How to Fix / Troubleshooting
Safety first: Ensure the outlet is not live before inspecting the cord. Unplug the unit before opening any panels.
Steps to diagnose:
- Check outlet and breaker: Test the outlet with another device and reset any tripped breakers or GFCI outlets.
- Inspect power cord: Look for cuts, burns, or kinks. Replace the cord if damaged.
- Check internal fuse: Remove the rear panel and inspect the main control board for a small fuse. If blown, replace with the same rating. If it blows again immediately, there is a short that needs professional diagnosis.
- Replace control board: If the fuse is good but no power is distributed, the main PCB's power supply may have failed and should be replaced.
When to call a professional: If you are not comfortable working with electrical components, contact a technician.
