Possible Causes

How to Fix / Troubleshooting
Safety first: Ensure the unit is unplugged before opening. Do not bypass fuses.
- Check outlet and breaker: Test the wall outlet with another appliance. Reset any tripped breaker.
- Inspect power cord: Look for cuts, kinks, or burn marks. Gently wiggle the cord at the entry point while plugged in (with caution) to see if power flickers; if so, replace the cord.
- Open and inspect fuse: With the unit unplugged, remove the housing and locate the internal fuse on or near the main control PCB. Test for continuity. If blown, investigate for shorts before replacing with the same rating.
- Check mains connector: Ensure the cord’s internal connector and any line filter are firmly attached to the PCB.
- Replace PCB if needed: If the fuse is good and power still does not reach the low-voltage section, the main control PCB is likely defective and should be replaced.
