Kenmore Elite 79031043802 gas range Parts

A Kenmore gas range like model 79031043802 typically lasts 15 years with normal household use. Consistent cleaning, correct burner flame adjustment, and prompt repair of ignition or temperature issues help you reach that lifespan.

Typical lifespan and what affects it

Most gas ranges land in a similar range, but these factors make the biggest difference:

• Daily heavy cooking versus occasional use
• Keeping burner ports and grates clean to prevent poor combustion
• Using proper flame size so flames do not extend past the pan edge
• Avoiding boilovers and grease buildup that can lead to burner and igniter problems
• Replacing wear items (for example, light bulbs and igniters) when performance drops

Maintenance habits that extend range life

We recommend following the care and safety guidance in the 79031043802 owner's manual.

• Wipe up spills quickly, especially sugary or acidic spills
• Clean burner heads and ports so the flame stays even and blue
• Do not line the oven bottom with foil (it can trap heat and cause damage)
• Use cookware that matches the burner size; keep handles turned inward
• Run self-clean only as directed; remove loose debris first

Quick troubleshooting: when “aging” is really a fixable part

If the range is not heating or lighting reliably, it is often a serviceable component, not end-of-life.

Symptom	Common cause	Part to check for this model
Oven won’t ignite or takes too long to light	Weak/hot-surface igniter	Frigidaire range oven burner igniter 5303935066
Oven temperature is inaccurate	Failing sensor or calibration needed	Frigidaire range oven temperature sensor 316217002
Surface burner flame is uneven	Dirty burner head or incorrect gas flow	Range surface burner head 316212400

Why it matters

A gas range can run safely and efficiently for many years, but poor flame adjustment, grease buildup, and delayed repairs increase wear on key parts like the igniter, gas valve, and burner components.

For a Kenmore Elite gas range model 79031043802, the most reliable reset is a power cycle: turn the range off at the breaker (or unplug it) for about 1 to 2 minutes, then restore power. This clears most control glitches and lockups; see the 79031043802 owner's manual for keypad-specific steps.

Quick reset options (most common)

• Power reset: breaker OFF (or unplug) 1 to 2 minutes, then ON.
• Cancel a cooking mode: press Clear/Off to stop Bake or Broil.
• Unlock a locked oven: use the Oven Lockout key sequence (press and hold the lockout pad for about 3 seconds until the door unlocks).
• Clear odd beeps or display behavior: power reset first, then re-set the clock.
• After any reset: run a short Bake test to confirm ignition and cycling.

If the oven will not heat after a reset

On this model, a “reset” often reveals an underlying ignition or temperature-sensing problem. If the oven does not ignite within about a minute in Bake or Broil, focus on these common causes:

• Weak or failed igniter (glow bar)
• Gas valve not opening
• Temperature sensor out of range
• Loose wiring connection at the igniter or sensor

Parts that commonly fix “no heat” symptoms

Symptom after reset	What to check first	Example part for this model
No Bake ignition	Oven burner igniter	Frigidaire range oven burner igniter 5303935066
Temps inaccurate or error-like behavior	Oven temperature sensor	Frigidaire range oven temperature sensor 316217002
Igniter glows but no flame	Gas valve and wiring	(diagnosis required)

Why it matters

A reset only clears the control state. If ignition is slow or the flame never lights, the range can appear “stuck” even though the control is working. Confirming proper Bake and Broil ignition helps separate a control issue from an igniter, sensor, or gas delivery problem; the 79031043802 installation guide describes verifying burner ignition and proper flame.

On the Kenmore Elite 79031043802 gas range, the model number is printed on the serial plate. You’ll typically find that plate on the oven front frame behind the oven door, or on the drawer side frame, depending on the exact configuration (slide-in vs. drawer style). See the 79031043802 owner’s manual for the serial plate illustration.

Where to look on the range

Check these common serial plate locations first:

• Open the oven door and look along the front frame (the face frame around the oven opening)
• Look behind the oven door on the front frame (common on many models)
• Pull out the storage or broil drawer and check the drawer side frame
• Use a flashlight and look for a silver or white rating label with barcodes
• Record both the model and serial numbers exactly as shown

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

The serial plate is more than a label; it helps us match the correct Kenmore parts and specs for your exact range.

