A dark display on the LG LRMVS3006 is often a setting, not a fault. LG's manual says the display stays off in Power Saving Mode until a door is opened or a button is pressed and then stays on for 20 seconds; Display Mode shows OFF and disables cooling; and Sabbath mode (sb) turns off lights and buttons on models that have it. The Lock function also disables every other button. Interior LED lamp failures are a technician repair, and the door lights depend on a proximity sensor.

Before you touch a setting

- Whether the display is blank, shows OFF, sb or a lock icon
- Whether the interior lights, door lights or both are out
- Whether flooring or objects near the door are reflective, and how long since installation
Try in this order
0 of 5 completedWake the display
ReversibleOpen a door or press a button. LG says in Power Saving Mode the display stays off until then, and once on it remains on for 20 seconds.
Check for OFF, sb or a lock
ReversibleOFF means Display Mode, sb means Sabbath mode and a lock icon means the Lock function is on, and each has its own button combination in the manual.
Unlock the panel
ReversiblePress and hold the Lock button for about three seconds. LG says the function disables every other button on the display, and that it is off when power is first connected.
Check the door lights
ReversibleLG says the LED door lighting relies on a proximity sensor in the center of the door that needs to detect a person, and reflective flooring can stop it working. It may take 30 seconds to work after installation.
Call for interior lamp faults
ReversibleLG says the interior LED lamp is not a customer replacement and service should be performed by a qualified technician. Do not try to open the lamp cover.
