How to Fix / Troubleshooting
Safety: Ensure the outlet is not live before touching any internal wiring. Unplug the unit.
Steps:
- Outlet check: Test the wall outlet with another appliance or a tester. Reset any tripped breaker or GFCI.
- Power cord: Inspect the cord for cuts, burns, or kinks. If damaged, replace the power cord assembly.
- Internal fuse: Remove the control panel or rear cover to access the main PCB. Locate the glass or ceramic fuse. Test it with a multimeter for continuity. Replace with the same rating if blown.
