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

1. undefined: Check for loose connection at CON5 on main PCB 2. undefined: Unplug connector from CON5 3. undefined: Check resistance between White to White wires 4. undefined: If 0 Ohm (short circuit): replace the refrigerator sensor 5. undefined: If open circuit (infinite resistance): replace the refrigerator 6. undefined: If reading is in normal range, check temperature: at 23F/-5C expect 38.5-36.5 kOhm; at 32F/0C expect 30.5-29.5 kOhm; at 41F/5C expect 24.5-23.5 kOhm; at 50F/10C expect 20-19 kOhm; at 59F/15C expect 16-15.5 kOhm

Error Code E rS

Q: What does error code E rS mean on a LG refrigerators?

Refrigerator Sensor Error Short circuit on refrigerator sensor wiring; Open/disconnected refrigerator sensor wiring; Loose connection at CON5 on main PCB

Refrigerator Sensor Error

Moderate

Address soon - your appliance may not work properly

What This Means

Short circuit on refrigerator sensor wiring; Open/disconnected refrigerator sensor wiring; Loose connection at CON5 on main PCB

How to Fix

1
Check for loose connection at CON5 on main PCB
2
Unplug connector from CON5
3
Check resistance between White to White wires
4
If 0 Ohm (short circuit): replace the refrigerator sensor
5
If open circuit (infinite resistance): replace the refrigerator
6
If reading is in normal range, check temperature: at 23F/-5C expect 38.5-36.5 kOhm; at 32F/0C expect 30.5-29.5 kOhm; at 41F/5C expect 24.5-23.5 kOhm; at 50F/10C expect 20-19 kOhm; at 59F/15C expect 16-15.5 kOhm
