How to Fix Microwave Tripping Circuit Breaker?

Before letting you know how to fix microwave tripping circuit breaker, let’s know about the history of microwaves. The microwave oven was invented in 1945 by Percy Spencer. He was an American engineer. He would work on radar technology at Raytheon. Spencer noticed that a chocolate bar in his pocket had melted when he was working with a magnetron. He experimented further and found that microwaves could be used to cook food quickly. The first commercial microwave oven was introduced in 1945. It was a large, heavy (weight 750 pounds), and expensive appliance that was mainly used in restaurants.

What is Microwave Oven?

A microwave oven is a kitchen appliance that uses microwave radiation to cook food. Microwaves are a type of non-ionizing radiation. It means that they do not have enough energy to break chemical bonds or cause DNA damage. Microwaves work by causing water molecules in food to vibrate. This vibration creates heat and cooks food. Microwaves are very efficient at heating food, and they can cook food much faster than conventional ovens.

How to Fix Microwave Tripping Circuit Breaker?

The circuit breaker is used for protection purposes from undesired electric current. Most electrical or electronic devices use circuit breakers or fuses to make sure that the device is safe. However, we have given here a few steps on how to fix microwave tripping circuit breaker.

Check The Circuit Breaker

Do you know how often circuit breakers go bad? Circuit breakers can go bad for a variety of reasons. That’s why the first thing you should check the circuit breaker that its mechanism working properly or not. If you get any issues, then reset the breaker and ensure that the microwave is working. If the breaker trips again, then there is a problem with the microwave. So, take a step or get help from your nearby technician if you don’t have the skill in it.

Check The Microwave Power Cord

Make sure that the power cord is not damaged and that it is plugged in securely. You can also try plugging the microwave into a different outlet to see if that solves the problem. This is a simple inspection, if you see the faulty power cord then change it and connect another one to supply electricity.

Inspect the Microwave’s Door Switches

The door switches on a microwave are responsible for ensuring that the door is closed properly. If the door switches are not working properly, then the microwave will never be able to draw enough power and the circuit breaker may trip. So, if this happens then go to the technician and change the door switch.

Check The Microwave’s Capacitor

The capacitor is an essential device for an electronic device. It stores the charge. The capacitor in a microwave stores electricity and helps to power the microwave’s magnetron. If the capacitor is faulty, it can cause the microwave to draw too much power and trip the circuit breaker. So, it is an important term to make sure that the capacitor is well set.

Call an Electrician

Suppose, you have checked all of the above and found no issue but the microwave is still tripping the circuit breaker. In this case, call an electrician and let him inspect your microwave to figure out the problem. Hopefully, an electrician will be able to diagnose the problem and fix it.

On the other hand, there are some additional key points that can be responsible to trip the circuit breaker. You should keep the focus on that, such as

  • Make sure that the microwave is not overloaded.
  • Do not plug too many appliances into the same circuit as the microwave.
  • User surge protector because it will help to protect the microwave from power surges.
  • Older microwaves are more likely to have problems with the door switches or the capacitor.

How Do I Stop My Microwave from Tripping the Circuit Breaker?

  • The first thing you should check is the circuit breaker and keep focus on the circuit breaker installation that your microwave is plugged into. Make sure that it is not tripped.
  • If your microwave is the only appliance plugged into the circuit. In that case, the problem is likely with the microwave itself. However, if there are other appliances plugged into the same circuit. Then try to unplug them one by one.
  • Make sure that the microwave’s power cord is not damaged. The cord may be causing a short circuit. And it could be tripping the breaker.
  • If you see that the cord is not damaged, then the problem may be with the microwave itself. For this reason, inspect the microwave for any signs of damage, such as loose wires, damage to any component, burnt smell, etc. If you see any damage, then do not use the microwave and call an electrician to repair it.

How to Prevent Microwave from Tripping the Circuit Breaker?

There are some essential ways to prevent microwaves from tripping the circuit breaker. So, take a look the steps and apply them if you face such an undesired event.

