Whirlpool Refrigerator Error Code SY CE — Communication Error
What this means
The SY CE error code on Whirlpool refrigerators signals a communication failure between the main control board and the user interface (UI) board. This is distinct from the SY CF and SY EF codes and specifically relates to a data-transfer breakdown. It commonly occurs after a power surge, a loose wire harness connection, or a failed control board. This code is found on Whirlpool French Door and side-by-side models with electronic displays.
Alternate codes: SYCE, SY-CE
Step-by-step fix
3 stepsPower cycle the refrigerator
Unplug the refrigerator from the wall outlet or turn off the circuit breaker for 5 minutes, then restore power. Allow the unit to restart and check whether the SY CE code clears.
If a power surge recently occurred, this reset alone may resolve the issue.
Inspect the wire harness between boards
Remove the top grille or access the rear panel depending on your model. Locate the flat ribbon cable or wire harness connecting the UI board (behind the front display) to the main control board (usually at the rear bottom). Check for loose, pinched, or corroded connectors.
Disconnect and firmly reseat each connector. Look for any signs of rodent damage or pinched wires.
Test and replace the UI board or main control board
If the wiring is intact, the UI board behind the display panel is the more common failure point. Replace it first. If the code persists, the main control board at the rear lower section may need replacement.
Take photos of all wire connections before disconnecting anything to ensure correct reassembly.
When to call a professional
If you are uncomfortable accessing control boards or if replacing both boards does not resolve the error, contact a certified Whirlpool technician.
