How do I fix error code E FS on my LG LF30S8210S?

1. undefined: Check for a loose or disconnected connector between Main PCB and the freezer sensor at CON8. 2. undefined: If connector is disconnected or loose, reconnect or repair the connector. 3. undefined: With power off, measure sensor resistance at CON8 pins 22-21. If resistance is 0 ohm (shorted), replace the sensor. 4. undefined: If resistance is open/infinite (OL), go to step 6. 5. undefined: If resistance is a finite non-zero value, compare against the temperature-resistance table: -22°F/-30°C=40k, -13°F/-25°C=30k, -4°F/-20°C=23k, 5°F/-15°C=17k, 14°F/-10°C=13k, 23°F/-5°C=10k, 32°F/0°C=8k. If value is out of range for the ambient temperature, replace sensor. 6. undefined: If resistance is normal for temperature, check the wiring harness integrity between sensor and PCB. If harness is good, replace the main PCB.

How to Fix

1
Check for a loose or disconnected connector between Main PCB and the freezer sensor at CON8.
2
If connector is disconnected or loose, reconnect or repair the connector.
3
With power off, measure sensor resistance at CON8 pins 22-21. If resistance is 0 ohm (shorted), replace the sensor.
4
If resistance is open/infinite (OL), go to step 6.
5
If resistance is a finite non-zero value, compare against the temperature-resistance table: -22°F/-30°C=40k, -13°F/-25°C=30k, -4°F/-20°C=23k, 5°F/-15°C=17k, 14°F/-10°C=13k, 23°F/-5°C=10k, 32°F/0°C=8k. If value is out of range for the ambient temperature, replace sensor.
6
If resistance is normal for temperature, check the wiring harness integrity between sensor and PCB. If harness is good, replace the main PCB.
