How to Fix / Troubleshooting

Safety: Disconnect power before accessing internal components.

Steps to handle F1:

  • Power reset: Unplug the unit for at least 15 minutes to fully discharge the control board, then plug back in.
  • Surge protection: If F1 occurred after a storm or power event, consider using a surge protector in the future.
  • Board inspection: Remove the rear or side panel to access the main control board. Look for burn marks, bulging capacitors, or other visible damage.
  • Replace main control board: F1 typically indicates a non-recoverable board fault. Order the correct main control board for your Black+Decker model and swap it, transferring all connectors one by one to the new board.
  • Professional help: If you are not comfortable replacing the board, contact an authorized service center.
