Fix Your Noisy Microwave: Why Is My Ge Microwave Humming When I Close The Door?

If your GE microwave starts humming when you close the door, it can be a frustrating and confusing issue. This humming noise can be a sign of a minor problem that you can easily fix yourself, or it could indicate a more serious issue that requires professional repair. In this comprehensive troubleshooting guide, we’ll explore the various reasons why your GE microwave may be humming when you close the door and provide step-by-step instructions on how to resolve the issue.

Understanding the Humming Noise

The humming noise that you hear when you close the door of your GE microwave is typically caused by the magnetron, which is the component that generates the microwaves that heat your food. When the magnetron is operating, it produces a high-pitched humming sound. This sound is normal and is not usually a cause for concern.

However, if the humming noise is particularly loud or persistent, it could indicate a problem with the magnetron or other components of the microwave. In these cases, it’s important to troubleshoot the issue and determine the cause of the noise.

Troubleshooting the Humming Noise

1. Check the Door Switch

The door switch is a safety feature that prevents the microwave from operating when the door is open. If the door switch is faulty or misaligned, it can cause the microwave to hum when you close the door. To check the door switch, follow these steps:

• Open the microwave door.
• Locate the door switch, which is typically located on the door frame or the inside of the microwave.
• Press the door switch to see if it clicks.
• If the door switch does not click, it may be faulty and need to be replaced.

2. Inspect the Magnetron

The magnetron is the component that generates the microwaves that heat your food. If the magnetron is faulty or damaged, it can produce a humming noise. To inspect the magnetron, follow these steps:

• Unplug the microwave from the power outlet.
• Remove the outer casing of the microwave.
• Locate the magnetron, which is typically a large, cylindrical component located at the back of the microwave.
• Check the magnetron for any signs of damage, such as cracks or burns.
• If the magnetron is damaged, it will need to be replaced.

3. Check the Capacitor

The capacitor is a component that stores electrical energy and helps to regulate the voltage in the microwave. If the capacitor is faulty or damaged, it can cause the microwave to hum when you close the door. To check the capacitor, follow these steps:

• Unplug the microwave from the power outlet.
• Remove the outer casing of the microwave.
• Locate the capacitor, which is typically a large, cylindrical component located near the transformer.
• Check the capacitor for any signs of damage, such as bulges or leaks.
• If the capacitor is damaged, it will need to be replaced.

4. Check the Diode

The diode is a component that allows electricity to flow in one direction only. If the diode is faulty or damaged, it can cause the microwave to hum when you close the door. To check the diode, follow these steps:

• Unplug the microwave from the power outlet.
• Remove the outer casing of the microwave.
• Locate the diode, which is typically a small, black component located near the transformer.
• Check the diode for any signs of damage, such as cracks or burns.
• If the diode is damaged, it will need to be replaced.

5. Check the Transformer

The transformer is a component that converts the voltage from the power outlet to the voltage required by the microwave. If the transformer is faulty or damaged, it can cause the microwave to hum when you close the door. To check the transformer, follow these steps:

• Unplug the microwave from the power outlet.
• Remove the outer casing of the microwave.
• Locate the transformer, which is typically a large, rectangular component located near the power cord.
• Check the transformer for any signs of damage, such as burns or loose connections.
• If the transformer is damaged, it will need to be replaced.

6. Reset the Microwave

If you have checked all of the components listed above and have not found any signs of damage, you can try resetting the microwave. Resetting the microwave will clear any error codes that may have been stored in the memory and may resolve the humming noise. To reset the microwave, follow these steps:

• Unplug the microwave from the power outlet.
• Wait for 30 seconds.
• Plug the microwave back into the power outlet.
• Check if the humming noise has been resolved.

7. Call a Professional

If you have tried all of the troubleshooting steps listed above and have not been able to resolve the humming noise, you should call a qualified appliance repair technician. The technician will be able to diagnose the problem and make the necessary repairs.

Takeaways: Restoring Your Microwave to Silence

By following the troubleshooting steps outlined in this guide, you should be able to identify and resolve the cause of the humming noise in your GE microwave. Remember, if you are not comfortable performing any of the troubleshooting steps, it is always best to call a qualified appliance repair technician. With a little bit of troubleshooting, you can get your microwave back to working quietly and efficiently in no time.