• Confirms the exact model number for parts lookup
• Lists serial number for service history and identification
• Shows burner ratings and the fuel type/pressure the range was set for at the factory

Quick reference

What you need	Where it’s found	When you’ll use it
Model number	Serial plate label	Ordering parts, manuals, diagrams
Serial number	Same serial plate	Service calls, verifying production details
Fuel info/ratings	Same serial plate	Installation checks, burner performance issues

Tips for ordering the right parts

• Copy the model number exactly: 79031043802
• If the label is worn, take a clear photo and zoom in
• Use the model number before choosing items like an igniter, sensor, or gas valve

If your Kenmore Elite gas range model 79031043802 clicks but the oven will not light, the most common cause is a weak oven igniter that is getting power but not heating enough to open the oven gas valve. On this model, normal ignition includes a 30 to 60 second delay before the burner flame appears (see the 79031043802 installation guide).

What “normal” ignition looks like on this model

When you start Bake:

• Current flows to the igniter and it should glow like a light bulb
• The oven gas valve opens only after the igniter gets hot enough
• Flame typically appears after 30 to 60 seconds
• The igniter cycles on and off to maintain temperature

Quick checks we recommend (safe, no disassembly)

• Wait a full 60 seconds after starting Bake to confirm it truly is not lighting
• Look through the oven bottom openings (if visible) for an orange glow from the igniter
• Confirm the range has electrical power (the igniter needs electricity to open the gas valve)
• If you smell gas without ignition, turn the oven off and ventilate the area
• If the igniter glows but no flame appears, plan to replace the igniter

Parts that most often fix “clicking but no light”

Symptom	Most likely part	Example part for this model
Clicking, no flame, igniter does not glow	Oven igniter	Frigidaire range oven burner igniter 5303935066
Igniter glows but still no flame	Weak igniter (most common) or gas valve	Range oven gas valve 316404901
Oven heats erratically or temperature is off	Temperature sensing issue	Frigidaire range oven temperature sensor 316217002

Why it matters

A weak igniter can keep the oven gas valve from opening, so the oven never lights even though you hear clicking. Restoring proper ignition helps the oven heat reliably and prevents repeated ignition attempts.

If your Kenmore Elite gas range model 79031043802 will not reach the set temperature, the most common causes are a weak oven igniter that is not opening the gas valve reliably, a temperature sensing problem, or using the oven before preheat is complete. Use the preheat indicators and then troubleshoot heat and ignition.

Quick checks we recommend first

• Confirm you are waiting for preheat to finish; the control beeps and the “PRE” light turns off when the set temperature is reached (see the 79031043802 owner’s manual).
• Verify the oven is actually cycling; gas ovens heat in cycles and the burner will turn on and off to maintain temperature.
• Avoid opening the door frequently during preheat or baking.
• Check rack position and avoid overcrowding pans; airflow matters for even heating.
• If food is consistently underdone at the end of the recipe time, treat it as an “oven too cool” symptom and move to component checks.

What to look for during ignition (bake)

Your oven uses electric ignition. When you start Bake, the igniter should glow, then the gas valve opens and the burner lights after a short delay (often 30 to 60 seconds). If the igniter glows but the burner lights late, lights weakly, or cycles off too soon, the igniter is a top suspect.

Common symptom-to-part mapping

Symptom	Most likely area	What we do next
Long preheat, weak heat, burner slow to light	Oven igniter	Inspect/replace frigidaire range oven burner igniter 5303935066
Temperature swings, bakes unevenly	Temperature sensor	Test/replace frigidaire range oven temperature sensor 316217002
No bake flame at all (igniter never glows)	Power, wiring, control, igniter	Check wiring and connections; test igniter circuit

Why it matters

A gas oven that cannot reach temperature usually wastes gas, overworks components, and causes undercooked food. Fixing ignition strength or temperature sensing restores normal preheat behavior and steadier baking results.

Safety note before any repair

• Turn off power at the breaker before accessing wiring.
• Shut off the gas supply valve before servicing gas components.
• If you smell gas, do not operate the range; ventilate and address the leak before testing.
