How to Fix / Troubleshooting
Safety first: Unplug and allow the unit to cool before inspection.
Steps to diagnose shutdowns:
- Check ventilation: Ensure vents are clear and the unit has adequate space around it.
- Inspect mains connections: Open the housing and tighten any screw terminals or spade connectors on the mains input and power board.
- Examine PCB: Look for heat discoloration around voltage regulators or transformers on the main control PCB.
- Test under load: After reassembly, run the unit and gently tap the housing near the power board. If it shuts off, a loose connection or cracked solder joint is likely.
- Repair or replace: Resolder cracked joints if skilled, or replace the main control PCB.
Warning: Do not continue using the unit if it frequently shuts off; this can indicate overheating or electrical faults.
