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

1. undefined: Check for a loose or disconnected connector between Main PCB and the refrigerator 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 20-19. If resistance is 0 ohm (shorted), replace the sensor. 4. undefined: If resistance is open/infinite, go to step 6. 5. undefined: Compare resistance against the temperature table: 23°F/-5°C=38k, 32°F/0°C=30k, 41°F/5°C=24k, 50°F/10°C=19.5k, 59°F/15°C=16k. If value is out of range, replace the sensor. 6. undefined: If resistance is normal, check the sensor connection harness. If harness is normal, replace the refrigerator main PCB.

How to Fix

1
Check for a loose or disconnected connector between Main PCB and the refrigerator 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 20-19. If resistance is 0 ohm (shorted), replace the sensor.
4
If resistance is open/infinite, go to step 6.
5
Compare resistance against the temperature table: 23°F/-5°C=38k, 32°F/0°C=30k, 41°F/5°C=24k, 50°F/10°C=19.5k, 59°F/15°C=16k. If value is out of range, replace the sensor.
6
If resistance is normal, check the sensor connection harness. If harness is normal, replace the refrigerator main PCB.
