How do I fix error code F dS on a LG refrigerators?

1. undefined: Check for loose connection on defrost sensor connector at evaporator 2. undefined: Check wires Orange to Orange at the defrost control assembly 3. undefined: Check for loose connection at CON7 from main PCB 4. undefined: Unplug connector from CON7 and check resistance between Brown to Brown wires (pins 21-22) 5. undefined: If 0 Ohm: change the sensor 6. undefined: If open circuit: replace the refrigerator 7. undefined: If other: compare to Ref/Def temp table — 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 F dS

Q: What does error code F dS mean on a LG refrigerators?

Freezer Defrost Sensor Error Short circuit on defrost sensor; Open/disconnected defrost sensor wiring; Loose connection at CON7 (D-SENSOR pins 21-22)

Freezer Defrost Sensor Error

Moderate

Address soon - your appliance may not work properly

What This Means

Short circuit on defrost sensor; Open/disconnected defrost sensor wiring; Loose connection at CON7 (D-SENSOR pins 21-22)

How to Fix

1
Check for loose connection on defrost sensor connector at evaporator
2
Check wires Orange to Orange at the defrost control assembly
3
Check for loose connection at CON7 from main PCB
4
Unplug connector from CON7 and check resistance between Brown to Brown wires (pins 21-22)
5
If 0 Ohm: change the sensor
6
If open circuit: replace the refrigerator
7
If other: compare to Ref/Def temp table — 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
