How to fix it

  1. Unplug the dryer for 10 minutes and restore power; if error persists, proceed.
  2. Unplug again and open the control panel.
  3. Inspect the main control board for burn marks, swollen capacitors, or corrosion.
  4. Before condemning the board, check the heater element and motor for shorts that may have damaged board outputs.
  5. If no external faults found, replace the main control board.
  6. Configure or pair the new board per service literature (model-specific).
  7. Reassemble and run a full diagnostic cycle to confirm normal operation.
  8. Consider installing a surge protector to prevent recurrence.
