Quick Answer: Resetting a LG Refrigerator#
Check for display mode first: an LG fridge that seems dead but has a lit panel is often in demo mode, cleared by holding the Refrigerator and Ice Plus buttons together until it beeps and normal temperatures return. To reboot the board, disconnect the fridge for five minutes. It will not repair a failed linear compressor or a sealed-system leak.
How to Reset a LG Refrigerator (Step by Step)#
- Check for display mode first: an LG fridge that seems dead but has a lit panel may be in demo mode. Press and hold the Refrigerator and Ice Plus buttons together until the display beeps and normal temperatures return.
- To reset the control board, unplug the refrigerator for five minutes.
- Restore power and wait five to ten minutes for the LG linear compressor to spin up — a quiet fridge in that window is normal, not broken.
- Once running, use Smart Diagnosis through the LG ThinQ app if you want to confirm no cooling fault remains.

LG Refrigerator Model Variations#
InstaView and door-in-door models reset cooling the same way, though the knock-to-see panel reboots separately. The demo-mode combo is Refrigerator plus Ice Plus on most LG panels. Linear and Inverter Linear compressors both need the restart pause before you judge cooling, and Smart Diagnosis is available on most recent models.
When a Reset Doesn't Fix Your LG Refrigerator#
If the box stays warm once demo mode is cleared and the linear compressor has had time to spin up, the sealed system or a fan is the suspect rather than the board. Run Smart Diagnosis to read any stored fault, then check it against our LG error-code guide. The refrigerator-not-cooling, freezing-food, and ice-maker-not-working symptom pages cover the parts worth checking.

LG Refrigerator Reset FAQ#
How do I reset an LG refrigerator?
Clear demo mode by holding Refrigerator and Ice Plus together until it beeps, and if it still will not cool, disconnect the fridge for five minutes. Give the linear compressor several minutes to spin up afterward.
How do I turn off demo mode on an LG refrigerator?
Press and hold the Refrigerator and Ice Plus buttons together until the display beeps and normal temperatures return. A lit but warm LG is usually just in demo mode.
Why is my LG refrigerator not cooling after a power outage?
A surge can drop the fridge into demo mode or need a fresh reboot, so clear demo mode and power-cycle it. If it stays warm after the compressor's window, suspect the sealed system.
How long does an LG refrigerator take to get cold after a reset?
The linear compressor spins up slowly, so allow five to ten minutes to start and several hours to stabilize. A quiet fridge in that window is normal, not broken.
How does LG Smart Diagnosis work on a refrigerator?
Smart Diagnosis lets the fridge report its stored fault to the LG ThinQ app or a support line, so you can read a code without tools. Run it after a reset to confirm no fault survived.
