Kenmore 7909421240E electric range Parts

To reset your Kenmore electric range model 7909421240E, turn the range off, cut power at the breaker (or unplug it) for about 1 minute, then restore power and reset the clock and any oven settings as needed. See the steps in the owner's manual.

• Turn all surface burner knobs to OFF.
• Switch the range circuit breaker OFF (or unplug the power cord).
• Wait 60 seconds.
• Restore power (breaker ON or plug back in).
• Reset the clock and reselect any cooking mode (Bake, Broil, Timed Bake).

This model’s control can be locked. If you see “LOC” or the keypad will not respond, cancel lockout:

• Press and hold the oven lockout pad for 3 seconds.
• Wait about 15 seconds for the door lock motor to finish moving.

A power cycle clears many temporary control glitches after a power interruption. The manual also notes that if power fails, you should turn the range off; when power returns, you will need to reset the clock and oven function.

On Kenmore electric range model 7909421240E, the model and serial number are printed on the identification (serial) plate on the right side of the oven front frame, inside the storage or warmer drawer compartment. Open the lower drawer or lower panel to see the label; confirm the full model number before ordering parts.

Check these spots in this order:

• Open the warmer drawer (some models) or storage drawer (some models) and look along the right side of the front frame
• If your range has a lower cover panel instead of a drawer, remove/open that lower panel and look on the right side
• Use a flashlight; the plate is often on the frame edge where the drawer slides in

1. Turn the range off and let it cool.
2. Pull the storage or warmer drawer fully open.
3. Look at the right side of the oven front frame for a sticker or metal plate.
4. Write down the full model number and serial number exactly as shown.

Kenmore ranges often share similar styling across model families (including 790-prefix models), but parts like a bake element, control overlay, or oven temperature sensor can vary by exact model. Using the full model number prevents ordering the wrong part and saves time on repairs.

For additional diagrams and identification details, use the owner's manual.

On the Kenmore 7909421240E electric range, an oven that “stops working” is usually caused by a power problem, a control fault that needs to be cleared and re-set, or a failed heating or sensing component (bake element, broil element, or oven temperature sensor). Use the owner's manual troubleshooting and control-reset steps first.

• Confirm the range has power; check the house breaker(s) for a tripped circuit.
• If the display is beeping or showing a fault, press STOP/CLEAR to stop beeping and clear the display.
• Reprogram the oven (set Bake temperature again) after clearing.
• If the oven was used during a power interruption, turn the oven off; once power is stable, reset the clock and try Bake again.
• Make sure the controls are set correctly for the function you want (Bake vs Broil).

If the control panel works but the oven will not heat, these parts are the most common suspects for this model:

• Frigidaire range bake element 316413800 (no bake heat)
• Frigidaire range broil element 316203301 (no broil heat, sometimes poor preheat)
• Frigidaire range oven temperature sensor 316490000 (wrong temperature, cycling issues, error codes)

An electric range can look “dead” even when it has partial power. Clearing a control fault and confirming full power prevents unnecessary part replacement; if heat is still missing, focusing on the bake element, broil element, and temperature sensor targets the most common no-heat causes.

On Kenmore electric range model 7909421240E, a surface element usually stops heating because the control is set incorrectly, the element or receptacle connection is burned/loose, or the surface element switch has failed. Start with basic power and control checks, then inspect and test the heating circuit.

• Confirm the correct knob is being used for that burner; the ELEMENT ON light should glow when the burner is turned on (see the owner's manual).
• Turn the knob from OFF to a heat setting and back; a worn switch can act intermittent.
• Try the same element on another receptacle (if your coil element is removable) to see if the problem follows the element or stays with the burner position.
• Check for a household power issue; an electric range can have lights but still lose one leg of power, which affects heating.

Turn off the breaker before opening anything.

• Look for scorching, melted plastic, or loose terminals at the element receptacle (common cause of “element not working”).
• Inspect the coil element for blisters, cracks, or separated spots.
• If the burner only heats on HIGH or won’t regulate, the infinite switch is the likely failure.

• If the burner control is dead or inconsistent, replace the frigidaire range small surface element control switch 316436000.
• If the receptacle is heat-damaged, replace the block 5303935058 (surface element receptacle).
• If the coil itself is bad, match the size and replace with either the frigidaire range coil surface element, 8-in 316442301 or the range coil surface element, 6-in 318372211.

A weak connection at the receptacle or a failing switch can overheat wiring and cause repeated element failures. Fixing the root cause restores normal heating and helps prevent further electrical damage.

On Kenmore electric range model 7909421240E, an F1 (and sometimes similar F-codes) means the electronic oven control detected a fault condition. The fastest next steps are to clear the code, retest, and then focus on the control, sensor circuit, and wiring using the owner's manual.

• Press STOP/CLEAR to stop beeping and clear the display.
• Set BAKE and a temperature to reprogram the oven; watch to see if the code returns.
• If it comes back, write down the exact code and when it happens (idle, preheat, during bake).
• Turn off power at the breaker for 1 minute, restore power, and retest.
• If the oven is hot (after cooking or self-clean), let it cool completely and try again.

F1 is most often tied to the electronic control system or an input the control relies on.

If troubleshooting points to temperature sensing, the oven sensor is a common repair item.

• Frigidaire range oven temperature sensor 316490000

When the control detects a fault, it can shut off heating or cycle incorrectly. Fixing the underlying cause prevents nuisance beeping and helps keep baking temperatures accurate.
