DIY Built-In Microwave Repair for Common Issues on Major Brands

At [Your Company], we know how frustrating it can be when your built-in microwave stops working correctly, particularly when repair services may be expensive and difficult to access. That’s why we’re here to provide you with all the information you need to repair common issues occurring in built-in microwaves from some of the most popular brands. Utilizing our DIY guide, you’ll be able to save time, money and effort by learning how to perform some simple repairs to your own built-in microwave.

Fuse is Blown

One of the most common and straightforward issues you can face with a built-in microwave is a blown fuse. This issue may be the result of a power surge, a short circuit, or even a small issue with the appliance itself. To diagnose a blown fuse, we recommend first unplugging the appliance and removing the outer casing to expose the wiring and internal elements. Look for a fuse on the main wiring board that has snapped in half or melted.

If you’ve identified a blown fuse, you’ll need to replace it with a brand new one that’s been manufactured for use in microwaves. The new fuse should have the same size, rating, and type as the original. However, it’s important to take extra ease when replacing the fuse and make sure all the connection terminals have been securely connected.

Magnetron Fails to Work

The magnetron is the component responsible for producing the microwave radiation to heat your food. Should the magnetron become faulty it can lead to cold spots, a lack of power, or nothing to happen at all. To diagnose, you’ll need to open your appliance up, disconnect the power source and then use a multi-meter to measure the resistance across the magnetron’s terminals.

If you find that the resistance is too low, then it’s likely that the magnetron has become defective. To repair this issue, it’s recommended you call your service provider, as magnetron replacement must be handled by trained technicians.

Turntable Issues

Another common issue with built-in microwaves you may experience is a faulty turntable. This is the component that rotates your food around the oven to ensure it cooks evenly. To troubleshoot, you’ll need to disconnect your appliance from mains electricity and then check the turntable motor and drive coupler.

You can use a multimeter to measure the resistance across the motor’s terminals and see if it’s functioning correctly. If the resistance appears far too high, then you’ll need to replace your appliance’s turntable motor.

Door switch

Lastly, let’s take a look at the door switch. This component ensures your microwave will only run when the door is securely shut. To diagnose, you’ll need to use a multimeter to measure the door switches resistance. If the resistance appears too low then it’s likely that this component has become faulty.

Fortunately, replacing a door switch is relatively straightforward. You’ll need to access the interior of your appliance and then unplug the old switch. You can then remove the outer casing, take out the old switch and plug in the new one. Remember to double-check the connections are secured.


As we’ve seen, there are a handful of common issues you can face when using built-in microwaves from popular brands. You’ll know you have a blown fuse if you find it snapped or melted on the main wiring board, or should your cooker randomly turn off. You may have a faulty magnetron if your food isn’t heating up correctly or takes too long despite being at full power.

To diagnose problems with a turntable, you’ll need to check the motor and drive coupler to assess its resistance. An overly low resistance is often an indication of a faulty door switch that must be replaced by an experienced technician.

We hope that this guide has been a useful resource to help you get your built-in microwave working as it should. If you need any further help with DIY microwave repair, please don’t hesitate to get in touch with our experienced team.
