Bosch microwave not working — is it urgent, who do I call?
Usually a blown line fuse, a failed door-interlock switch, or a faulty magnetron. The first check: the plug, the breaker and the door, once. A breaker that trips again goes to an electrician. Anything burnt, melted or scorched on the microwave or at its plug moves this up: a photo that shows wiring a person could touch makes the Triage Profile say EMERGENCY, and the word holds.

Symptoms & causes
Usually a blown line fuse, a failed door-interlock switch, or a faulty magnetron.
When a Bosch microwave is not working at all, it typically means there is no power, no display, and no response from any buttons. This complete lack of function often points to a fundamental power supply issue, such as a tripped circuit breaker, a blown internal fuse, or a faulty door interlock switch. Less commonly, a complete failure could stem from a defective main control board or a serious wiring fault within the appliance.

Why is my Bosch microwave completely dead?
Most commonly, a tripped circuit breaker or a blown internal fuse is the culprit preventing any power to the unit.
