Symptom
Microwave makes loud buzzing, humming, or crackling noises during operation.
Abnormal Noise – High Voltage or Mechanical Interference
Symptom
Microwave produces uneven heating; some areas of food are cold while others are very hot.
Uneven Heating / Distribution Issue
Symptom
Microwave runs (light, fan, and turntable operate) but food does not heat up.
No Heating – High Voltage or Magnetron Failure
Symptom
Microwave runs but stops before the set time is reached, without any error code.
Intermittent Shutdown – Thermal or Door Switch Issue
Symptom
Microwave trips the household circuit breaker or blows a fuse when starting.
Short Circuit or Overcurrent on Start
Symptom
Microwave turntable does not rotate, but heating still occurs.
Turntable Drive Failure
Symptom
On combi Hansa microwaves, convection (hot air) mode does not heat or fan does not run.
Convection Heater or Fan Failure
Symptom
On combi Hansa microwaves, grill function does not heat but microwave function works.
