How to reset Kenmore Elite microwave?
For the Kenmore Elite microwave model 40574153310, the most reliable “reset” is a power reset: unplug the microwave (or switch off the breaker) for about 1 minute, then restore power and set the clock again using the steps in the 40574153310 owner's manual. If the keypad is locked, unlock it first.
Quick reset options (what to try first)
- Power reset (best for glitches): Unplug for 60 seconds, then plug back in.
- Cancel/Stop reset (best for a wrong setting): Press Stop/Cancel to clear the current program.
- Child lock reset (best when buttons do nothing): Press and hold the Lock pad for 3 seconds until “LOC” disappears.
- Clock display reset: Open the door or press the appropriate pad to show the time of day.
If the microwave is locked (LOC on the display)
The manual describes a lock function that prevents operation. To toggle it:
- Press and hold the Lock pad for 3 seconds to lock (you will hear a long beep; “LOC” shows).
- Press and hold the Lock pad for 3 seconds again to unlock (long beep; “LOC” clears).
What “reset” does (and does not) do
| Reset method | What it fixes | What it will not fix |
|---|---|---|
| Power reset | Frozen display, odd behavior after a surge | Heating failures, blown fuse, bad door switch |
| Stop/Cancel | Wrong cook mode, wrong time entry | Lockout, no-power issues |
| Lock toggle | Keypad won’t respond, “LOC” displayed | Power loss, internal electrical faults |
Why it matters
A microwave can appear “dead” when it is simply locked or stuck in an incomplete program. Resetting correctly saves time and helps you avoid unnecessary parts replacement.
If the unit powers on but still will not heat after a reset, use the troubleshooting steps in why is my microwave not heating.

How many watts is the Kenmore Elite microwave?
For Kenmore Elite model 40574153310, the microwave’s rated output (cooking) power is 1000 watts. It’s also normal to see a higher input (power draw) rating on the spec label because the unit uses extra power to run the magnetron and internal components; confirm the exact ratings in the 40574153310 owner's manual.
Output watts vs input watts (what to compare)
When you’re matching recipes or cook times, use output watts.
- Output watts: the heating power that cooks food
- Input watts: what the microwave draws from the outlet while running
- Household power: typically 120V, 60Hz for U.S. countertop units
- Cooking performance: driven mostly by output watts and power level settings
Quick wattage reference
| Rating type | What it means | What to use it for |
|---|---|---|
| Output power (watts) | Cooking power delivered to food | Adjusting cook times and recipe conversions |
| Input power (watts) | Electrical draw from the outlet | Circuit load planning and breaker trips |
Why it matters
Microwave recipes are usually written for a specific output wattage (for example, 900W or 1100W). Knowing your output rating helps you avoid undercooking or overheating when you convert times.
If cooking seems weak (quick checks)
- Make sure you’re using a high power level (often shown as PL10 or 100%).
- Confirm you did not select convection or grill when you meant microwave.
- Test with 1 cup of water; it should heat quickly at full power.
- If the turntable is not rotating, inspect and replace the tray if it’s damaged (see midea microwave glass tray F06015Q00AP).
