Blown internal fuse on main PCB, Faulty power cord, Failed main control board power supply, Open thermal fuse on transformer (if equipped)
How to Fix / Troubleshooting
Safety: Unplug the unit before opening. If you are not comfortable working with mains voltage, seek professional help.
- Verify outlet: Test the wall outlet with another device to ensure it has power.
- Inspect power cord: Check the Comfee power cord for cuts, burns, or loose prongs. Replace if damaged.
- Access main PCB: Remove the rear or side panel to expose the main control board. Look for a small glass or ceramic fuse on the board.
- Test fuse: Use a multimeter to check continuity across the fuse. If open, replace with the same rating. If it blows again immediately, there is a deeper fault.
- Board inspection: Look for burnt components or bulging capacitors. If present, replace the main control board.
