Setting the Clock: The Basic Steps

To set the clock on a Samsung microwave, press the Clock button once, enter the time using the number pad, then press Clock again to confirm. The exact button location and display vary slightly between Samsung models, but this three-step sequence works on nearly all of them. The clock will show on your microwave's display even when the unit is off.

Most Samsung microwaves display time in 12-hour format by default, though some models let you switch to 24-hour time through the settings menu. If your microwave is brand new or the power has been cut, the display will show dashes or zeros until you set it for the first time.

Key Takeaways

  • Press the Clock button, type your time on the number pad, then press Clock again to save it.
  • If your microwave has no dedicated Clock button, look for a button labeled "Time" or "Set" on the control panel.
  • The clock will not display while the microwave is running, but it will return once the cycle ends.
  • If you enter the time incorrectly, press Clock again and re-enter the correct time before the display resets.
  • Some Samsung models require you to hold the Clock button for two to three seconds rather than pressing it once.

Finding the Clock Button on Your Control Panel

The Clock button is usually located in the upper left or upper right corner of the microwave's control panel, near other time-related buttons. On some Samsung models, it sits directly above or below the number pad. Look for a button with the word "Clock" printed on it, or sometimes just a clock icon.

If you cannot find a dedicated Clock button, check for buttons labeled "Time," "Set," or "Menu." Older Samsung models and compact units sometimes combine the clock function with another button. Your microwave's manual will show the exact location for your specific model number, which you can find on a sticker inside the microwave door or on the back of the unit.

Entering the Time Correctly

After pressing the Clock button, the display will show dashes or zeros waiting for input. Type the time using the number pad in the format your microwave expects. Most Samsung microwaves want you to enter four digits for the time: two for the hour and two for the minutes. For example, to set 2:30 p.m., press 0, 2, 3, 0.

Do not press the colon button or any other symbol — just the numbers. If your microwave is set to 24-hour time, enter 14 instead of 2 for 2 p.m. Once you have typed all four digits, press the Clock button again to confirm. The time will lock in and display on the screen.

What to Do If You Make a Mistake

If you enter the wrong time before pressing Clock the second time, press the Clock button again to cancel and start over. The display will return to the dashes or zeros, and you can type the correct time. Do not press any other buttons — pressing a number pad button after you have already entered your time will add extra digits instead of replacing what you typed.

If you have already pressed Clock to confirm and the wrong time is now showing, press the Clock button once more to re-enter the time. You will have a few seconds to type the new time before the microwave locks it in again. If the display goes dark or returns to showing the incorrect time, straightforward repeat the three-step process from the beginning.

Switching Between 12-Hour and 24-Hour Time

Most Samsung microwaves come set to 12-hour time (with a.m. and p.m.), but some models let you change this in the settings menu. To access this option, look for a button labeled "Menu," "Settings," or "Options" on your control panel. Press it and use the arrow buttons to scroll through the menu until you find "Time Format" or "Clock Format."

Not all Samsung models have this feature — if you cannot find a time format option in the menu, your microwave is locked to 12-hour display. Check your manual for your specific model to confirm whether this setting is available. Once you switch to 24-hour time, you will need to re-enter the clock using the four-digit format (for example, 14:30 instead of 2:30 p.m.).

Why the Clock Disappears When the Microwave Runs

When you start a cooking cycle, the display switches from showing the clock to showing the remaining cooking time. This is normal behavior on all Samsung microwaves. Once the cycle ends or you stop the microwave, the clock will reappear on the display automatically. The clock itself keeps running in the background — it does not reset or lose the time you set.

If the clock does not return after the cooking cycle ends, press the Stop or Cancel button to clear the display. The clock should appear again within a few seconds. If the display remains blank or shows only zeros, the microwave may have lost power or the clock may need to be reset.

Resetting the Clock After a Power Outage

If your home loses power, your Samsung microwave will lose the clock setting. When power returns, the display will show dashes or zeros again. straightforward follow the three-step process to set the clock once more: press Clock, enter the time, and press Clock again to confirm.

Some Samsung models have a battery backup that keeps the clock running during brief power cuts, but this is not standard across all models. If you want to avoid resetting the clock every time the power goes out, check your manual to see if your unit has this feature. If it does and the clock still resets, the backup battery may need replacement — contact Samsung support for guidance on your specific model.

Frequently Asked Questions

What if my Samsung microwave has no Clock button?

Look for a button labeled "Time," "Set," "Menu," or "Options." On some compact models, the clock function is combined with another button. Press the button and look for a clock or time icon on the display. Your microwave's manual will show which button controls the clock for your specific model.

Can I set the clock while the microwave is cooking?

No. You must wait until the cooking cycle ends or you stop the microwave. Once the display returns to showing the clock, you can press the Clock button and enter a new time if needed.

Why does my clock show the wrong time even after I set it?

You may have entered the time in the wrong format. Check whether your microwave is set to 12-hour or 24-hour time. If it is set to 24-hour time and you entered 2 for 2 p.m., it will display as 2 a.m. instead. Press Clock again and re-enter using the correct format for your microwave's time setting.

Does the clock keep running if I unplug the microwave?

No. Unplugging the microwave will erase the clock setting. When you plug it back in, the display will show dashes or zeros, and you will need to set the time again. Only microwaves with a battery backup will retain the clock during an unplugging.

How long do I have to press the Clock button to confirm the time?

You should press it once and release when ready. On some older Samsung models, you may need to hold it for two to three seconds instead. If pressing once does not work, try holding the button down briefly. Your manual will specify the correct method for your model.
