LG Refrigerator (Top Freezer) Ad error code

Difficulty: Hard · Cost: $100–$300 · Duration: Requires professional service

The Ad error means your LG refrigerator's automatic door motor did not complete its movement within the expected 5 second window. This error appears on models with an automatic door opening or closing mechanism. The motor is responsible for moving the door to either its fully open maximum position or its closed home position — when it cannot reach either position in time the refrigerator displays this code as a protective measure. There are no user steps to resolve this error and the unit requires a professional repair service.

Common causes

Door motor has malfunctioned or failed and cannot complete its movement
Obstruction is blocking the door from reaching its full open or closed position
Door motor mechanism is worn out or damaged
Wiring to the door motor is loose or damaged

How to fix it

1

Check around the door for any objects or obstructions preventing it from moving freely
2

Remove any obstruction and unplug the refrigerator for 5 minutes then plug it back in
3

If Ad returns after clearing any obstruction and resetting contact a qualified technician to inspect the door motor
