How to Fix / Troubleshooting
Safety: Unplug the unit before opening any covers. Use a properly rated multimeter if testing live circuits.
Steps:
- Check outlet: Test the wall outlet with another appliance to confirm power is present.
- Inspect power cord: Look for cuts, burns, or kinks. If damaged, replace the Argo power cord set.
- Access main PCB: Remove the rear or side panel to expose the main control board. Locate the onboard fuse.
- Test fuse: Use a multimeter to check continuity of the fuse. If open, replace with the same type and rating. If it blows again immediately, there is a deeper fault.
- Check for burn marks: Inspect the PCB for burnt components or tracks. If present, replace the Argo main control PCB.
- Reassemble and test: After replacing faulty parts, reassemble and plug in. If the unit still does not power on, seek professional diagnosis.
