If the LG LRMVS3006 appears dead, LG's cooling table splits it three ways: the control is set to OFF on some models, Demo (Display) Mode is on so the lights and display work but cooling is off, or the refrigerator was just installed, restarted or moved. LG's electrical rules also matter: 115 V, 60 Hz on a 3-prong grounded outlet, no outlet that a switch can turn off, and no extension cord. A dark panel can also be Power Saving Mode, so open a door first.
Differential
Likely causes of “LG refrigerator has no power”, and how to tell them apart
- 1
The plug is loose or the outlet is dead
What separates it The display is blank after opening a door and the compartment lights are out
How to confirm Check that the plug is fully seated and try a lamp in the outlet
- 2
A tripped breaker or a switched outlet
What separates it Everything is off and other items on the same circuit are off too
How to confirm Check the breaker and that the outlet is not switch-controlled, which LG says not to use
- 3
The control is off or Display Mode is on
What separates it The panel is lit but not cooling, or OFF appears for 20 seconds
How to confirm Turn the control on and clear Display Mode with Ice Plus pressed three times while holding Refrigerator
- 4
Sabbath mode
What separates it The lights are off and the buttons do nothing but the refrigerator is cool
How to confirm Hold the Freezer and Wi-Fi buttons for 3 seconds to turn Sabbath mode off
Before you touch a setting
Record this first — changing settings destroys the evidence
- Whether the display or any light comes on when you open a door
- Whether the plug is fully seated and whether the outlet works with another device
- Whether OFF, sb or a lock icon appears on the display
Try in this order
0 of 5 completedOpen a door and look
ReversibleIn Power Saving Mode the display is off until a door is opened or a button is pressed, then it stays on 20 seconds. Check for OFF, sb or a lock icon.
Check the plug and outlet
ReversibleLG says use a 3-prong grounded outlet rated 115 V, 60 Hz, not one that a switch can turn off, and no extension cord. Push the plug fully in and test the outlet with a lamp.
Check the breaker
ReversibleLook at the panel for a tripped breaker. Reset it once. If it trips again, stop and have an electrician check the circuit.
Clear Display Mode or Sabbath mode
ReversibleFor OFF, open a door and press Ice Plus three times while holding Refrigerator. For sb, hold Freezer and Wi-Fi for 3 seconds.
Check for a power outage effect
ReversibleAfter a power cut the refrigerator can take 24 hours to reach temperature, and stored ice after a long outage should be thrown away.

Exact questions
Common questions
Why is my LG refrigerator not cooling and the display says OFF?+
It is in Display Mode, a store demo setting that disables all cooling. Open a door and press Ice Plus three times while pressing and holding Refrigerator.
Can I remove the ground prong?+
No. LG says under no circumstances cut or remove the third ground prong from the power cord.
How long to cool after a power cut?+
Up to 24 hours to cool completely once power is restored.
What if the control is OFF?+
On some models the refrigerator control can be set to OFF; turn it on and check the temperature settings.
Does Sabbath mode survive a power cut?+
Yes. LG says once turned on, Sabbath mode is maintained even after a power outage, and it turns off automatically after 96 hours.
Should I move it upright before plugging in?+
If it was moved on its side or stored for a long time, LG says it must stand upright for 24 hours before it is connected to power.
