LG refrigerator error codes

Protect food and avoid repeated resets; compressor-start diagnosis should be handled by service.

Check door closure, gasket contact, and items blocking drawers before resetting the display.

Do not attempt refrigerant work. Protect food and arrange qualified sealed-system service.

Do not keep resetting or attempt sealed-system work; use qualified service and protect perishable food.

Check only visible bucket and ice-path issues; service is needed if EID remains.

Avoid forcing the ice maker mechanism and use service if the assembly warning stays active.

Keep food safe and use service if the condenser fan warning returns; do not open powered rear covers.

Reset power once only if the unit is dry and stable; service is likely if communication fails again.

Look for heavy frost around visible vents and avoid chipping ice or opening powered evaporator covers.

Record whether the display says freezer or refrigerator defrost sensor and use service if it returns.

Confirm freezer vents are not blocked and avoid removing covers; service is likely if the fan code returns.

Record the code, keep food safe, and use service if the sensor code returns after one reset.

Confirm the water supply is open and stop if water leaks or the flow warning returns.

Check that the ice bucket and freezer air path are clear, then stop if the code returns after one reset.

Move food away from air vents and keep the doors closed while checking whether cooling recovers.

Keep doors closed, monitor cabinet temperature, and use service if the sensor warning returns.

Exit demo mode using the model's documented button sequence and verify the cabinet starts cooling.
