What Is Whirlpool Refrigerator Error Code SY CE?
If your refrigerator display shows SY CE, it indicates a communication error between the main control board and the user interface (display board).
In simple terms, the refrigerator’s internal electronics are not communicating properly. When the control boards cannot exchange signals, the appliance triggers the SY CE error code.
This issue can affect normal refrigerator operations, including temperature control and display functions.
Main Causes of the SY CE Error
1. Loose Wiring Connections
One of the most common causes is loose or disconnected wiring between the control board and the display panel.
Even a slightly loose connector can interrupt communication.
2. Faulty User Interface Board
The display control board may fail over time. When it stops sending signals to the main control board, the refrigerator shows the SY CE code.
3. Defective Main Control Board
The main control board manages most refrigerator functions. If it cannot communicate with the display panel, the error appears.
4. Electrical Power Fluctuations
Sudden power interruptions or voltage fluctuations can disrupt communication between electronic components.
Symptoms That May Appear With This Error
When the SY CE code appears, you may notice:
Refrigerator display not responding
Temperature settings not changing
Refrigerator beeping repeatedly
Some functions stopping unexpectedly

Reset the Refrigerator
Sometimes the problem is a temporary electronic glitch.
Steps:
Unplug the refrigerator from the power outlet.
