How do I reset my Kenmore Elite microwave?
To reset your Kenmore Elite microwave model 72180829500, unplug it (or turn off the breaker) for about 1 minute, then restore power and reset the clock. This clears most control glitches caused by a power interruption and returns the control to normal operation.
Quick reset steps (recommended)
- Unplug the microwave/hood combo from the outlet (or switch the circuit breaker off).
- Wait 60 seconds.
- Restore power.
- Set the clock (a flashing ":" is a common sign the clock needs to be reset).
- Test a simple cook cycle with a cup of water.
If the display is flashing ":" after the reset
A flashing ":" typically means there was a power interruption. After restoring power, set the clock using the steps in the 72180829500 owner's manual.
What a reset will and will not fix
| Symptom | Reset helps? | What to check next |
|---|---|---|
| Display glitch, unresponsive keypad | Often | Power cycle again; check outlet/breaker |
| Flashing ":" | Yes | Set the clock in the manual |
| Runs but does not heat | No | Heating circuit diagnosis; see why is my microwave not heating |
| Dead, no display | Sometimes | Outlet, breaker, internal fuse |
Why it matters
A simple power reset is the safest first step for a Kenmore microwave control issue because many problems are caused by brief outages or voltage dips. Resetting power also helps you confirm whether the issue is a control lockup or a hardware failure.
When to stop and get service
- The breaker trips repeatedly when you start cooking
- You smell burning or see arcing
- The microwave is completely dead after confirming the outlet has power

How do you unlock a Kenmore Elite microwave?
To unlock the controls on your Kenmore Elite microwave model 72180829500, cancel the Child Lock by touching and holding STOP/Clear until LOCKED disappears from the display (about 4 seconds). This restores normal keypad operation. See the 72180829500 owner's manual for the exact keypad label on your control panel.
Quick unlock steps
- Make sure the door is closed.
- Touch and hold STOP/Clear.
- Keep holding for about 4 seconds.
- Confirm LOCKED disappears (or the lock icon turns off).
- Test a simple function like Kitchen Timer or Light.
If it still will not unlock
These checks solve most “microwave locked” complaints on over-the-range microwave/hood combos:
- Press STOP/Clear firmly; some keypads need steady pressure.
- Wipe the control panel dry; moisture can make keys act unresponsive.
- Unplug the microwave (or switch the breaker off) for 1 minute, then restore power and try again.
- If the display is blank or resets repeatedly, check the home circuit and outlet grounding guidance in the 72180829500 installation guide.
- If keys do not respond at all, the issue is usually the control panel or an internal safety circuit; schedule service.
What “Child Lock” does (and does not do)
Child Lock is a control-panel lockout; it prevents keypad use but does not fix heating or door problems.
| Symptom | Most likely cause | What to do |
|---|---|---|
| Shows LOCKED | Child Lock is on | Hold STOP/Clear ~4 seconds |
| No response from any key | Stuck key, moisture, control issue | Dry panel, power reset, service if needed |
| Stops when door opens | Normal safety behavior | Close door, press START/ENTER |
Why it matters
Unlocking the control panel is the fastest way to restore normal cooking, vent fan, and light functions without replacing parts or changing settings.
