Possible Causes

Blown internal line fuse, Failed low-voltage transformer or SMPS on control PCB, Shorted control PCB components, Loose mains wiring connection

How to Fix / Troubleshooting

Safety first: Unplug the microwave before any inspection.

Basic checks:

  • Verify wall outlet: Test the outlet with another appliance to ensure it supplies power.
  • Check power cord: Inspect the Clatronic power cord for cuts, burns, or kinks. Do not use the unit if the cord is damaged.

Internal checks (technician):

  • Remove the cabinet (unplugged). Check the internal line fuse on the filter board or control board. Replace only with the exact same rating and investigate why it blew.
  • Inspect the mains filter board and wiring for burn marks or loose connectors.
  • Measure low-voltage outputs from the control PCB power supply (e.g., 5V, 12V) if equipped and safe to do so.

Warning: If the fuse blows again immediately, there is likely a shorted component. Do not bypass fuses. Contact a professional.
