LG Refrigerator Diagnostic Mode
To put an LG refrigerator into the diagnostic or test mode, do the following:
Test Mode 1
Go to the control panel and find the function that controls the freezer temperature. It is labeled Freezer Temp.
Press the Colder and Express Freezing buttons simultaneously. In this mode, some of the features of the refrigerator still work.
Test Mode 2
For this mode, press the Colder and Express Freezing buttons simultaneously. Hold both buttons for about 3 seconds. You can run diagnostics on the damper, defrost heater, and the LEDs on the display showing 2.
Test Mode 3
Hold the Colder and Express Freezing buttons simultaneously for more than 3 seconds. You can run diagnostics when the damper is shut and the fan and compressor are off.
Note that some LG refrigerators have test buttons. Consult the user manual for the refrigerator to determine if yours has one. If it does, press it for the stipulated length of time. Afterward, press the Colder and Express Freezing buttons simultaneously.
To exit the diagnostic or test mode, press the same combination of buttons and hold them for about 3 seconds. You can also press the test button if there is one. Doing this resets the refrigerator and restores it to its previous settings.
How to Put an LG Refrigerator in Defrost Mode
To put an LG refrigerator in defrost mode, press the Colder and Express Freezing buttons simultaneously for more than 3 seconds. The compressor and fan will go off, and the damper will shut down at this time. The defrost heater will come on and begin defrosting the unit.
While this is happening, the display LEDs 1,3,5, and 7 will be on.
You can also press the same buttons once to get it into test mode. Then, press the Adjust temperature button of the freezer and the Ice Plus button at the same time for more than 3 seconds while the refrigerator is in test mode 1. You will get the same result.
Some LG refrigerators have a defrost button you can press to get the unit in the defrost mode.
To get the refrigerator out of defrosting mode, simply press the defrost button again.
LG Refrigerator Stuck in Defrost Mode – How to Fix
If you find your LG refrigerator stuck in defrost mode, locate and check the defrost thermostat. It may be that the contacts are not shutting down. If that is so, you may be putting hot food into the refrigerator, causing the contacts not to cool enough to shut down.
If that is not the case, then the defrost timer is the problem. It should advance the system out of the cycle. So if the unit is stuck, the timer is jammed and the heater can’t turn off.
Find the defrost timer on the lower kick-plate or on the control panel on the refrigerator’s back. Turn the round notch on it counterclockwise using a flat-head screwdriver. Turn it until the fan stops working. This resets the timer and if it is still working, the fan should start working again.
However, if the process does not happen, the timer is bad and needs a replacement.
What Is Energy Saver Mode on LG Refrigerator?
The energy saver mode on an LG refrigerator means the refrigerator runs optimally during times of infrequent use while saving energy. It is perfect for when you are not home, say you are on vacation.
Temperatures in both compartments drop lower than usual but there is no increase in energy consumption. Instead, there is a reduction in energy use. This mode is also called Eco mode.
To put the refrigerator into Eco mode, press the Eco-Friendly key once. To get it out of the mode, press the key once more.
Do LG Fridges Have Sabbath Mode?
Some LG fridges have the Sabbath mode feature and you can set the mode by pressing a combination of buttons. The Sabbath mode lets the fridge be in use even during religious times, especially Jewish holidays.
While in the mode, you cannot accidentally use many features of the fridge so as not to violate religious laws. However, the defrost function of the refrigerator remains functional to keep the contents fresh.
To put the fridge into the Sabbath mode, close every door and drawer. Then, press the Freezer Drawer and WiFi keys simultaneously for about 3 seconds. Both LEDs of the fridge will turn on.
To turn the mode off, press the same combination of buttons again.
Note: While in the Sabbath mode, drawers and doors close automatically when you open them. And the mode automatically turns itself off after 96 hours or 4 days.

How to Tell If LG Refrigerator Is in Demo Mode
If an LG refrigerator displays OF F with no cooling in the freezer and refrigerator compartments, it is in demo mode. This mode is usually used while the refrigerator is on display at stores in order to save energy. So if your LG refrigerator is new, it is likely to be in demo or display mode.

Take your finger off the Ice Plus button and while your finger is still on the refrigerator button, press the Ice Plus button 3 times.
How to Get an LG Refrigerator Out of Demo Mode
To get an LG refrigerator out of demo mode, open any of the doors of the refrigerator and press the Ice Plus and Refrigerator buttons simultaneously for 5 seconds. The temperature display will come on as the control panel beeps. This is for models LG made in 2018 or earlier.
For models made in 2019 or later, open the refrigerator’s right door. Now, press the Ice Plus and Refrigerator buttons simultaneously. Next, remove your finger from the Ice Plus button and press it 3 times in quick succession with your finger still on the Refrigerator button.
