the oven and cooktop.

Typical lifespan and what affects it

Most ranges reach their expected lifespan when heat, gas flow, and airflow stay consistent.

• Heavy daily cooking shortens lifespan; light to moderate use extends it
• Grease buildup under burner heads and in the oven can create overheating and wear
• Weak ignition (slow lighting) strains igniters and can lead to no-heat complaints
• Poor temperature control can cause longer bake times and extra cycling
• Proper installation and correct gas pressure help prevent repeat failures

Maintenance that pays off (high impact)

Use these habits to reduce common gas range failures.

• Clean around surface burners regularly; do not let grease accumulate
• Keep the oven bottom and door frame areas free of baked-on spills
• Ventilate well during the first self-clean cycle and follow the cycle length guidance
• If a surface burner goes out on LOW, adjust the LOW flame setting as described in the installation guide
• Replace worn consumables (like light bulbs) before they fail during cooking

Quick “repair vs replace” guide

What you’re seeing	Most common cause	Usually worth repairing?
Oven won’t heat or heats slowly	Weak igniter	Yes
Oven temperature is off	Temperature sensor drift	Yes
Burner won’t light consistently	Dirty burner head or igniter issue	Yes
Gas smell or poor flame pattern	Gas supply/regulator issue	Service recommended

If your oven is not heating reliably, the oven igniter is a frequent fix on this platform; see the tappan range oven burner igniter 316489403. For inaccurate baking temperatures, check the frigidaire range oven temperature sensor 316490000.

Why it matters

A 15-year lifespan assumes safe, efficient combustion and stable oven temperature. Small issues like slow ignition or a burner that will not stay lit on LOW can increase wear, raise cooking times, and lead to bigger repairs.

On the Kenmore 79077449804 gas range, you adjust the surface-burner flame by setting the burner to its lowest position, removing the knob, and turning the small adjustment screw inside the valve stem with a thin-bladed screwdriver until the flame stays lit and does not extend past the pan edge (see the 79077449804 installation guide).

Before you start (safety and setup)

• Turn the burner OFF before removing any knob.
• Keep burner caps and burner heads installed whenever a burner is in use.
• Do not let spills, food, or cleaners enter the orifice holder opening.
• Use a pan on the grate when testing flame size.
• If you smell gas, stop and have the range checked by a qualified technician.

Steps to adjust the low flame (simmer) setting

1. Push in and turn the knob to LITE until the burner ignites.
2. Quickly turn the knob down to the lowest setting.
3. If the burner goes out, turn the knob OFF.
4. Pull the surface burner control knob straight off.
5. Insert a thin-bladed screwdriver into the hollow valve stem and engage the slotted screw.
6. Adjust the flame:
   • Turn counterclockwise to increase flame size.
   • Turn clockwise to decrease flame size.
7. Reinstall the knob and re-test: the flame should stay lit at the lowest setting.

What the “right” flame looks like

Use this quick checklist while you test:

• Flame is steady and does not flutter out when you gently blow across it.
• Flame does not extend beyond the outer edge of the cookware.
• You are not leaving the knob in LITE after ignition.

Flame behavior	What it usually means	What to do
Goes out on LOW	Low setting too low	Increase slightly (counterclockwise)
Tall on LOW	Low setting too high	Decrease slightly (clockwise)
Uneven/yellow tips	Burner parts dirty or misaligned	Clean and reseat cap/head, then retest

Why it matters

A properly adjusted low flame helps prevent nuisance flame-outs, improves simmer control, and reduces the chance of flames licking past the pan edge, which can be a burn and ignition hazard.

A bad oven igniter on Kenmore gas range model 79077449804 usually shows up as delayed ignition or no ignition at all. In normal operation, the igniter should glow and the burner should light within about 30 to 60 seconds; longer delays, weak ignition, or no glow point to an igniter problem.

Quick signs you can see (and smell)

• Oven takes much longer than usual to preheat
• Igniter glows but the burner does not light within about 60 seconds
• No glow from the igniter when you set BAKE or BROIL
• You notice a gas odor because gas is not lighting promptly
• Burner flame is weak, uneven, or drops out during cycling
• Igniter looks cracked, chalky, or heavily coated

What “normal” looks like on this model

The installation instructions for this style of electric-ignition oven burner describe a short delay before flame appears.

