Microwave trips the household circuit breaker or blows a fuse when starting.

Safety warning: Repeatedly resetting a tripping breaker can be dangerous. Unplug the microwave and do not continue to use it until the cause is identified.

• Check circuit load: Ensure the Ambiano microwave is on a dedicated circuit or not sharing with other high-wattage devices.
• Test another outlet: Plug the microwave into a different properly rated outlet to rule out wiring issues.
• Internal inspection (technician-level):
  • Remove the outer cover and inspect for obvious shorts, burnt components, or melted wires.
  • Discharge the HV capacitor safely.
  • Test the capacitor, diode, and magnetron for shorts with a multimeter.
• Replace faulty components: Replace any shorted HV parts with Ambiano-compatible replacements, or consider replacing the entire microwave if multiple components are involved.
