Kenmore 79047833403 electric oven Parts

On a Kenmore oven like model 79047833403, an F3 error points to an oven temperature sensing problem, most commonly the oven temperature sensor circuit (sensor, wiring, or the electronic control). Clear the code, then check the sensor and connections before replacing parts.

What to do first (safe, quick checks)

• Press STOP/CLEAR to stop the beeping and clear the F-code, then try baking again.
• If the code returns, turn off power at the breaker for 1 minute, then restore power.
• If the oven was recently moved or serviced, check for a loose connector at the sensor harness.
• If the oven overheats or won’t heat correctly, stop using it until the cause is corrected.
• Use the troubleshooting steps in the owner's manual.

What usually causes an F3 code

In most Kenmore electric wall ovens, F3 is triggered when the control reads an out-of-range temperature signal.

Common causes include:

• Failed oven temperature sensor (open, shorted, or drifting resistance)
• Damaged or loose wire harness/connector between sensor and control
• Failed electronic oven control (control board)

Parts that commonly fix the problem

If your diagnostics point to a failed component, these model-matched parts are commonly involved:

Symptom	Most likely part	Part to consider
F3 returns quickly after reset	Temperature sensor circuit issue	Range oven temperature sensor 316217002
F3 plus intermittent operation	Loose/burned wiring connection	Wall oven wire harness 318231735
Sensor tests good but F3 persists	Control not interpreting sensor signal	Frigidaire wall oven control board 316418556

Why it matters

The oven temperature sensor is the control’s main feedback for regulating heat. When the signal is wrong, the oven can underheat, overheat, or shut down with an F-code to protect the appliance and improve cooking accuracy.

An electric oven like the Kenmore 79047833403 is built around heating elements, temperature sensing, airflow and venting, lighting, and electronic controls. These parts work together to heat evenly, regulate temperature, and keep the oven safe to operate; see the owner's manual for your model’s feature layout.

Main parts you will find in most electric wall ovens

• Bake system: bake element (often hidden under the oven floor on some designs) and the oven cavity/liner
• Broil system: broil element at the top of the oven cavity
• Temperature control: oven temperature sensor and electronic control board
• Airflow and cooling: oven vent (warm air exits through the vent trim area); some models use a blower/cooling fan that can run after shutoff
• Lighting: oven light bulb, light socket, and lens/cover
• Door and sealing: door glass, hinges, and door seal (gasket)

Common Kenmore 79047833403 parts you can replace

If you are troubleshooting heat, lighting, or control issues, these are common service parts for this model:

• Range oven temperature sensor 316217002
• Frigidaire wall oven control board 316418556
• Range broil element 318255605
• Range oven light bulb 316538904
• Crosley range oven door seal 318053120

Quick “what it does” reference

Part or system	What it does	Common symptom when it fails
Broil element	Provides high top heat for broiling	No broil heat, uneven browning
Temperature sensor	Tells the control the oven temperature	Oven too hot, too cool, or temperature swings
Control board	Runs bake/broil functions and timing	Dead display, erratic heating, won’t start
Oven vent and blower	Moves heat and protects components	Excess heat at trim, fan runs after cooking

Why it matters

Knowing the major components helps you narrow down a problem fast. For example, an oven that will not regulate temperature usually points to the temperature sensor or control, while a no-light issue is typically the bulb, socket, or lens/cover.

If your Kenmore 79047833403 wall oven will not turn on, start by checking for a home power issue (tripped breaker or blown fuse) and then confirm the control settings are correct. After a power interruption, this oven stays off until you reset the clock and select a cooking function (and turn off Sabbath mode if it is enabled). See the owner's manual for the exact reset and control steps.

Quick checks we recommend first

• Verify the oven has power at the breaker panel; reset the breaker fully (OFF, then ON).
• If a fuse blew, replace it and make sure it is seated tightly.
• Make sure the oven controls are set correctly (a function like Bake must be selected).
• If the display is blank after a power outage, reset the clock and reselect the oven function.
• Check whether SAb (Sabbath mode) is showing; if it is, turn Sabbath mode off.

Power outage and Sabbath mode (common causes)

The manual notes two situations that make the oven appear “dead” even though nothing is broken:

Situation	What you see	What to do
Power failure/interruption	Oven shuts off and will not restart automatically	Turn the oven off, then reset the clock and select a cooking mode again
Sabbath mode enabled	Display shows SAb and the control stops beeping/responding normally	Turn Sabbath mode off using the key sequence in the manual

If it still will not power up

If the breaker is good and the controls are set correctly, the issue is usually in the oven’s power feed or control circuit. These checks help narrow it down:

• Inspect the power connection area for heat damage or loose wiring.
• Check the terminal block for signs of overheating or arcing.
• If the display is dead but power is present, the electronic control may be the failure point.

Model-matched parts that are commonly involved in “no power” symptoms include the terminal block 5304409888 and the wall oven control board 316418556.

Why it matters

A wall oven that will not turn on is often a simple reset after a power interruption, but repeated breaker trips or heat damage at the power connection can lead to unsafe operation. Restoring solid power and correct control operation prevents nuisance shutdowns and protects the control board.
