Possible Causes

Loose wiring harness between UI and main control, Corroded or damaged connector at control board, Failed user interface control panel, Failed main control board

How to Fix / Troubleshooting

Safety: Always disconnect power before accessing control boards or removing panels.

  • Power reset: Unplug the refrigerator for 5–10 minutes, then plug it back in. Observe if the SY CE code returns.
  • Check display harness (if accessible): Remove the control panel cover (usually at the top of the fresh food section or on the dispenser) and verify the ribbon cable or harness is fully seated.
  • Inspect main control connections: Access the main control board (often at the rear, behind a metal cover). With power disconnected, check that all harnesses are firmly plugged in and not damaged.

If the code persists after reseating connectors, either the user interface or the main control board is defective. Component-level diagnosis is best left to a technician with access to Maytag service documentation.
