How do I fix error code E rS on my LG LF29H8330B?

1. undefined: Check for a loose or disconnected connector between Main PCB and sensor (CON8 pins 20–19). If loose or disconnected, reconnect or repair the connector. 2. undefined: With power off, measure resistance at CON8 pins 20–19. If resistance is 0 Ω (short circuit), replace the refrigerator sensor. 3. undefined: With power off, measure resistance at CON8 pins 20–19. If resistance is infinite/open, go to step 6. 4. undefined: Compare measured resistance against the temperature/resistance table for CON8 pins 20–19. If resistance does not match expected value, replace the sensor. 5. undefined: If resistance matches the table at current ambient temperature, the sensor is functioning correctly — explain normal operation to customer. 6. undefined: Check the physical sensor connection. If the sensor connection is normal, replace the refrigerator. If sensor connection is abnormal, reconnect or repair the connector.

How to Fix

1
Check for a loose or disconnected connector between Main PCB and sensor (CON8 pins 20–19). If loose or disconnected, reconnect or repair the connector.
2
With power off, measure resistance at CON8 pins 20–19. If resistance is 0 Ω (short circuit), replace the refrigerator sensor.
3
With power off, measure resistance at CON8 pins 20–19. If resistance is infinite/open, go to step 6.
4
Compare measured resistance against the temperature/resistance table for CON8 pins 20–19. If resistance does not match expected value, replace the sensor.
5
If resistance matches the table at current ambient temperature, the sensor is functioning correctly — explain normal operation to customer.
6
Check the physical sensor connection. If the sensor connection is normal, replace the refrigerator. If sensor connection is abnormal, reconnect or repair the connector.
