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

1. undefined: Check for loose or disconnected connector between Main PCB and refrigerator 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 20 to 19. Expected values: 23°F(-5°C)=38kΩ, 32°F(0°C)=30kΩ, 41°F(5°C)=24kΩ, 50°F(10°C)=19.5kΩ, 59°F(15°C)=16kΩ. 4. undefined: If resistance reads 0Ω (short): replace the refrigerator sensor. 5. undefined: If resistance reads OL/infinite (open): check sensor connection. If connection is normal, replace the refrigerator. 6. undefined: If sensor connection is abnormal: reconnect or repair the connector. 7. undefined: If resistance is within normal range but error persists: explain situation to customer.

How to Fix

1
Check for loose or disconnected connector between Main PCB and refrigerator sensor at CON8.
2
If connector is loose or disconnected: reconnect or repair the connector and retest.
3
Measure sensor resistance at CON8 pins 20 to 19. Expected values: 23°F(-5°C)=38kΩ, 32°F(0°C)=30kΩ, 41°F(5°C)=24kΩ, 50°F(10°C)=19.5kΩ, 59°F(15°C)=16kΩ.
4
If resistance reads 0Ω (short): replace the refrigerator sensor.
5
If resistance reads OL/infinite (open): check sensor connection. If connection is normal, replace the refrigerator.
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.
