Kenmore 79045589905 electric range Parts

To reset a Kenmore 79045589905 electric range oven, we recommend doing a hard reset by turning OFF the range’s circuit breaker (or unplugging the cord if accessible) for 3 to 5 minutes, then restoring power and setting the clock. This clears many control glitches and false error displays.

• Turn all surface element knobs to OFF.
• Switch the range breaker OFF (or unplug the range if it’s safely reachable).
• Wait 3 to 5 minutes.
• Restore power.
• Set the clock and test Bake at 350°F.
• If an error code returns, note it before resetting again.

Some resets fail because the control is waiting on a safety input (door lock circuit, temperature sensor, or cooling fan logic).

• If the display shows a lock icon, allow the oven to cool fully, then try Cancel/Off and the hard reset again.
• If the oven overheated recently, a safety device may have opened; after cooling, power-cycling often restores operation.
• If the control beeps and won’t start heating, check for an error code and follow the troubleshooting chart in the 79045589905 owner’s manual.

A hard reset clears temporary electronic faults, but repeated error codes usually point to a real problem such as a failing oven temperature sensor, heating element, or wiring connection. Resetting without addressing the cause can lead to inconsistent baking and repeated shutdowns.

On a Kenmore 79045589905 electric range, an oven that “stops working” is usually caused by a power supply problem (tripped breaker or loose cord connection) or a failed heating or temperature-control component such as the bake element, temperature sensor, or a safety thermostat.

• Confirm the range has power; reset any tripped double breaker fully OFF then ON.
• Make sure the oven is not in a timed or delayed setting; cancel the timer and try BAKE again.
• Set BAKE to 350°F and look for heat: the lower element should glow red during operation.
• Set BROIL and look for heat: the upper element should glow red.
• If the control is dead after the range was stored in cold conditions, let it sit at room temperature for 3 hours before powering it on (cold-start can damage controls).

If power is good but the oven will not heat or heats erratically, these parts are common causes:

• Bake element: cracks, blisters, or no glow during BAKE.
• Oven temperature sensor: incorrect temperature readings can prevent proper heating.
• High-limit thermostat: can open if overheating occurs and stop heating.
• Control or wiring issue: loose connections at the terminal block or damaged harness.

Helpful model-matched parts to consider:

• Range oven temperature sensor 5304504897
• Frigidaire range high-limit thermostat 318578506

An oven can appear “broken” when it is actually protecting itself (high-limit thermostat) or not receiving full 240V power. Starting with simple BAKE/BROIL glow checks helps pinpoint whether the issue is heating, sensing, or power.

For operating checks and feature settings specific to this range, use the 79045589905 owner's manual.

On Kenmore electric range model 79045589905, the model and serial number are printed on the appliance serial plate. For this style of 30-inch electric drop-in range, the serial plate is typically located on the range frame in an area shown in the installation guide.

Look for a paper or metal tag that lists Model and Serial. Check these spots first:

• Along the oven frame behind the oven door opening (door jamb area)
• Around the lower drawer opening (if your range has a storage or warming drawer)
• On the back of the range near the power cord/terminal block cover
• Under the cooktop edge (some drop-in designs place the plate where it is visible when the cooktop is lifted)

• Use a flashlight and look for a rectangular label with a barcode.
• Wipe grease and dust off the frame; the print is often faint.
• Record the full model number exactly as shown (all digits matter for parts like a bake element, surface element switch, or oven temperature sensor).

We use the exact model number to match the correct Kenmore parts and diagrams. Even small model-number differences can change fit and wiring for items like the oven temperature sensor, terminal block, or surface element receptacle.
