LG Refrigerator Error Code 1-2-3-4-5

The sequential blinking of control panel lights indicates the refrigerator is in store demo mode. In this mode, the compressor and cooling system are shut off while the display and lights remain active. The refrigerator will not cool food until demo mode is deactivated. This is a software-level setting and does not indicate a hardware fault.

No. Because the compressor is disabled in demo mode, neither the refrigerator nor the freezer compartment will maintain safe temperatures. Food stored inside will warm to room temperature over time, creating a food safety risk. Deactivate demo mode before loading food into the unit.

There is no cost to fix this condition. Demo mode is a software setting that is deactivated through a button combination, requiring no replacement parts and no service call. If you are unable to deactivate demo mode using the prescribed button sequence, a technician visit could range from around $75 to $150 for a diagnostic call, though the resolution itself involves no parts.

Open both the refrigerator and freezer doors simultaneously. Press and hold both door switches in at the same time, then while holding them, press and hold the Temperature Adjust button for 5 seconds. When demo mode is successfully deactivated, the sequential blinking should stop and normal cooling operation will resume.

A standard power reset, such as unplugging the unit and plugging it back in, will typically not clear demo mode. The setting is stored in the control board and requires the specific button sequence using the door switches and Temperature Adjust button to disable it properly.
