What Should You Do When Your GE Microwave Oven Breaks? Step-by-Step Repair Guide

Dealing with a broken microwave can be frustrating, but with the right steps, you can often fix a GE microwave yourself. Here’s an easy-to-follow guide that covers the basics of microwave oven repair, focusing on GE models, including the popular GE over-the-range microwave.

Safety First

Before you do anything else, ensure your safety:

  • Unplug the microwave: Always unplug the appliance to avoid any risk of electric shock.
  • Check for any blown fuses or tripped circuits: Make sure the power to the microwave is off, not just at the microwave but also at the circuit breaker.

Troubleshooting the Issue

  • Identify the problem: Is the microwave not heating? Does the turntable not spin? Or maybe the microwave just won’t start. Understanding the symptom can point you towards the issue.
  • Consult the instruction manual: Look for the troubleshooting section in your microwave’s manual. GE appliances, including their microwaves, come with helpful step-by-step instructions.

Check the Fuse

  • Access the fuse: Using a Phillips screwdriver, open the microwave’s panel to locate the fuse. Microwaves typically have a ceramic fuse hidden behind the panel.
  • Test for continuity: Using a multimeter, check if the fuse is blown. No continuity means the fuse needs replacing.

Inspect the Door Switch

  • Locate the door switches: These are usually found near the door latch.
  • Check function and continuity: Use the multimeter to test each switch. If any switch lacks continuity when activated, it needs to be replaced.

Examine Other Components

  • Inspect the power cord: Sometimes the issue is as simple as a damaged power cord or plug. Look for any obvious signs of wear or damage.
  • Look at the control panel and sensor: Electronic issues often arise here, especially if buttons are unresponsive or the sensor isn’t detecting correctly.

Advanced Troubleshooting

  • Test the magnetron and capacitor: These are more complex issues. If you’re comfortable and knowledgeable, you can test these components for functionality. If not, it might be time to call in a professional.
  • Voltage checks: Be extremely careful if checking anything related to voltage. If unsure, this is definitely a step where professional help is recommended.


After walking through the steps to troubleshoot and potentially repair your GE microwave, you might find that the problem is resolved, and you can return to cooking and experimenting with new recipes in no time. Whether it’s a simple fuse replacement, a door switch fix, or more complex issues like a faulty high voltage capacitor or transformer, knowing how to identify and tackle these issues can save you time and money. However, if the fault persists despite your efforts, it may be time to consult a professional technician. Some problems, particularly those related to the microwave’s power supply, motor, or electrical systems, require specialized tools like a voltage tester and an understanding of electrical safety procedures that go beyond typical DIY maintenance.

Remember, regular maintenance of your appliance can prevent many common problems. Keeping the cavity clean, ensuring the door lock is functional, and occasionally checking components like the thermostat and tube can extend the life of your microwave. But if you find yourself in over your head, especially when dealing with components like the transformer or capacitor that can retain high voltage, prioritize safety and consider getting help from a professional.

As you continue to use and maintain your microwave, consider exploring all the culinary possibilities it offers—from quick recipes that let you boil or steam food in minutes to kitchen hacks that make your cooking experience more efficient. Even if a problem arises, now you have the knowledge to either pass the baton to a technician or capably handle many issues on your own. Keep this guide handy in your garage or wherever you store your tools, as you never know when it might come in handy to tackle the next microwave challenge!
