Why Does My Microwave Keep Tripping The Breaker

Is your microwave constantly causing your circuit breaker to trip, leaving you puzzled and inconvenienced? You’re not alone in facing this common household issue. In this article, we’ll dissect the problem, shedding light on why your microwave might be triggering those frustrating breaker interruptions. We’ll delve into the fundamentals of your electrical system, examine potential culprits, and offer practical solutions to put an end to the annoyance. Say goodbye to the hassle and confusion as we unravel the mystery of “Why Does My Microwave Keep Tripping the Breaker?” – your guide to a smoother microwave experience starts here.

Why Does My Microwave Keep Tripping The Breaker?

Your microwave may be tripping the breaker due to reasons such as overloading the circuit, a faulty microwave, aging wiring or outlets, sharing the circuit with other high-power appliances, or running the microwave on its highest power setting for extended periods.

Possible Causes Of Your Microwave Tripping The Breaker

Now that we have a basic understanding of how circuit breakers work let’s explore some common reasons why your microwave might be causing the breaker to trip:

  1. Overloading The Circuit: One of the most common reasons for a breaker to trip is overloading the circuit. Microwaves draw a significant amount of power when they are running, and if the circuit is already handling a heavy load from other appliances or devices, it can trip to prevent overheating and potential fires.
  2. Faulty Microwave: A malfunctioning microwave can also be the culprit. If there’s an internal electrical issue within the microwave itself, it can cause a short circuit, leading to the breaker tripping.
  3. Aging Wiring Or Outlets: Over time, the wiring and outlets in your home can deteriorate. If they are old or damaged, they may not be able to handle the power demand of your microwave, leading to a breaker trip.
  4. Microwave And Other Appliances On The Same Circuit: In some cases, the microwave may share a circuit with other high-power appliances like a refrigerator or air conditioner. When these appliances run simultaneously, it can overload the circuit and trip the breaker.
  5. Microwave Power Setting: Running your microwave on its highest power setting continuously can draw a lot of power, which might exceed the circuit’s capacity. Lowering the power setting or using the microwave in shorter bursts can help.

By identifying the specific cause of your situation, you can take targeted steps to resolve the issue and enjoy uninterrupted microwave usage.

Troubleshooting And Solutions

When your microwave keeps tripping the breaker, it’s essential to troubleshoot the problem and implement effective solutions. Here’s a step-by-step guide to help you address this issue:

Check Other Appliances: 

Start by identifying which other appliances or devices are on the same circuit as your microwave. Avoid running them simultaneously with the microwave, especially if they are high-power appliances. If multiple such devices share the circuit, consider redistributing them to different circuits.

Inspect Your Microwave: 

Examine your microwave for visible damage, loose wires, or burnt components. If you detect any issues, it’s advisable to consult a professional technician for repairs or consider replacing the microwave, especially if it’s old and beyond repair.

Upgrade Your Wiring: 

If your home has older wiring that is not up to code, it may be time for an upgrade. Consult an electrician to assess your electrical system and make necessary improvements. Upgrading your wiring enhances the circuit’s capacity and reduces the likelihood of breaker trips.

Consider A Dedicated Circuit: 

If you frequently experience breaker trips with your microwave, think about having a dedicated circuit installed exclusively for the microwave. This ensures that the microwave has its own circuit, reducing the chances of overloading.

Adjust Microwave Power Settings: 

If you tend to run your microwave on its highest power setting continuously, try lowering the power or using shorter cooking times. This reduces the power demand and decreases the likelihood of tripping the breaker.

Consult A Professional: 

If the issue persists or if you’re uncomfortable working with electrical systems, it’s best to seek the expertise of a licensed electrician. They can diagnose and resolve the problem safely and efficiently.

By following these troubleshooting steps and implementing the appropriate solutions, you can enjoy the convenience of your microwave without the hassle of constant breaker interruptions. Prioritizing safety and seeking professional help when needed ensures a smooth and reliable electrical system in your home.

When To Seek Professional Help

While some troubleshooting steps can be performed by homeowners, there are instances when it’s crucial to seek professional help to address the issue of your microwave tripping the breaker:

  • Persistent Breaker Trips: If your microwave continues to trip the breaker despite your best efforts to resolve the problem, it’s a clear sign that there may be a more complex underlying issue. Professional electricians have the expertise to identify and rectify such problems efficiently.
  • Safety Concerns: Dealing with electrical systems can be hazardous, especially if you’re not experienced. If you have safety concerns or doubts about working with electricity, it’s always safer to leave the troubleshooting and repairs to qualified electricians who have the necessary training and equipment to handle electrical issues safely.
  • Complex Electrical Systems: In homes with intricate or outdated electrical systems, pinpointing the exact cause of breaker trips can be challenging. Electricians have the knowledge and tools to navigate complex setups and diagnose issues accurately.
  • Wiring Upgrades: If the solution to your problem involves upgrading your home’s wiring or making significant electrical modifications, it’s a job best left to professionals. They can ensure that the work complies with local electrical codes and regulations, guaranteeing the safety and reliability of your electrical system.
  • Peace Of Mind: Seeking professional assistance not only resolves the immediate issue but also provides peace of mind. You can be confident that the problem has been addressed correctly, reducing the risk of future electrical problems or safety hazards.

If your microwave consistently trips the breaker and you’re unable to identify or resolve the issue on your own, it’s wise to enlist the services of a licensed electrician. They have the skills and knowledge to diagnose and fix electrical problems safely, ensuring the smooth operation of your microwave and the overall safety of your home’s electrical system.


Dealing with a microwave that keeps tripping the breaker can be frustrating, but it’s a problem that can be addressed with some troubleshooting and, if necessary, professional assistance. Understanding the reasons behind the breaker trips and taking proactive steps to mitigate them can help you enjoy the convenience of your microwave without the inconvenience of constant interruptions. Remember to prioritize safety when dealing with electrical issues and always consult a qualified electrician if you’re unsure about any aspect of your home’s electrical system. With the right approach, you can ensure that your microwave runs smoothly and safely.
