Kenmore Refrigerator Error Code Er CE — Communication Error
What this means
The Er CE error code on Kenmore Elite refrigerators indicates a communication failure between the display panel (user interface board) and the main control board. This can be caused by a loose wire harness, a power surge that damaged one of the boards, or a failed ribbon cable. The display may be blank, show garbled text, or be unresponsive to touch/button presses.
Alternate codes: ErCE
Step-by-step fix
3 stepsPower cycle the refrigerator
Unplug the unit for 5 minutes, then restore power. Check if the display initializes properly and the error clears.
A power surge can temporarily disrupt board communication. A reset may be all that is needed.
Check the display panel wire harness
Remove the display panel from the refrigerator door (usually held by clips or screws). Check the wire harness or ribbon cable connecting the display to the door wiring. Disconnect and reseat firmly.
Also check the hinge area where the door wire harness passes through — repeated door opening can stress these wires.
Replace the display panel or main control board
If the harness is intact and the error persists, one of the boards has failed. Replace the display panel first (more common failure). If the code continues, replace the main control board.
The display panel for Kenmore Elite models is usually available through the same manufacturer that makes the OEM unit (often LG).
When to call a professional
If both boards have been replaced and the error persists, the door wire harness may need replacement — a repair that requires routing wires through the hinge mechanism.
