Before trying to reset an LG refrigerator after an outage, establish whether it has power at all. A dark cabinet and display are a different starting point from a refrigerator with lights on but warm food compartments. Record the model and any code before changing anything.
No lights or display
LG’s power guide starts with the cord, supply circuit and outlet. If the plug is safely accessible and everything is dry, check that it is fully inserted and look for visible cord damage. A known-working small device can help check an accessible outlet. An outlet fault needs an electrician; if the outlet works but the refrigerator stays off, LG directs the owner to service. Do not handle a wet, damaged or hot connection. LG no-power guidance.
Lights on, but the compartments are warm
Check the selected temperature, whether the doors close and whether food blocks the internal vents. Those three are owner checks. If they are fine and the compartments stay warm, the cause is inside the machine, and a power outage by itself doesn’t tell you which part.
LG’s own reset for a control upset by a power event is to unplug the refrigerator, wait 5 minutes and plug it back in. LG display and power-fluctuation guidance. Do it once. If a code is displayed, photograph it and look it up in the model documentation. Clearing a message with a reset doesn’t mean cooling has recovered. Avoid repeated unplugging while trying different internet button sequences.
Give the technician a clear starting point
Tell us when power returned, whether the refrigerator ever resumed cooling, and which compartment is affected. Include the model number and display photo. An outage can upset the control, damage a board or simply coincide with a fault that was already developing, so we test before naming a part.
