Why Does My Breaker Trip When I Use the Microwave?

If a breaker trips when the microwave runs, the circuit may be experiencing a load or equipment problem. Don't keep resetting the breaker repeatedly without understanding why it trips.

Does anything else lose power?

Notice which other outlets, lights, or appliances shut off with the microwave. That can provide useful information about the circuit.

Did this just start?

A microwave that worked normally on the same circuit for years and suddenly causes trips may point to a different situation than a newly installed appliance.

Don't install a larger breaker

A breaker is matched to the circuit. Installing a higher-rated breaker to stop tripping can create a serious hazard when the wiring isn't designed for it.
