How do I fix error code E FS on a LG refrigerators?

1. undefined: Check CON8 Pin 22 ~ Pin 21 for short (0 Ω) or open (infinite) resistance. Short = replace sensor; open = proceed to step 2. 2. undefined: Check that the connector between Main PCB and freezer sensor is fully seated. Reconnect or repair any loose/damaged connector. 3. undefined: With connector properly seated, measure sensor resistance at Pin 22 ~ Pin 21 and compare against temperature/resistance table (-22°F=40kΩ, -13°F=30kΩ, -4°F=23kΩ, 5°F=17kΩ, 14°F=13kΩ, 23°F=10kΩ, 32°F=8kΩ). 4. undefined: If resistance is within normal range at the current ambient temperature, the system is operating correctly — explain to customer. 5. undefined: If resistance is abnormal but connector and harness are intact, replace the freezer sensor. 6. undefined: If replacing the sensor does not resolve the error, replace the Main PCB.

How to Fix

1
Check CON8 Pin 22 ~ Pin 21 for short (0 Ω) or open (infinite) resistance. Short = replace sensor; open = proceed to step 2.
2
Check that the connector between Main PCB and freezer sensor is fully seated. Reconnect or repair any loose/damaged connector.
3
With connector properly seated, measure sensor resistance at Pin 22 ~ Pin 21 and compare against temperature/resistance table (-22°F=40kΩ, -13°F=30kΩ, -4°F=23kΩ, 5°F=17kΩ, 14°F=13kΩ, 23°F=10kΩ, 32°F=8kΩ).
4
If resistance is within normal range at the current ambient temperature, the system is operating correctly — explain to customer.
5
If resistance is abnormal but connector and harness are intact, replace the freezer sensor.
6
If replacing the sensor does not resolve the error, replace the Main PCB.
