How to Fix / Troubleshooting
Safety first: Ensure the unit is unplugged before any inspection. Do not bypass safety fuses.
Steps to troubleshoot no power:
- Check outlet and cord: Test the wall outlet with another appliance. Inspect the Princess power cord for cuts, burns, or loose plug blades.
- Inspect internal fuse: Remove the outer housing to locate the internal glass or thermal fuse on the main control PCB or mains filter board. Test for continuity with a multimeter. If blown, investigate for shorts before replacing.
- Examine PCB: Look for burnt components, cracked solder joints, or swollen capacitors in the power supply section of the main control PCB.
- Replace components: Replace a blown internal fuse only with the same rating. If the fuse blows again or the board shows damage, replace the main control PCB or mains filter board as a complete assembly.
