LG Refrigerator Er rF Error Code
Refrigerator fan is not running properly. Here is what it means and how to clear it, easiest fix first.
The fan that circulates cold air in the fresh food section is not working as expected. Frost around the fan can cause it, and so can a failing fan motor.
Also shown as E rF.
How to fix LG Er rF
Reset the power
Unplug the refrigerator or switch off its breaker, wait about 5 minutes, then restore power.
Defrost if the code returns
Move food to a cooler, empty the ice bin and lay towels on the floor. Unplug the fridge and leave the doors open for at least 24 hours so any frost melts naturally. Do not use heat sources or sharp tools to speed it up.
Dry and restart
Wipe the interior dry, plug the fridge back in and give it 24 to 48 hours to reach normal temperatures before fully restocking.
When to call a technician
If Er rF comes back after a reset and a full defrost, request service to test the refrigerator fan motor.

Frequently asked questions
What does Er rF mean on a LG refrigerator?
The fan that circulates cold air in the fresh food section is not working as expected. Frost around the fan can cause it, and so can a failing fan motor.
Can I fix LG Er rF myself?
Often. The first steps above are safe checks a homeowner can do. If they don't clear Er rF, the cause is likely a worn part that needs replacing.
What if Er rF keeps coming back?
A code that returns after a reset and the checks above usually means a part is wearing out. Note when Er rF appears (which cycle, how often) and have your model number ready; it helps a technician bring the right part on the first visit.
