Kenmore 79074039311 gas range Parts

To remove the cooktop (top) on your Kenmore 79074039311 gas range, we start by taking off the grates and burner caps, then releasing any burner-base screws and lifting the main top up (it may hinge up or lift off once fasteners are removed). Use the steps in the installation guide for safe shutoff and handling.

Before you start (safety first)

Working around gas and ignition wiring is the main risk. Do these basics every time:

• Turn all burner knobs to OFF and let the range cool completely.
• Shut off the gas supply at the manual shut-off valve.
• Unplug the range (or switch off the circuit breaker).
• Protect the countertop and the cooktop finish with a towel or cardboard.
• Keep screws organized by location so reassembly is straightforward.

Steps to remove the top (cooktop)

Most Kenmore freestanding gas ranges, including model 79074039311, come apart in this general order:

1. Remove the grates.
2. Lift off the burner caps.
3. Remove the burner heads/bases if your version uses screws to secure them.
4. If present, remove screws that secure the burner tubes/venturi to the cooktop.
5. Lift the cooktop:
   • Some tops hinge up from the front once rear clips are released.
   • Others lift off after front and rear fasteners are removed.

What you may need to disconnect (and what not to force)

When the top is raised, you may see igniter wires and gas tubing. Avoid pulling on wiring.

What you see	What we do	Why it matters
Spark igniter wires	Support the top so wires are not strained	Prevents broken connectors and misfires
Burner base screws	Remove only what’s needed to free the top	Prevents stripped threads
Gas tubing/manifold	Do not bend or pry against it	Prevents leaks and alignment issues

Why it matters

Removing the top is often the first step for cleaning spills under burners, fixing weak ignition, or replacing a surface ignition component such as the range surface burner igniter and orifice holder 316536610. Doing it in the right order prevents gas leaks, damaged igniters, and reassembly problems.

On your Kenmore 79074039311 gas range, a bad oven igniter typically shows up as an oven that will not light, takes longer than normal to ignite, or glows but never produces a burner flame. In normal operation, the igniter should glow and the oven burner should ignite within about 60 seconds after you start Bake or Broil (after installation checks are complete). See the owner's manual for operating steps.

Quick symptoms to watch for

• Igniter does not glow at all when Bake or Broil is selected.
• Igniter glows, but the burner does not light within 60 seconds.
• Oven lights sometimes, but ignition is slow or inconsistent.
• You smell gas briefly with no ignition (turn the control off and follow the safety steps in the installation guide).
• Surface burners click normally, but the oven burner will not ignite (points to an oven-ignition issue, not a cooktop electrode).

How to check ignition (safe, no tools)

We recommend using the ignition check described for this range:

1. Set the oven to Bake at 300°F.
2. Watch for the igniter to glow; the burner should ignite within 60 seconds.
3. Let the burner cycle once, then turn the control OFF.
4. If equipped, set to Broil; the broil burner should also ignite within 60 seconds.

What a “good” ignition cycle looks like

What you see	What it usually means	What to do next
Igniter glows, burner lights within 60 seconds	Normal ignition	No repair needed
Igniter glows, burner never lights	Weak igniter or gas valve not opening	Plan to replace the igniter first
No glow at all	Power/control/safety circuit issue or failed igniter	Check power, then test/inspect wiring

Parts that commonly fix “won’t ignite” symptoms

If your oven igniter is weak or failed, these model-compatible parts are common replacements:

• Tappan range oven burner igniter 316489403 (bake ignition)
• Range oven igniter 5304506545 (broil ignition)

Why it matters

A weak igniter can glow but still fail to open the oven safety valve quickly, leading to long preheat times, no-heat complaints, and unreliable baking performance.

On the Kenmore 79074039311 gas range, the model and serial number are on the identification plate located on the right-hand surface of the oven front frame. You can see it by opening the storage drawer, warmer drawer, or broiler drawer (depending on your configuration). See the installation guide for the exact access location.

How to find it (quick steps)

• Turn the oven off and let it cool completely.
• Pull out and open the bottom drawer (storage, warmer, or broiler drawer).
• Look at the right-hand front frame of the oven opening.
• Find the identification plate (it lists model, serial, and other ratings).
• Write down the model number, serial number, and any lot number/letter shown.

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

The identification plate is more than a serial tag. It helps us match the correct parts and specs for your range, including:

• Burner ratings (BTU)
• Fuel type (natural gas vs. LP)
• Gas pressure setting the range was adjusted for at the factory

When you will need the serial number

You will use the serial number most often when you:

• Order replacement parts for the Kenmore 79074039311
• Check compatibility for components like an igniter or temperature sensor
• Request service or look up product documentation

Common parts that often require an exact model/serial match

Part type	Example from this model’s parts list	What it helps fix
Oven burner igniter	Range oven burner igniter 316489403	Oven not heating, weak ignition
Oven temperature sensor	Range oven temperature sensor 316490000	Incorrect oven temperature
Door lock motor and switch	Range oven door lock motor and switch assembly 5304528973	Door won’t lock/unlock during self-clean

Why it matters

Kenmore ranges can look similar across model series, but small design changes affect fit and wiring. Using the identification plate information prevents ordering the wrong igniter, control, or burner component.

A Kenmore gas range like model 79074039311 typically lasts 15 years with normal household use. Keeping burners clean, confirming proper ignition, and addressing weak igniters early helps you get full life from the oven and surface burners.

Typical lifespan and what affects it

Most gas ranges reach the 15-year mark when these conditions are consistent:

• Burners ignite within a few seconds and flames stay steady
• Oven heats evenly and reaches set temperature without long delays
• Gas supply and pressure regulation stay stable
• Spills are cleaned before they bake onto burner heads and caps
• Electrical igniters and wiring stay dry and undamaged

Quick checks that protect longevity

Use these simple checks a few times a year (and anytime performance changes):

• Surface burners: Turn a knob to LITE; you should hear sparking and the burner should light quickly once gas is available.
• Oven bake/broil ignition: When you set Bake, the igniter should glow and the burner should light after a short delay (commonly 30 to 60 seconds).
• Flame quality: Flames should look even and stable across the burner.

For model-specific operating and care details, follow the owner's manual.

Parts that commonly impact performance over time

If ignition gets slow or inconsistent, these are common wear items for gas ranges:

Symptom	Common cause	Example part for 79074039311
Oven won’t heat or takes too long to light	Weak bake igniter	Range oven burner igniter 316489403
Oven temperature swings or seems inaccurate	Temperature sensor drifting	Range oven temperature sensor 316490000
Surface burner won’t spark or won’t light reliably	Igniter/electrode or holder issue	Surface burner igniter and orifice holder 316536610

Why it matters

A gas range can run for years with minor issues, but weak ignition and unstable flames increase cooking time, reduce temperature control, and can lead to more expensive repairs later. Catching ignition and sensor problems early is the easiest way to protect the range’s service life.
