Error code CF
Appliance Refrigerator
Quick answer

CF on a Kenmore 106-prefix refrigerator means the main control board and the user interface control have lost communication.

Model compatibility

Kenmore reuses codes across series and model years, so CF may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.

Plain language

What this code means

Communication failure between the main control board and the user interface control.

CF appears on the freezer display of a Kenmore refrigerator with a model number starting 106. It means the main control board and the user interface control are not communicating.

What the manual says to do

  1. Disconnect the refrigerator from power.
  2. Inspect the harness plugs at the user interface control and at the main control board. Loose wires go back on.
  3. Good connections lead to a replacement user interface control.
  4. Replace the main control board if CF is still there afterwards.
