Error code SY CF
Appliance Refrigerator
Quick answer

SY CF shows up on Kenmore French-door refrigerators beginning 253.7031 when the control board and user interface stop communicating.

Model compatibility

Kenmore reuses codes across series and model years, so SY 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 is lost between the control board and the user interface.

Kenmore French-door refrigerators beginning 253.7031 show SY CF when the user interface and the electronic control board stop exchanging signals.

Owner-level guidance

Only two things are asked of the owner: disconnect the refrigerator and look at the wire harness connections running between the interface and the control board. They are shared with SY CE, because both codes sit in a single manual entry.

Technician-level work

With sound connections, the manual swaps the control board. If SY CF is still displayed after that, the user interface is the next part.
