how to fix microwave tripping circuit breaker


Microwave ovens have become an essential kitchen appliance for most households. They offer convenience and efficiency, making our lives easier. However, one common issue that microwave owners frequently encounter is a tripping circuit breaker. This can be frustrating and inconvenient, especially when you rely heavily on your microwave for cooking or reheating meals. In this article, we will explore various methods to fix a microwave that keeps tripping the circuit breaker, allowing you to enjoy uninterrupted use of your appliance.

Understanding the Circuit Breaker

Before delving into solutions, it is crucial to understand what a circuit breaker is and why it trips. A circuit breaker is a safety device designed to protect electrical circuits from damage caused by excess current. When the circuit is overloaded or a short circuit occurs, the breaker automatically shuts down, cutting off the power supply. This prevents potential hazards like overheating or electrical fires.

Microwaves typically operate on a 15-amp circuit, meaning they require a significant amount of power to function properly. However, if multiple appliances are connected to the same circuit, it can exceed the circuit's capacity, leading to the tripping of the breaker. Therefore, it is essential to identify the root cause of the problem to implement the appropriate solution.

Inspecting the Microwave

The first step in resolving the issue is to inspect your microwave. Look out for any visible signs of damage, such as frayed wires or burnt components. Additionally, check if any foreign objects are trapped inside the microwave, as they can cause electrical issues. Gently shake the appliance to check if anything rattles or moves, indicating loose components.

If you notice any visible damage or loose parts, it is highly recommended to contact a professional technician to repair the microwave. Attempting to fix the issue yourself might exacerbate the problem or pose a safety risk.

Verifying the Power Outlet

Sometimes, the underlying issue might not lie with the microwave itself but with the power outlet. Faulty or damaged outlets can lead to electrical problems, including circuit breaker tripping. Follow these steps to verify the condition of your power outlet:

1. Switch it Off - Before examining the outlet, ensure that the power is switched off from the circuit breaker to prevent any electrical mishaps.

2. Inspect the Outlet - Carefully examine the power outlet for any visible signs of damage, such as burn marks, discoloration, or loose connections. If you notice any issues, it is crucial to replace the outlet immediately. Consult with a professional electrician if you are uncertain about the replacement process.

3. Test the Outlet - Use a multimeter or a circuit tester to verify if the outlet is functioning correctly. If you are unfamiliar with these tools or unsure about the process, it is best to seek help from a professional electrician.

Reducing Power Consumption

If you have ensured that both the microwave and power outlet are in proper working condition, the issue may be a result of excessive power consumption. In such cases, reducing the power consumption of your microwave can help prevent the circuit breaker from tripping. Consider the following steps:

1. Disconnect Other Appliances - If your microwave is on the same circuit as other high-power appliances, disconnecting them while using the microwave can alleviate the issue. Sharing power within a single circuit lowers the available current for each appliance, increasing the chances of overloading the circuit.

2. Adjust Power Levels - Most microwaves offer multiple power levels to cater to various cooking requirements. By decreasing the power level, the microwave consumes less electricity, reducing the strain on the circuit. However, it is important to note that lower power levels might increase cooking times.

3. Avoid Concurrent Usage - If multiple individuals in your household frequently use the microwave at the same time, it can contribute to excessive power consumption. Temporarily staggering the usage can prevent the circuit from being overloaded.

4. Unplug Unused Appliances - Even when appliances are not in use, they continue to draw a small amount of power. Unplugging any unnecessary appliances from the same circuit can help in minimizing power consumption and protecting against circuit overload.

Consider an Alternate Circuit

In some cases, the circuit to which your microwave is connected may be overloaded or unable to handle the appliance's power requirements. To resolve this issue, you can consider connecting your microwave to an alternate circuit. Follow these guidelines:

1. Identify the Dedicated Circuit - Check if your microwave is connected to a dedicated circuit, solely intended for high-power appliances. Dedicated circuits ensure optimal performance and prevent circuit breakers from tripping. If your microwave is not connected to a dedicated circuit, consider moving it to one. Consult with a professional electrician for assistance during this process.

2. Relocate the Microwave - If switching to a dedicated circuit is not feasible, you might need to relocate your microwave to a different area in your kitchen. Ensure that the new location has a circuit that can handle the microwave's power requirements without overloading it.


In conclusion, a microwave tripping a circuit breaker can be an inconvenience, but with the appropriate troubleshooting steps, you can rectify the issue. Start by inspecting the microwave for any visible damage or loose components. Then, verify the power outlet to ensure it is in proper working condition. If the problems persist, attempt to reduce the power consumption of your microwave by disconnecting other appliances, adjusting power levels, avoiding concurrent usage, or unplugging unused appliances.

If these measures do not solve the problem, consider connecting your microwave to an alternate circuit, such as a dedicated circuit or relocating it to an area with an appropriate power supply. Remember, if you are uncertain about any electrical repairs or installations, it is always best to consult with a professional technician or electrician to ensure your safety and the efficient functioning of your microwave.
