Set the Clock on a Samsung Microwave + Eco, Demo & Reset Fixes

Learn how to set the clock on a Samsung microwave with simple steps for all models. Includes fixes for Eco mode, demo mode, power settings, and reset tips.

Setting Time Using the Clock Button

Three Samsung models are designed to use the clock button to set the time. For this, first press the clock button and then use the number pad to plug in the time. Now, press the clock button again to pick morning or evening hours. On some models, you can skip this step. Confirm your entry by pressing the enter or start button. 

Some microwave ovens allow you to change the time using the settings button. To do this, press the number “9” button on the number pad. Now, press the OK button. Use the number pad to enter the time. Press Ok to confirm and end the program. 

Also, note that some Samsung ovens designate morning and evening times using military time. On those, 1-12 is 1 a.m. through noon ad 13-24 is 1 p.m. through midnight.

No Clock Button–Other Methods (Newer Models)

Many newer Samsung models have removed the physical “Clock” button to create a sleeker look. Depending upon your model, TIME might be set through the power, options, or settings buttons.

Power Button

Some Samsung models have a hidden clock feature. This feature can only be accessed using the power level button. To reset your clock this way, hold down the power level button for three seconds and use the number pad to enter the time. 

You will use the power level button to set the morning or evening time. Press it once for the AM time and twice for the PM time. Finally, press either the OK or the Start button to confirm.

Options Button

Some Samsung models have a clock feature where you use the options button to set the time. Press the options button and then press “9” on the number pad. Press the OK button and plug in the time on the number pad. Press okay to confirm and finish. 

• The New Method: Press the Options or Settings button (represented by a gear icon on touch models). Use the arrow keys or the dial to scroll to “Clock” or “Time,” then press OK/Start to begin the entry.

Arrows and OK Button

These aren’t the only ways you can set time on your Samsung microwave. Some simpler models use arrows. On these models, you start by pressing the OK button and then pressing the left or right arrows to set the time. Press the ok button again once you set the hour. 

Now, use the arrows to set the time for the minutes and press OK again. You will see the correct time displayed on the control panel. 

SmartThings Auto-Sync to set Time- Bespoke

If you have a newer Samsung microwave (BESPOKE or Smart Dial), you no longer need to set the clock manually.

• Once the microwave is connected to the SmartThings app via Wi-Fi, it will automatically sync the time with your smartphone. This is especially helpful for Daylight Saving Time transitions, as the microwave will update itself overnight without any user input.

What is Eco Mode on a Samsung Microwave?

Eco Mode (short for Ecological or Economic Mode) is a software-controlled setting found in almost all modern appliances— and the goal is to minimize power use when the unit is not actively working.

The eco mode turns off the display, which includes the clock, and the control board functions when the microwave isn’t in use. If the screen is black but the unit works when you open the door, Eco Mode is likely on.

A frequent “troubleshooting” complaint is that the clock disappears shortly after being set.

How to fix it: If the display is dark, look for the Eco Button (usually marked with a small leaf icon). Pressing it once will wake the display. To keep the clock on permanently, you may need to disable Eco Mode in the “Settings” or “Options” sub-menu.

How to Unlock a Samsung Microwave?

• The Child Lock Key (3 Seconds): Locate the button labeled Child Lock, L, or the Clock icon with a small padlock symbol. Press and hold it for 3 seconds until the “L” or lock icon disappears and the microwave beeps.
• The Multi-Button Shortcut: If there is no dedicated lock button, press and hold the Start and Stop/Cancel buttons simultaneously for 3 seconds. This is a common “hidden” unlock sequence for newer touch-control models.
• The “Eco Mode” Toggle: On some models, the lock is tied to the Eco/Power Save button. If the display is blank or unresponsive, press and hold the Eco button to wake the control panel and disengage the safety lock.
• Hard Power Reset: If the keypad remains unresponsive after trying the button combinations, unplug the microwave for 60 seconds. This forces the control board to reboot and clears the child lock memory.
• Check the Door Switch: If the microwave isn’t “locking” but simply won’t start, ensure the door is fully latched. A faulty door interlock switch can mimic a locked control panel by preventing the “Start” command from engaging.

How to Reset Your Microwave?

A minor glitch in your microwave can often be corrected by resetting your microwave oven. Resetting will clear the control board on your microwave where things like program buttons and cook times will work again. 

Resetting your microwave is easy. Unplug it or turn off the circuit breaker. Wait for 10 minutes and then plug it back in. Your oven should work correctly unless it has a major problem.

How to Set Power Level on Samsung Microwave

All Samsung microwaves are set on the high power level by default. It will use 900 watts of power to cook when it’s set to high. Most microwave manufacturers, including Samsung, use high as a default power level because it works for the majority of foods and is the most efficient.

Samsung microwaves come with 10 different power levels that you can adjust to cooking any number of dishes. Power levels are numbered 1 to 10, with 1 being the lowest and 0 being the highest. There are two ways to do it and which way you use depends on your Samsung model. 

Samsung Models With a Keypad

These are some of the easiest microwaves to make different selections because the numbers correlate with the power levels. Setting your power level on this Samsung model involves two steps. 

First, press the power level button. It is also the 1 button if you don’t have a specific power level button. Next, use the numbers to select the power level to pick your desired amount of heat.

Samsung Models Without a Keypad

You don’t need a keypad to select a different power level for your microwave. Your Samsung microwave that doesn’t have a keypad will either have a microwave button or a mode selector dial you can use to select the microwave option. 

Once you press the microwave button or chose the microwave option on the dial, you can choose your power level in one of three ways. You can use the arrow keys or keep pressing the microwave button until the power level you want appears on the display screen. You can also turn the multi-function dial until you get to the right power level. 

Press OK or set the level by pressing down on the multi-function selector dial. 

How to Turn off Demo Mode in Samsung Microwave

To disable Demo Mode on a Samsung microwave, you must access the Options or Settings menu, usually represented by a gear icon. Once inside the menu, scroll to the “Demo” or “Shop” setting and select “Off” or “0” to restore full functionality.

If your model lacks a dedicated settings button, you can often toggle this mode by pressing and holding the Start and Stop/Clear buttons simultaneously for five seconds. When successful, the “d” or “Demo” icon will disappear from the display, and the microwave will begin heating again. If the display remains stuck, a hard reset—unplugging the unit for 60 seconds—is the most effective way to force the control board out of the demonstration loop.

Frequently Asked Questions

Why does my microwave oven clock run slow?

Your microwave oven clock may run slow when you don’t provide a dedicated circuit for it. This can cause your microwave to lose time over months. Your outlet needs to have 60Hz of power consistently and a lack of proper power consistently can cause your clock to lose efficiency.
