Possible Causes
Blown internal line fuse, Faulty power cord, Tripped household circuit breaker, Shorted high-voltage component causing fuse to blow
How to Fix / Troubleshooting
Safety first: Unplug the microwave before any inspection. Internal fuses are not user-serviceable in many regions.
- Step 1 – Check outlet and breaker: Test the wall outlet with another appliance. Reset the circuit breaker or replace the house fuse if tripped.
- Step 2 – Inspect power cord: Look for visible damage. If damaged, do not use the appliance.
- Step 3 – Internal fuse (technician): A professional can open the cabinet, test the line fuse, and determine why it blew (often due to a shorted HV diode, capacitor, or door switch).
- Step 4 – Replace faulty parts: Replace the fuse only after the underlying fault is corrected, using the exact type and rating specified by Bauknecht.
