SY CE
Frigidaire Refrigerator
Severity: ModerateWhat Does This Error Mean?
SY CE means your Frigidaire refrigerator's control boards have lost communication. One board controls the display, and another controls the cooling systems. When they stop talking to each other, SY CE appears.
Affected Models
- Frigidaire FFSS2615TS
- Frigidaire FRSS2623AS
- Frigidaire Gallery FGHS2631PF
- Frigidaire Professional FPHS2687KF
Common Causes
- Loose or damaged wire harness connecting the two control boards
- Power surge or voltage spike that disrupted board communication
- Main control board has developed a fault or failure
- User interface board (the display panel) has failed
- Moisture or condensation causing a short in the wiring
How to Fix It
-
Unplug the refrigerator for 5 minutes, then plug it back in.
A power reset often clears temporary communication glitches between the boards.
-
Check that the power outlet is providing stable voltage.
Use a surge protector — voltage spikes are a common trigger for SY CE.
-
If the error returns, unplug the fridge again and pull it away from the wall.
You'll need access to the back of the unit to inspect the wiring.
-
Visually inspect the wire harness at the back of the fridge for damage or loose connectors.
If you see a disconnected plug or a pinched wire, that may be the cause.
-
If wiring looks fine and the error persists, call a technician for board diagnostics.
Either the main board or display board likely needs replacing — this is not a DIY repair.
When to Call a Professional
Control board replacement requires a technician with the right diagnostic tools. Incorrect board installation can permanently damage your refrigerator.
Frequently Asked Questions
Does SY CE mean my refrigerator is broken?
Not necessarily — sometimes it's just a temporary glitch. A power reset fixes it for many people. If it keeps coming back, a control board has likely failed.
Can a power surge cause SY CE?
Yes, power surges are one of the most common causes. Plug your fridge into a surge protector to prevent this in the future. A surge can damage both control boards at the same time.
How much does a control board replacement cost?
A replacement control board typically costs $150–$350 for the part alone. Labor adds another $100–$200 depending on your area. Get a quote before deciding whether to repair or replace the fridge.
