What Does Error Code Er rF Mean on a LG Refrigerator?

Refrigerator fan error — fresh-food compartment fan not running.

Er rF fires when the control board stops receiving rotation feedback from the fresh-food (refrigerator) evaporator or circulation fan. The motor uses a Hall-effect sensor to report speed; when pulses stop or fall out of range, the board flags a stalled fan. Unlike Er FF, which points to a freezer fan, or defrost-related codes, Er rF isolates the fridge-compartment airflow. Frost buildup from a failing defrost cycle physically jamming the blade is the most frequent trigger.

Models affected: LG refrigerators using the Er rF fault code, including French-door and side-by-side models such as the LFXS26973S, LFXS28968S, LRFVS3006S, LMXS28626S, and LRFDS3016S
What owners report: Owners commonly report this code alongside a warm fridge but still-cold freezer, and often after a defrost problem lets ice creep onto the fan. A thaw-out sometimes clears it temporarily, but many find it returns within weeks, which usually points to the defrost system rather than the fan itself.

What Causes Error Code Er rF?

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

  1. 1
    Fan iced over from defrost system failure 40% of cases
  2. 2

  3. 3
    Fan blade obstructed or shroud shifted 15% of cases
  4. 4
    Harness/connector fault 15% of cases

How to Fix LG Refrigerator Error Code Er rF

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

    Thaw the fan

    Unplug the refrigerator and let the compartment thaw 8–24 hours (or use forced defrost mode) to free an iced fan.

  2. 2

    Check the fan blade

    Remove the interior rear panel and confirm the blade spins freely; clear obstructions and reseat the shroud.

    ⚠️ Unplug the refrigerator before removing interior panels.
  3. 3

    Replace the fan motor

    If the blade is free but the motor doesn't run when powered, replace it.

When to Call a Professional

If the fan ices over again within weeks, the defrost heater, sensor, or board needs professional diagnosis — the fan is the symptom, not the cause.

Frequently Asked Questions

Can I keep using my LG Refrigerator when error Er rF appears? +
It is not advisable. The refrigerator may still power on, but running it while Er rF is active can worsen the cooling fault or damage related parts. Treat it as a soon-as-possible repair.
What most commonly causes Er rF on a LG Refrigerator? +
Across reported LG refrigerator repairs, the most frequent is fan iced over from defrost system failure (40% of cases), fan motor failed (30%), then fan blade obstructed or shroud shifted (15%). Check them in that order before replacing any parts.
Er rF keeps coming back after a reset — what should I check next? +
A reset only clears the stored Er rF fault; if it returns, the cooling problem is still present. Move on to the physical checks — thaw the fan, then check the fan blade — 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 Er rF? +
A DIY repair typically runs $0–$60 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 Er rF? +
Er rF is documented on LG refrigerators using the Er rF fault code, including French-door and side-by-side models such as the LFXS26973S, LFXS28968S, LRFVS3006S, LMXS28626S, and LRFDS3016S. Other units sharing the same control platform can display it too, so the fixes here generally transfer across the series.
