Why does my circuit breaker trip or fuse blow when I turn on the microwave?

First question, is the microwave a small sit-on counter type? Have you tried another outlet to make sure the microwave is working correctly? Your microwave may be tripping the power due to an issue with its electricity supply.

Microwaves are a common culprit for overloaded electrical circuits, which can be both frustrating and concerning for homeowners. You more than likely have too many items on that same circuit that the microwave is plugged into. If you try to run multiple appliances on the circuit at the same time, it can exceed the circuit’s rating and trip the breaker. Appliances include refrigerator, coffee pot, toaster or any other appliance that may be plugged into any other receptacle or plug-in, in the kitchen.

MN Electrical Code requires that a house has at least two 20-amp receptacle circuits in the kitchen for small appliances. For example, if you have 6 receptacles in your kitchen, more than likely there are 3 on one circuit and 3 on the other. Most newer homes (1980's-current) do not have a problem with a microwave tripping circuit breakers, unless it is a high wattage unit. If you having and have a newer home and/or newer wiring and circuits in your kitchen, have an electrician check all the connections at the receptacles and in the breaker panel for any loose connection which will cause heat and trip the circuit breaker.
