Possible Causes

Blown internal fuse,Faulty power cord,Failed mains interference filter,Open thermal fuse in primary circuit

How to Fix / Troubleshooting

Safety first: Unplug the microwave before any inspection. Internal fuses are not user-serviceable in some regions; check local regulations.

  • 1. Check outlet: Test the wall socket with another appliance to confirm power is available.
  • 2. Inspect plug and cord: Look for visible damage, burns, or cuts. If damaged, the cord must be replaced.
  • 3. Internal fuse check (for trained persons): Remove the outer cover and locate the mains fuse near the power entry. Test with a multimeter. If blown, investigate the cause (shorted components) before replacing with the exact same rating.
  • 4. Thermal fuse: Some Beko models include a thermal fuse in series with the primary circuit. Test for continuity and replace if open, ensuring correct temperature rating.

Warning: Simply replacing a blown fuse without finding the root cause can lead to repeated failures or fire risk.
