If you have a Samsung fridge, you might notice some frost or ice buildup inside the freezer or fridge compartments. This can affect the cooling performance of your fridge and cause food spoilage or water leaks. To prevent this, you need to put your Samsung fridge in defrost mode regularly. In this post, we’ll explain what defrost mode is, how to put your Samsung fridge in defrost mode, and answer some common questions you might have.
Defrost mode is a feature that melts away any frost or ice that accumulates inside your Samsung fridge. You can put your Samsung fridge in defrost mode manually by pressing and holding the ice maker button on the control panel for about 3 seconds until the ‘Off’ LED lights up.
Alternatively, you can put your Samsung fridge in defrost mode automatically by using the forced defrost feature.
How to Put Your Samsung Fridge in Defrost Mode Manually
The easiest way to put your Samsung fridge in defrost mode is to use the ice maker button on the control panel. This button controls the ice making function of your fridge, but it can also be used to turn off the ice maker and initiate defrost mode. Here are the steps to put your Samsung fridge in defrost mode manually:
- Locate the ice maker button on the control panel. Depending on your fridge model, the ice maker button might look different or be located in a different place. It might say ‘Ice Maker Off’ or have an icon of an ice cube with a slash through it.
- Press and hold the ice maker button for about 3 seconds until the ‘Off’ LED lights up. This will turn off the ice maker and start defrost mode.
- Wait for about an hour for defrost mode to complete. You might hear some dripping or cracking sounds as the frost or ice melts into water and drains away.
- Press and hold the ice maker button again for about 3 seconds until the ‘On’ LED lights up. This will turn on the ice maker and resume normal operation.

How to Put Your Samsung Fridge in Defrost Mode Automatically
Another way to put your Samsung fridge in defrost mode is to use the forced defrost feature. This feature allows you to enter a special diagnostic mode on your fridge and select different options, such as full defrost (FD) or refrigerator defrost (rd). Here are the steps to put your Samsung fridge in defrost mode automatically:
- Enter diagnostic mode by pressing and holding the freezer and lighting buttons on the control panel for about 10 seconds, or until you hear a beep.
- Press the lighting button repeatedly until you see ‘Fd’ or ‘rd’ on the display. ‘Fd’ stands for full defrost, which will defrost both the freezer and fridge compartments. ‘rd’ stands for refrigerator defrost, which will only defrost the fridge compartment.
- Press any other button to confirm your selection and start defrost mode.
- Wait for about an hour for defrost mode to complete. You might hear some dripping or cracking sounds as the frost or ice melts into water and drains away.
- Exit diagnostic mode by pressing and holding any button for about 10 seconds, or until you hear a beep.
