LG CFCondenser fan not running normally (Er CF)

An LG CF (or Er CF) is a condenser fan fault — the fan that cools the compressor at the bottom-back isn't running normally. When it seizes or clogs with dust and pet hair, the system overheats and cooling drops. Clean the fan and coils first (free); if the fan is still dead or noisy, replace the condenser fan motor.

🔧 From our repair bench: CF often clears with a vacuum — the condenser fan gets choked with dust and pet hair down at the bottom-back.

🐜 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

  • Pull the fridge out and vacuum the condenser fan and coils at the bottom-back.
  • Spin the fan by hand (power off) — it should turn freely.
  • Clear anything blocking the fan (a fallen object, thick dust mat).

⚠️ Doable — know the risk

  • Condenser fan motor replacement — moderate; unplug, remove the lower-back cover.

🛑 Call a pro — don't touch this

  • A compressor or sealed-system fault behind the fan.
