Kenmore 79045489502 electric range Parts

For the Kenmore electric range model 79045489502, the most reliable “reset” you can do from the keypad is to cancel Oven Lockout. Press and hold the Oven Lockout pad for 3 seconds until the control unlocks and normal operation returns (the display stops showing “Loc”). See the steps in the owner's manual.

• Cancel Oven Lockout: Press and hold the Oven Lockout pad for 3 seconds; “Loc” clears and the door unlocks.
• Clear a cooking program: Press Cancel/Off (or the stop key on your control) to end a timed bake or delay start.
• Power reset (hard reset): Turn the range breaker OFF for 1 minute, then turn it back ON.
• If “Loc” keeps appearing: Do not press other keys while locked; “Loc” can show while a key is pressed in lockout.
• If the door is locking/unlocking: Wait about 15 seconds for the motorized lock to finish before trying keys again.

When the control is in lockout, the oven door locks and the control pads are locked out. The display shows “Loc”, and the Door Locked indicator flashes while the lock motor is moving.

A “reset” is often needed because the range is simply in control lockout, not broken. Unlocking restores keypad response and prevents unnecessary part replacement.

On the Kenmore electric range model 79045489502, PF means power failure. It shows up when the range briefly loses electrical power or the voltage drops, and it can affect the oven clock and any active cooking cycle. Clear it by pressing Cancel/Stop (or Clear/Off) as described in the 79045489502 owner's manual.

• Press Cancel/Stop (or Clear/Off) once; if PF stays, press it again.
• Reset the clock and re-enter any Bake, Broil, or Timer settings.
• If PF happened during cooking, check food doneness before continuing.
• If PF returns often, try a different outlet circuit (avoid sharing with a microwave or space heater).
• If the display is blank or flickers, turn off the breaker for 1 minute, then restore power.

If PF keeps coming back even when the home power is stable, the issue is often in the range’s power connection or control area. Use the 79045489502 installation guide to confirm the power cord and terminal block connections are correct. If you find heat damage or arcing at the connection point, replace the terminal block using the exact part for this model, such as the terminal block 5304409888.

A power interruption can stop heating mid-cycle and can also cause confusing control behavior until the code is cleared and the clock is reset. Addressing repeated PF events helps protect the electronic control and keeps baking temperatures consistent.

A Kenmore electric range like model 79045489502 typically lasts 13 to 15 years with normal household use and basic maintenance. Heavy use, frequent self-clean cycles, and poor ventilation shorten life; timely part replacement helps it reach the full range.

• Heat stress: frequent high-heat baking/broiling and long preheats
• Self-clean use: high temperatures can stress wiring, sensors, and controls
• Power quality: loose connections or surges can damage the control and terminal block
• Door seal condition: heat leaks make the oven work harder
• Spills and corrosion: especially around surface elements and control areas

If the range is otherwise in good shape, these repairs often restore normal operation:

• Keep the oven vent area clear so heat can escape properly.
• Wipe up spills quickly to prevent baked-on residue and corrosion.
• Avoid slamming the oven door; it protects hinges and the door seal.
• Use self-clean sparingly; use manual cleaning when possible.
• If you smell hot wiring or see flickering display, stop using the range and have it serviced.

Knowing the 13 to 15 year average helps you decide whether to repair (often cost-effective for a bake element or sensor) or plan a replacement if multiple major electrical parts are failing.

For model-specific operating and care guidance, use the 79045489502 owner’s manual.
