How do I fix error code E FS 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 Blue/White to Blue/White wires 4. undefined: If 0 Ohm (short circuit): replace the freezer sensor 5. undefined: If open circuit (infinite resistance): replace the refrigerator 6. undefined: If reading is in normal range, check temperature: at -22F/-30C expect 40.5-38.5 kOhm; at -13F/-25C expect 30.5-28.5 kOhm; at -4F/-20C expect 23-21.5 kOhm; at 5F/-15C expect 17.5-16.5 kOhm; at 14F/-10C expect 13.5-12.5 kOhm; at 23F/-5C expect 10.5-9.5 kOhm; at 32F/0C expect 8-7.5 kOhm

Error Code E FS

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

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

Freezer Sensor Error

Moderate

Address soon - your appliance may not work properly

What This Means

Short circuit on freezer sensor wiring; Open/disconnected freezer 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 Blue/White to Blue/White wires
4
If 0 Ohm (short circuit): replace the freezer sensor
5
If open circuit (infinite resistance): replace the refrigerator
6
If reading is in normal range, check temperature: at -22F/-30C expect 40.5-38.5 kOhm; at -13F/-25C expect 30.5-28.5 kOhm; at -4F/-20C expect 23-21.5 kOhm; at 5F/-15C expect 17.5-16.5 kOhm; at 14F/-10C expect 13.5-12.5 kOhm; at 23F/-5C expect 10.5-9.5 kOhm; at 32F/0C expect 8-7.5 kOhm
