Why does my microwave trip the circuit breaker?

The answer: The microwave is overloading the electrical circuit. In other words, the circuit is rated to handle a certain amount of amps (unit of electrical current), and the microwave is exceeding that amount, causing the breaker to trip. The microwave is malfunctioning and pulling too much electrical current.

.

Similarly, you may ask, how do you fix a microwave that keeps tripping?

Determining if your microwave is faulty is actually relatively simple. Move the microwave to another area and plug it into an outlet that is connected to a higher amp breaker. Turn the microwave on and see what happens. If nothing happens (the microwave works fine), then the problem is a shared circuit.

Beside above, should a microwave be on its own breaker? The microwave oven needs a dedicated 20-amp, the 120/125-volt circuit to feed it. This will require 12/2 NM wire with a ground. Although it's not uncommon to see microwave ovens plugged into standard appliance outlets, larger microwave ovens can draw as much as 1500 watts, and these need their own dedicated circuits.

Subsequently, one may also ask, why is my microwave tripping?

There are two possible causes of why the microwave keeps tripping the circuit breaker: The microwave is not functioning properly and is pulling too much electrical current. Too many electrical appliances are plugged into the same circuit.

How do you fix a circuit breaker that keeps tripping?
