What Does Error Code 1F Mean on a LG Refrigerator?

Freezer (ice room) fan fault — icing fan circuit failure.

The 1F code indicates the control board is monitoring the ice-room fan circuit and no rotation feedback is being received. This fan draws cold air into the door-mounted icing compartment, so when it stalls the board flags the fault, ice output drops, and cubes may fuse together. Unlike broader cooling codes, 1F is isolated to the icing fan rather than the main evaporator fan or sealed system, and a frost-seized blade is the most frequent trigger.

Models affected: LG French-door and side-by-side refrigerators with door-mounted (in-door) ice makers, including models such as LFXS26973S, LFXS28968S, LMXS28626S, LRFVS3006S, and LRFDS3016S
What owners report: Owners commonly report this code after ice production slows or cubes clump, and many find the small fan is simply locked in frost. A manual thaw or forced defrost often clears it temporarily; if frost keeps returning, a leaking duct gasket is usually the underlying culprit.

What Causes Error Code 1F?

Here are the most common causes in order of frequency. Start with the most likely cause before moving to the next:

  1. 1
    Ice room fan frozen in frost 45% of cases
  2. 2
    Fan motor failed 30% of cases
  3. 3
    Duct gasket leak letting moist air frost the compartment 15% of cases
  4. 4
    Wiring fault 10% of cases

How to Fix LG Refrigerator Error Code 1F

🔧🔧 Moderate DIY Est. time: 30–60 min
⚡ Safety first: Unplug the appliance before opening any panels or touching internal components.
  1. 1

    Defrost the ice compartment

    Unplug the unit and thaw the ice room (door open, ice bin out) or run forced defrost from the test mode.

  2. 2

    Check the fan

    With power off, remove the ice maker and confirm the small fan blade turns freely; clear ice and reseat the duct gaskets.

    ⚠️ Unplug the refrigerator before removing the ice maker assembly.
  3. 3

    Replace the ice room fan

    If thawed and free but not running, replace the fan motor.

How to Reset Error Code 1F

After thawing or repair, plug back in; the code clears when the fan reports rotation.

Note: If the error returns after resetting, the underlying issue has not been resolved. Work through the fix steps above.

When to Call a Professional

Recurring frost in the ice room means an air-leak or defrost defect that fan swaps won't fix — call a technician.

Average professional repair cost for this issue: $150–$300

Frequently Asked Questions

Can I keep using my LG Refrigerator when error 1F appears? +
You often can for a cycle or two, but the ice-maker issue behind 1F will keep interrupting normal operation until it is fixed. Plan the repair rather than ignoring the code.
What most commonly causes 1F on a LG Refrigerator? +
Across reported LG refrigerator repairs, the most frequent is ice room fan frozen in frost (45% of cases), fan motor failed (30%), then duct gasket leak letting moist air frost the compartment (15%). Check them in that order before replacing any parts.
1F keeps coming back after a reset — what should I check next? +
A reset only clears the stored 1F fault; if it returns, the ice-maker problem is still present. Move on to the physical checks — defrost the ice compartment, then check the fan — since the code will reappear until the root cause is resolved. This is a moderate job — a multimeter and some disassembly are usually involved.
How much does it cost to fix LG Refrigerator error 1F? +
A DIY repair typically runs $0–$55 in parts, versus $150–$300 for a professional service call, so handling it yourself saves around $150. Expect the work to take roughly 30–60 minutes.
Which LG Refrigerator models show error 1F? +
1F is documented on LG French-door and side-by-side refrigerators with door-mounted (in-door) ice makers, including models such as LFXS26973S, LFXS28968S, LMXS28626S, LRFVS3006S, and LRFDS3016S. Other units sharing the same control platform can display it too, so the fixes here generally transfer across the series.
