On the LG LRMVS3006 the first checks are on the panel, not inside the machine: LG says a refrigerator that has power and lights but is warm may be in Display Mode, which disables all cooling and shows OFF for 20 seconds, or the control may be off. Then LG lists a defrost cycle (wait 30 minutes), a fridge installed or moved in the last day (it can take 24 hours to reach temperature, and 24 hours upright after moving on its side), a room above 110 F, a clogged condenser cover, and blocked air vents.
Differential
Likely causes of “LG refrigerator is not cooling enough”, and how to tell them apart
- 1
Display Mode, a store-demo setting that turns cooling off
What separates it The lights and buttons work but nothing cools and OFF appears on the display for 20 seconds
How to confirm Open a refrigerator door and press Ice Plus three times while holding the Refrigerator button; a beep confirms it
- 2
The refrigerator was just installed, moved or restarted after a power cut
What separates it Temperatures are warm during the first day and the compressor is running
How to confirm Wait up to 24 hours; if it was moved on its side it must stand upright 24 hours before power
- 3
A hot room or a clogged condenser cover
What separates it The compressor runs constantly and the back or sides feel warm to touch
How to confirm Check the room stays under 110 F and vacuum the cover and vents without removing the coil panel
- 4
Food blocking the air vents between the freezer and the fresh food section
What separates it The fresh food side is warm while the freezer is cold, with packages against the back wall
How to confirm Feel for airflow at the vents with your hand and move packages away from them
Before you touch a setting
Record this first — changing settings destroys the evidence
- The temperatures showing on the display and the set values, plus whether OFF or sb appears
- How long since it was installed, moved or without power
- Whether the compressor runs, and whether food is against the back wall vents

0 of 5 completedRead the display
ReversibleLook for OFF, which LG says means Display Mode, or sb, which is Sabbath mode. Both leave the lights or buttons working while cooling behaves differently, and both are set by button combinations you can undo.
Turn Display Mode off if it shows OFF
ReversibleOpen a refrigerator door, then press the Ice Plus button three times while pressing and holding the Refrigerator button. The panel beeps and the temperatures show to confirm it is deactivated.
Set the temperatures
ReversiblePress the Refrigerator or Freezer button until the target shows. LG's defaults are 37 F for the refrigerator and 0 F for the freezer. Adjust one step at a time and wait for the temperature to settle.
Check airflow and the condenser
ReversibleMove packages away from the vents in the divider wall, and vacuum the condenser cover and vents with a brush attachment. LG says not to remove the panel that covers the condenser coil.
Give it time and check the room
ReversibleAfter installation, a move or a power cut, allow up to 24 hours for each compartment to cool. LG says the room must stay under 110 F, and a defrost cycle can warm things for about 30 minutes.

Exact questions
Common questions
Why is my LG LRMVS3006 warm but the lights work?+
LG says it may be in Display Mode, which disables all cooling to save energy on a showroom floor. OFF appears on the panel and the display stays on for 20 seconds.
How do I turn Display Mode off?+
Open either refrigerator door, then press the Ice Plus button three times while pressing and holding the Refrigerator button. The panel beeps and the temperatures appear.
What temperatures should it be set to?+
LG's default is 37 F (3 C) for the refrigerator and 0 F (-18 C) for the freezer. Milk on the inner shelf should be cold and ice cream firm.
How long does a new refrigerator take to cool?+
LG says up to 24 hours for each compartment to reach the desired temperature after installation or after power is restored.
What if it was moved on its side?+
LG says it must stand upright for 24 hours before it is connected to power.
Is the compressor supposed to run all the time?+
At about 70 F room temperature LG says to expect it to run about 40 to 80 percent of the time, and more when it is warmer.
What room temperature can it work in?+
LG says it should not run above 110 F (43 C), and food can freeze in the fresh food section below 41 F, so it should not run below 55 F (13 C).
What does sb on the display mean?+
Sabbath mode is on, on models that have it. Touch the display, then hold the Freezer and Wi-Fi buttons for 3 seconds to turn it off.
