Possible Causes

How to Fix / Troubleshooting
Safety first: Unplug the unit before inspection.
- Step 1 – Wiggle test: While the unit is running (use caution), gently wiggle the power cord at the back and the unit itself. If it shuts off, there is likely a loose connection. Then unplug before proceeding.
- Step 2 – Inspect cord strain relief: Ensure the cord is firmly held and not pulling on internal connections.
- Step 3 – Check internal connections: Open the housing and inspect the mains input connector, fuse holder, and PCB solder joints. Resolder any cracked joints if you are qualified.
- Step 4 – Check for overheating: Look for discoloration around power components. Ensure vents are clear and the unit has adequate airflow.
- Step 5 – Replace damaged parts: Replace any loose fuse holder, burnt connector, or the main control PCB if damage is extensive.
