Possible Causes

Blown internal line fuse, Failed low-voltage transformer or SMPS on control board, Shorted wiring harness, Faulty door filter board (noise filter)

How to Fix / Troubleshooting

Safety first: Unplug the microwave. Internal fuses and power components are connected directly to mains voltage.

User-level checks:

  • Verify that the wall outlet is supplying power by testing with another appliance.
  • Check that the plug and cord are not damaged.

Technician-level checks:

  • Remove the outer cover and locate the main line fuse near the power entry or noise filter board.
  • Test the fuse with a multimeter; if open, investigate for shorts before replacing.
  • Inspect the noise filter board and wiring for burn marks or melted insulation.
  • Check the low-voltage supply section on the control PCB (transformer or SMPS) for output voltages as per Hoover service data.

Note: Never bypass a blown fuse without finding the root cause. If you are not trained in mains-voltage electronics, contact a professional.