  • If possible then plug your microwave into a dedicated circuit. It means that the circuit will only be used for the microwave. So, there will be no other appliances on the same circuit.
  • Do not plug in too many other appliances on the same circuit.
  • You should use a surge protector. Because a surge protector can help to protect your microwave from power surges, which can also cause the breaker to trip.

What to Do If an Appliance Keeps Tripping the Breaker?


If an appliance keeps tripping the breaker what to do? There are a few things you can do to troubleshoot the problem. So, take a look at a glance.

Why Your Microwave Tripp Your Circuit Breaker?

Why is my microwave tripping the breaker all of a sudden? If you have checked all of these things how much do you know but your microwave is still tripping the breaker? The best is to call a qualified electrician or technician to diagnose the problem. However, there are two main reasons why your microwave might be tripping your circuit breaker.

  • Overloaded circuit. 
  • Faulty microwave. 

Does Microwave Trip the Breaker When Push Start?

Yes, a microwave can trip the breaker when you push the start. Because the microwave draws a lot of power when it first starts up. It can overload the circuit. If the circuit is overloaded, the breaker will trip to prevent damage to the wiring. So, let’s see some things that you can do to prevent your microwave from tripping the breaker when you push start:

  • Make sure that the microwave is plugged into a dedicated circuit. 
  • Avoid overloading the circuit. 
  • Use a surge protector. 
  • Faulty microwave.

  • Loose or incorrect wiring.

Does Circuit Breaker in Microwave Go Bad?

Yes, a circuit breaker in a microwave can go bad. But why circuit breaker goes bad? Basically, there are some common reasons for it. However, we have brought here some crucial factors for circuit breakers go bad in the microwave.

  • Overloading the circuit.
  • Faulty microwave.
  • It damaged the power cord.

If you suspect that the circuit breaker in your microwave is terrible. At this stage, you should check it. If you found any issue, then repair it and prepare it to use continue.

Is AC Voltage More Dangerous Than DC Voltage?

Yes, in some cases AC voltage is considered more dangerous than DC voltage. There are a few reasons for this. Let’s see why AC voltage is more dangerous than DC voltage.

  • AC has a frequency. The frequency of AC current can cause involuntary muscle contractions. The frequency of AC current is 50 or 60 Hz. It is the same frequency as the human heart. When AC current flows through the body, it can cause the heart to beat. It can lead to cardiac arrest. But the DC current does not have this effect due to the absence of frequency.
  • AC current can induce a voltage across the body even if there is no complete circuit. It is because the human body has capacitance. It means that it can store an electric charge. When AC current flows through the body, it can create a voltage across the body’s capacitance, if it does not complete the circuit.
  • AC current is more easily stepped up to high voltages. This is because AC voltage can be stepped up using transformers, which are relatively simple devices. DC voltage, on the other hand, can only be stepped up using more complex electronics.

It is noted that both AC and DC voltage can be dangerous, and the level of danger depends on a number of factors, including the voltage, the current, and the duration of the shock. However, in general, AC voltage is considered to be more dangerous than DC voltage of the same level.

How to Avoid Electric Shock?

Let’s follow some techniques to get rid of the electric shock.

  • Always be aware of the presence of electrical current.
  • Do not touch electrical wires or appliances that are not properly insulated.
  • Use a ground fault circuit interrupter (GFCI) to protect yourself from electric shock.
  • Be careful when working with high-voltage equipment.
  • If you do receive an electric shock, seek medical attention immediately.

Does Microwave Trips Breaker After 2 Minutes?

Yes, a microwave can trip the breaker after 2 minutes. If your microwave keeps tripping the breaker after 2 minutes, you should be unplugging any other appliances that are plugged into the same circuit. It is noted that, if the breaker trip at any time then you must disconnect your microwave from the power supply.

Does Microwave Keep Tripping Breaker After 30 Seconds?

Yes, a microwave can keep tripping the breaker after 30 seconds if it is drawing too much power. Microwaves draw around 1200 watts of power. It is a lot of power for a single appliance. If there are too many other appliances plugged into the same circuit, then it can easily create an overload and trip the breaker. We have given here some possible reasons why your microwave might be tripping the breaker after 30 seconds.
