How Many Amps Does a Microwave Use? Explained & Breaker Size Guide

How Many Amps Does A Microwave Use?

When it comes to kitchen appliances, the microwave is a staple in most households. It provides a convenient and quick way to heat up food, defrost frozen items, and even cook certain dishes. However, have you ever wondered how much power your microwave consumes? In this article, we will explore the topic of how many amps a microwave uses, providing valuable insights and troubleshooting tips for users.

Understanding Amps and Microwaves

Before diving into the specifics, let’s briefly explain what amps are and how they relate to microwaves. Amps, short for amperes, are a unit of electric current. They measure the flow of electricity through a circuit. In the case of microwaves, amps indicate the amount of current the appliance draws from the power source.

How Many Amps Does a Microwave Pull?

The amount of amps a microwave pulls depends on its power rating. Most household microwaves have power ratings ranging from 600 to 1,200 watts. To determine the amps, you can use the formula: Amps = Watts / Volts.

For example, let’s say you have a microwave with a power rating of 1,000 watts and it operates on a standard household voltage of 120 volts. Using the formula, we can calculate the amps as follows:

Amps = 1,000 watts / 120 volts = 8.33 amps

Therefore, this particular microwave would pull approximately 8.33 amps of current when in use.

What Size Breaker for Microwave?

When installing a microwave, it is crucial to ensure that the electrical circuit can handle the current it draws. This is where the size of the breaker comes into play. Breakers are designed to protect the circuit from overloading and prevent electrical hazards.

The size of the breaker needed for a microwave depends on its amp rating. Most microwaves fall within the range of 8 to 13 amps. To determine the appropriate breaker size, you should choose one that is slightly higher than the amp rating of your microwave.

For example, if your microwave pulls 8.33 amps, you would typically use a 10-amp breaker. This provides a safety margin and ensures that the breaker can handle the current without tripping.

Troubleshooting Examples and Solutions

While microwaves are generally reliable appliances, users may encounter certain issues that affect their performance. Here are some common troubleshooting examples and solutions:

  • Microwave not turning on: If your microwave fails to turn on, check if it is properly plugged into a functioning outlet. Ensure that the circuit breaker has not tripped. If the problem persists, it may indicate a faulty power cord or internal component. In such cases, it is advisable to call the authorized service for assistance.
  • Microwave not heating: If your microwave is running but not heating the food, make sure that you are using microwave-safe containers. Check if the door is closing properly and the seals are intact. If the issue persists, it could be due to a malfunctioning magnetron or other internal components. Contact the authorized service for further guidance.
  • Microwave tripping the breaker: If your microwave consistently trips the circuit breaker, it may indicate an overload. Ensure that the microwave is the only appliance connected to the circuit. If the problem persists, it could be due to a faulty microwave or an inadequate electrical circuit. Consider upgrading the circuit or consulting an electrician.

Replacement Parts for Microwaves

Like any other appliance, microwaves may require replacement parts over time. Common spare parts for microwaves include:

  • Microwave turntable motor
  • Microwave door switches
  • Microwave fuses
  • Microwave light bulbs
  • Microwave control panels

If you need to replace any of these parts, it is recommended to contact the authorized service or visit the official website of the microwave manufacturer. They can provide you with genuine replacement parts and ensure proper installation.

Service Centers in the United Kingdom

In the United Kingdom, microwaves are widely used, and users are generally satisfied with their performance. There are service centers located in various provinces across the country to provide assistance and repairs. If you encounter any issues with your microwave, it is advisable to call the authorized service center specified on the company’s official website. They can guide you to the nearest service center and provide the necessary support.


In conclusion, the number of amps a microwave uses depends on its power rating. Most microwaves pull between 8 to 13 amps. It is important to choose an appropriate breaker size to handle the current without tripping. If you experience any issues with your microwave, such as it not turning on or not heating, it is recommended to check the power source and contact the authorized service for assistance. Remember to use genuine replacement parts and consult the manufacturer’s official website for the most accurate and up-to-date information.
