Reasons Why Your Microwave Is Tripping Your Breaker


If your microwave keeps tripping your breaker, you're not alone. This is a common problem that many homeowners face, and it can be frustrating and even dangerous if left unaddressed. In this blog post, we'll explore some of the common reasons why your microwave keeps tripping your breaker and provide practical solutions to help you fix the problem.

1. Overloaded Circuit

One of the most common reasons why your microwave keeps tripping your breaker is an overloaded circuit. This happens when you have too many appliances or devices plugged into the same circuit, causing it to exceed its capacity. To fix this issue, you can try unplugging some appliances or relocating them to different circuits. You can also consider upgrading your electrical system to handle more power.

2. Faulty Microwave

Another reason why your microwave may be tripping your breaker is that it's faulty. If the microwave has a short circuit or other electrical problems, it can cause the circuit breaker to trip. In this case, the best solution is to replace the microwave with a new one.

3. Loose Electrical Connections

Loose electrical connections can also cause your microwave to trip the breaker. This happens when the wires or connections become loose or damaged, causing a short circuit. To fix this issue, you'll need to hire a professional electrician to inspect and repair your electrical system.

4. Overheating Microwave

If your microwave is overheating, it can also cause the circuit breaker to trip. This can happen if the microwave is too old or if it's been used for an extended period without proper ventilation. To prevent this issue, make sure your microwave is properly ventilated and consider replacing it if it's too old.

5. Faulty Circuit Breaker

Lastly, a faulty circuit breaker can also be the reason why your microwave keeps tripping the breaker. If the breaker is damaged or worn out, it may not be able to handle the electrical load from your microwave. In this case, you'll need to replace the circuit breaker with a new one.


In summary, there are several reasons why your microwave may be tripping your breaker, including an overloaded circuit, a faulty microwave, loose electrical connections, an overheating microwave, and a faulty circuit breaker. By identifying the root cause of the problem, you can take the necessary steps to fix it and prevent it from happening again in the future.
