Kenmore 79073439312 gas range Parts

On Kenmore gas range model 79073439312, the model and serial number are printed on the identification plate on the right-hand surface of the oven front frame. You typically access it by opening the storage drawer, warmer drawer, or broiler drawer, depending on your range configuration (see the 79073439312 installation guide).

Where to look on the range

Check these spots in this order:

• Open the bottom drawer (storage, warmer, or broiler drawer) and look at the right side of the oven front frame
• Look for a metal or foil identification plate with the model and serial number
• Write down the model number, serial number, and lot number/letter (if shown)
• If the drawer is hard to open, remove the drawer per the 79073439312 owner’s manual instructions

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

The identification plate is more than just the model number. It can also list burner ratings and the fuel and gas pressure the range was set up for at the factory. That information helps us match the correct Kenmore gas range parts and avoid ordering the wrong component.

You need this	Why we ask for it
Model number (example: 79073439312)	Ensures parts fit your exact range design
Serial number	Helps confirm production version changes
Lot number/letter (if listed)	Helps narrow down part revisions

Tips for reading and recording the number

• Use a flashlight; the plate is often in a shaded area behind the drawer front
• Copy the number exactly, including all digits
• Take a clear photo so you can zoom in later
• Keep the info with your Use and Care paperwork for future repairs

On Kenmore gas range model 79073439312, you replace a spark electrode by removing the burner cap and head, disconnecting the electrode wire, swapping the electrode, then reassembling and testing ignition. Use the 79073439312 installation guide for burner-cap placement and ignition checks.

Before you start (safety and access)

• Turn all burner knobs to OFF.
• Shut off the gas supply at the shutoff valve.
• Unplug the range (spark ignition is electrical).
• Let the cooktop cool completely.
• Remove grates, then lift off the burner cap and burner head for the burner you are servicing.

Step-by-step: replace the spark electrode

1. Expose the electrode: With the burner cap and head removed, locate the ceramic spark electrode near the burner.
2. Remove the mounting screw: The electrode is typically held by a small screw.
3. Disconnect the wire: Pull the connector straight off the electrode terminal (do not pull on the wire itself).
4. Install the new electrode: Set the electrode into the same position and secure it with the screw.
5. Reconnect the wire: Push the connector fully onto the new electrode terminal.
6. Reassemble correctly: Reinstall the burner head and cap, making sure the cap sits properly.

Post-repair checks (what “normal” looks like)

Per the installation instructions, when you turn a surface knob to LITE you should hear sparking and the burner should light within about 4 seconds after air is purged from the gas line. Also, all igniters may spark at the same time, even though only one burner lights. Review the ignition test steps in the 79073439312 installation guide.

Symptom after replacement	Most likely cause	What to check
Clicking but no flame	Gas not reaching burner	Gas valve open, burner head/cap seated, ports not clogged
No clicking/spark	Electrical ignition issue	Power restored, wire fully seated, harness/switch issue
Spark is weak or intermittent	Poor connection or cracked electrode	Tight connector, electrode not damaged, correct positioning

Why it matters

Correct electrode position and correct burner cap placement help the burner ignite quickly and prevent delayed ignition, uneven flames, and repeated sparking.

On the Kenmore 79073439312 gas range, the oven igniter should glow like a light bulb when you set Bake or Broil; if it never glows, the most common causes are a failed igniter, no power to the range, or a wiring/control issue preventing voltage from reaching the igniter.

Quick checks (start here)

• Confirm the range has power (clock/display on, outlet working, breaker not tripped).
• Set Bake to 300°F and watch through the oven bottom vents or burner area for up to 60 seconds.
• If the igniter glows but there is no flame after 60 seconds, the igniter can still be weak and not drawing enough current to open the gas valve.
• If the igniter never glows, focus on power, wiring, and the igniter circuit.
• If you smell gas, turn the oven off and ventilate the area.

What “normal” looks like on this model

Per the installation checks, when the oven is set to operate, current flows to the igniter, it glows, then the oven valve opens and the burner lights after a short delay.

What you see	What it usually means	What to do next
No glow at all	No power to igniter, failed igniter, open wiring, or control not sending power	Check power, then inspect wiring and test igniter
Glow, no flame (after 60 sec)	Weak igniter or gas valve not opening	Replace igniter first in most cases
Glow, flame lights, then cycles	Normal operation	No repair needed

Parts that commonly fix “no glow”

• Range oven igniter 5304509706 (most common failure)
• Loose/burned wire connections at the igniter harness
• Control or safety circuit issue (less common)

Why it matters

A non-glowing igniter means the oven burner cannot light. Even when an igniter glows, a weak igniter can prevent the gas valve from opening, causing no-heat or intermittent heating and poor baking results.

For model-specific operating steps and troubleshooting notes, use the 79073439312 owner's manual.
