What Our Customers Say
"I am so happy with the services provided by TruePro Home Services! I have a very old oven that I truly believed would need to be replaced. But, Yury came on time, diagnosed the issues, and had the parts with him to do the repair the same day. My oven is now in perfect working order. Highly recommend!"

"Our LG Front Loading washer wasn't draining. I contacted Simon the next day. He had the part on his truck and came by within 30 minutes, and had it up and running super fast! Thank you Simon for your punctuality, honesty and great value. See you next time!"

What Error Code Er IF Means
The Er IF code indicates the ice maker fan motor is not spinning or the control board is not receiving a speed feedback signal from it. This fan circulates cold air around the ice maker compartment to maintain proper freezing temperatures. Without it, ice production slows dramatically or stops entirely. The rest of the freezer and fridge continue to function normally in most cases.
Common Causes
Failed ice maker fan motor
The motor windings burn out. The motor draws power but produces no rotation. Fan motor lifespan varies, but 6-10 years is typical in LG refrigerators.
Ice buildup jamming the fan blade
Water drips or frost accumulation around the ice maker fan housing lock the blade in place. The motor stalls and trips the error.
Disconnected or damaged wiring
The fan motor wire harness gets caught on moving parts or worn through where it passes through compartment walls. A broken wire produces the error.
Faulty control board signal circuit
The fan motor speed sensing circuit on the main board fails. The fan spins, but the board does not detect it. This is uncommon.
How to Fix It
- 1
Reset the refrigerator
Unplug the refrigerator for 5 minutes. Plug it back in. If Er IF clears and ice production resumes within 24 hours, the issue was a temporary stall or glitch.
- 2
Access the ice maker fan
Open the freezer. Locate the ice maker compartment (usually upper-left in LG French-door models). Remove the ice bucket by pulling it straight out. Remove the ice maker housing cover (Phillips screws or clips). The fan is behind or adjacent to the ice maker assembly.
Unplug the refrigerator before removing any housing covers.

Check for ice buildup around the fan
Inspect the fan blade and surrounding housing for frost or ice. If ice is present, use a hair dryer on low heat to melt it, keeping the dryer 6 inches from plastic components. Clear all ice and test the fan by restoring power briefly.

Test the fan motor
Disconnect the fan motor's wire harness. Set a multimeter to the 200-ohm range. Measure resistance across the motor terminals. Expect 50-200 ohms for a working motor. OL or 0 ohms means the motor is dead. Order a replacement ice maker fan motor for your LG model.
Make sure the unit is unplugged before disconnecting and testing the motor.

Inspect wiring connections
Follow the wire harness from the fan motor to the main connector. Look for pinched, cracked, or disconnected wires. Reconnect any loose connectors. Repair broken wires with butt connectors rated for freezer temperatures.
When to Call a Professional
If the fan motor tests bad or ice buildup recurs after clearing it, a technician should diagnose the root cause. Recurring ice around the fan often points to a defrost issue or a leaking water inlet.
