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

1. undefined: Check connection between Main PCB, defrost controller, and sensor at CON5 pins 10–9; reconnect if loose. 2. undefined: Measure sensor resistance at CON5 pins 10–9: 23°F/-5°C = 38kΩ, 32°F/0°C = 30kΩ, 41°F/5°C = 24kΩ, 50°F/10°C = 19.5kΩ, 59°F/15°C = 16kΩ. 3. undefined: If resistance is 0Ω (shorted) or OL/∞ (open): replace defrost sensor. 4. undefined: If resistance is normal: replace Main PCB. 5. undefined: If defrost sensor resistance is within spec and error persists: explain to customer.

How to Fix

1
Check connection between Main PCB, defrost controller, and sensor at CON5 pins 10–9; reconnect if loose.
2
Measure sensor resistance at CON5 pins 10–9: 23°F/-5°C = 38kΩ, 32°F/0°C = 30kΩ, 41°F/5°C = 24kΩ, 50°F/10°C = 19.5kΩ, 59°F/15°C = 16kΩ.
3
If resistance is 0Ω (shorted) or OL/∞ (open): replace defrost sensor.
4
If resistance is normal: replace Main PCB.
5
If defrost sensor resistance is within spec and error persists: explain to customer.
