Error code CF
Appliance Refrigerator
Quick answer

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

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.

What CF reports

A CF on the freezer display of a Kenmore 106-prefix refrigerator tells you the user interface control and the main control board have lost their link.

Manual order of work

Disconnect the refrigerator from power. Inspect the harness connections at both ends, the user interface control and the main control board, and push loose wires back on. When the connections are good, a new user interface control comes next. If CF persists after that, the main control board is replaced.

Compare with

C (thermistor failure) and d (stuck air damper) are separate displays on the same model.
