Possible Causes

Failed temperature sensor on motor control board, Faulty motor control board, Poor board mounting causing overheating

How to Fix / Troubleshooting

Safety first: Disconnect power before servicing electronics.

  • Inspect motor control board: Remove the board and look for an onboard temperature sensor (often a small thermistor). If physically damaged, replace the board.
  • Check mounting and airflow: Ensure the board is mounted correctly with any heat sinks in place and that airflow is not obstructed.
  • Replace motor control board: If E5B persists and no external cause is found, replace the motor control board with the correct Frigidaire part.
  • Verify with test cycle: Reassemble and run a full wash to confirm normal operation and that E5B is cleared.
