LG Refrigerator (French Door) AS error code

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

The AS error means your LG refrigerator's automatic door motor is operating but the reed switch — the sensor that detects whether the door is in the correct position — is showing an open state when it should be closed. This code may also appear as L AS for the left door or r AS for the right door depending on the model. The reed switch and door motor work together to confirm the door has reached its intended position. When the switch cannot confirm this the refrigerator displays this error. There are no user steps to resolve this and the unit requires a professional repair service.
