When to Call a Professional
Call a professional if the refrigerator doesn't start cooling after 24 hours of exiting demo mode, if the control panel is unresponsive, or if you cannot locate the correct button combination for your specific LG model.Frequently Asked Questions
Why is my LG refrigerator in demo mode?
Demo mode is typically activated accidentally by pressing certain button combinations, or the refrigerator was previously used as a display model in a store. It's designed to show the display features while disabling cooling to save energy.
How long does it take for my LG refrigerator to cool after exiting demo mode?
After successfully exiting demo mode, it typically takes 24 hours for the refrigerator to reach proper operating temperatures. You should hear the compressor start within a few hours.
What buttons do I press to turn off demo mode on my LG refrigerator?
Most LG refrigerators require pressing and holding 'Refrigerator' and 'Ice Plus' buttons for 5 seconds. Some models use 'Freezer' and 'Refrigerator' or 'Energy Saver' and 'Fridge' buttons. Check your manual for model-specific instructions.
Will I lose my food if my LG refrigerator is in demo mode?
If caught early (within 4-6 hours), your food should be fine. However, extended time in demo mode means no cooling, so perishables may spoil. Check food temperatures and discard anything that feels warm or shows signs of spoilage.
