A:Answer Your owner's manual for the ENERGY STAR® Qualified LG 26.2 Cu. Ft. French Door Smart Wi-Fi Enabled Refrigerator with Dual Ice Maker - PrintProof™ Black Stainless Steel, Model # LFXS26973D advises to run for at least two to three hours before putting food in it. If it hasn't shown any indication of cooling within that time, check to ensure that the refrigerator is not set on Display Mode. The Display Mode (For Store Use Only) disables all cooling in the refrigerator and freezer sections to conserve energy while on display in a retail store. When activated, OFF is displayed on the control panel and the display remains on for 20 seconds. To deactivate / activate this feature, with either refrigerator door opened, press and hold the Refrigerator and Ice Plus buttons at the same time for five seconds. The control panel beeps and the temperature settings display to confirm that Display Mode is deactivated. The default refrigerator temperature is 37 °F (3 °C) and that for the freezer compartment is 0°F (-18 °C)...^IFV
