LG FFFreezer evaporator fan not running normally (short form of Er FF)

An LG FF (or Er FF) is a freezer evaporator fan fault — the freezer fan isn't running normally, usually iced over or a failed fan motor. The freezer warms and cooling drops. Thaw it out first (force-defrost or unplug 24 hours); if the fan's still dead or grinding after the ice clears, replace the freezer fan motor.

🔧 From our repair bench: FF is a fan jammed in frost or burned out — thaw first, order the motor only if it's still dead.

🐜 Straight talk: this points you at the likely cause — it's not a guarantee, and every machine is different. Cut the power (and shut off gas or water) before you touch anything, test to confirm the part is actually bad before you buy, and if it's beyond you, get a pro. No shame in that.

Can you fix it yourself?

Safe to Try · Know the Risk · Call a Pro

General guidance, not professional advice. Always unplug the appliance (or shut off the gas/water) before you check anything. If it feels beyond you, that's exactly when to get a pro.

✅ Safe to try yourself

  • Listen at the freezer back panel for a dead or grinding fan.
  • Check for frost buildup jamming the fan.
  • Force-defrost or unplug 24–48h and see if the fan frees.

⚠️ Doable — know the risk

  • Freezer fan motor replacement — moderate; unplug, remove the back panel, melt ice first.

🛑 Call a pro — don't touch this

  • A repeating defrost failure that keeps re-icing the fan.