What you observe	What it usually means	What to check next
Igniter glows, flame lights in 30 to 60 seconds	Normal ignition cycle	No repair needed
Igniter glows, but no flame (or very delayed flame)	Igniter is weak or gas valve is not opening	Inspect igniter; consider replacing igniter
No igniter glow at all	Power, wiring, control, or igniter is open	Check outlet/breaker; inspect wiring harness

Safe checks before replacing parts

• Do not try to operate the electric ignition oven during a power failure; reset oven controls to OFF.
• Verify the range has power (clock/display on, breaker not tripped).
• If the igniter glows but the burner will not light, stop and ventilate if you smell gas.
• Inspect the igniter and its connector for heat damage.
• Use the wiring diagram/testing steps in the 79077449804 installation guide if you are doing electrical checks.

Parts that commonly fix “no bake” or “no broil” ignition

If symptoms match, these are common repairs for this model:

• Tappan range oven burner igniter 316489403 (bake ignition issues)
• Range oven igniter 5304506545 (broil ignition issues on many configurations)

Why it matters

A weak igniter can prevent the oven gas valve from opening at the right time, causing slow preheat, temperature swings, and occasional gas odor from delayed ignition. Restoring proper ignition helps the oven heat safely and maintain steady baking performance.

On the Kenmore 79077449804 gas range, the most commonly replaced parts are ignition and heating-related items (igniters, burner components, and sensors) plus wear items like oven racks, door seals, and light bulbs. These parts take the most heat and use, so they fail first.

Most common replacement parts (and what they fix)

• Oven igniters: oven will not heat, slow preheat, weak or no ignition
• Oven temperature sensor: oven temperature is inaccurate or swings too hot/cold
• Surface burner parts (cap/head/igniter): clicking, delayed ignition, uneven flame
• Oven door seal: heat loss, longer cook times, hot exterior surfaces
• Oven racks: rust, bent racks, poor sliding
• Oven light bulb: light out (this model uses a 40-watt appliance bulb)

Model-matched parts we see replaced often

Symptom	Likely part to check	Example model-matched part
Oven won’t ignite or takes a long time to light	Oven igniter	Tappan range oven burner igniter 316489403
Oven temp seems wrong	Oven temperature sensor	Frigidaire range oven temperature sensor 316490000
Oven light is out	Appliance bulb	Appliance light bulb, 40-watt 316538904
Burner flame is uneven or ignition is delayed	Burner head/igniter assembly	Range surface burner head 316212400
Heat leaking around oven door	Door seal	Range oven door seal 5304498835

Quick checks before you order parts

• Confirm the problem is consistent (every bake cycle, every burner use, etc.).
• Inspect and clean burner ports and caps; clogged ports cause uneven flame and ignition issues.
• Watch the oven ignition: a weak igniter often causes slow lighting and poor heating.
• Check the door seal for gaps, tears, or hardened spots.
• Replace the oven light safely: power off, let everything cool, then install a 40-watt appliance bulb.

Why it matters

Replacing the correct wear part restores safe ignition, stable oven temperature, and efficient cooking. It also prevents secondary issues like longer preheat times, uneven baking, and excess heat escaping around the door.

For model-specific care steps (like knob removal for cleaning, cooktop cleaning cautions, and oven light replacement), follow the 79077449804 owner's manual.

On Kenmore gas range model 79077449804, the model and serial number are printed on the identification (serial) plate on the right side of the oven front frame, inside the storage drawer or warmer drawer compartment. Use the location diagram in the 79077449804 owner's manual to spot it quickly.

Where to look on the range

Check these spots in order (they are the most common for this Kenmore range design):

• Open the storage drawer (or warmer drawer, if your model has one) and look at the right-hand side of the oven front frame
• Look for a metal or foil identification plate with the model and serial number
• If the drawer is hard to open, remove it fully so you can see the frame clearly
• Write down the model number, serial number, and any lot number/letter shown

What the identification plate tells you (and why it matters)

Besides the model number, the plate typically lists key details used for correct parts and setup, including burner ratings and the fuel type and pressure the range was set for at the factory. That information helps us match the right Kenmore range parts and avoid ordering the wrong component.

Quick checklist before you order parts

Use this checklist so the part match is accurate the first time:

• Confirm the model reads 79077449804 (all digits)
• Record the serial number exactly as shown
• Note any lot number/letter on the plate
• Compare your appliance finish and features (storage drawer vs. warmer drawer)

Common label locations (comparison)

Location	How to access	Typical for
Storage drawer compartment	Pull out the bottom drawer	Many free-standing ranges
Warmer drawer compartment	Pull out the warmer drawer	Some models with warmer drawer
Oven front frame (right side)	Look along the front frame edge	This Kenmore design

If the label is missing or unreadable

If the plate is damaged, use the diagram and guidance in the 79077449804 installation guide to confirm the drawer and frame areas to inspect, then match parts by visible component style (burner heads, igniters, control panel layout) and any numbers stamped on the part itself.
