How to Fix / Troubleshooting
Safety: Unplug from mains before opening the housing. Only work on live circuits if you are qualified.
Steps:
- Check outlet: Test the wall socket with another appliance to confirm power is available.
- Inspect power cord: Look for cuts, burns, or kinks. Replace the cord if damaged.
- Check main fuse: Open the unit and locate the fuse on the main PCB or near the power entry. Test with a multimeter and replace with the same rating if blown.
- Examine PCB: Look for burnt components or tracks on the main board.
- Replace main PCB: If the fuse is good and there is still no response, the main control board is likely defective and should be replaced.
