Frigidaire Refrigerator Error Code SY CE

SY CE indicates a communication failure between the main control board and the user interface board on your Frigidaire refrigerator. This fault is detected after a Power On Reset (POR) event when the two boards fail to establish a proper communication link. The problem can stem from loose wiring connectors, damaged wiring, or a failed control board.

Unplugging the refrigerator for several minutes and restoring power performs a Power On Reset and may temporarily clear the code if the communication failure was caused by a transient power event. However, if the underlying cause is a loose connector, damaged wire, or failed board, the SY CE code will return once the reset cycle completes and the boards attempt to communicate again.

Repair costs vary depending on the root cause. If the fix is simply reseating a wiring connector, the cost may only involve a service call fee, typically in the range of $75 to $150. If a user interface board or main control board requires replacement, parts and labor combined can range from $150 to $400 or more depending on the specific model and local labor rates.

A homeowner comfortable with basic appliance repair can start by unplugging the refrigerator, locating the wiring connectors at J6 and J9A, and verifying they are fully seated and free of corrosion. If the connectors look fine and the error returns after restoring power, diagnosing and replacing a failed control board typically requires more technical experience and may be best handled by a qualified technician.

When SY CE is active, the refrigerator may not respond correctly to user inputs, and the control system may not operate normally. Food safety could be at risk if cooling functions are disrupted. It is best to address the error promptly and monitor food temperatures closely until the fault is resolved.
