Display shows ER or Err; some functions may be locked out; temperatures may not adjust.

Safety first: Unplug the refrigerator before removing the control panel. Avoid using excessive water when cleaning the UI area.

Step 1 – Check for stuck buttons:

• Press each button on the control panel individually and feel for proper travel.
• If a button feels stuck or does not click, gently clean around it with a soft cloth.
• Do not spray cleaner directly on the panel; apply to cloth first.

Step 2 – Dry out moisture:

• If the panel was recently cleaned or exposed to moisture, unplug the unit and allow the panel area to dry for several hours.
• Use a fan to circulate air around the control area.

Step 3 – Inspect and reseat UI connections:

• Remove the control panel bezel.
• Disconnect and reconnect the ribbon cable or harness to the UI board.
• Check for corrosion or damage.

Step 4 – Replace UI board if needed:

• If ER persists and buttons do not respond correctly, replace the user interface board.
• If replacing the UI does not resolve the error, the main control board may be at fault.

When to call a technician: For persistent ER codes or if you suspect board-level damage, professional diagnostics are recommended.
