Possible Causes

Loose ribbon cable between UI and main board, Failed display/control panel, Oxidized connectors, Faulty main control board communication circuit

How to Fix / Troubleshooting

Safety first: Disconnect power before removing the control panel or display housing.

Steps:

  • Remove the control panel trim to access the user interface board.
  • Check the ribbon cable or harness between the UI and main control board for secure seating.
  • Inspect connectors for corrosion or bent pins.
  • Look for signs of moisture damage on the UI board.

Corrective action: Reseat or replace the ribbon cable if damaged. If E13 persists, replace the user interface board. If a new UI does not resolve the error, the main control board may be defective.
