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

1. undefined: Check for a loose connection between Main PCB and sensor at CON4 pins 18-17. 2. undefined: If connector is disconnected or loose, reconnect or repair the connector. 3. undefined: Check sensor resistance at CON4 pins 18-17. If resistance reads 0 ohm (sensor short), replace the sensor. 4. undefined: Check sensor resistance again. If resistance reads OL/infinity (sensor open), replace the sensor. 5. undefined: If resistance reads short or open, replace sensor. If resistance is normal, check temperature vs. resistance table (e.g., at -22F/-30C expect 40k ohm). 6. undefined: If temperature vs. resistance correlation is correct (no problem), explain to customer — refrigerator is operating normally. 7. undefined: Check the sensor connection physically. If connection is normal but problem persists, replace the refrigerator main PCB.

How to Fix

1
Check for a loose connection between Main PCB and sensor at CON4 pins 18-17.
2
If connector is disconnected or loose, reconnect or repair the connector.
3
Check sensor resistance at CON4 pins 18-17. If resistance reads 0 ohm (sensor short), replace the sensor.
4
Check sensor resistance again. If resistance reads OL/infinity (sensor open), replace the sensor.
5
If resistance reads short or open, replace sensor. If resistance is normal, check temperature vs. resistance table (e.g., at -22F/-30C expect 40k ohm).
6
If temperature vs. resistance correlation is correct (no problem), explain to customer — refrigerator is operating normally.
7
Check the sensor connection physically. If connection is normal but problem persists, replace the refrigerator main PCB.
