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

1. undefined: Check for loose or disconnected connector between Main PCB and freezer sensor at CON8. 2. undefined: If connector is loose or disconnected: reconnect or repair the connector and retest. 3. undefined: Measure sensor resistance at CON8 pins 22 to 21. Expected values: -22°F(-30°C)=40kΩ, -13°F(-25°C)=30kΩ, -4°F(-20°C)=23kΩ, 5°F(-15°C)=17kΩ, 14°F(-10°C)=13kΩ, 23°F(-5°C)=10kΩ, 32°F(0°C)=8kΩ. 4. undefined: If resistance reads 0Ω (short): replace the freezer sensor. 5. undefined: If resistance reads OL/infinite (open): check sensor connection.

How to Fix

1
Check for loose or disconnected connector between Main PCB and freezer sensor at CON8.
2
If connector is loose or disconnected: reconnect or repair the connector and retest.
3
Measure sensor resistance at CON8 pins 22 to 21. Expected values: -22°F(-30°C)=40kΩ, -13°F(-25°C)=30kΩ, -4°F(-20°C)=23kΩ, 5°F(-15°C)=17kΩ, 14°F(-10°C)=13kΩ, 23°F(-5°C)=10kΩ, 32°F(0°C)=8kΩ.
4
If resistance reads 0Ω (short): replace the freezer sensor.
5
If resistance reads OL/infinite (open): check sensor connection. If connection is normal, replace the refrigerator PCB.
6
If sensor connection is abnormal: reconnect or repair the connector.
7
If resistance is within normal range but error persists: explain situation to customer; intermittent fault possible.
