Frigidaire Refrigerator Error Code SY CE — Communication Error
What this means
The SY CE error on Frigidaire refrigerators indicates a communication failure between the main control board (usually at the back or bottom of the unit) and the user interface display board (on the refrigerator door). This can be caused by a damaged wire harness (especially through the door hinge), a loose connector, a failed display board, or a failed main board.
Alternate codes: SYCE, CE
Step-by-step fix
4 stepsPower cycle the refrigerator
Unplug the refrigerator for 5 minutes, then plug it back in. A temporary communication glitch may clear with a full reset.
If the error clears but returns within hours, the communication link has an intermittent fault — usually a broken wire.
Check the wire harness at the door hinge
The communication cable runs through the top door hinge area, where it flexes with every door opening. Inspect this area for pinched, broken, or frayed wires.
This is the single most common cause of SY CE. The wire can break internally while the outer insulation appears intact.
Test continuity through the harness
Disconnect the harness at both ends (display board and main board). Test continuity through each wire individually. Any wire that reads open has a break.
Flex the harness gently while testing to catch intermittent breaks.
Replace the harness or board
If any wires are broken, replace the door harness. If the harness is fine, try the display board first (it fails more commonly than the main board). If the error persists, replace the main board.
When routing a new harness, use the strain relief clips to prevent future wire fatigue.
When to call a professional
If you have replaced the harness and one board but the error persists, professional diagnosis can prevent unnecessary parts replacement.
