Fridge Acting Up? Here’s How to Check Error Codes on an LG Refrigerator.
Your LG refrigerator just stopped cooling, beeping, or flashing random letters on the display. Now you’re asking yourself, “What does this code even mean—and what do I do about it?” You’re not alone. LG refrigerators are smart appliances, and when something goes wrong, they try to tell you.
In this guide, I’ll show you how to check error codes on an LG refrigerator, what those codes mean, and how to know when it’s time to call in a pro.
LG error codes usually display right on the control panel or via blinking LED patterns.
You can manually check codes using button sequences on some models.
Error codes indicate issues like cooling problems, sensor failures, or fan malfunctions.
Knowing the code can save time—and avoid unnecessary repairs.
Appliance GrandMasters services LG refrigerators in Greenville SC and Asheville NC.
At Appliance GrandMasters, we’ve diagnosed hundreds of LG refrigerators across Greenville SC and Asheville NC just by checking the error codes. These codes are your fridge’s way of saying, “Hey, I need help.” Ignoring them can lead to bigger breakdowns.
Whether it’s a simple door sensor issue or a failing compressor, getting ahead of the problem starts with reading the code correctly.
Most modern LG refrigerators will show error codes like “ER IF” or “F dH” on the display screen.
Where to check:
On French door models: check the top-right display panel
On side-by-sides: check the LED screen above the ice/water dispenser
If you see a code blinking, don’t unplug the fridge yet—write it down first.
Want to troubleshoot your refrigerator? Follow this guide for homeowners we’ve prepared.
Most LG fridge error codes follow a two-letter pattern, often starting with:
ER (Error)
F (Freezer-related)
r (Refrigerator-related)
dH (Defrost Heater)
Example: ER IF = Error with Ice Fan
If your LG model doesn’t display codes automatically, you may need to enter diagnostic mode.
To activate:
Press and hold the Freezer and Express Freeze buttons at the same time
Hold for 3–5 seconds
Display will flash the current error code
⚠️ Only works on select models. Refer to your user manual to confirm compatibility.
ER IF
What it means: Ice fan not working
What to do: Check for ice buildup; defrost the unit
F dH
What it means: Defrost heater not heating properly
What to do: Needs professional diagnosis
ER FS
What it means: Freezer sensor issue
What to do: Check sensor wiring or replace sensor
r dS
What it means: Refrigerator defrost sensor issue
What to do: Could be a faulty sensor or control board
ER CO
What it means: Communication error with main board
What to do: Requires a tech to inspect board connections
FF

Note: Unplugging the fridge may clear the code temporarily but doesn’t fix the underlying issue.
Unplug the refrigerator for 30 seconds, then plug it back in.
Wait for the display to reinitialize.
If the error code returns—it’s not a fluke.
If the same code shows up twice in 48 hours
If the fridge stops cooling, leaks, or won’t power on
If you hear clicking or buzzing noises

A: It means the ice fan isn’t working. It could be iced over or burned out.
Q: Can I reset an LG refrigerator error code myself?
A: You can try unplugging it for 30 seconds. If the code returns, the issue remains.
Q: Why does my LG fridge keep flashing dH?
A: It’s a defrost heater issue. Could mean a sensor, fuse, or heater coil has failed.

A: Some codes are harmless, but others (like cooling or fan failures) can ruin your food. Best to get it checked.
