Microwave Makes Humming Noise, then Blows Main Fuse? – Splitting The Facts!
Microwaves have become a key kitchen appliance, but when they start making unusual noises and blowing fuses, they can cause trouble.
The reasons behind Microwave Humming Noise are Overloaded Microwave, Faulty Door Switches, High Voltage Diode Failure, and Magnetron Problems. This problem may occur over the passage of time.
Want to fix this problem? Don’t worry! We are going to provide you with effective ways to sort out the fault!
Reasons Why Microwave Makes Humming Noise Then Blows Main Fuse? – Let’s Discuss Them!
One Of The Primary Reason Why Microwave Is Making Annoying Noises Is Overloading:
- Overloading your microwave with containers or food can lead to an electrical overload.
- Microwaves have a specified capacity, and exceeding it can strain the circuitry.
- When you overload the microwave, it draws more power than it can handle, which can cause the main fuse to blow as a safety measure to prevent electrical damage.
- Remember that overloading can also cause the microwave to explode.
Another Main Reason Is Faulty Door Switches:
Moreover, Modern microwaves have multiple door switches that need to engage properly for the appliance to operate safely.
Therefore, If one or more door switches malfunction or fail to close when the door is shut, the microwave may continue running even when the door is open slightly.
This situation can lead to overheating, unusual noises, and potentially fuse blowouts.
Also, High Voltage Diode Failure:
- Further moving on, The high-voltage diode is critical in converting AC power to the high-voltage DC power needed to operate the magnetron.
- When the diode fails, it can create a buzzing sound, and it may cause irregularities in the microwave’s electrical system.
- It can also cause lowering lights in the kitchen.
Magnetron Problems Will Also Lead To Buzzing:
The magnetron is responsible for generating microwave radiation, which heats food. If it malfunctions, it can produce unusual noises and electrical disturbances.
Signs of a problematic magnetron may include a buzzing or humming noise, uneven heating, or failure to heat at all.
Final Point, Aging Capacitor:
- In the end, Capacitors store electrical energy and discharge it to the magnetron when needed. Over time, capacitors can degrade and lose their ability to store energy effectively.
- Remember that a failing capacitor can result in voltage irregularities, which can trigger fuse blowouts.

How to Fix the Microwave Making Humming Noise? – Read One By One!
Firstly, You Have To Do Is, Unplug The Microwave:
Safety should always come first. Before attempting any repairs or inspections, I unplugged the microwave to avoid electrical hazards.
The next thing is Check the Door properly:
- Moreover, I Examined the microwave door carefully for any visible damage, misalignment, or obstructions.
- I also Ensured the door closed securely with no gaps. The door’s proper seal is essential for safety and efficiency.
Now, Test the Door Switches:
Furthermore, A microwave’s door switches are critical safety components. Test them for continuity using a multimeter.
If any of the switches fail the continuity test, they should be replaced immediately.
After that, Examine the High Voltage Diode:
- Always remember that the high-voltage diode can be accessed by removing the microwave’s cover.
- So, Carefully inspect the diode for signs of damage or burn marks. If it appears damaged, replace it with a suitable replacement part.
Then you have to Inspect the Magnetron:
Further moving on, Magnetron issues often require professional interference due to the risks involved.
If you suspect a faulty magnetron, contact a certified technician to diagnose and replace it if necessary.
Lastly, Check the Capacitor:
- So, finally fixing up, If you’re comfortable working with electrical components, you can test the capacitor with a multimeter.
- Discharge the capacitor safely (if applicable), and test it for capacitance and resistance. Replace it if it fails these tests.

How to Avoid Microwave Buzzing Noise Problems in the Future? – Professional Guidance!
Suppose you are afraid of getting this problem in the future. So, Act on these points properly:
- You should Always use microwave-safe containers and utensils that are designed to withstand microwave radiation without melting or releasing harmful chemicals.
- Moreover, Refer to your microwave’s user manual for its recommended capacity, and adhere to these guidelines to prevent electrical overloads.
- You should clean your microwave regularly, especially after spills or splatters, to maintain its functionality and prevent issues.
- Furthermore, When replacing components, use high-quality, manufacturer-recommended parts to ensure safe and reliable operation.
- Also, For complex issues like magnetron replacement or any doubts about safety, consult a professional technician. They have the expertise to handle intricate microwave repairs safely.
So, follow these instructions to prevent this problem in the future; let’s discuss some related questions for next-level understanding!
Frequently Asked Questions:
Can a blown a fuse in the microwave cause a humming noise?
No, a blown fuse doesn’t cause a humming noise. It’s typically the other way around – unusual noises can indicate an underlying issue that leads to a fuse blowing.
Is it safe to continue using a microwave that makes a humming noise?
It’s not advisable to use a microwave that makes strange noises, as it may indicate a problem that could worsen over time. It’s safer to diagnose and fix the issue.
How often should I clean my microwave to prevent issues?
Regularly clean your microwave, especially if you notice food spills or residue. A clean microwave is less likely to experience problems.
Can I replace microwave components myself?
While some components like door switches or capacitors can be replaced by DIY enthusiasts, it’s safer to have a professional handle more complex parts like the magnetron.
What if the issue persists after troubleshooting?
If the problem continues, consult the microwave’s user manual for guidance or contact the manufacturer’s customer support.
In A Nutshell:
Now, I am confident that you know that Microwave Humming Noise is because of Overloaded Microwave, Faulty Door Switches, High Voltage Diode Failure, and Magnetron Problems.
