How to Fix / Troubleshooting

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

Steps:

  • 1. Check outlet and cord: Test the outlet with another appliance. Inspect the Daewoo power cord for damage. Replace the cord if any defects are found.
  • 2. Inspect internal fuse: Remove the rear or bottom cover to access the main PCB. Look for a glass or ceramic fuse near the mains input. Test for continuity and replace with the same rating if blown.
  • 3. Check mains connector: Ensure the wires from the cord to the PCB or terminal block are secure and not burned.
  • 4. Examine PCB: Look for obvious damage such as burnt components or cracked solder joints. If present, the board likely needs replacement.

Note: If the fuse blows again immediately after replacement, there is a short circuit that must be diagnosed before further use.
