Possible Causes

Blown internal fuse on control board, Faulty power cord, Failed main control board, Defective power switch

How to Fix / Troubleshooting

Safety: Unplug the unit before opening. If you are not comfortable working with mains voltage, seek professional help.

Steps:

  • Outlet check: Plug a lamp or other device into the same outlet to confirm it has power.
  • Power cord inspection: Examine the Sunbeam power cord for cuts, kinks, or burn marks. Replace the cord if damaged.
  • Check power switch: Ensure the power button is not stuck and that it clicks normally.
  • Access control board: Remove the rear or side panel to expose the main control board. Look for an onboard fuse (glass or ceramic).
  • Test/replace fuse: With a multimeter, check continuity of the fuse. If blown, replace with the same type and rating. If it blows again immediately, there is a deeper electrical fault.
  • Board inspection: Look for burnt components or tracks on the control board. If present, replace the main control board.
