The condenser fan that cools the compressor at the back of the fridge is not running. A failed fan motor is the most common cause, and the compressor may overheat if it is left unfixed.

Likely causes

Listed from most to least common.

  1. Condenser fan motor failed
  2. Fan blade blocked by dust, debris or an object
  3. Loose or disconnected wiring
  4. Main control board fault

How to fix the Er CF code

Unplug the refrigerator or switch it off at the breaker before removing any panel or filter.

  1. Step 1: Reset the power

    Unplug the refrigerator or switch off its breaker, wait about 5 minutes, then restore power.

  2. Step 2: Clear the back of the fridge

    With the fridge unplugged, pull it out and make sure nothing is pressed against the lower rear cover. Vacuum dust from the vents.

  3. Step 3: Watch for the code

    The code can clear after a reset but return about 3 hours later. If it does, book a service call.

You'll need: Vacuum with brush attachment, flashlight.

Parts that may need replacing

Check your model number on the label inside the door or on the back before ordering.

When to call a technician

If CF comes back after a reset, have a technician replace the condenser fan motor or check the wiring and board.

A typical repair for this code costs $150–$350 in the US, including parts and labor. Prices vary by area and model.

Models this applies to

  • French door refrigerators (LF, LR and LM series)
  • Side-by-side refrigerators (LS and LRS series)
  • InstaView Door-in-Door models
  • Linear and inverter linear compressor models

Codes can differ slightly between models. Your owner's manual is the final word and is available from LG support.

Common questions

›Why is my LG fridge buzzing with a CF code?

LG notes a buzzing or humming sound can come with this error, as the compressor runs while the fan is not moving air.

›Can I keep using the fridge with a CF error?

Only for a short time. The compressor overworks without the fan, which can lead to a much costlier repair.
