Error codeSY CF

SY CF in brief
If the refrigerator is starting up and the display reads SY CF (also written SY-CF), the UI and the main control board could not talk to each other. Frigidaire lists it in service data sheets 242321500 and A01544701, which belong to the FFHN2740PS/PE and FGHG2366PF bottom-freezer ice and water models.
Steps for the owner
Know that neither sheet lists an owner check for this code.
Copy down the code exactly as the display shows it, and find the model number.
Arrange service.

SY CE: the same communication path failing after the unit has been running
Owners in San Francisco and around the Bay Area can request Frigidaire refrigerator repair on (415) 319-6371. Say that the failure happens at start up and give the model number.
Model compatibility: Frigidaire 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
SY CF is a communication failure between the user interface and the main control board on start up.
Important safety warning. Do not attempt repairs involving electrical components, gas, water lines, refrigerant or sealed systems. Unplug the appliance if it is safe to reach the outlet, and leave internal diagnostics to a qualified technician.
