Some of the Most Common LG Refrigerator Error Codes

French door, side-by-side and bottom freezer models have nearly identical diagnostic codes. If you have a top freezer, you’ll need to check your owner’s manual for directions on how to diagnose problems with your model.

FS

This error code means there’s a problem with your freezer sensor. The sensor likely needs to be replaced.

rS

This error code means the refrigerator sensor is malfunctioning. You probably need to replace the sensor.

dS

This error code means your defrosting sensor isn’t working properly. Depending on your model, there could be variants of this error code that include extra letters before the “dS.”

EID

This error code means a sensor in your ice maker isn’t working. You may need to replace it.

dH

You may see this error code if you attempted to defrost your refrigerator and it took too long to return to the correct temperature. Unplugging your fridge for a few minutes often resolves it.

FF

This error code means something’s wrong with your freezer fan. To make sure that the issue isn’t simply due to frost buildup, leave your freezer open for at least 8 hours, wipe it down and let it run for a day or two. If you still see the error code, the fan may be broken.

F1

This error code indicates something is wrong with your ice maker fan. The solution is the same as troubleshooting a freezer fan issue.

C1

This error code only appears when your fridge is experiencing an internal communication error. You need a technician to diagnose this problem.

CO

This error code indicates a problem with your refrigerator’s control panel. You need a technician to repair this issue.

IS

This error code appears when your ice maker’s fan motor isn’t working. It could also indicate a problem with the sensor.

iT

LG doesn’t say much about this error code except that it means your ice maker is defective.

rF

This error code may mean your refrigerator needs a new fan motor. LG recommends leaving your fridge open for 8 hours, wiping it down and then letting it run for at least a day to see if the code goes away. If not, you need a new fan motor.

gF

This error code means something’s wrong with your water line. Your water pressure may be low, or your ice maker is overflowing with water.

Sb

This error code simply means your refrigerator is in Sabbath mode. If you don’t want it to enter this mode, hold the Wi-Fi and freezer buttons for three seconds.

CL

This error code means you may have a refrigerant leak. You need to locate the source of the leak and refill your refrigerant.

22

This error code means something is wrong with your refrigerator’s compressor relay. It’s best to call a professional for help.

When to Call a Professional

Some error codes indicate that the only solution is to call a technician. In other instances, you may wish to call a professional if you attempted the suggested solution and are still experiencing the same issues.
